FDA Warns About Dental Problems with Buprenorphine Medicines Dissolved in the Mouth to Treat Opioid Use Disorder and Pain
What safety concern is FDA announcing?
The U.S. Food and Drug Administration (FDA) is warning that dental problems have been reported with medicines containing buprenorphine that are dissolved in the mouth. The dental problems, including tooth decay, cavities, oral infections, and loss of teeth, can be serious and have been reported even in patients with no history of dental issues. Despite these risks, buprenorphine is an important treatment option for opioid use disorder (OUD) and pain, and the benefits of these medicines clearly outweigh the risks.
Regular adherence to buprenorphine to treat OUD reduces withdrawal symptoms and the desire to use opioids, without causing the cycle of highs and lows associated with opioid misuse. The comprehensive approach of buprenorphine combined with counseling and other behavioral therapies is often one of the most effective ways to treat OUD. This approach, called medication-assisted treatment (MAT), is tailored to meet each patient’s needs and can help sustain recovery and prevent or reduce opioid overdose. According to the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA), MAT has been shown to be effective in improving patient survival, decreasing opioid use, and allowing patients to live a self-directed life, including the ability to gain and maintain employment.
What is FDA doing?
We are requiring a new warning about the risk of dental problems be added to the prescribing information and the patient Medication Guide for all buprenorphine-containing medicines dissolved in the mouth. The prescribing and patient information will also include strategies to maintain or improve oral health while undergoing treatment with these medicines. These strategies will include recommending that prescribers refer patients to dental care services and encourage them to have regular checkups while taking these products. Patients should tell the dentist about all medicines they take, including buprenorphine.
What is buprenorphine and how can it help me?
Buprenorphine was approved in 2002 as a tablet to be administered under the tongue to treat OUD. In 2015, buprenorphine was approved as a film to be placed inside the cheek to treat pain. There are also buprenorphine products for pain and OUD delivered by other routes such as a skin patch and injection, but FDA has not identified a concern for dental health related to these other forms. Buprenorphine works by changing the way the brain and nervous system respond to pain. At proper doses, buprenorphine also decreases the pleasurable effects of other opioids, making misuse of them less appealing. The benefits of buprenorphine medicines clearly outweigh the risks, particularly in the treatment of OUD.
The buprenorphine medicines that are associated with dental problems are tablets and films dissolved under the tongue or placed against the inside of the cheek. They are available as single-ingredient products and also in combination with naloxone. Buprenorphine medicines are marketed under the brand names Belbuca, Bunavail, Cassipa, Suboxone, Subutex, and Zubsolv. They are also available as generics.
What should patients and caregivers do?
Continue taking your buprenorphine medicine as prescribed; do not suddenly stop taking it without first talking to your health care professional as it could lead to serious consequences. Suddenly stopping these medicines could cause you to become sick with withdrawal symptoms because your body has become used to the buprenorphine medicine, or to relapse to opioid misuse that could result in overdose and death. For those suffering from addiction to opioids, the benefits of using buprenorphine medicines clearly outweigh the risks and should be considered in conjunction with counseling and other behavioral therapies. This comprehensive MAT approach is often one of the most effective ways to treat OUD, and can help sustain recovery and prevent or reduce opioid overdose.
Patients using buprenorphine medicines dissolved in the mouth should take extra steps to help lessen the risk of serious dental problems. After the medicine is completely dissolved, take a large sip of water, swish it gently around your teeth and gums, and swallow. You should wait at least 1 hour before brushing your teeth to avoid damage to your teeth and give your mouth a chance to return to its natural state.
Inform your health care professional if you have a history of tooth problems, including cavities. Schedule a dentist visit soon after starting this medicine and inform your dentist that you are taking buprenorphine, and schedule regular dental checkups while taking this medicine. Your dentist can customize a tooth decay prevention plan for you. Notify both your health care professional and your dentist immediately if you experience any problems with your teeth or gums.
What should health care professionals do?
Health care professionals should be aware the benefits of buprenorphine medicines clearly outweigh the risks and are an important tool to treat OUD. When combined with counseling and other behavioral therapies, this comprehensive MAT approach is often the most effective way for treating OUD, and can help sustain recovery and prevent or reduce opioid overdose.
Ask patients about their oral health history prior to prescribing treatment with a transmucosal buprenorphine medicine. These serious dental problems have been reported even in patients with no history of dental issues, so refer them to a dentist as soon as possible after starting transmucosal buprenorphine. Counsel patients about the potential for dental problems and the importance of taking extra steps after the medicine has completely dissolved, including to gently rinse their teeth and gums with water and then swallow. Patients should be advised to wait at least 1 hour before brushing their teeth. Dentists treating someone taking a transmucosal buprenorphine product should perform a baseline dental evaluation and caries risk assessment, establish a dental caries preventive plan, and encourage regular dental checkups.
What did FDA find?
Since buprenorphine was approved, we identified 305 cases of dental problems (131 cases classified as serious) with buprenorphine medicines dissolved in the mouth. These only include cases reported to FDA* or published in the medical literature,1,2 so there may be additional cases about which we are unaware. The average age of the patients was 42 years, but those as young as 18 years were also affected. Most cases were in patients using the medicines for OUD; however, 28 cases of dental problems occurred in patients using it to treat pain. In 26 cases, patients had no prior history of dental problems. Some cases reported dental problems occurring as soon as 2 weeks after treatment began, with the median time to diagnosis being approximately 2 years after starting treatment. Many cases were reported by health care professionals and provided documentation of extensive dental adverse events. Of the 305 cases, 113 mentioned two or more teeth were affected. The most common treatment for these dental problems was tooth extraction/removal, which was reported in 71 cases. Other cases reported requiring root canals, dental surgery, and other procedures such as crowns and implants.
*The cases were reported to the FDA Adverse Event Reporting System (FAERS) database.
What is my risk?
All medicines have side effects even when used correctly as prescribed, but in general the benefits of taking a medicine outweigh the risks. It is important to know that people respond differently to all medicines depending on their health, other medicines they are taking, the diseases they have, genetic factors, and many other reasons. As a result, we cannot determine how likely it is that someone will experience these side effects when taking buprenorphine medicines that dissolve in the mouth. However, the benefits of buprenorphine medicines for OUD and pain management clearly outweigh the risks. In particular, the comprehensive MAT approach of buprenorphine combined with counseling and other behavioral therapies is often one of the most effective ways to treat OUD, and can help sustain recovery and prevent or reduce opioid overdose.
How do I report side effects from buprenorphine?
To help FDA track safety issues with medicines, we urge patients and health care professionals to report side effects involving buprenorphine or other medicines to the FDA MedWatch program, using the information in the “Contact FDA” box at the bottom of the page.

Data Summary
A search of the FDA Adverse Event Reporting System (FAERS) database and the medical literature1,2 through December 31, 2018, identified 305 cases of dental adverse events reported with transmucosal buprenorphine use. Patients with opioid use disorder (OUD) may have a higher incidence of poor dental health;4 however, many cases described severe dental issues in patients with no reported prior history of dental problems (n=26). In addition, although most of the cases were in patients using transmucosal buprenorphine products for OUD, there was a subset of patients (n=28) who experienced severe dental adverse events while receiving pain-only indicated products (e.g., Belbuca) or stated the indication was for pain.
The average age of the patients in this case series was 41.8 years (range 18-71), and the median time to diagnosis was 24.25 months (range 0.5-182). Many cases reported a combination of dental decay, tooth loss, and tooth fractures in numerous teeth. Many cases were reported by health care professionals and provided documentation of extensive dental adverse events including “all upper,” “all lower,” “all,” “majority,” “most,” “multiple teeth,” and “rampant decay.” The cases often noted the number of teeth involved, with 113 cases mentioning two or more teeth. Some cases specifically mentioned involvement of 11 to 12 or more teeth, as well as all teeth in 11 cases. Of the 305 cases, 151 reported the treatment for the adverse event, with tooth extraction/removal as the most common, which was reported in 71 cases. Other treatments included root canal, dental surgery, and other restorative procedures such as crowns and implants.

Opioid Pain Relievers or Medicines to Treat Opioid Use Disorder - FDA Recommends Health Care Professionals Discuss Naloxone with All Patients when Prescribing
ISSUE: FDA is requiring drug manufacturers for all opioid pain relievers and medicines to treat opioid use disorder (OUD) to add new recommendations about naloxone to the prescribing information. This will help ensure that health care professionals discuss the availability of naloxone and assess each patient’s need for a naloxone prescription when opioid pain relievers or medicines to treat OUD are being prescribed or renewed. The patient Medication Guides will also be updated.
BACKGROUND: Opioid pain relievers are medicines that can help manage pain when other treatments and medicines are not able to provide enough pain relief. Certain opioids are also used to treat OUD. Opioids have serious risks, including misuse and abuse, addiction, overdose, and death. Naloxone can help reverse opioid overdose to prevent death.
The misuse and abuse of illicit and prescription opioids and the risks of addiction, overdose, and death are a public health crisis in the United States. As a result, FDA is committed to encouraging health care professionals to raise awareness of the availability of naloxone when they are prescribing and dispensing opioid pain relievers or medicines to treat OUD. FDA held discussions about naloxone availability with the Anesthetic and Analgesic Drug Products and the Drug Safety and Risk Management Advisory Committees, which recommended that all patients being prescribed opioids for use in the outpatient setting would benefit from a conversation with their health care professional about the availability of naloxone.
RECOMMENDATION:
Patients:
- Talk to your health care professionals about the benefits of naloxone and how to obtain it.
- Recognize the signs and symptoms of a possible opioid overdose. These include slowed, shallow, or difficult breathing, severe sleepiness, or not being able to respond or wake up. If you know or think someone is overdosing, give the person naloxone if you have access to it, and always call 911 or go to an emergency room right away. Naloxone is a temporary treatment, so repeat doses may be required. Even if you give naloxone, you still need to get emergency medical help right away.
- If you have naloxone, make sure to tell your caregivers, household members, and other close contacts that you have it, where it is stored, and how to properly use it in the event of an overdose. When using opioid medicines away from home, carry naloxone with you and let those you are with know you have it, where it is, and how to use it. Read the Patient Information leaflet or other educational material and Instructions for Use that comes with your naloxone because it explains important information, including how to use the medicine.
Health Care Professionals:
- Discuss the availability of naloxone with all patients when prescribing or renewing an opioid analgesic or medicine to treat OUD.
- Consider prescribing naloxone to patients prescribed medicines to treat OUD and patients prescribed opioid analgesics who are at increased risk of opioid overdose.
- Consider prescribing naloxone when a patient has household members, including children, or other close contacts at risk for accidental ingestion or opioid overdose.
- Additionally, even if the patients are not receiving a prescription for an opioid analgesic or medicine to treat OUD, consider prescribing naloxone to them if they are at increased risk of opioid overdose.
- Educate patients and caregivers on how to recognize respiratory depression and how to administer naloxone. Inform them about their options for obtaining naloxone as permitted by their individual state dispensing and prescribing requirements or guidelines for naloxone. Emphasize the importance of calling 911 or getting emergency medical help right away, even if naloxone is administered.
Patients and health care professionals are encouraged to report adverse events or side effects related to the use of these products to the FDA's MedWatch Safety Information and Adverse Event Reporting Program:
- Complete and submit the report online.
- Download form or call 1-800-332-1088 to request a reporting form, then complete and return to the address on the form, or submit by fax to 1-800-FDA-0178
