Is it normal for my gums to bleed and hurt a little from using electric toothbrush?

Bleeding gums: You may have gingivitis or/and periodontal disease. Plaque is a sticky bio film that can be removed with a toothbrush, calculus is a harder and attaches itself to the tooth and root surface and needs to be removed professionally by a hygienist or dentist. See you dentist for an evaluation.

Maybe, maybe not: Without actually examining you, we cannot give you an accurate answer to your question. Gums should not bleed. It may be due to overzealous or improper use of the toothbrush, early gum problems, or more serious periodontal disease; or even other dental and\or medical problems. When was your last dental check-up and cleaning? It's best to see your dentist and find out what's going on.
