There is no evidence to suggest that dentists can tell if someone has given head. This is a false and harmful myth that has been perpetuated for many years. There is no scientific basis for this claim, and it is important to remember that dentists are healthcare professionals who are dedicated to providing their patients with the best possible care.
The spread of misinformation about oral sex and dentistry can have a negative impact on people's health. It can lead to people avoiding necessary dental care out of fear or embarrassment. It can also lead to people being subjected to unnecessary or harmful procedures.
