AIDS is mainly transmitted through blood, genitals, sexual contact and other body fluids, as well as mother-to-child transmission. If the oral cavity was not damaged during the tooth cleaning, there is no need to worry about being infected with AIDS, and the probability of transmission is not great. Even with HIV, it can't survive after entering the human digestive tract.
HIV is mainly attached to the immune cells of the human body. Once you leave the human body and come into contact with air and sunlight, the survival rate is extremely low, so you don't have to worry about it. The human body itself has immunity and can resist diseases, so we must have some confidence in our body.
Now you should mainly control yourself, try not to think about this problem, divert your attention and learn more about medicine, and naturally you won't have the above doubts. ..
