Before, my mother had fixed her teeth several times in two clinics outside the city within one year, but it never worked out. She went to the hospital at the end of 1 1, and it has been almost two years since then. My mother didn't want to go to the hospital before. It was more expensive. Then I thought it was worth going. No matter from the aspects of hygiene, equipment or environment, it is incomparable to the clinics outside.
