What should I do about gum recession with a porcelain-fused-to-metal crown?

Change your toothbrushing technique by using a soft-bristled toothbrush and avoid over-brushing or using a brush head that is too hard. If periodontitis is present, periodontal treatment is necessary, including teeth cleaning and root planing. For severe cases of gum recession, periodontal surgery may be required, such as soft tissue grafts or bone grafts to restore gum tissue. Other treatment options may also be considered, such as laser therapy and oral health products.
