Teeth that protrude out tend to be more prone to injury. This is especially important for people who engage in contact sports, or people who are accident prone. Young children who may not be so aware about the dangers of their environment could slip, trip or fall on uneven terrain, and injure themselves.
A mouth guard should be worn when playing rugby, football, boxing and other martial arts. Proper protective gear should be worn to protect against the risks of falls and knocks that could result in teeth or jaw fracture. The mouth guard should be thick enough to absorb and dissipate the excessive forces that may land on the teeth and gums.
Severe tooth injury should be attended to promptly. Exposed tooth dentine or nerves of the pulp should be quickly cleaned and covered to prevent contamination and infection. Teeth that have been loosened by force may have to be splinted together to allow them to heal. Teeth that have been knocked out of the mouth can be replanted back into the jaw if immediate help from the dentist is obtained within 1-2 hours of injury. The longer the delay, the worse the prognosis for the tooth.
Biting on hard foods like nuts, candy or ice cubes may result in tooth fracture. If the fracture line is unfavourable and goes right through the centre of the tooth, it may not be possible to save the tooth. If only a corner of the tooth has broken off, the rough edges may be smoothed down, or a filling may be placed over it.
