HIV infection and HIV treatments are associated with a decrease in the normal amount of saliva produced, which in turn can lead to increased risk or tooth decay. Saliva decreases the acidity produced by bacteria in the mouth, and so helps to prevent the loss of calcium and phosphate from the enamel on your teeth.
HIV infection also decreases oral health generally. Many HIV-positive people develop oral fungal, bacterial, or viral infections in the early stages of infection.
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.
