Tooth fracture – damage to the tooth with a violation of the integrity of its crown or root. Trauma to the teeth may be accompanied by the destruction of the tooth socket, fractures of the alveolar process or jaws.
- incomplete fractures (without opening the pulp):
- cracks in enamel and dentin;
- marginal fracture of the crown in the enamel zone;
- marginal fracture of the crown in the zone of enamel and dentin;
- complete fractures (with opening of the pulp) – open and closed:
- neck of the tooth;
- root tops.
The cause of a tooth fracture can be a blow, a fall, a sports injury, etc.
Severe pain, the intensity of which increases when you try to open your mouth; may be associated with signs of damage to the dental bed. When the enamel was broken off, complaints of mild pain from touch. With a fracture within the dentin, the pain is stronger. When the pulp is exposed, spontaneous pain increases sharply when the mouth is opened.
An x-ray examination is required.
When the pulp is exposed and there are signs of its inflammation, when it is not exposed, a vital extirpation is performed (conductive anesthesia). A root fracture requires its removal. In case of breakage of enamel and partly dentin – observation, and further cosmetic restoration of the crown.
