Risks and Benefits
According to the Academy of General Dentistry (AGD), there are ample benefits to using lasers for excising diseased gum tissue:
- No general anesthetic is needed, as is sometimes required for other forms of dental surgery.
- Lasers can target the diseased areas precisely and accurately.
- Bleeding, pain and swelling are limited because periodontal laser therapy is less invasive than regular surgery.
- Recovery and healing times are shorter.
Some medical authorities don't yet support the use of this therapy. However, the AAP, suggests there is insufficient evidence that any particular laser's wavelength is better than traditional treatment. This doesn't mean the AAP is against the practice, but you should still play it safe until more professional associations approve this practice – particularly with regard to the restoration of tissue after therapy.
Nevertheless, there are some risks to the use of laser periodontal therapy. One of these is the fact that you're a human being; if your dental professional uses an inappropriate wavelength or power level, it could cause further damage to the periodontal tissue. There is also concern among providers that advertising hype is attributing more to this therapy than it should.
