Medical professionals use lasers, which are extremely focused light beams, to alter or remove tissue in small amounts. Laser surgery is not limited to dentistry, but many people have never heard of laser dentistry before having it done. Dentists use lasers in a variety of procedures involving the inside of the mouth, be it to remove overgrown tissue, to reshape the gums, or to whiten teeth. Sometimes, laser dentistry is ideal for children who become anxious or afraid when having dental work done.

What Laser Dentistry Can Treat?

Most issues laser dentistry treats are related to the gums. Some of these include:

  • Canker sore and cold sore pain treatments.

  • Treating root canal infections.

  • Treating gum disease.

  • Removing gum inflammation.

  • Gum reshaping.

  • Biopsies.

  • Exposing wisdom teeth.

  • Removing throat tissue that causes sleep apnea.

  • Regenerating damaged nerves.

  • Removing benign oral tumors.

The Types of Lasers Used in Dentistry

The two main types of lasers dentists use during laser procedures are hard tissue and soft tissue lasers. Each laser uses a different wavelength that makes it appropriate for cutting into that specific type of tissue. This works because each kind of tissue absorbs wavelengths of light in different ways. By altering the light’s wavelength (and sometimes pulse) scientists have figured out how to craft lasers with light wavelengths compatible with the tissues in your mouth.

Benefits of Laser Dentistry

Dentists choose laser dentistry because of distinct benefits that make the procedures go more smoothly, and also reduce discomfort and healing time for patients.

  • Patients are less likely to require sutures

  • Anesthesia may not be necessary

  • The laser will sterilize the gums, making infection less likely

  • Less damage to gums shortens the healing time

  • Patients lose less blood than traditional surgery
