Teeth that are afflicted with periodontal disease, severe decay, and those that are impacted are all candidates for removal. Otherwise, most teeth can either receive treatment — such as root canals or gum disease treatment — or be fitted for a crown. Removal is a last-resort procedure for severely compromised and unhealthy teeth. If you have a tooth (or teeth) that you believe need to be removed, it is important to schedule an appointment with your dentist as soon as possible.
