Suboxone Tooth Decay Lawsuit

Suboxone is a medication for people who are battling opioid addictions. It helps by stopping the desire to use drugs while taking the medicine. However, there has recently been an alarming rise in people who have suffered from tooth decay and dental problems after using Suboxone sublingual films or tablets.

What Is Suboxone?

Suboxone is a medicine prescribed to people who have opioid dependencies. It helps stabilize people during detox and supports recovery from opioid use disorder. It’s a combination of two drugs: buprenorphine, which is a partial opioid agonist, and naloxone, an opioid antagonist. It is prescribed as a dissolvable film that patients use under the tongue or on the cheek.


Buprenorphine is a partial opioid agonist— an opioid medication that mimics mild opioid effects. This means that buprenorphine alleviates withdrawal symptoms and cravings without eliciting the complete effects seen with other opioids (like heroin, fentanyl, oxycodone, hydrocodone, etc.), facilitating a smoother transition away from the patient’s preferred opioid substance. Additionally, it can hinder other opioids from attaching to and activating the patient’s opioid receptors, serving as a deterrent against the misuse of alternative opioids.


Naloxone is an opioid antagonist medication or “blocker.” It only works in the body if the patient injects the tablet or film instead of dissolving it in the mouth as prescribed. If naloxone is injected, it causes uncomfortable withdrawal symptoms in people dependent on opioids. This, therefore, discourages those reliant on intravenous (IV) opioids from injecting buprenorphine/naloxone and helps them stay on track in their opioid recovery process.

How Does Suboxone Cause Tooth Decay and Dental Problems?

Suboxone is dissolved in the mouth, under the tongue, or against the cheek. Patients typically take Suboxone between 1 to 3 times daily, exposing their teeth multiple times throughout the day to the medication. Some reasons why Suboxone causes tooth decay and other dental problems include but are not limited to:


When Suboxone dissolves, it becomes acidic, with a pH of 3.4 in water. This acidity can wear down enamel, making teeth prone to bacteria and decay.


Suboxone users often have lower saliva levels. Less saliva to protect teeth increases the risk of decay, as food remains in place, providing a breeding ground for bacteria.

What Dental Problems Does Suboxone Cause?

According to the National Library of Medicine, the active drug in Suboxone, buprenorphine, can cause:

Severe Tooth Decay

Suboxone users have found this to be the biggest issue, leading to numerous cavities and harm to teeth, frequently causing emotional distress.

Tooth Erosion

The use of Suboxone could potentially wear away tooth enamel, increasing the risk of decay and sensitivity and other dental problems, including:

Dry Mouth

Dry mouth, a potential side effect of Suboxone, reduces saliva production, which, in turn, diminishes the protective effect of saliva on teeth, increasing the risk of dental problems such as decay caused by harmful bacteria and substances.

Gum Problems

Suboxone use may contribute to gum problems, including inflammation and periodontal disease, significantly affecting overall dental health.

Tooth Fractures

The overall poor oral hygiene caused by the use of Suboxone sublingually can lead to tooth fractures and broken teeth.


Several of the mentioned dental issues carry the potential to result in infections, which, aside from being painful and expensive, can also have the risk of spreading, posing serious threats, especially for individuals who have an impaired immune system or are elderly.

Suboxone Studies Regarding Tooth Decay Concerns

Multiple studies suggest concern as there is a significant link between dental issues and using sublingual buprenorphine. These Suboxone studies have formed the foundation for Suboxone tooth decay lawsuits and support many plaintiffs’ claims.

2013 Suboxone Study of Buprenorphine Users

study in 2013 at Brigham and Women’s Hospital in Boston looked at patients getting treatment for opioid dependence. It found that those using buprenorphine had tooth decay and dental issues. More than 90% of the patients in the study had lower saliva protection for their teeth. This connection suggests that using buprenorphine might be linked to a higher risk of tooth problems.

Journal of the American Medical Association (JAMA) Suboxone Study

In December 2022, a study in the medical journal JAMA revealed that patients using the sublingual film form of Suboxone were more prone to dental issues than other forms of buprenorphine or naloxone. While researchers are still exploring the reasons behind this tooth decay, it may be related to Suboxone’s impact on saliva production. Saliva plays a crucial role in maintaining clean teeth and reducing acidity in the mouth. If Suboxone interferes with saliva production, it could increase acidity and bacteria levels, making dental problems more likely to occur.

2023 Study of Suboxone Adverse Events Reported to the FAERS

In 2023, a study examined adverse event reports submitted to the United States Food and Drug Administration Adverse Event Reporting System (FAERS) from 2015 to 2022. The findings from the data revealed that sublingual Suboxone had a significantly higher occurrence of adverse events related to dental disorders compared to buprenorphine administered orally.

Suboxone Manufacturer Negligence

People filing Suboxone tooth decay lawsuits have identified Indivior, Inc. and Aquestive Therapeutics Inc. as the leading companies they’re taking legal action against. Aquestive Therapeutics focuses on making medicines for unmet medical needs, like nausea pills for chemotherapy patients, and Indivior specializes in Buprenorphine-based drugs for treating opioid addiction. Both companies played a role in creating the sublingual film version of Suboxone, but Indivior is the leading medication producer.

Failure To Warn of Suboxone Risks

The manufacturers of Suboxone, Indivior, and Aquestive Therapeutics are legally obligated to provide accurate warning labels for patients and providers to make informed decisions. Plaintiffs claim that these manufacturers knew or should have known that sublingual use of Suboxone could raise the risk of tooth decay or dental complications, given their expertise in similar drugs and reports of dental problems, but they failed to warn users. If Suboxone users can prove negligence in this regard, causing their dental injuries, it could result in Indivior and Aquestive Therapeutics being held accountable in product liability lawsuits.

Suboxone and Tooth Decay Lawsuits

Lawsuits against Suboxone claim that the manufacturers of the drug, Indivior, and Aquestive Therapeutics, neglected to adequately caution its users about potential dental issues, such as tooth decay, oral infections, cavities, and tooth loss associated with the use of Suboxone. In recent months, over 100 lawsuits have been filed by people impacted by the use of Suboxone, and more lawsuits will likely emerge as more people learn about the connection between Suboxone, tooth decay, and other dental complications.
