Beauty tooth training in 2022 is a scam. According to relevant data, dental training is a long-term process, and it is impossible to speed it up in three days. The purpose of oral beauty is to improve the smile, which involves the comprehensive medical treatment, health care and service of lips, teeth and gums.

The beauty of lips is mainly to improve lip shape and lip line, the beauty of teeth is mainly to improve arrangement, color and shape, and the beauty of gums is mainly to improve shape and health.
