Suboxone and Tooth Decay: Dr. Isherwood’s Prevention Tips

March 13, 2025

 Suboxone has become a crucial medication in Medication-Assisted Treatment (MAT) for opioid addiction recovery, but many patients express concerns about tooth decay. Is Suboxone itself the culprit, or is there more to the story? 

Dr. Isherwood, a trusted expert, explains that the issue primarily arises from how Suboxone interacts with oral health, not from the medication alone. In response, the FDA released guidelines in 2022 to help patients minimize dental risks associated with Suboxone use. 

Why Does Suboxone Affect Dental Health? 

Sublingual Absorption and Saliva Reduction 

Suboxone dissolves under the tongue, facilitating rapid absorption. However, this method reduces saliva production, causing dry mouth (xerostomia), a known risk factor for cavities. 

Increased Acidic Exposure 

The medication’s acidic nature can weaken tooth enamel, increasing vulnerability to decay and sensitivity. The FDA acknowledges this and provides preventive strategies to combat these effects.

Dr. Isherwood’s Step-by-Step Guide: Protecting Your Teeth While Taking Suboxone 

Step 1: Wait Before Taking Your Dose 

Avoid food, drinks, or tobacco for at least 15 minutes before taking Suboxone. These substances can alter absorption and increase mouth acidity. 

Tip: Drink plain water if needed, then wait the recommended time. 

Step 2: Proper Placement of Suboxone 

Place the medication under your tongue and tuck your chin to your chest so you are looking to the ground near your feet. This posture helps the medication stay in place, dissolve correctly, and encourages saliva retention in the mouth. 

Step 3: Dissolve Completely and Spit Out 

Do not swallow the dissolved medication. Buprenorphine absorbs effectively through oral tissues, not the stomach. Swallowing can prolong acidic exposure, increasing tooth decay risks. 

Step 4: Rinse According to FDA Guidelines 

After spitting out the completely dissolved Suboxone, rinse your mouth thoroughly with water. Swish gently around teeth and gums, then spit or swallow. This removes residual acidity, significantly reducing enamel damage risks. 

Additional Tips for Optimal Oral Health while on Suboxone

Stay Hydrated to Combat Dry Mouth 

  • Drink water frequently. 
  • Chew sugar-free gum or use xylitol lozenges to stimulate saliva production. 

Use Fluoride-Enhanced Products 

  • Fluoride toothpaste strengthens enamel. 
  • Opt for alcohol-free fluoride mouthwash to prevent dry mouth. 

Avoid Sugary and Acidic Drinks 

  • Minimize soda, energy drinks, and acidic juices. 
  • Choose water, herbal tea, or milk instead. 

Regular Dental Visits 

  • Schedule dental checkups at least twice yearly. 
  • Inform your dentist of your Suboxone treatment for tailored care. 

Debunking Common Myths About Suboxone and Tooth Decay 

  • Myth: “Suboxone automatically ruins teeth.” 
  • Truth: Problems stem from saliva reduction and oral pH changes, not directly from the medication. 
  • Myth: “Brush immediately after taking Suboxone to prevent cavities.” 
  • Truth: Brushing immediately can spread acidic residue. Rinse first, then wait 1 hour before brushing according to FDA guidelines. 
  • Myth: “Taking Suboxone guarantees tooth loss.” 
  • Truth: Good dental care and adherence to expert guidelines significantly reduce dental risks.
