Diabetes may cause tooth decay and weaken teeth.research may help to explain why people with both Type 1 and Type 2 diabetes are more likely to have tooth decay: lower durability and strength of dentin, the hard substance that underlies enamel and gives teeth structure.
“We’ve long seen elevated rates of cavity formation and tooth loss in patients with diabetes, and we’ve long known that treatments such as fillings do not last as long in such patients, but we did not know exactly why,” said Mohammad Ali Saghiri, an assistant professor of restorative dentistry at the Rutgers School of Dental Medicine.
