Question and answer

Why is my gum inflamed and sore

Inflamed, sore gums most often result from plaque at the gum margin, but trauma, hormonal change, medicines, or infection can also contribute.

The short answer

Inflamed, sore gums most often result from plaque at the gum margin, but trauma, hormonal change, medicines, or infection can also contribute. A dental examination checks whether inflammation is limited to gingivitis or has affected deeper supporting tissues.

What is the direct answer?

What does this question mean?

Gingival inflammation makes the gum red, puffy, tender, and prone to bleeding. If plaque hardens into calculus, brushing cannot remove it completely, and inflammation may persist around or below the gumline.

What can you do next?

Brush twice daily with fluoride toothpaste and clean between the teeth every day, working gently at the gumline. A dental hygienist can remove calculus, after which the home routine can control new plaque accumulation.

When should you seek dental care?

Arrange care for ongoing bleeding, bad breath, gum recession, loose teeth, or pain when chewing. Urgent assessment is needed for rapid swelling, pus, fever, or difficulty swallowing or breathing.

What should you ask the dentist?

Ask whether you have gingivitis or periodontitis, where plaque and calculus are collecting, and whether a cleaning or periodontal measurements are needed. Mention recent medicines, pregnancy, smoking, diabetes, or mouth injury if relevant.

Frequently asked questions

Should you stop brushing sore gums?

No. Gentle brushing at the gumline helps remove the plaque that drives inflammation.

Can sore gums be caused by a new medicine?

Some medicines can alter gum tissue or saliva; tell the dentist what you take so the cause can be assessed.
