Cavities. We've all had them or worry that our dentist might discover new ones with every check-up. While tooth decay isn't very fun to deal with, it can be helpful to understand what types of cavities there are and how to prevent them. When you're informed about the different types of tooth decay, you can communicate more effectively with your dentist and feel better about your oral health journey.
Believe it or not, according to the National Institute of Dental and Craniofacial Research (NIDCR), 92% of American adults aged 20 to 64 have had tooth decay in their permanent teeth, and 26% currently have untreated dental decay. That said, not all cavities are the same, and dental professionals use a specific cavity classification system to assess them. There are six classes of cavities based on tooth type and the location of the decay, and four classifications that describe the severity of the decay.
