Root Canal Therapy
Modern root canal treatment is designed to relieve pain and help save natural teeth.
Care designed around your smile, comfort, and long-term health.
Root canals have gotten a terrible reputation over the years. The treatment that was once associated with pain has become much gentler and more predictable with technological advancements. It is usually the least traumatic and most conservative way to treat infected teeth or irreversible nerve pain.
During a root canal, the nerve and any underlying infection is removed from the tooth. While there may be some post-operative soreness, the nerve pain that most patients come in with resolves almost immediately after treatment.
What to know
When a root canal may be needed
Deep decay, cracks, trauma, or infection can damage the nerve inside a tooth and create lingering pain or swelling.
Saving the natural tooth
When predictable, root canal therapy can preserve the tooth instead of removing it.
Restoring the tooth afterward
Many root canal-treated back teeth need a crown afterward to protect the remaining structure from fracture.
Root Canal Therapy FAQs
What is root canal therapy?
Root canal therapy treats infection or inflammation inside a tooth by removing damaged pulp tissue, cleaning and sealing the canal space, and restoring the tooth so it can continue functioning.
How do I know if I might need a root canal?
Signs can include lingering tooth pain, sensitivity to hot or cold, swelling, tenderness when biting, discoloration, or a pimple-like bump on the gums. An exam and X-rays are needed to confirm the diagnosis.
Is a root canal painful?
Root canal therapy is performed with local anesthesia, and the goal is to relieve pain caused by infection or inflammation. Many patients feel much better after the source of infection is treated.
Will I need a crown after a root canal?
Many back teeth need a crown after root canal therapy because the remaining tooth structure can be weaker and more prone to fracture. Your dentist will explain what restoration is recommended.
Is it better to save the tooth or remove it?
When predictable, saving a natural tooth can preserve chewing function and avoid the need for replacement. Sometimes extraction is the better option, depending on the crack, decay, bone support, or restorability of the tooth.
