Suggest Treatment For Sore On The Tongue

The risk of HIV/STD with kissing in presence of a sore is negligible.
Detailed Answer:
Hi,
Welcome to HCM.
Thanks for posting your query.
First of all, your girl friend is not necessarily be infected with HIV or STD.
HIV is not present in human saliva in adequate concentration to cause a new infection unless it is contaminated with blood. Chances of STD through deep kiss is remote unless the individual has an obvious oral lesion (except Herpes simplex 1 infection -not a STD primarily).
At the same time presence of an sore in your mouth (discontinuity of the covering structure) will likely to increase the chance of getting an STD/HIV to a little extent, if that lady has something. But the risk through deep kissing is negligible as per CDC, XXXXXXX
