The causes of convex mouth are different: false convex mouth is mainly caused by teeth, also known as tooth convex mouth. Generally, there are genetic factors, but it is more because of the bad oral habits of beauty seekers, such as sticking out your tongue and biting foreign bodies when you were young. Generally speaking, the upper and lower incisors are inclined to the lips, and the incisors cover the upper teeth.

The real convex mouth is mainly a bone problem. The teeth of beauty seekers may be neat, but the bones bearing the teeth protrude forward or over-develop, which is also called bone protrusion. This is a problem of maxilla, which is mainly caused by the development of maxilla and mandible.

Look at the smile: bony protrusion is caused by "over-replication of maxillary development", which is not only a forward-backward transition, but also a vertical transition. Vertical transition marks a grimace, so when you see an obvious grimace, it is inseparable to judge the bony process.

Matters needing attention in correcting convex mouth

1, Orthodontics: Skeletal buckteeth: There are genetic factors, but bad oral habits can also lead to skeletal buckteeth, such as spitting out the tongue and biting foreign bodies. Bone buckteeth are generally loose, lips can not be closed normally, and many gums will be exposed when laughing. The main manifestation is that the upper and lower incisors are inclined to the labial side, and the front teeth cover the lower teeth.

2, orthognathic surgery: Although the teeth are neat and beautiful, the convex mouth will still have a great impact on the appearance, and may also lead to some oral side effects. Generally, minor dental problems can be solved by wearing braces, but if it is a serious problem, it cannot be solved by wearing braces alone, and it can only be improved by orthognathic surgery.
