• Adults 20 or older with diabetes are 40% more likely to have untreated cavities than similar adults without diabetes.1
  • There is an association between having diabetes and periodontal (gum) disease, a leading cause of tooth loss.2,3,4
  • About 60% of US adults with diabetes had a medical visit in the past year, but no dental visit.1
  • Expanding health care coverage for periodontal treatment among people with diabetes could save each person about $6,000 (2019 US dollars) over their lives.5
  • Adults 50 or older with diabetes lack functional dentition (have fewer than 20 teeth) 46% more often and have severe tooth loss (8 or fewer teeth) 56% more often than adults without diabetes.6
  • Adults 50 or older with diabetes are more likely to report that they have a hard time eating because of dental problems.7
  • Annual dental expenditures for an adult with diabetes are $77 (2017 US dollars) higher than for an adult without diabetes. This cost translates to $1.9 billion for the nation.8
  • Treating periodontal disease significantly improves blood sugar level (glycemic control) among people with diabetes compared to no treatment or routine care.9
