What to do if i have a problem with my gum. it breeds every time i brush, or eat frruits. why does that happen.?

Likely Gingivitis: Might be caused by bad hygiene of the mouth... food gets stuck between teeth and gum gets infected and starts bleeding. You need to do regular flossing and take all the food residue out, and also to see the dentist for check up every 6-12 months Other causes might be use of certain medications or due to increased bleeding tendency of your body. The latter two are to be checked with your doctor

Bleeding gums: Having bleeding after brushing teeth or eating can be a sign of serious illness or disease. Commonly gingivitis and oral health are reasons for bleeding gums. A dentist is the best place to seek care and determine the cause of bleeding gums.
