Crowns are used as a cover that can help restore structure and stability to a cracked, chipped or even partially broken tooth. The reason that any of these circumstances may occur to you will vary. However, the pain and sensitivity that you are likely to feel is common among many patients. That is why we work quickly to put a crown on your tooth, so that you can get back to normal activities without the annoyance of fractured teeth.
