Back molar swollen gum
A swollen gum around a back molar may result from trapped food, gum inflammation, decay, infection, or a partially erupted wisdom tooth.
What can cause swelling around a back molar?
A swollen gum around a back molar may result from trapped food, gum inflammation, decay, infection, or a partially erupted wisdom tooth.
What does swelling around a back molar indicate?
Swelling behind or around a back molar is inflammation, not a diagnosis. A gum flap, cavity, cracked tooth, periodontal pocket, or erupting wisdom tooth can cause it.
What will the dentist check when a molar gum swells?
The dentist looks for redness, drainage, decay, a fracture, a pocket, limited opening, and an impacted tooth using examination and imaging.
When does back molar swelling need urgent care?
Clean gently, rinse with warm salt water, and do not puncture the swelling or apply concentrated chemicals.
What should you ask about a swollen molar gum?
Fever, pus, increasing swelling, restricted opening, or swallowing difficulty needs urgent care; breathing difficulty with facial swelling is an emergency.
Frequently asked questions
What is the first useful step?

Can I manage it only at home?
Home measures may reduce irritation, but they do not replace diagnosis when symptoms persist or worsen.
