Why Does It Take So Long to Brush Teeth After Root Canal Procedure?

The dentists suggest waiting for an hour or two after the procedure, before carrying on with regular brushing and teeth care. This is because the numbness medication (or anesthesia) takes this much time to wear off.

Wait for at least 1-2 hours after the procedure before you brush your teeth. Although root canal is a painless procedure, there is some tenderness in jaws and gums soon after the procedure. Chances are that the jaws might be sore as the mouth had been open for a longer time duration.

One more reason why one has to wait this long for brushing is the filling. The temporary filling in the teeth takes about an hour to set completely. You need to be careful that you don’t disturb the restoration during this time.

And one more question that arises is how long will the tooth last after this procedure. The answer is- for a lifetime. This depends mostly on the structure of the teeth. The biting force applied will also determine the life span of that tooth.

Talking about the side effects of this procedure, pain, swelling, and tooth fractures (in rare cases) are the probable side effects. If you have been experiencing pain for a longer time duration, visit your dentist sooner.
