The question of whether dentists can determine oral sex history is rooted in the examination of the soft tissues of the mouth, particularly the lips and cheeks. During oral sex, friction and pressure can cause subtle changes in the appearance and texture of these tissues. These changes can potentially include swelling, redness, or the development of small, white bumps known as Fordyce spots.
While these physical manifestations may suggest the possibility of oral sex, it is important to emphasize that they are not definitive indicators. Many other factors, such as allergies, smoking, and certain medical conditions, can cause similar changes in the oral mucosa. Therefore, dentists cannot make a conclusive diagnosis about oral sex history based solely on a physical examination.
