Signs you may need a root canal
The need for a root canal often announces itself through discomfort. Pay attention to:
- A toothache that is constant or starts on its own, even when you are not using the tooth
- Pain when you chew or put pressure on the tooth
- Sensitivity to hot or cold that lingers after the food or drink is gone, especially to heat
- Swollen or tender gums, sometimes with a pimple-like bump
- A chip or crack
- A tooth that looks gray or dark
- A tooth that feels looser than the others
A chip or crack lets bacteria in, which causes infection and inflammation. Swelling that comes and goes often points to an abscess, sometimes with a bad taste or smell. A severe toothache can also show up as a headache, and many people do not connect the two.
Other reasons a root canal becomes necessary
A deep cavity that reaches the root, a cracked tooth or problems under an old filling can all lead to a root canal. Because you may not feel anything at first, regular checkups every six months matter. Treatment may not reverse the damage already done, but it stops it from advancing and saves the tooth.
Why waiting is risky
A tooth that needs a root canal is in the process of dying, so we treat it as urgent. As the pulp dies, infection can spread to the surrounding tissue and bone. Left untreated, it can lead to an abscess, swelling of the jaw or face, fever and bone loss. Contact us promptly if you have severe pain when biting, heat sensitivity, a darkening tooth, swollen gums or a pimple on the gum.
When the tooth cannot be saved
A root canal works when there is enough natural tooth left to rebuild. If there is a root fracture, too little tooth structure, significant resorption or repeated past root canals, extraction may be the better choice. We can then discuss a crown, bridge or implant to replace it. Removing a hopeless tooth also keeps infection from spreading to nearby teeth, gums and bone.
If you have a toothache that does not settle, call us at (781) 289-3331. We can see you and find out what is going on.
Common questions
Do root canals hurt?
With local anesthesia, the procedure itself should not hurt. It feels similar to getting a deep filling. We may recommend medication afterward to help the area heal.
How long does a root canal take?
It varies. Many patients need one or two appointments of about 90 minutes each.
How does a root canal work?
We use X-rays to see the shape of the roots and where the infection is. Then we remove the infected pulp, clean the inside of the tooth and seal it so it is protected.
How much does a root canal cost?
It depends on the tooth, how severe the problem is and how much work is needed. Contact your insurance provider to understand your coverage.
How can I avoid needing a root canal?
Prevent cavities. Brush and floss every day, see your dentist regularly and limit foods and drinks that cause decay. A small cavity treated early rarely reaches the root.
