don't go to dentist for big surgery then... go to orthodontist.. if you believe in China.. then why ask? just go .. we are all strangers to you... people told you to stay here, will you stay? people say China is much better... do you truly believe in the person other than the fact he/she agreed with you? I've been to both dentist for small things and orthodontist for big fixes. both are done correctly without issue.
Worse comes to worse, you sue the dentist/orthodontist.
Lastly, if you don't know what orthodontist is, just google it.
