Tooth Crown Fracture
A tooth crown fracture refers to the break or crack in the visible, above-the-gum structure of a tooth, known as the crown. This type of dental injury can result from various causes, such as a strong impact to the mouth, chewing on hard objects, accidents, or even temporomandibular disorders (TMD).
TMD-related issues can contribute to a tooth crown fracture, as they are often associated with jaw misalignments. Common causes include unconscious teeth grinding (bruxism) or clenching, which are exacerbated by stress or jaw misalignments. These persistent, uneven pressure loads can weaken the enamel, leading to cracks or fractures, particularly in already compromised teeth.
Tooth crown fractures vary in severity, ranging from minor enamel cracks to deeper fractures affecting the dentin or even the tooth nerve. Symptoms of a tooth crown fracture include pain while chewing, increased sensitivity to heat and cold, and visible damage to the tooth surface.
Treatment depends on the extent of the fracture and may involve the use of filling materials, crowns, or veneers to restore the tooth’s shape and function. In severe cases, root canal treatments or tooth extraction may be necessary. Early dental examination is crucial to determine appropriate measures and prevent further complications. Additionally, for TMD-related cases, interdisciplinary treatment may be required, including dental care, physiotherapy, or the use of bite splints to relieve the jaw joints and prevent further damage.
