Can an std cause bleeding of the gums and your teeth to be sore?
An STD is an infection and you can get one in your mouth if you go chomping on something that carries the infection, so you need a trip to the doctor pronto. Fortunately, they can be treated pretty well with antibiotics. Might not be a bad idea if you dragged your sex partner along for a test too. Gingivitis carries those sort of symptoms too, so although it’s not an STD, whatever you’ve got needs some treatment.
