There are other areas in which laser technology is having an impact on dentistry, too. For example, optical coherence tomography (OCT) is a safe way of viewing the inside of your teeth and gums. Laser dentistry can play a role in the painless removal of benign tumors from your gums, palate, lips, and cheeks, and it provides a more comfortable option for treating cold sores. Lasers also offer a faster way of performing teeth whitening. Damaged blood vessels and nerves could regenerate more quickly with the use of photobiomodulation or low-level laser therapy, and laser-assisted uvuloplasty (LAUP) is an innovative solution to treating sleep apnea.
