Sore swollen gums around molar
Sore swelling around a molar can come from trapped food, gum inflammation, a erupting wisdom tooth, decay, or an abscess.
The short answer
Sore swelling around a molar can come from trapped food, gum inflammation, a erupting wisdom tooth, decay, or an abscess. Swelling around a molar is inflamed gingiva or tissue overlying the tooth. Trapped food, plaque, a partially erupted wisdom tooth, decay, a cracked tooth, or infection at the root can all produce soreness.
Why can a wisdom-tooth gum flap trap bacteria?
A flap over a partly erupted wisdom tooth is called an operculum and can trap bacteria. Pain on biting, temperature sensitivity, bad taste, pus, or facial swelling raises concern for a tooth or gum infection.
How can you clean a sore swollen area around a molar?
Rinse gently with warm salt water, brush the area carefully, and use an interdental cleaner if it can pass without force. Do not puncture the swelling or place caustic substances on it.
When does molar swelling need prompt dental treatment?
Seek prompt dental care if swelling lasts, recurs, produces pus, or limits chewing or opening the mouth. Fever, facial swelling, swallowing difficulty, or breathing difficulty requires urgent assessment.
Which treatment might the affected molar need?
Ask whether the molar needs cleaning, a filling, root canal treatment, wisdom-tooth management, or periodontal treatment. Ask whether an X-ray is needed to assess the roots and surrounding bone.
