It's not the teeth that make the lips thick, but some phenomena such as protruding mouth can make the lips feel thick visually, but it doesn't mean that it's the teeth that make the lips thick. Therefore, it is not necessarily thinner after the whole tooth is adjusted.

The thick lips are mostly caused by congenital inheritance, but don't worry too much, because the technology is very developed now, even thick lips can be thinned by surgery. At present, the methods that are widely used are "spindle resection" and "transverse and longitudinal prismatic resection".

In fact, the principle is almost the same. The operation is to remove the redundant mucosa and skin tissue from the inner and lower sides of the lips. And according to the specific situation, a part of the muscle layer may be cut off, and then the inner side is pulled closer and stitched. Because the muscle will not grow back after removal, the surgical effect can basically be maintained.

However, it does not rule out the sequelae such as the thickening of lips, asymmetry of upper and lower lips and unsatisfactory results due to doctors' poor skills or their own failure to do a good job in postoperative care. The operation is simple, the effect is obvious and lasting, the scar incision is hidden, usually an intraoral incision, and there are usually no side effects.
