Enamel-dentine fracture is a complete fracture of the tooth enamel and dentine without the exposure of the pulp. Pulp sensibility testing is recommended to confirm pulpal health. Treatment depends on how close the fracture is in relation to the pulp.
A tooth that has experienced trauma may become loose due to the periodontal ligament becoming damaged or fracture to the root of the tooth. Splinting ensures that the tooth is held in the correct position within the socket, ensuring that no further trauma occurs to enable healing. [ 37 ]
An enamel fracture occurs when the outer layer of the tooth, known as enamel, is fractured without directly impacting the underlying tooth tissues of the dentine or pulp. [1] This phenomenon typically arises from hard, external forces impacting the tooth to induce enamel breakage. [ 1 ]
Chewing ice can create tiny cracks in the tooth enamel, which may spread and lead to tooth fractures. It can also chip or break vulnerable teeth — and really, why go to the dentist more than you ...
More than 75% of tooth fractures occur in the upper jaw, with the majority affecting the anterior teeth—particularly the central incisors, followed by the lateral incisors and canines. This trend highlights the vulnerability of these teeth to trauma, often resulting in enamel infractions or more extensive fractures. [15]
Another consideration is unsupported tooth structure. When preparing the tooth to receive a restoration, unsupported enamel is removed to allow for a more predictable restoration. While enamel is the hardest substance in the human body, it is particularly brittle, and unsupported enamel fractures easily.

A fracture of a tooth can involve the enamel, dentin, and/or pulp, and can be orientated horizontally or vertically. [10]: 24–25 Fractured or cracked teeth can cause pain via several mechanisms, including dentin hypersensitivity, pulpitis (reversible or irreversible), or periodontal pain. Accordingly, there is no single test or combination of ...
