Bad teeth, slightly irregular, have little effect on the whole face. What is more serious is that most people, if they have buck teeth, will match one without chin. The wrong shape of dental arch will affect the mandible. First, the second is that many patients can't completely shut their mouths, so it is very easy to breathe through their mouths. Mouth breathing will aggravate the changes of jaw and face.
Because we are a very intuitive animal, we will first notice a person's face. It's okay when you don't laugh, but your teeth are exposed when you laugh. If it is a "loose" tooth, it will give people an impression and reduce the score. And it's white and neat. It's really beautiful.
In fact, a person's irregular teeth will not only affect the face value, but also affect health. Because when the teeth are uneven and overlap with each other, it is easy to accumulate dirt, which is difficult to clean, and may also cause tooth decay and periodontal disease.
