Wearing Frank 3 results in a convex mouth

The teeth are moved by the force, and the braces are not adapted to be worn.

1, teeth force movement: when wearing Frank 3 for orthodontic treatment, the teeth will be affected by the orthodontic force and move, resulting in a change in the shape of the lips, resulting in the phenomenon of convex mouth.

2, braces wear discomfort: when wearing Frank 3 for the first time, the feeling of foreign objects inside the mouth will lead to discomfort in the lips, resulting in convexity of the mouth.
