It was fine when I first took off the retainer, but after a few days, the retainer on the lower left pressed against the gum, and there was a mark, which would hurt every time I put it on again. What should I do? Disease analysis: Hello, the indentation on the gum surface is probably caused by improper fixture making, which has little to do with wisdom teeth, and can be adjusted appropriately to avoid continuous damage to the gums.

Suggestion: It is suggested to go back to the dental clinic as soon as possible to adjust and polish the retainer at the compressed part of the gum to restore the health of the gum.
