Drug use can have a negative impact on dental health as well as overall health. Patterns of oral health pathology attributed to methamphetamine users, for example, include rampant tooth decay, accelerated tooth wear, unexplained advanced gum disease, missing multiple teeth, and overall detrimental dental effects that are rapid and severe. These patients also often seek cosmetic dental treatment, such as veneers and whitening, which give dentists another opportunity to discuss suspected substance misuse, provide referrals for treatment, and encourage cessation of drug misuse.
