For reshaping gums and removing bacteria in a root canal procedure.
For the removal of a lesion or a biopsy to study the material.
For teeth whitening procedures where lasers can enable the acceleration of in-office teeth whitening. A bleaching solution made from peroxide is applied to the surface of the tooth and is ”activated” through the use of a laser which accelerates the process of whitening.
All lasers deliver light energy and when used in dental and surgical procedures, the laser plays the role of a cutting tool or a tissue vaporizer that it makes contact with. If it is used for the “curing” of a filling, the laser strengthens the bonding that occurs between the tooth and the filling. When utilized in teeth-whitening the laser plays the role of the provider of a source of heat which increases the results of agents of tooth-bleaching.
Benefits and drawbacks of using a laser in dental procedures
Often less pain is encountered reducing the necessity to use anaesthesia
Enhances patient comfort and stress because a drill is not involved
Reduces swelling and bleeding in the treatment of soft tissue
Is sometimes able to retain more of the healthy part of a tooth in cavity elimination.
It is not possible to use a laser on teeth which have fillings.
Lasers cannot be used to fill up cavities found between teeth, in the vicinity of old fillings and larger cavities that have to be prepared for the placing of a crown.
They are unable to eliminate silver fillings or defective crowns, or get teeth ready for bridges.
Traditional drills might have to be used to give the right shape to a filling, alter the bite, and give a polish to a filling even if a laser has already been used.
