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.
Lasers have been used in dentistry as a safe and effective treatment for a wide range of dental procedures in conjunction with other dental instruments.
How are lasers used in dentistry?
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 when performing cosmetic treatments.
- 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.
- help treat infections in root canals.
- speed up tooth whitening procedures.
What are the benefits of using dental lasers?
There are several advantages. Dentists may not need to use a drill or administer anaesthesia 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.
Are dental lasers safe?
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. All laser treatments require the adoption of appropriate safety precautions including wearing protective eyewear to protect eyes from the light beams emitted by laser equipment.
