It is important to have regular dental check-ups every 6 months so your dentist can see if there are any changes to your oral health. This way, if there are any issues, they will be detected early on and it will be easier to address them. Plus, sometimes it is your dentist who may pick up on other medical issues you may have. For example, there is a strong correlation between periodontal disease and diabetes. Diabetes is a systemic disease, meaning that it can affect all major systems in your body--even your teeth. If your oral exam shows the beginnings of periodontal disease, you may want to visit your primary care provider for further assessment and diagnosis.
