A tooth fracture is caused when there is any accident, improper biting forces, sudden trauma due to biting hard substances. Types of fractures include break, cracked lines, split tooth, vertical root fracture, etc. Since our teeth cannot heal on their own, repairs and treatments have to be done to retain the form and function of the teeth.  Treatment options depend on the extent of the fracture. If it involves only enamel then simple Tooth colour filling or veneers may help. When it is too deep to involve the centre of the tooth, then it requires root canal treatment followed by a cap or veneer. If it is a through and through fracture then it needed to be extracted and replaced by an tooth implant.
