Swelling in molar teeth
Swelling around a molar usually signals inflamed gum tissue, a cavity with pulp infection, a dental abscess, or inflammation around a partially erupted.
The short answer
Swelling around a molar usually signals inflamed gum tissue, a cavity with pulp infection, a dental abscess, or inflammation around a partially erupted wisdom tooth, so the cause needs examination.
What can cause swelling around a molar tooth?
A molar has a crown, roots, pulp containing nerves and blood vessels, and surrounding periodontal tissues. Swelling may be located in the gum, beside the root, or in the cheek as infection spreads through nearby tissue.
Which parts of a molar may be involved?
A molar has a crown, roots, pulp containing nerves and blood vessels, and surrounding periodontal tissues. Swelling may be located in the gum, beside the root, or in the cheek as infection spreads through nearby tissue.
Common triggers include trapped food and gum infection, deep decay, a cracked tooth, failed root-canal treatment, or pericoronitis around a wisdom tooth.
What can you do now for swelling around a molar?
Rinse gently with warm salt water, keep the area clean with a soft brush, drink fluids, and use a cool compress outside the cheek. Do not pierce the swelling or place aspirin, alcohol, or concentrated oils on the gum.
A dentist may examine the tooth, test pulp response, gently assess the gum, and take a dental radiograph. Treatment can include drainage, a filling, root-canal treatment, gum care, or extraction depending on the source.
When does molar swelling need urgent dental care?
Seek urgent dental care for swelling with tooth pain, pus, bad taste, fever, or difficulty opening the mouth.
Go to emergency care immediately if swelling reaches the eye or neck, or if breathing, swallowing, or speaking becomes difficult.
Where exactly is the swelling around the molar?
Is the swelling beside the gum, at the root, or around a wisdom tooth?
Do I need drainage, a filling, root-canal treatment, gum treatment, or removal?
Frequently asked questions
Can a swollen molar heal without treatment?
A rinse may ease irritation, but swelling from an abscess or pulp infection generally needs dental treatment.
Should I apply heat?
Use a cool compress outside the cheek; heat can increase discomfort and is not a treatment for dental infection.
