I am the legendary "Lu Pei" and want to do orthodontics. That hospital in Qingdao is better and cheaper.
This is not a dental problem, it is a mandibular problem, so your situation should not be considered as a dental problem.
Mandibular plastic surgery should be done as early as possible, preferably as a child, with less pain. If you are an adult, there is no need to consider cosmetic surgery. Suffering is not necessarily ideal.
