Why Is a Dental Crown Needed After a Root Canal?
A root canal treatment can save a tooth that has become infected, severely decayed, or damaged. However, after a root canal, the tooth may be more vulnerable to cracking or breaking. For this reason, a dental crown is often recommended after root canal treatment, especially for molars and premolars.
During a root canal procedure, infected tissue is removed from inside the tooth. In many cases, the tooth has also already lost a significant amount of healthy structure because of decay, fractures, or previous fillings. A dental crown covers the remaining tooth and helps protect it from the forces of everyday chewing.
Benefits of a Crown After Root Canal Treatment
A crown can help:
Protect the tooth from fracture
Restore strength and chewing function
Cover and protect weakened tooth structure
Improve the appearance of a damaged or discoloured tooth
Help the treated tooth remain functional for many years
Not every root canal-treated tooth requires a crown. Front teeth with enough healthy structure may sometimes be restored with a filling or another type of restoration. Your dentist will recommend the best option based on the location of the tooth, how much tooth structure remains, and your bite.
If you have recently had a root canal in Woodbridge, Vaughan, or the surrounding area, speak with your dentist about whether a crown is recommended to protect your tooth and maintain your smile.
