A root canal is a procedure that removes an infected or dying nerve when bacteria manage to get inside the tooth. It does not remove the roots of your tooth, which is a common misconception.
If you have throbbing pain that aches all the time, then your tooth will most likely need a root canal. Typically the bacteria will burrow its way through the hard structure of your tooth to reach the soft, inner pulp that houses the nerve. Think about mice biting through your cardboard cookie box so that they can eat the cookies inside.
Luckily for you, we can perform most root canals and get you out of pain very quickly. Most of all, it is relatively painless, and the earlier you are treated, the less discomfort you will feel after treatment.
