What is a laser and how does it work?
A laser is an instrument that produces a very narrow, intense beam of light energy. When laser light comes in contact with tissue, it causes a reaction. The light produced by the laser can remove or shape tissue.
Are lasers used in dentistry?
Yes, lasers have been used in dentistry since 1990. Lasers can be used as a safe and effective treatment for a wide range of dental procedures and are often used in conjunction with other dental instruments.
Dental lasers can be used to:
- reduce the discomfort of canker and cold sores.
- expose partially erupted wisdom teeth.
- remove muscle attachments that limit proper movement.
- manage gum tissue during impressions for crowns or other procedures.
- remove overgrown tissues caused by certain medications.
- perform biopsy procedures.
- remove inflamed gum tissues and aid in the treatment of gum disease.
- remove or reshape gum and bone tissues during crown lengthening procedures.
- help treat infections in root canals.
- speed up tooth whitening procedures.
There are several advantages. Dentists may not need to use a drill or administer anesthesia in some procedures, allowing the patient to enjoy a more relaxed dental experience. Laser procedures can be more precise. Also, lasers can reduce symptoms and healing times associated with traditional therapies; reduce the amount of bacteria in both diseased gum tissue and in tooth cavities; and control bleeding during surgery.
If the dental laser is used according to accepted practices by a trained practitioner, then it is at least as safe as other dental instruments. However, just as you wear sunglasses to protect your eyes from prolonged exposure to the sun, when your dentist performs a laser procedure, you will be asked to wear special eyeglasses to protect your eyes from the laser.
