Suboxone and dental problems: the FDA warning on tooth decay

Medically reviewed by [Reviewer name, credentials] · Last updated October 17, 2026

You bite into a piece of toast and feel something small and hard on your tongue. A corner of a back molar has broken off. It does not even hurt much, which somehow makes it more unsettling. You have been on Suboxone for over a year, doing well, and now you are wondering whether the medicine that saved your life is quietly costing you your teeth.

That worry is fair, and it has a name: Suboxone tooth decay. In 2022 the FDA formally warned that buprenorphine medicines that dissolve in the mouth have been linked to cavities, infections, and tooth loss. The good news is that the same warning came with practical steps, and none of them involve giving up treatment.

What the FDA Found About Suboxone Tooth Decay

The FDA reviews reports that doctors, pharmacists, and patients send in about problems with medicines. When the agency looked at buprenorphine products placed under the tongue (sublingual) or inside the cheek (buccal), it found a pattern of dental harm that kept showing up. You can read the original FDA dental warning on buprenorphine for the agency’s full wording.

Some of the people affected were young, and some had no history of dental trouble before their Suboxone tooth decay was found. That detail helped convince the FDA that the medicine itself, or the way it is taken, likely plays a role, rather than everything being explained by past dental neglect.

As a result, the FDA required new warnings in the prescribing information and in the Medication Guide that comes with every prescription. The agency also asked prescribers to talk about oral health when starting treatment and to refer patients for dental care.

Reading those numbers carefully

Three hundred five cases may sound small next to the large number of people who take buprenorphine. Keep in mind that voluntary reports usually capture only a fraction of real events. Dental problems are also easy to overlook: a person might never connect a cracked tooth to a medicine, and a dentist might never file a report. So the true count of Suboxone tooth decay cases is unknown, and the number should be read as a signal, not a precise rate.

On the other side, these reports cannot prove that buprenorphine caused each problem. Many people starting treatment already have dental needs. The honest summary is that a real link appears likely, the exact size of the risk is unclear, and simple habits can lower it.

Does Suboxone Rot Your Teeth? Possible Reasons Why

Nobody has proven exactly why dissolving buprenorphine harms teeth or what drives Suboxone tooth decay in one person and not another. The ideas below are proposed explanations that researchers and dentists have raised. More than one may be at work for any given person.

Acidity of the dissolving medicine

Suboxone films and tablets are made to dissolve in the mouth, and that formula tends to be acidic. Tooth enamel starts to lose minerals when the mouth turns acidic. Picture holding a sip of soda against your teeth for several minutes, once or twice a day, every day for years. Even mild acid adds up when the exposure repeats that often.

Long contact time

A film or tablet can take several minutes to fully dissolve, and people are told not to swallow, chew, or talk during that time. Then many people avoid drinking afterward so they do not “waste” the dose. That means the medicine and its acidic residue sit right against the teeth and gums longer than most foods or drinks would.

Dry mouth

Saliva is the mouth’s built-in rinse. It washes away food, neutralizes acid, and carries minerals back into enamel. Opioids, including buprenorphine, can reduce saliva flow. Less saliva means acid lingers and bacteria have an easier time.

Sugar cravings

Many people in recovery notice strong cravings for sweets, soda, and energy drinks. Sugar feeds the bacteria that make cavity-causing acid. Combined with dry mouth, a sugary diet can speed decay.

Dental care that slipped during active use

Active opioid use often comes with missed dental visits, irregular brushing, teeth grinding, and limited money for care. Damage that started years ago may only become visible later. Since full agonist opioids also dry the mouth, some decay found during treatment may have begun before it.

Who Faces a Higher Risk of Buprenorphine Tooth Loss

Anyone who takes a dissolving form of buprenorphine can develop dental problems, but some people start with less margin for error. Knowing where you stand helps you decide how hard to lean on prevention.

• People with existing cavities or gum disease. Weak spots in enamel and inflamed gums give acid and bacteria an easy start.
• People who take more than one dose a day. Each dose is another round of acid contact, so twice-daily dosing means twice the exposure.
• People with dry mouth from other medicines. Many antidepressants, antihistamines, blood pressure pills, and anxiety medicines also reduce saliva.
• Smokers and vapers. Tobacco and nicotine products dry the mouth and harm gums.
• People who sip sweet or acidic drinks all day. Soda, energy drinks, sports drinks, and sweetened coffee keep the mouth acidic for hours.
• People who grind their teeth. Grinding wears down enamel that acid has already softened.
• Pregnant people. Hormone changes can make gums swell and bleed more easily.

If several of these apply to you, it does not mean Suboxone tooth decay is certain. It means a dental visit soon after starting is especially worth the effort, and that extra fluoride is worth asking about.

Which Buprenorphine Products the Warning Covers

The warning applies to buprenorphine that dissolves in the mouth. It does not apply to every product that contains buprenorphine. The table sorts the most common ones. If you are not sure how the brand and generic names line up, our guide to buprenorphine vs Suboxone sorts them out.

Product type	Examples	Covered by the 2022 dental warning?
Sublingual film (buprenorphine + naloxone)	Suboxone film, generic films	Yes
Sublingual tablet (buprenorphine + naloxone)	Generic tablets, Zubsolv	Yes
Sublingual tablet (buprenorphine only)	Generic buprenorphine, formerly Subutex	Yes
Buccal film (dissolves against the cheek)	Buccal buprenorphine products, including the discontinued Bunavail	Yes
Extended-release injection	Sublocade, Brixadi	No concern identified for Sublocade; injection does not dissolve in the mouth
Skin patch	Butrans (for pain)	No concern identified
Injection for pain	Buprenex	No concern identified

The FDA specifically said it had not identified this problem with the patch or with Sublocade and Buprenex injections. Brixadi was approved after the 2022 warning, but because it is injected rather than dissolved in the mouth, the same reasoning applies. Ask your prescriber how your specific product fits.

The After-Dose Routine to Protect Your Suboxone Teeth

The FDA’s advice is short and easy to follow. Here it is as a routine you can do every time you take your dose.

1. Let the film or tablet dissolve completely. Do not chew, swallow, or move it around. This keeps the dose working as it should.
2. Take a large sip of water. Once nothing is left in your mouth, take a generous mouthful of plain water.
3. Swish gently. Move the water around your teeth and gums for a few seconds. No hard gargling needed.
4. Swallow it. The FDA advice is to swallow the water rather than spit it out.
5. Wait at least one hour before brushing. Acid softens enamel for a short while. Brushing right away can scrub away the softened surface. Waiting lets saliva start to repair it.
6. Brush and floss later as normal. Use a fluoride toothpaste and a soft brush.

Will rinsing reduce my dose?

Not if you wait until the medicine has fully dissolved. By then the buprenorphine has been absorbed through the tissue under your tongue or in your cheek. The sip of water clears leftover residue from your teeth. If you are unsure whether your film has fully dissolved, ask your prescriber or pharmacist to walk through it with you.

A Daily Plan for Buprenorphine and Your Teeth

The after-dose routine is the heart of preventing Suboxone tooth decay, but daily habits do the rest. Think of your enamel as a bank account. Acid and sugar make withdrawals all day long. Saliva, fluoride, and good habits make deposits. Your goal is to keep the balance positive.

Fluoride, every day

Brush twice a day with a fluoride toothpaste. Fluoride helps enamel rebuild after acid attacks and makes it more resistant to the next one. After brushing, spit out the extra toothpaste but skip rinsing with water, so a thin film of fluoride stays on your teeth longer.

Ask about prescription-strength fluoride

If you already have cavities or a dry mouth, a dentist may suggest a high-fluoride toothpaste, a fluoride varnish painted on at the office, or a fluoride rinse. These are common, affordable, and well-studied tools for people at high risk of decay, including Suboxone tooth decay.

Fight dry mouth

• Sip plain water through the day. Keep a refillable bottle with you.
• Chew sugar-free gum or suck on sugar-free lozenges, especially those sweetened with xylitol, which may also make it harder for cavity bacteria to thrive.
• Limit caffeine and alcohol, which can dry the mouth further.
• Try a cool-mist humidifier at night if you wake with a dry mouth.
• Ask your dentist or pharmacist about saliva substitutes if dryness is severe.

Rethink sweet drinks and snacks

You do not need a perfect diet. What matters most is how often sugar touches your teeth. Sipping a sweet coffee or soda over two hours is harder on enamel than drinking it with a meal. Swap one daily sugary drink for water or unsweetened tea, keep sweets to mealtimes, and rinse with water after a sugary snack. For many people, sugar cravings ease as treatment stabilizes.

Mind the grinding

Stress and sleep problems are common in early recovery, and many people clench or grind their teeth at night. If you wake with sore jaws or notice flat, chipped edges on your teeth, a dentist can fit a night guard. Our guide to the effects of stress on the body offers ideas for easing tension.

What to Tell Your Dentist About Suboxone Dental Problems

The FDA asks people who take buprenorphine to tell their dentist, and to get a dental check soon after starting. Many people feel nervous about sharing their treatment, worried about judgment. Dentists see patients on many medicines, and the information helps them protect you. You do not need to share your whole history. A few clear sentences are enough.

Here is a simple script you can adapt:

• “I take buprenorphine, as a film under my tongue, once (or twice) a day.”
• “I’ve read about the FDA warning on dental problems, and I’d like to take steps to prevent them.”
• “My mouth often feels dry,” or “I’ve noticed a broken tooth / sensitivity / sore gums.”
• “Should I be using prescription fluoride, or coming in more often?”
• “If I need a procedure, what are the options for pain control that work with my treatment?”

That last point is worth planning ahead. Buprenorphine holds tightly to opioid receptors, which can blunt the effect of some opioid pain medicines. Dentists can usually manage procedure pain well with local anesthetic and non-opioid medicines. Your prescriber and dentist should talk if a bigger procedure is coming up. Our article on whether Suboxone helps with pain explains more.

How often should you go?

The FDA recommends a dental check soon after starting buprenorphine and regular checkups after that. Your dentist will set the schedule based on what they find. People with dry mouth or a history of decay often benefit from cleanings more than twice a year.

Should You Switch Formulations Because of Suboxone Tooth Decay?

If you have had serious dental problems, it is reasonable to ask whether a different form of buprenorphine makes more sense. Extended-release injections like Sublocade (monthly) and Brixadi (weekly or monthly) skip the mouth entirely. For some people, that also means one less daily task to remember.

Switching is a medical decision, though, not a quick swap. Injections may not suit everyone, insurance coverage varies, and moving between products needs a plan from your prescriber. Bring it up at your next visit, ideally with your dentist’s notes in hand.

Weighing other treatment options is also fair. Methadone is a liquid that is swallowed, and naltrexone comes as a pill or monthly injection. Each has its own benefits and drawbacks, covered in our comparisons of Suboxone vs methadone and naltrexone vs Suboxone. Methadone and other opioids can also dry the mouth, so good dental habits matter on any of them.

Finding Affordable Dental Care

Cost is one of the biggest reasons people skip the dentist. If money is tight, these options are worth checking:

• Community health centers. Federally funded health centers offer care on a sliding fee scale based on income, and many include dental clinics. The Health Resources and Services Administration (HRSA) runs a “Find a Health Center” search tool online.
• Dental schools. Students treat patients under close supervision by licensed dentists, often at a lower cost. Appointments can take longer, but the care is careful.
• Medicaid dental benefits. Adult dental coverage varies a lot by state. Call your plan and ask what is included.
• Your treatment program. Some opioid treatment programs and clinics have dental partners or referral lists. Ask your counselor or care coordinator.
• Free dental events. Local charities and dental associations sometimes host free clinic days.

Even if you cannot get a full exam right away, the best defenses against Suboxone tooth decay are cheap: the after-dose routine and fluoride toothpaste start helping on day one.

A Brief Note on Lawsuits

Since the 2022 warning, people who say they suffered dental damage from sublingual buprenorphine have filed lawsuits against manufacturers. These cases make claims about whether drug makers warned about the risk soon enough. The cases are ongoing, and their outcome does not change the medical advice. If you are curious about legal options, speak with a licensed attorney. Do not change your medicine because of a lawsuit ad.

Warning Signs to Watch For

Catching Suboxone tooth decay early keeps treatment simpler and cheaper. Call your dentist if you notice:

• Tooth sensitivity to hot, cold, or sweet
• Brown, black, or white chalky spots on teeth
• Small chips or rough edges, especially near the gumline
• Bleeding, swollen, or receding gums
• Persistent bad breath or a bad taste
• A loose tooth

Get same-day care for facial swelling, fever with tooth pain, or swelling that spreads toward the eye or neck. Those can be signs of a spreading infection.

Suboxone Teeth FAQ

Does Suboxone rot your teeth?

Suboxone tooth decay does not happen to every person, but the FDA has linked buprenorphine that dissolves in the mouth to tooth decay, cavities, infections, and tooth loss. The risk seems to come from how the medicine is taken, along with dry mouth and diet. Rinsing with water after each dose and good dental care can lower the risk.

When did the FDA warn about Suboxone and teeth?

The FDA issued its Drug Safety Communication on January 12, 2022. It identified 305 reports of dental problems with buprenorphine dissolved in the mouth, including 131 serious cases. The agency required new warnings on the labels and Medication Guides.

How do I protect my teeth on Suboxone?

After the film or tablet fully dissolves, take a large sip of water, swish gently, and swallow. Wait at least one hour before brushing. Use fluoride toothpaste, drink water through the day, limit sugary drinks, and see a dentist soon after starting and regularly after that.

Why should I wait an hour to brush after Suboxone?

The dissolving medicine is acidic, and acid briefly softens tooth enamel. Brushing right away can wear away that softened layer. Waiting an hour gives saliva time to help harden the enamel again.

Does Sublocade cause tooth decay?

The FDA said it had not identified dental problems with Sublocade, which is injected under the skin rather than dissolved in the mouth. Brixadi, also an injection, works the same way. Opioids can still dry the mouth, so regular dental care is still wise.

Are Suboxone films worse for teeth than tablets?

The FDA warning covers both sublingual films and tablets, as well as buccal forms, and did not single out one as worse. Any buprenorphine that dissolves in the mouth carries the same advice. Ask your prescriber if you have concerns about your specific product.

Should I stop Suboxone if my teeth are getting worse?

No. Stopping suddenly can cause withdrawal and raise the risk of relapse and overdose. Talk with your prescriber about protecting your teeth, and about whether an injectable form might suit you better.

Does Suboxone during pregnancy affect teeth?

Pregnancy itself can make gums more sensitive and raise the risk of dental problems, so the after-dose routine is especially useful. Dental care is safe and recommended during pregnancy. Our guide to Suboxone during pregnancy covers other questions about treatment while expecting.

The Takeaway

Suboxone tooth decay is a real concern backed by an FDA warning, but it is also one of the more manageable risks in recovery. Let each dose dissolve fully, rinse and swallow a mouthful of water, wait an hour to brush, and lean on fluoride and plain water through the day. Tell your dentist you take buprenorphine and get checked soon. If your teeth keep getting worse, ask your prescriber about other forms rather than stopping. Your treatment and your smile can both be protected. To understand the medicine itself better, read how Suboxone works.
