What happens when a tooth breaks completely off?

When a tooth breaks completely off, it can expose the tooth's pulp and nerves, leading to pain, sensitivity, and an increased risk of infection. Immediate dental attention is crucial to assess the damage and determine if the tooth can be saved or if a crown or extraction is necessary. If a piece of the tooth is recoverable, a dentist may be able to reattach it. Proper care and treatment can help manage any complications and restore dental function.
