How can drug use affect oral health?

Drug use can have serious consequences for oral health through a number of mechanisms. Many drugs, such as cocaine, methamphetamine and cannabis, reduce saliva production. A dry mouth (xerostomia) increases the risk of tooth decay and gum inflammation. Stimulants can also cause teeth grinding, which leads to tooth wear. Cannabis use can reduce blood flow to the gums, making inflammation more common. When the balance of the oral flora is disturbed, harmful bacteria gain the upper hand, which can worsen gingivitis or periodontitis. Dental care is often neglected during prolonged drug use, which makes the problems worse. Regular check-ups and professional cleaning are essential to limit the damage as much as possible. Stopping drug use improves saliva production and reduces the strain on the gums. The periodontist can offer guidance on restoring oral health after drug use.
