What a root canal actually does
A root canal removes inflamed or infected tissue inside a tooth, cleans the canal space, and seals it to prevent re-infection. Done well, the tooth stays in place and continues to function for years. The procedure has a reputation for being painful; in practice, the procedure relieves the pain people came in with.
When a root canal is the right call
Persistent tooth pain, sensitivity to hot or cold that lingers, swelling, or a tooth that hurts on biting may indicate that the pulp is involved. Sometimes the tooth has been silently dying for some time before symptoms arrive. An exam and x-ray help determine whether root canal therapy is the right path or whether other treatment makes more sense.
Common questions
Does a root canal always require a crown after?
Most back teeth benefit from a crown after root canal therapy because they are weakened and need protection. Front teeth sometimes can be restored with a more conservative restoration, depending on remaining structure.
Can I take antibiotics instead of having a root canal?
Antibiotics can manage an acute infection short-term, but they do not address the source. Without definitive treatment, the infection typically returns.
Is the procedure painful?
Local anesthesia keeps the procedure comfortable. Most patients describe the visit as easier than they expected and feel relief from the original pain afterward.
