Bottom back gums hurt
Lower back gum pain can come from an erupting wisdom tooth, trapped food, gum inflammation, trauma, or a nearby tooth infection.
The short answer
Lower back gum pain can come from an erupting wisdom tooth, trapped food, gum inflammation, trauma, or infection in a nearby tooth.

Why can a wisdom tooth or nearby molar cause this pain?
A gum flap over a partly erupted third molar can trap plaque and food; a nearby molar infection can also refer pain into the jaw.
How can you ease lower back gum pain while arranging care?
Clean gently with a soft brush, rinse with warm salt water, and choose softer foods. Do not cut or puncture the gum.
When does lower back gum pain need a dental appointment?
Arrange care if pain persists, recurs, causes discharge, or limits opening. Fever or swelling is urgent.
What should you ask about the wisdom tooth and nearby molar?
Is the source the wisdom tooth, gum, or neighbouring molar, and is an X-ray needed?
