Root Canal Treatment
When the nerve of a tooth becomes infected, root canal treatment can save the tooth. How do you know if you have an infected tooth? Some of the signs are heat and cold sensitivity, swelling and pain, or a bad taste in your mouth. Or, you may experience no symptoms at all and not realize that you have a dental problem.
Root canal treatment and subsequent tooth restoration usually involves three steps. First, your root canal dentist removes the infection to promote healing. Next, he places a post to strengthen the tooth. Finally, he crowns the tooth to protect it.
After root canal treatment, the tooth is weak and brittle. It is weak because the center of the tooth was removed to get at the infected nerve; only the sides of the tooth are left for support. And it is more brittle because the nerve and blood supply are gone.
This tooth was not crowned after root canal treatment. There is a tremendous amount of force on the edges of the teeth when they bite together, so it's likely that this tooth will break.
After a tooth breaks, it is much more difficult to repair. Dentist Volkan Kocakanat typically recommends a crown to cover and protect a root canaled tooth. The crown helps to prevent it from breaking.
