Doctor I-Ann Chen specializes in: 1) Treatment of periodontal disease (gum tissue recovery procedure), 2) Gum aesthetic procedures: Clinical Crown enhancement procedure for frontal teeth, gum tissue implant procedure (improve gum degeneration); 3) Dental Implant. Peridontal disease is a chronic inflammation disease, and is rarely discovered unless acute symptoms such as pus or shaky tooth appear. Treatment effects are not optimal so regular maintenance of dental hygiene is recommended as well as dental checkups every 6 months. The earlier the treatment, the lower changes of the need for teeth removal.
