I had neglected cavities in my front teeth for a long time, and they had become discolored and partially damaged. Since the front teeth are visible when smiling, I was most concerned about visible treatment marks. First, the cavity area was carefully treated, and then the damaged portion was filled with resin matched to the tooth color. It looks so natural that it's difficult to tell where the treatment was done, even when viewed up close. My front teeth, which had become dark in color and chipped in shape due to the cavities, have returned to their original appearance. The satisfaction is so high that I regret not getting treatment sooner.
