My gums started hurting all of a sudden nd also my teeth.. i feel a pulsing all over my mouth. along with nausea, migranes nd swollen glands. help?

Might be one of 2: You might have either anug or primary herpes.If you have a bad taste and the little points of gum tissue between your teeth are starting to disappear, along with your other symptoms, you likely have anug or trenchmouth. This is fast moving, very painful, and can be treated. Get to the dentist asap. Meantime drink plenty of fluids, take ibuprofen, and rest. But go soon. Very common with stress.

ANUG: You may suffer a condition call anug (acute necrotizing ulcerative gingivitis) or anup (acute necrotizing ulcerative periodontitis), a condition where a chronic infection of the gum/bone due to bacterial colonization combining with a poor body defense mechanism due to medical problems lead to an ulcerated, dying tissue surroungding the tooth (gum and/or bone). Debride, antibiotic, and follow up.
