Having HIV and the side effects of some HIV medications can both affect your dental health, including reducing the amount of saliva in your mouth which can lead to tooth decay.

There is also an increased likelihood of gum and mouth disorders, such as oral thrush and badly bleeding gums, particularly during the early stages of HIV.

Emotional factors such as stress and anxiety, nutritional factors, as well as some HIV medications can cause a higher likelihood of teeth clenching and grinding. This can cause wearing of the teeth and make teeth sore and sensitive.
