Cracked teeth are very common and just about every person will have at least one in their lifetime. Symptoms usually involve pain when biting, similar to a jolt of lighting through the tooth. Over time the tooth develops hypersensitivity to hot and cold substances. These symptoms are often what bring a patient in to the office.
Once in the office, we will try to reproduce the symptoms and confirm a cracked tooth by having the patient bite down on a special stick. If it triggers pain, in a specific spot on a tooth, but not the entire tooth, then we have found the source of the problem. Sometimes these cracks are visible with a bit of staining as demonstrated in the photo to the right.
Other times the crack is more internal and not visible at first. With the second photo on the right, the patient had a post in the tooth and a crown over top. The tooth cracked, triggering various symptoms, and was only clearly evident with the post and crown removed.
