"We get many questions about kissing and oral exposure and whether or not the presence of a cold sore, bites to the lip, gum disease or other wounds in or around the mouth changes the answer to the question.  The answer is no.  The data which define the absence of any risk of getting HIV through kissing, deep or otherwise has be generated through studies of thousand and thousands of persons, some of whom had cold cores, cuts, etc.  There is no risk"  DR HOOK / MEDHELP
