Dental Laser

1. Treating hypersensitivity
2. Treating tooth decay
3. Treating gum disease
4. Whitening teeth

The two main types of procedures used for laser dentistry are hard tissue and soft tissue procedures. Hard tissue refers to the teeth, and soft tissue refers to the gums.

Common hard tissue procedures include:

• Cavity detection. Lasers can detect cavities early by finding evidence of tooth decay.
• Tooth preparations and dental fillings. Local anesthesia and traditional drills are often not needed with laser treatments. Lasers can kill bacteria in a cavity, which can aid in the long-term health of a tooth.
• Treating tooth sensitivity. Teeth that have sensitivity to hot and cold can be treated with dental lasers that seal tubules on the tooth’s root.

Common soft tissue procedures include:

• Treating a “gummy smile.” Lasers are used to reshape gum tissue associated with “gummy smile,” in which the gums’ length covers much of the tooth.
• Crown lengthening. This procedure reshapes both gum tissue and bone for healthier tooth structure, which helps with placing restorations on the teeth.
• Treating tongue frenulum attachment. Those with a thick or tight frenulum (the fold of skin under the front part of tongue that anchors to the mouth floor) may benefit from a laser frenectomy. This treatment helps children whose restricted frenulum causes them to be tongue-tied, have difficulty breastfeeding, or have a speech impediment.
• Removing soft tissue folds. Lasers can remove soft tissue folds from ill-fitting dentures without pain or sutures.

Other laser procedures include:

• Viewing tissues. Optical coherence tomography allows a doctor to safely see inside a tooth or gum tissue.
• Removing benign tumors. Lasers can remove tumors from the palate, gums, and sides of the lips and cheeks through a pain- and suture-free method.
• Treating obstructive sleep apnea. Lasers can reshape the throat and relieve associated breathing problems when sleep apnea is caused by tissue overgrowth in the throat.
• TMJ (temporomandibular joint) treatment. Lasers can help reduce pain and inflammation in the joint.
• Nerve regeneration. Lasers can help regenerate damaged blood vessels, nerves, and scars.
• Treating cold sores. Lasers can minimize healing time and reduce pain from cold sores.

Teeth whitening. Lasers speed up the bleaching process during teeth-whitening sessions.

• There is potentially a decreased need for sutures with soft tissue lasers.
• Bleeding is minimized in treated soft tissues, as the laser promotes blood clotting.
• The chance for bacterial infections is lower because the laser sterilizes the area.
• Wounds can heal faster, and helps the tissue to regenerate.
• The procedures may involve less damage to the surrounding tissues.

Soft tissue lasers can be absorbed through water and hemoglobin. Hemoglobin is a protein found in red blood cells.

These lasers are used to treat periodontitis, including killing bacteria and activating tissue regrowth.

Soft tissue lasers seal nerve endings and blood vessels while they penetrate the tissue. For this reason, many experience almost no pain after laser treatment. The lasers also promote faster healing of the tissue.

• Lasers can’t be used on teeth that already have certain types of filling, such as metal amalgam.
• Hard lasers can sometimes injure tooth pulp.
• Some laser procedures still require anesthesia.
• Drills are still sometimes needed to complete fillings, including shaping, adjusting the bite, and polishing the filling.
• Certain procedures can’t be done with laser treatment, depending on the preexisting surrounding tissue or components involving the tooth or gums.
• There is a risk of gum injury.

The risks of laser dentistry are relatively small. It’s important to find a qualified dental professional, as using the wrong wavelength or power level could damage tissue.
