Bf has red canker looking under tongue near saliva gland. now i am getting it. he cheated with unprotected. herpes? or what is it ? also white dots .

Many possibilities: It's best not to panic before you get checked since there are many types of red sores and white dots that occur in the mouth. There are many types of lesions that are found under the tongue other than herpes. Diagnosis of herpes in the mouth involve and exam and a viral culture of your outbreak. See your physician for the diagnosis.

Not likely: A single lesion for first herpes exposure is unlikely. I commonly have patients come in about white dots. Something got them to look in their mouth and the also noticed the white dots. Usually have always been there. Minor salivary glands or fat deposits. How long has the canker been there? More than 2 weeks? Need to see an oral surgeon for a diagnosis. Gone?Aphthous ulcer. They happen. No worries.
