What is a root canal?

A root canal is a routine dental procedure that cleans out infection from the inside of your tooth. When the nerve becomes infected or irritated, usually from decay, a deep crack, or an old filling, the tooth becomes painful. A root canal removes the infection, keeps the tooth in place, and helps you avoid more serious problems later.

Signs you may need a root canal

If you’re unsure, call us — we can take an X-ray and let you know exactly what’s going on.

Common Causes

Once bacteria reach the nerve, the tooth becomes infected and painful. A root canal removes the infection while letting you keep your natural tooth.

What happens during the visit

Why the crown matters

After a root canal, the tooth becomes more fragile. A crown helps protect it, restores strength, and keeps the tooth working normally. Without a crown, the tooth can crack later — so it’s an important step.

Why a root canal is a good option

Does it hurt?

Most people are surprised at how easy the procedure feels. With modern numbing, a root canal is usually no more uncomfortable than getting a filling. Afterward, you may feel a little sore for a day or two — that’s normal and usually mild.

Aftercare

We’ll give you personalized instructions before you leave.

Cost, insurance, and payments

Most insurance plans cover part of the cost for root canals and crowns. We’ll check your benefits, give you a written estimate, and walk you through monthly payment options if you need them.
We accept CareCredit, Cherry, Sunbit, LendingTree, and other financing choices.
