Inflamed molar

An inflamed molar may have irritated gum, decay, a crack, pulp inflammation or infection around the root, so the cause must be identified before treatment.

A molar has a broad chewing surface and multiple roots. Swelling beside it can come from plaque, a partially erupted wisdom tooth, or infection inside the tooth or surrounding bone.

Keep the area clean, avoid chewing on it and use only suitable pain relief as directed. The dentist may test the pulp, examine the gums, tap the tooth and take an X-ray.

Seek prompt care for persistent pain, swelling, pain on biting, bad taste or lingering sensitivity. Get urgent help for swelling near the eye or neck or swallowing difficulty.

Ask whether the pulp is inflamed, whether the tooth is cracked, what the X-ray shows, and whether filling, root canal treatment or extraction is needed.
