What you need to know about Dental Lasers

December 13, 2017

Lasers have been in the dental field for some time now, but over the last couple of years have really become a popular topic. More dental offices are starting to see the benefits lasers can provide to their patients and instead of a cool tech fad, they are slowly becoming the standard of care. Patients are usually unsure of what services lasers can provide, and it is our job to inform you. Lasers can be utilized by both dentists and dental hygienists to bring the best care to our patients. Below we’ve outlined a few of the main functions of laser dentistry.

Dental​ ​Hygiene:​ Lasers can be used on a day to day basis performing “Laser Bacterial Reduction (LBR).” LBR can benefit all patients regardless of their periodontal condition or history. The function is as the name states, to reduce the number of periodontal pathogens in the gum pockets. This leads to less bleeding and inflammation at subsequent visits and creates an overall healthier oral cavity. Another procedure your hygienist may perform with the laser is “Gingival Curettage.” This is an adjunctive procedure used in addition to scaling and root planing (SRP or Gum Therapy) for patients with active periodontal disease. Gingival curettage is the act of removing infected tissue within the pocket and is a quick and beneficial addition to SRP therapy. Utilizing this adjunct therapy, many dental professionals have seen fewer bleeding points and less inflamed tissue post procedure. Removing necrotic tissue and reducing bacterial pathogens within the pockets allows the gum tissue to heal more quickly.

Tooth​ ​Whitening:​ There are several methods of tooth whitening, but the laser option typically causes less sensitivity than more intense UV options. Patient’s teeth have been noted to become about 2-3 shades lighter after laser whitening and for patients with already sensitive teeth, this is a good alternative and can be followed up with at home whitening trays.

Decay​ ​Removal/Cavity​ ​Preparation:​ There are two main types of lasers, those that cut soft tissue only and those that cut both hard and soft tissues. The latter form can be used in decay removal and to prepare cavities for fillings. The advantage of this method is that patients often experience little to no discomfort even when they are not numb. It does take a bit longer than traditional decay removal, but usually doesn’t require more chair time if the patient doesn’t need anesthetic.

Aphthous​ ​Ulcers/Herpetic​ ​Lesions:​ ​Many patients suffer from aphthous ulcers (canker sores) and Herpetic Lesions (cold sores), both of which can be very painful. Early research has shown that treating these lesions with the laser leads to less discomfort for the patient and faster healing times. There are various reasons this may be occurring with the laser treatment which include, dehydration, possible biostimulation, decontamination, and potentially preventing the Herpes Virus from replicating.

As more research is done on the effects of lasers and their benefits, we will continue our education and strive to provide you with the highest quality care. If you have more questions about lasers feel free to ask your hygienist at your next dental visit! Dental Care of Sumner is not currently using dental lasers in our office, but we are hoping to introduce them into your dental care in the future!
