There is no good stomatological hospital near Amethyst Harbor. If you want to run a little further, take bus No.89 to Gudang. There is a Gucui branch of Hangzhou Stomatological Hospital, which is not bad. It is also the nearest regular stomatological hospital. Tel: 057 1-288003 15.
Everything else is private or carefully selected. However, there is a Heha Stomatological Hospital at the junction of Gudun Road and Tianmushan Road, which should be ok. You can take the 17 bus directly to the ceramic market. But the charge is not low.
