Key Takeaways
  1. Rotten teeth are an advanced form of tooth decay that occurs when a cavity or cavities reach the pulp at the center of the tooth, requiring fillings, a root canal, or, in some cases, full removal of the infected tooth.
  2. Once tooth decay has reached the stage of rotten teeth, it can only be treated by a dentist. So, if you notice a dark spot or spots on the surface of your teeth or develop pain or sensitivity in your teeth or gums that lasts more than a few days, see a dentist right away.
  3. Avoid rotten teeth by practicing good oral hygiene (regularly brushing with a stannous fluoride-containing toothpaste, flossing, and rinsing with mouthwash) and by visiting your dentist at least twice a year for a cleaning and checkup.
