Broken or cracked teeth can occur as a result of decay, clenching/grinding, trauma, broken fillings or biting on hard foods.
It is very common that a broken tooth may not cause any pain, even so, they should be treated as urgent and seen by a dentist as soon as possible. A broken tooth can act as a direct road for decay and infection to enter straight into the nerve of the tooth. If treated within a reasonable timeframe, the dentist may be able to place a filling, crown or root canal treat the tooth. In severe cases, the tooth may need to be removed.
