There is also strong evidence of a bi-directional relationship between the severity of periodontal disease and type 1 and type 2 diabetes control: treatment of periodontal disease has been found to improve blood–sugar levels (Sanz et al, 2018).
Figures from NHS Digital (2020) indicate that dentist attendance among the general UK population is low, so many people with diabetes may be unaware that oral health is linked to control of their diabetes. Given the impact diabetes has on the population, it is important to use every opportunity to promote preventive health messages to the public. If health professionals – including nurses – are aware of these links, they can educate patients about the importance of maintaining good oral hygiene and visiting a dental professional, which can be done in a variety of settings.
