What is the direct answer?

A sore lower gum can come from plaque inflammation, trauma, an ulcer, a tooth problem or infection around a partly erupted tooth.

What does this question mean?

The lower gingiva surrounds lower tooth roots and borders the floor of the mouth. Soreness may be localised or widespread.

What can you do next?

Causes include gingivitis, food or brush injury, an ulcer, appliance rubbing, decay, a crack or wisdom-tooth inflammation.

When should you seek dental care?

Rinse gently, choose soft foods, avoid tobacco and very hot or spicy foods, and keep cleaning gently. Do not place aspirin on the gum.

What should you ask the dentist?

Arrange care for persistent, recurrent or lumpy soreness. Swelling, fever, pus, swallowing difficulty or limited opening is prompt-care territory.

Frequently asked questions

Could another condition cause this?

What should the dentist check?
