Even if you take good care of your teeth and don't have any obvious dental issues, it's still important to see a dentist regularly. Dentists can spot early signs of tooth decay and gum disease, and they can also detect other potential problems, such as oral cancer. In addition, regular cleanings can help to remove tartar and prevent tooth decay. So even if you're not experiencing any dental problems, it's still a good idea to schedule an appointment with your dentist every six months.
