Lasers can be used to treat periodontal disease. Current controlled studies have shown that similar results have been found with laser treatment compared to specific other non-surgical treatment options, including scaling and root planing alone.

Each laser has different wavelengths and power levels that can be used safely during different periodontal procedures. However, damage to periodontal tissues can result if a laser with an inappropriate wavelength and/or power level is used during a periodontal procedure.
