A fall or a more or less violent impact involving contact between the tooth and an external element can cause partial or total loss of the crown.
It is also possible for a tooth to break in the event of :
- intense grinding due to repeated friction of the enamel ;
- intense and violent clenching which, under the force of the jaw muscles, breaks the tooth (known as clenching);
- the tooth is not properly embedded in the opposite jaw, leading to repeated shocks that eventually break the tooth.
