Cracked teeth causes and treatment
A cracked tooth may cause brief biting pain or sensitivity; treatment depends on crack depth, tooth structure, and pulp involvement.
The short answer
A cracked tooth is a fracture through enamel and possibly dentin or the pulp, and it needs examination because the crack’s direction and depth determine whether the tooth can be restored.
What can cause cracks to develop in your teeth?
Cracks can result from biting hard objects, repeated chewing forces, large fillings, grinding, trauma, or temperature stress. A crack may flex under pressure, irritate the pulp, allow bacteria toward the nerve, or extend below the gumline where restoration is difficult.
How can you protect a cracked tooth before treatment?
Chew on the opposite side, avoid hard foods, and do not test the tooth repeatedly by biting. The dentist may use illumination, magnification, bite testing, pulp tests, probing, and selected radiographs; treatment can range from a bonded restoration or crown to root canal treatment with a crown, or removal when the fracture cannot be stabilized.
When should a cracked tooth be examined by a dentist?
Seek prompt care for sharp biting pain, lingering hot or cold sensitivity, a loose fragment, swelling, or a crack visible in a tooth. Facial swelling, fever, or difficulty swallowing requires urgent attention.
What should you ask about treating a cracked tooth?
Ask where the crack extends, whether the pulp and root are involved, whether the tooth can be predictably restored, and what protection is needed while deciding.
Frequently asked questions
Can a cracked tooth heal itself?
Tooth structure does not fuse across a crack; symptoms may fluctuate while the fracture remains.
Why does it hurt when I release my bite?
A flexing crack can move a cusp or irritate the periodontal ligament as pressure is released.
