Oral health effects

  • Xerostomia and rampant caries

    Opioids (including methadone maintenance) reduce salivary flow; combined with sugar cravings, sugar-containing methadone syrup, and neglected hygiene, caries rates are high and often cervical/smooth-surface.

    Mechanism: Opioid-induced reduction in salivary secretion plus frequent high-sugar intake and poor plaque control.

    Clinical management: High-fluoride toothpaste, fluoride varnish, saliva substitutes, dietary counseling, and short recall intervals; ask whether the methadone formulation is sugar-free.

  • Dental problems with transmucosal buprenorphine

    Sublingual/buccal buprenorphine products have been associated with tooth decay, fractures, infections, and tooth loss; the FDA added a dental warning in 2022.

    Mechanism: The acidic film/tablet dissolves against the teeth, lowering oral pH and contributing to demineralization.

    Clinical management: Advise patients to swallow a mouthful of water after the dose dissolves and wait at least 1 hour before brushing; provide fluoride and early dental follow-up. Do not advise stopping buprenorphine.

  • Periodontal disease and tooth loss

    People with opioid and other substance use disorders have more severe periodontal disease and tooth loss than the general population, and are less likely to have received dental care.

    Clinical management: Periodontal therapy, oral hygiene instruction, and flexible, non-judgmental scheduling to support attendance.
