Dr. Lorman put some material between my front teeth to fill some gaps for aesthetic purpose. One of the teeth curved in so he redid it. The following day when I ate an apple, the new material fell off. I went back for a third time and he admitted that he had "skiped" a step. I wonder why. After a year, some seed got inside which reflects that the tooth was not sealed and therefore, he did it incorrectly once again.
He also put some material on my retainer and the material came off after a week.
