After a root canal, One thing is very important to be answered is does the root canal treated tooth require a crown? Another question that usually immediately follows: Why are there many types of dental crowns available? Which type suits me? We will try to provide an answer to this question in this post.
A tooth is weakened after a root canal treatment and while aesthetics are a very important consideration when selecting your crown, function still tops the priority. Putting a crown over the tooth will not only give the tooth a natural look but will also be a kind of protective cover for the tooth that will enable its normal use.
Is crown necessary after root canal?
It usually happens that when a person’s pain from a root canal disappears, he/she assumes that the whole root canal procedure has been completed. But the truth is other way around,
After a root canal:
- Infection is extracted from the tooth.
- The tooth is treated and sealed.
- However, the structure of the tooth is weakened.
So, in most cases, we dentists advise getting a crown.
Without a crown, the tooth is highly prone to:
- Crack under chewing pressure
- Wear down faster
- Eventually fail
You might not notice it immediately, but over time, a cracked tooth after root canal is a very real risk.
When you might “NOT” need a crown?
Nonetheless, there are exceptional cases in which a crown may not be needed, including:
- Front teeth (as less pressure is applied when chewing)
- Little to no damage done to the tooth
In these situations, depending on your individual situation, your dentist will counsel you how to proceed. With this being said, the answer to your question is: the majority of time, a root canal procedure will require a dental crown.
