A periodontist is a gum specialist. A gum surgeon. Load up on Coq10 and vitamin C for a week and see if you're better. Sounds like your immune system is running on low.
When my gums became really sensitive I began using Sensodyne toothpaste. One week later the pain was GONE and I've been using it for 20 years just like my mother. But the bleeding is another matter and shows a vitamin deficiency.
really? the white bump could be related to my gums? i've been trying to floss and use mouthwash more but is a periodontist a dentist or someone more specific?
If bump is reactive lymphoid tissue, it may be related to orodental infection, specifically, you may have periodontitis. Seeing a periodontist is advised.
