Can a root canal-treated tooth still get decay?
A root canal-treated tooth can certainly still get decay. It is important to brush and floss around the tooth as usual and have a regular check-up with your dentist to check for problems. Even with a crown over the top of the tooth, decay can still affect the tooth underneath. Remember that a root canal-treated tooth has no nerve and so will not cause any pain even if it becomes heavily decayed. You may not be aware of any problem until it is too late.
