When a tooth dies, it means that the pulp inside the tooth, which contains nerves and blood vessels, has become infected or damaged to the point where it can no longer survive. This can happen due to various reasons, including severe decay, gum disease, or trauma, such as a tooth being knocked. A dead tooth can lead to pain, discolouration, and swelling if left untreated.

Preventative measures, such as wearing mouthguards during sports, avoiding biting on hard objects, and maintaining good dental hygiene, can help reduce the risk of tooth breakage. If a tooth is broken, cracked, or chipped, it's essential to seek dental care promptly to assess the damage and receive appropriate treatment.
