Short answer
- Yes, some tooth decay can be stopped without drilling, but only in specific situations, and stopping is not the same as healing. Very early decay, while the enamel surface is still intact, can sometimes be reversed. Dentists call this a noncavitated lesion, and it often looks like a chalky white spot. At this stage, minerals lost from enamel can be replaced through remineralization, helped by fluoride, saliva, and fewer sugar exposures. Fluoride varnish, sealants, and resin infiltration can also help stop these lesions progressing. Decay that has opened a hole, called a cavitated lesion, is different. The missing structure cannot grow back, because mature enamel has no living cells. Silver diamine fluoride can arrest many cavitated lesions in young children's baby teeth, meaning it stops them getting worse, but it does not fill the hole or restore the tooth's shape, and it turns the decayed area dark permanently. The Hall technique can seal decay inside a baby molar under a preformed crown without drilling, but it is a children's technique, and the crown is still a restoration placed by a dentist. Once decay is deep, painful, infected, or badly broken down, non-drilling options run out. A filling or another restorative treatment is then the honest answer, and delay can allow decay to reach the pulp, which is how a manageable cavity becomes a much larger problem, as our explainer on how cavities turn into root canals traces step by step.

Can a cavity be stopped without drilling? Sometimes, yes, and the research behind that answer is genuinely stronger than it was a decade ago. A liquid painted onto a child’s tooth stopped decay in more than half of treated baby teeth in a large 2026 trial. Fluoride varnish, dental sealants, and resin infiltration all have real evidence behind them. Early enamel damage, caught before a hole forms, can sometimes harden again.
But every one of those findings has a boundary, and the boundary is where the hype begins. No treatment in this article regrows a tooth that already has a hole in it. No diet, oil, powder, or supplement in this article rebuilds lost enamel. Arresting decay is not the same as reversing it, preventing a cavity is not the same as treating one, and a result in young children’s baby teeth is not automatically a result for adults.
This article works through the options one by one, naming the actual guideline or study behind each claim, so you can see what the research shows and, just as clearly, what it does not prove. It gives general information only and does not replace a dental examination. If you have tooth pain, swelling, sensitivity that lingers, or a visible hole, see a dentist promptly rather than waiting to see whether a home approach helps. For the wider picture of how decay starts and how it is treated, see our guide to cavities and tooth decay, what they are and how to protect your teeth.
The Line That Decides Everything: Intact Surface or Hole
Almost every argument about healing cavities, honest or dishonest, turns on one distinction. Keeping it in mind will protect you from most misleading claims.
A noncavitated lesion is early decay confined to enamel, or just reaching the outer dentin underneath, with the surface still intact. The enamel has lost minerals and become porous, but it has not collapsed. Because the surface framework is still there, minerals can move back in, and a protective material can be sealed over or into the weakened area. This is the stage where reversal and arrest without drilling are realistic goals.
A cavitated lesion is decay that has broken the surface and created an actual hole. Food and plaque collect inside it, and the bacteria driving the decay are sheltered from a toothbrush. Remineralization cannot rebuild that missing structure, because there is no scaffold left and no living tissue in enamel to do the building. Professional options at this stage aim to inactivate the decay, seal it, or restore the tooth. They do not regrow it.
Dentists judge which side of the line a lesion sits on by examining the tooth, often with X-rays for decay between teeth. That is why no article, video, or product can honestly tell you that your cavity can be healed at home: nobody can know which stage your tooth is at without looking at it. For what a dentist actually does at each stage, see how to get rid of cavities: what actually works and what a dentist does.
How Decay Actually Progresses
The National Institute of Dental and Craniofacial Research, part of the US National Institutes of Health, describes decay as a tug of war that runs all day. On one side, plaque bacteria use sugars and starches to make acids that pull minerals out of enamel. On the other, minerals in saliva, including calcium and phosphate, plus fluoride from toothpaste and water, put minerals back.
Frequency is what tips the balance. Each sugary or starchy exposure starts another acid attack. If attacks come often, through grazing, sweetened drinks sipped over hours, or frequent snacks, mineral loss outruns repair, and a white spot appears where minerals have been lost. The institute is explicit about what follows: decay can be stopped or reversed at the white spot point, but if the process continues, the enamel breaks down into a cavity, and a cavity is permanent damage that a dentist has to repair with a filling. How often sugar reaches the teeth therefore matters at least as much as how much is eaten in total, a pattern our article on sugar and teeth, and why frequency matters most explains in detail. Any no-drilling strategy that ignores sugar frequency leaves the main driver of the disease untouched.
Remineralization: Real, Useful, and Narrow
Remineralization is the natural repair process described above, not a product category. Saliva delivers calcium and phosphate to the enamel surface, and when conditions are right, those minerals redeposit into the porous early lesion and harden it again. Fluoride strengthens the process in three ways the institute lists plainly: it prevents mineral loss, replaces lost minerals, and reduces the ability of bacteria to make acid. It also makes the redeposited mineral more acid resistant than the original enamel mineral.
The everyday tools of remineralization are unglamorous: brushing twice a day with fluoride toothpaste, spitting rather than rinsing heavily afterward so fluoride stays in contact with the teeth, cleaning between the teeth, and cutting the number of sugary exposures so saliva gets time to repair between acid attacks. None of it can be sold as a breakthrough, which is why it is marketed so poorly.
The limits matter as much as the mechanism. Remineralization works on the surface of an intact lesion; dentists monitor such lesions over time to confirm they have become inactive. It cannot fill a hole, rebuild a collapsed biting surface, or reach decay that has spread deep into dentin under an intact looking surface. A remineralizing white spot is a success story for early detection, not evidence that cavities in general can heal themselves. One habit can quietly undo the benefit: rinsing with mouthwash immediately after brushing washes away the concentrated fluoride toothpaste leaves behind, a timing issue covered in our guide to mouthwash before or after brushing.
Fluoride Varnish: Professional Prevention With Solid Numbers
Fluoride varnish is a concentrated fluoride coating a professional paints onto the teeth, where it sets on contact with saliva and releases fluoride over the following hours. It is used mainly to prevent new decay and help early lesions, especially in children at higher risk, and it takes only a few minutes with no drilling.
The strongest summary of its effect comes from a Cochrane review by Marinho and colleagues in 2013. Pooling 22 trials with 12,455 children and adolescents, it found fluoride varnish applied two to four times a year associated with a prevented fraction of 43 percent in permanent teeth and 37 percent in baby teeth, meaning roughly that share of new decayed, missing, or filled surfaces was avoided versus placebo or no treatment. The reviewers rated the evidence moderate quality, not high, because many trials carried some risk of bias. The Centers for Disease Control and Prevention gives a simpler summary: varnish can prevent about one third of cavities in baby teeth.
Read those numbers carefully, because they are often inflated in retelling. Varnish reduces new decay; it does not eliminate decay, it does not treat an established hole, and the Cochrane figures describe prevention over years of repeated application, not a single visit curing anything. The American Dental Association’s 2018 guideline on nonrestorative treatments, published in the Journal of the American Dental Association, recommended 5 percent sodium fluoride varnish, alone or with sealants, among its priority options for arresting or reversing noncavitated lesions. That is a professional endorsement for a defined, early job, not a blanket promise.
Silver Diamine Fluoride: The Strongest New Evidence, With Real Trade-Offs
Silver diamine fluoride, usually shortened to SDF, is the treatment behind most current headlines about stopping cavities without drilling, and unusually for a headline treatment, substantial research sits behind it. It is a clear liquid a professional paints onto decay with a small applicator. The silver acts against the bacteria driving the decay, and the fluoride helps strengthen the remaining tooth mineral, as the National Institute of Dental and Craniofacial Research summarizes it. The goal is arrest: soft, active decay hardens and stops progressing. Application takes seconds per tooth, with no drilling, injection, or sedation.
What the large 2026 trial found
The most rigorous test so far is a Phase III randomized clinical trial led by Margherita Fontana at the University of Michigan School of Dentistry, with partners at New York University, the University of Iowa, and Indiana University, funded by the National Institute of Dental and Craniofacial Research and published in JAMA Pediatrics in 2026. It enrolled 830 children aged 12 to 71 months with severe early childhood caries, recruited through dental offices, pediatric practices, and Head Start programs in Michigan, New York, and Iowa. Children received either 38 percent silver diamine fluoride or a placebo, at the start of the study and again at six months, and examiners judged arrest by whether the decayed area had hardened.
At six months, after a single application, SDF had arrested 54.0 percent of treated cavities, compared with 22.5 percent with placebo. The institute’s report of the trial’s earlier analysis of 599 children gave a closely matching result, 54 percent against 21 percent, with no safety concerns identified, and the trial was stopped early because it had met its primary endpoint.
That is a strong result, with clear edges. Roughly half of the treated cavities were not arrested. The children were under six, with baby teeth and severe early decay, so the trial does not establish the same success rate for adults or permanent teeth. Follow up ran to eight months, which cannot show longer-term outcomes, and about 3 in 10 children were lost to follow-up.
What guidelines already said, and what SDF does not do
The trial reinforced guidance that already existed. The American Dental Association’s 2018 nonrestorative guideline prioritized biannual 38 percent SDF for arresting advanced cavitated lesions in baby teeth. The systematic review and network meta-analysis behind it, by Urquhart and colleagues in the Journal of Dental Research in 2019, pooled 44 trials with 7,378 participants and found biannual 38 percent SDF the most effective option for advanced cavitated lesions, at moderate to high certainty.
The trade offs are not minor. SDF permanently stains the decayed part of the tooth black; sound enamel is not stained, but an arrested front tooth cavity is visibly dark. SDF does not restore shape, so a hole that trapped food still traps food, now hardened and inactive. It is a professional treatment, not a home remedy, and in the United States it is cleared by the Food and Drug Administration for tooth sensitivity and used off label for decay, as the institute states openly. A tooth with pain, swelling, or signs of infection is not an SDF case to watch; it needs prompt assessment and may need a different treatment. If SDF is used for your child, our guide to silver diamine fluoride aftercare explains what to expect afterward.
Resin Infiltration: Sealing Early Decay Between Teeth
Resin infiltration tackles a specific problem: early decay on the surfaces where two teeth touch, called proximal or approximal surfaces. These lesions are hard to clean, hard to see without X-rays, and awkward to treat, because reaching them with a drill means cutting through healthy tooth. Infiltration avoids that. A very fluid resin is drawn into the porous body of the noncavitated lesion, where it hardens into a barrier inside the enamel that blocks acids and slows or stops progression.
The evidence is genuinely supportive, within its narrow indication. A Cochrane review by Dorri and colleagues in 2015 concluded that micro invasive treatment, including resin infiltration and sealing, arrests noncavitated enamel and early dentinal proximal lesions and is significantly more effective than non invasive measures alone, such as fluoride varnish or flossing advice. The reviewers were moderately confident, while noting that few studies left unclear which micro invasive technique was best. The American Dental Association’s 2018 guideline likewise lists resin infiltration, with 5 percent sodium fluoride varnish, for noncavitated approximal lesions in primary and permanent teeth.
The boundaries are strict. Once the surface has collapsed into a hole, resin cannot recreate the missing contour, and a conventional restoration is usually needed. It is a technique sensitive procedure done by a dentist, often guided by X-ray depth, not a coating you apply at home: a way to avoid drilling into an early between teeth lesion, not a way to reverse established cavities.
Sealants: Prevention on Chewing Surfaces, Not a Cure
Dental sealants are thin resin coatings painted into the pits and grooves on the chewing surfaces of back teeth, then hardened, so plaque and food cannot settle there. They belong here as a no drilling intervention with unusually clear public health numbers, and because the American Dental Association’s 2018 guideline recommends sealants, alone or with fluoride varnish, as a priority option for arresting or reversing noncavitated lesions on chewing surfaces.
The Centers for Disease Control and Prevention’s Vital Signs report on sealants states the prevention figures plainly. Sealants prevent 80 percent of cavities in the back teeth, where nine in ten cavities occur, during the first two years after placement, and they continue to protect against about 50 percent of cavities for up to four years. School age children without sealants have almost three times more cavities in their first permanent molars than children with sealants.
Those are prevention statistics for teeth sealed soon after the molars come through. A sealant does not treat a deep or painful cavity, and sealants need checking at routine visits, because a chipped or lost sealant leaves the groove exposed again. Used at the right time, though, they are among the best supported ways to keep a back tooth from ever needing a drill.
The Hall Technique: Sealing a Baby Molar Under a Crown
The Hall technique surprises people most. Developed in Scotland and named after general dental practitioner Norna Hall, it manages decay in a baby molar by cementing a preformed metal crown directly over the decayed tooth, with no drilling, no removal of decay, no injection, and no tooth preparation. The idea is biological: sealed away from the sugars that feed them, the bacteria in the lesion become inactive, and decay stops progressing under the crown.
Trials support it for its specific job. In a randomized clinical trial in Sudan, published in PLOS ONE, 212 preformed metal crowns were placed in children aged five to eight, half by the Hall technique and half conventionally. After two years, survival was over 90 percent in both groups with no statistically significant difference, while Hall technique appointments averaged 9.1 minutes against 33.9 minutes and cost less. Reviews pooling the randomized trials report success in a similar high range for both approaches, with the Hall technique consistently quicker and well accepted by parents.
Context is everything here. The Hall technique is only for baby molars where the nerve is not already irreversibly inflamed or infected, and it is still a restoration: the tooth ends up wearing a visible metal crown, and the bite sits slightly high until it settles. It avoids the drill, but not the dentist, and it has nothing to offer an adult with a decayed permanent molar.
What About Adults, Root Surfaces, and High Strength Fluoride?
Most of the headline research is about children, but some of it applies to adults, with the same stage limits. The American Dental Association’s 2018 guideline covers permanent teeth as well as baby teeth. For decay on exposed root surfaces, a mainly adult problem because roots have no enamel covering and decay faster, its priority recommendation is daily use of a prescription strength 5,000 parts per million fluoride toothpaste or gel. The pattern for adults is consistent: the no drilling toolkit is real, but it is prescribed and monitored, not improvised.
Evidence for SDF in adults is thinner than the pediatric trial evidence, and honest reporting should say so rather than borrow the children’s numbers. Older adults can also face dry mouth from medicines, receding gums, and difficulty cleaning around existing crowns and bridges, all of which raise decay risk. If you hope to avoid a filling, the useful questions are whether your specific lesion is noncavitated, whether it is active or already arrested, and what monitoring interval your dentist proposes. A lesion being watched should always have a review plan attached to it.
Claims That Do Not Hold Up
Set against the measured findings above, the popular healing claims fail in recognizable ways. They promise complete regrowth rather than arrest, present testimonials instead of trials, often blame fluoride or dentistry itself, and usually have a product, diet plan, or supplement range for sale behind them. Specific examples deserve specific answers, including the enamel regrowth products covered in our article on gel that regrows tooth enamel.
Oil pulling
The American Dental Association’s position, restated in its news coverage of the trend, is that there are no reliable scientific studies showing that oil pulling reduces cavities, whitens teeth, or improves oral health and well being, and on that basis it does not recommend it as a dental hygiene practice. Swishing oil may not be harmful for most people, but an unproven ritual becomes a problem when it replaces fluoride toothpaste, cleaning between the teeth, or a dental visit for a tooth that is actively decaying.
Charcoal and abrasive scrubs
A literature review in the Journal of the American Dental Association in 2017, by Brooks and colleagues, found insufficient clinical and laboratory evidence to substantiate the safety and efficacy claims made for charcoal based dentifrices. Charcoal products work, to the extent they work at all, by abrasion, and abrasion removes enamel as well as stain. Baking soda scrubs and other gritty home powders carry the same problem: wearing away the tissue you are trying to protect is the opposite of remineralization.
Diets, vitamins, and regrowth products
Nutrition genuinely matters for teeth, and sugar frequency drives decay. Historical research on nutrition and tooth development is sometimes used to claim far more: that a particular diet, or high dose vitamin regimen, can regrow teeth or heal established cavities. No clinical trial evidence supports that, and the biology rules it out. The cells that build enamel, called ameloblasts, are lost when the tooth comes through into the mouth, and mature enamel contains no living cells, which is why it cannot regenerate itself once lost. Laboratory work on growing enamel like material is real research, but it is not a treatment you can buy.
The common thread is what the claims ask you to give up. A claim that requires abandoning fluoride, skipping dental assessment, and buying an unproven product instead asks you to trade interventions with named trials and guidelines behind them for a story. When pain, swelling, or a broken tooth is in the picture, that trade can cost the tooth.
When a Filling Is Still the Answer
Non-drilling care has limits, and recognizing them early is part of using it well. See a dentist promptly, rather than monitoring at home, if you notice pain that starts on its own or lingers after hot, cold, or sweet stimuli; swelling of the gum or face; a visible hole, a broken or crumbling tooth, or a growing dark area; or a bad taste or pimple like bump on the gum near a tooth.
At that point the realistic options are restorative: a filling, a crown over a weakened tooth, pulp treatment if decay has reached it, or, where a tooth cannot be saved, removal. The overview of how to get rid of cavities and what treatment involves sets out those options in full. That is not a failure of prevention. It is the correct treatment for a stage prevention can no longer reach, and prompt treatment is what keeps a small filling from becoming a root canal treatment or an extraction later.
Questions Worth Asking Your Dentist
If you would like to avoid drilling where that is safely possible, these questions turn the research into a conversation: Is this lesion cavitated or noncavitated? Is it active, or already arrested? Could fluoride varnish, a sealant, resin infiltration, or silver diamine fluoride suit this tooth, and what would each mean for appearance and follow up? If we monitor it instead of filling it, when will you recheck it, and what change would trigger treatment? Is my decay risk high, and should I be using a higher strength fluoride toothpaste? Monitoring based care depends on you understanding the plan and returning for the checks that make it safe, so a dentist offering it will usually welcome the questions.
Frequently Asked Questions
Can a cavity heal itself naturally?
Only the earliest stage can reverse. A white spot where enamel has lost minerals, but the surface is still intact, can sometimes reharden through remineralization, helped by fluoride, saliva minerals, thorough cleaning, and fewer sugar exposures. A cavity that has formed a physical hole cannot heal itself or regrow enamel, because mature enamel has no living cells. Only an examination can establish which stage a particular tooth has reached.
Is silver diamine fluoride a cure for cavities?
No. Silver diamine fluoride can arrest decay, meaning it stops it progressing, and in the large JAMA Pediatrics trial reported in 2026 it arrested 54.0 percent of treated cavities in young children at six months, compared with 22.5 percent with placebo. It does not rebuild lost tooth structure, it does not work on every cavity, it permanently darkens the treated decay, and it is applied by a professional after assessment. It is best understood as a way to stop a suitable lesion and buy stability, not as a cure that restores the tooth.
Can fluoride varnish repair a cavity?
Fluoride varnish helps prevent new decay and can help arrest or reverse early noncavitated lesions. A Cochrane review found it associated with 43 percent fewer new decayed, missing, or filled surfaces in permanent teeth and 37 percent fewer in baby teeth across trials in children and adolescents. It cannot repair a hole. Once a lesion has cavitated, varnish alone is not a treatment for that cavity.
What is the difference between arresting and reversing decay?
Reversing means an early lesion loses its signs and the enamel rehardens, possible only before cavitation. Arresting means an active lesion, including some cavitated lesions treated with silver diamine fluoride or sealed under a Hall technique crown, becomes hard and inactive, while the lost structure stays lost. Arrest is a genuine clinical success, but marketing that presents it as regrowth is misleading you.
Do sealants and resin infiltration work on existing cavities?
Both work on early, noncavitated lesions, in different places. Sealants protect and can help arrest early lesions in the grooves of chewing surfaces, and the Centers for Disease Control and Prevention reports they prevent 80 percent of back tooth cavities for the first two years. Resin infiltration treats early lesions between teeth by sealing resin into the porous enamel. Neither treats a deep, painful, or badly broken down cavity.
Can adults stop cavities without drilling too?
Sometimes, under the same rules. Early noncavitated lesions in permanent teeth can be managed with fluoride, sealants, or resin infiltration, and the American Dental Association guideline includes permanent teeth, including daily 5,000 parts per million fluoride toothpaste or gel as the priority option for root surface lesions. The strongest silver diamine fluoride evidence is in young children, so adults should not assume the same success rates. Ask your dentist whether your lesion qualifies and how it will be monitored.
Does oil pulling or charcoal heal cavities?
There is no reliable evidence that either heals cavities. The American Dental Association states there are no reliable studies showing oil pulling reduces cavities, and it does not recommend the practice. A 2017 review in the Journal of the American Dental Association found insufficient evidence for the safety and efficacy claims of charcoal dentifrices, which act by abrasion and can wear enamel. Neither replaces fluoride, cleaning, or dental treatment.
