French kissed this guy twice. lips and gums burn and gums aches. for more than a week. no blisters, bumps or cold sore. whats wrong?

Sounds like: Viral infection from your description , did either you had any open sores or blisters when that happened? An examination and a cutler may be needed.

Ask your doctor: There are many conditions associated with pain or discomfort, soreness or burning inside of mouth and swollen gums. It could be toothbrush irritation and/or dental abscess. Any of these symptoms are more than just annoying; they can indicate a serious medical condition and require prompt medical diagnosis by your dentist or pcp.
