Receding Gums Teeth I Had Gum Grafting For Receding Gums, But Can Still See The Root On One Of The Teeth; Is This Normal?

I had gum grafting for receding gums, but can still see the root on one of the teeth; is this normal? - receding gums teeth

Chewing gum had more setbacks in a deeper side than on the other side of my jaw. It has been grafted a total of 2 wheels and a toe side. In part, the most I saw was 1 to 2 millimeter edge of the real root of the tooth. It's better than before, but I was hoping that would cover the root after recovery. My periodontist said that was "the court, only in the blood, but it is as long as I do." This seems right or not getting cheated by the amount of money they pay?
