Cracked teeth are very common and just about every person will have at least one in their lifetime. Symptoms usually involve pain when biting, like a jolt through the tooth. Over time a cracked tooth will develop hypersensitivity to hot and cold substances.
When you come to us with what you think is a cracked tooth, we will confirm the diagnosis by attempting to reproduce the symptoms. We will have you bite down on a special stick, and if it triggers pain in a specific spot on the tooth, then we will have found the source of the problem. Sometimes these cracks are actually visible with a bit of staining, as demonstrated in the photo to the right.
Other times a crack might be internal and not immediately visible. In the second photo on the right, this patient had a post in his tooth and a crown over top. The tooth cracked, triggering various symptoms, but the problem was only clearly evident when the post and crown were removed.
