Tongue over palate does not generally correct the shape of the face.
The shape of a person’s face is mainly adjusted by the facial bones and the bite muscles, but some people have overly protruding teeth, which makes the shape of the face unattractive, and the action of the tongue against the palate does not affect the shape of the face, so it will not be able to achieve the effect of correcting the shape of the face.
If there exists the phenomenon of protruding teeth, resulting in an unattractive face shape, you can go to a professional hospital to correct it by wearing braces, and if it is a factor of bone development that leads to an unattractive face shape, you can undergo orthognathic surgery or bone grinding surgery and so on to improve it.
If you have an unattractive face shape, it is recommended to go to a professional hospital to clarify the cause and adopt a suitable solution under the guidance of the doctor.
