Do TWO things.: Start to correct your low B12 levels, and more rapid way is to inject once monthly. (Might want to explore why levels are down.) Secondly, re-contact your dentist and get your gingivitis under control. Do both, do not prioritize. All should work out.

No research has shown that B12 deficiency can cause bleeding and swollen gums but severe Vitamin C deficiency called Scurvy can cause swelled and Bleeding gum . If your Dentist has cleaned your teeth as first line of treatment is fine otherwise,you need to have a good cleaning for good Oral hygiene . At your age the swollen ,bleeding gum in spite of good Oral Hygine May be due to Hormonal changes
