Suboxone and Your Teeth: Dental Health on Buprenorphine

You've finally found a medication that's helping you build a stable life in recovery. Then during a routine dental cleaning, your hygienist mentions some unexpected erosion or cavities. If you're taking Suboxone (buprenorphine) sublingually—dissolved under your tongue—you might be wondering if there's a connection.

The short answer: yes, there can be. In 2022, the FDA issued a safety communication about dental problems associated with sublingual buprenorphine products, including tooth decay, cavities, and in severe cases, tooth loss. The good news? These risks are preventable with the right oral hygiene routine, and they absolutely don't outweigh the life-saving benefits of staying on treatment.

This guide explains what we know about buprenorphine and dental health, why the risk exists, and exactly what you can do to protect your teeth while staying on the medication that's working for you.

What the FDA warning actually says

The FDA safety communication wasn't meant to scare people off treatment—it was meant to alert patients and providers so they could take preventive action. The warning specifically applies to buprenorphine products that dissolve in your mouth: sublingual tablets, sublingual films, and buccal films (placed inside your cheek).

The FDA reviewed 305 case reports of dental problems in patients using these products between 2012 and 2022. Many patients reported good dental health before starting buprenorphine, and some developed severe issues within just months of beginning treatment. Problems ranged from cavities and tooth sensitivity to cracked teeth and tooth loss requiring extractions or implants.

Other buprenorphine formulations do not have the same direct oral exposure. If dental issues are a concern, ask the prescriber whether another formulation is clinically appropriate, then verify the exact product's coverage and administration requirements with the insurer.

Why buprenorphine affects your teeth

The mechanism isn't fully understood, but researchers believe it's a combination of factors working together.

Acidic pH: Sublingual buprenorphine products have a low pH (they're acidic), which can weaken tooth enamel over time. When you hold the film or tablet under your tongue for 5–15 minutes while it dissolves, that acidic environment bathes your teeth. Enamel erosion leaves teeth vulnerable to decay and sensitivity.

Dry mouth: Like many medications, buprenorphine can reduce saliva production. Saliva is your mouth's natural defense system—it neutralizes acids, washes away food particles, and contains minerals that help repair early tooth damage. Less saliva means more risk. You might have noticed this as a common side effect when you first started Suboxone.

Prolonged contact: Because the medication dissolves slowly, your teeth are exposed to the film or tablet for an extended period each day—sometimes twice daily. That's different from swallowing a pill, where contact time is brief.

Behavioral factors: Some people in early recovery are rebuilding basic self-care habits, including dental hygiene. Substance use often takes priority over preventive health care, so returning to consistent brushing and flossing can take time. There's no shame in this—it's part of the recovery process we help patients work through in counseling alongside medication treatment.

It's worth noting that opioid use disorder itself is associated with poor oral health, often from years of neglect, dry mouth from drug use, sugar cravings, and difficulty accessing care. Buprenorphine treatment gives you the stability to finally address these issues—but only if you know how to protect your teeth while on the medication.

How to protect your teeth while taking Suboxone

The FDA recommendations are straightforward and highly effective if you follow them consistently. Think of this as part of your daily recovery routine—just as important as taking your medication on time.

Right after dosing

Wait one hour, then brush: After your Suboxone film or tablet has completely dissolved, wait at least one hour. Then brush your teeth thoroughly with fluoride toothpaste. Brushing immediately after dosing can actually make things worse by scrubbing acid into your enamel.

Rinse with water: During that one-hour waiting period, rinse your mouth with plain water several times. Swish it around and spit—this helps neutralize the acidic pH and wash away residue. Some patients keep a water bottle nearby as a reminder.

Consider a pH-neutralizing rinse: Some dentists recommend using a pH-neutralizing or baking soda rinse after dosing. Mix 1/4 teaspoon of baking soda in 8 oz of water, swish for 30 seconds, and spit. Talk with your dentist before adding this step.

Daily oral hygiene

Brush twice daily with fluoride toothpaste: Morning and night, two minutes each time. Use a soft-bristled brush and gentle circular motions. Replace your toothbrush every three months.

Floss once daily: Between-teeth decay is common with sublingual medications. Floss before bedtime to remove particles your toothbrush can't reach.

Use fluoride mouthwash: After brushing at night, rinse with an alcohol-free fluoride mouthwash. Fluoride strengthens enamel and helps repair early damage. Look for products with at least 0.05% sodium fluoride.

Stay hydrated: Drink water throughout the day to combat dry mouth. Keep a water bottle with you. Avoid sugary drinks, which accelerate tooth decay.

Sugar-free gum or lozenges: If dry mouth is severe, chew sugar-free gum with xylitol between doses. This stimulates saliva production. Avoid regular gum or candy, which add sugar to an already vulnerable environment.

Professional dental care

See a dentist every six months: Regular cleanings and exams catch problems early, when they're easier and cheaper to fix. Be upfront about your buprenorphine treatment so your dentist can tailor preventive care.

Fluoride varnish treatments: Ask about professional fluoride applications during your cleanings. These provide extra protection for enamel.

Address problems immediately: Don't wait if you notice sensitivity, discoloration, or pain. Early intervention can save a tooth that might otherwise require extraction.

Many patients avoid the dentist due to cost, anxiety, or past stigma around addiction. We get it. But dental care is an essential part of staying healthy on Suboxone, and there are resources that can help.

Does insurance cover dental care for Suboxone patients?

The answer depends on your insurance type and state.

Medicaid: Adult dental coverage under Medicaid varies widely by state. Virginia Medicaid and Ohio Medicaid provide emergency dental services for adults, but routine preventive care may be limited. Pennsylvania's Medicaid program offers more comprehensive adult dental benefits in some counties. Check with your state's Medicaid office for details.

Commercial insurance: If you have coverage through Aetna, BCBS, Cigna, or another commercial insurer, your medical plan likely doesn't include dental—those are separate policies. However, some plans offer discounted dental networks or health savings accounts (HSAs) you can use for dental care.

Community health centers: Some Federally Qualified Health Centers provide dental services or referrals and may use sliding-fee programs. Confirm services, eligibility, and current payment options with the center.

Dental schools: University dental schools offer low-cost care provided by students under faculty supervision. It's safe, thorough, and significantly cheaper than private practice. Search for "[your city] dental school clinic" to find options.

Opioid settlement funds: Some states are using opioid settlement money to expand treatment and support services, including dental care for people in recovery. Ask your treatment provider about available programs—this is an evolving landscape with new resources becoming available.

If insurance or cost is a barrier, ask the dental office, insurer, or a local health center about current payment and referral options. Do not delay urgent dental evaluation while waiting for an addiction-treatment appointment.

Should you switch from Suboxone film to tablets (or vice versa)?

Both sublingual films and tablets carry the same dental risk because both dissolve in your mouth with prolonged contact. Some patients find films easier to use and less likely to stick to their teeth, while others prefer tablets. There's no strong evidence that one is safer than the other for dental health.

The Suboxone film versus tablet choice usually comes down to personal preference, cost, and insurance coverage. If you're concerned about dental issues, the prevention strategies above matter far more than which formulation you use.

Injectable buprenorphine: If you're experiencing dental problems despite good oral hygiene, talk with your provider about Sublocade (a monthly injection) or Brixadi (weekly or monthly injection). These bypass the mouth entirely, eliminating the dental risk. Insurance coverage varies, but many plans cover injectables with prior authorization.

Buccal film: Belbuca is a buprenorphine film placed inside the cheek rather than under the tongue. It's primarily used for pain management, not opioid use disorder, but it also carries dental risks because it dissolves in the mouth. It's not a solution to the dental issue.

What if you've already developed dental problems?

First, don't panic—and definitely don't stop your Suboxone treatment. The benefits of staying in recovery far outweigh the dental risks, and most issues can be addressed with proper care.

Tell your provider: Tell both the dental clinician and buprenorphine prescriber about relevant medications and symptoms. They can decide whether the treatment plan needs review.

See a dentist promptly: Get a full dental exam to assess the extent of damage. Be honest about your buprenorphine treatment. Most dentists are familiar with the FDA safety communication and can provide targeted preventive care.

Consider treatment alternatives: If dental issues are severe or worsening despite good oral hygiene, discuss switching to an injectable form of buprenorphine. This isn't giving up on treatment—it's optimizing it to protect your overall health.

Focus on prevention going forward: Even if you've already experienced some decay or erosion, implementing the prevention strategies above can stop further damage. Many patients stabilize their dental health once they establish a consistent routine.

Remember that dental problems are treatable. They're not a sign that you should discontinue a medication that's keeping you stable and safe from opioid use. Work with your treatment team and dentist to find solutions that address both your recovery and your oral health.

Other Suboxone side effects to be aware of

Dental issues are one of several side effects some patients experience on buprenorphine. Most are manageable and improve over time as your body adjusts. Common issues during the first week on Suboxone include headaches, nausea, constipation, and fatigue.

If you experience sleep problems or interactions with other medications, including mental health medications or pain management drugs, talk with your provider. We can adjust dosing or timing to minimize side effects while maintaining effectiveness.

The key is staying in communication with your care team. We want you comfortable and stable on treatment—that's when recovery thrives.

The bottom line on Suboxone and dental health

Yes, sublingual buprenorphine can increase your risk of dental problems. But with simple, consistent oral hygiene practices—rinsing after dosing, waiting to brush, using fluoride products, and seeing a dentist regularly—you can protect your teeth while staying on life-saving medication.
