How should cracked teeth be treated?

Varies: It all depends on the extent of the fracture. Some teeth can be restored with a simple restoration, others will need root canal therapy and a crown. Some vertically fractured teeth are hopeless and require extraction. This tooth cannot be evaluated over the internet... You need to call a local dentist for an appointment.

Cracked Teeth: can cause Cracked Tooth Syndrome (when pressure is applied) if the proximity of the crack already approached the nerve.
