Does Aspirin Cause Tooth Erosion?

In the clinical case study, the top surface of the teeth, also called the occlusal surface, showed severe erosion of the lower molars and premolars and on the lower anterior teeth on the tongue side. The researchers concluded that the aspirin powder caused the tooth erosion.2

Another study examined 42 children with rheumatoid arthritis. The participants were split into two groups, those who chewed aspirin, and those who swallowed it. The study found that the 25 children who chewed aspirin tablets experienced severe erosion of the upper and lower primary molars, and their first permanent molars. The 17 children who swallowed the aspirin tablets experienced no erosion of their teeth. The scientists concluded that the tooth erosion these children developed was due to chewing the aspirin tablets.3

These studies show that aspirin can affect the structure of the tooth surface depending how the analgesic is taken and can cause irritation to the soft tissue in the mouth. Consult with your dentist and physician if required doses of aspirin are recommended for a medical condition.
