There are three general categories where Lasers in Dentistry falls into: Disease detection, Soft tissue treatments, and Hard tissue treatments.
There are many ways lasers can aid in diagnosis. Laser light of specific wavelength can detect tiny pits and fissures in the biting surfaces of the tooth that a traditional dental tool can’t find. This enables a defect that’s too small to be treated at present to be carefully monitored. Lasers can also help locate dental calculus beneath the surface of the gums, and can even aid in the detection of oral cancer in its early stages, accurately showing where healthy tissue ends and diseased tissue begins.
For the treatment of soft tissue problems, lasers have many advantages. They are minimally invasive tools that generally involve taking away less tissue than conventional methods. Used in gum surgery, for example, lasers can treat gum disease by killing harmful bacteria deep in pockets below the gum line, and removing the diseased tissue without harming the healthy tissue. They can also remove the thin layer of cells that inhibits reattachment of the gum and bone tissues to the tooth, while sealing off the adjacent blood vessels. This type of procedure generally results in less bleeding and pain. Lasers are also effective in treating ulcers and sores on the lips or gums.
Lasers are even finding increasing use for hard-tissue procedures, like the treatment of dental caries and cavities. Not only are they more exact in the amount of material they remove, but they eliminate the noise and vibration of the dental drill, which is uncomfortable for some patients.
