Am I at risk for HIV?

Patient: About three days ago I had sex with another man. He claims he was disease free but I”m still nervous. I wore a condom and it didn’t break. However, I gave him a blow job and afterwords I realized that for the past week I had a deep indentation in my bottom lip from my braces. It has been super painful but hasn’t bled at all. He didn’t cum in my mouth and I didn’t taste pre cum during. I’m nervous that I could be at risk for HIV from oral sex with an abrasion in my mouth.
