Does the mouth naturally clean itself? does it shed skin and rejuvenate completely? do i need to worry about past sexual activity other than cold sore

See below: The mucosa does renew itself repeatedly and in that sense it is self cleaning. However, in addition to herpes, HPV is the other infection you need to be concerned about from oral sex. There is no urgency, but next time you see your doctor, discuss the details with her/him. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
