North Andover Cosmetic Dentist

Modern cosmetic dentistry techniques make it easier than ever for you to have a bright, even smile. A dental checkup can benefit more than just your teeth! Dentists can spot a variety of other health problems just by looking into your mouth. Regular dental checkups are an important part of preventive health care.

Here’s a look at some of the things your dentist may be able to tell from a routine exam:

  • Signs of Tooth Decay: Your dentist will look for signs of tooth decay, such as cavities or white spots on your teeth.
  • Gum Disease: Your dentist will check for signs of gum disease, such as red, swollen, or bleeding gums.
  • Oral Cancer: Your dentist will look for signs of oral cancer, such as sores in your mouth that don’t heal.

Dental checkups are important because they allow your dentist to spot problems early, when they’re easier to treat. So be sure to schedule regular checkups with your dentist!
