Blog Summary: Learn what to expect from a root canal—from costs and recovery to eating after treatment—and how it helps save your natural tooth and stop infection.
What Is a Root Canal?
A root canal is a dental procedure that involves removing and replacing the pulp in your tooth. Pulp is soft tissue that is found inside your tooth. The role that the pulp plays is to provide nourishment for your tooth – it helps keep your tooth alive. The pulp can get exposed to infection if you have deep decay or an injured tooth. Infection in the pulp can lead to an abscess in or around the tooth as well as swelling and pain.
What Is the Purpose of a Root Canal?
How Do I Know if I Need a Root Canal?
You cannot determine on your own if you need a root canal. If you are having trouble with one of your teeth – pain, swelling, injury – talk to a dentist about your symptoms. The dentist will examine your tooth, gums, and the area surrounding your gums to assess the tooth’s condition. In some cases, imaging is also necessary to get a clear idea of the condition of your tooth. They will let you know if you need a root canal or may recommend that you see a dentist with specialized training in the procedure.
What Type of Dentist Does Root Canals?
The type of dentist that does root canals is called an endodontist. An endodontist specializes in dealing with issues related to dental pulp. Some general dentists offer root canal services for cases that are straightforward. Choosing to have an endodontist do your root canal will give you the most specialized care and the best chances for getting a repair that is long-lasting.
Root Canal Cost
You will pay less out of pocket for a root canal if you have dental insurance or some type of dental financing plan. The exact amount depends on the factors outlined above as well as the details of your insurance. If you do not currently have insurance, or are unhappy with your current plan, you can explore the financing and insurance options available through the Smile Generation. You can also check with your dentist about payment options if you cannot cover the cost of the root canal upfront.
