Laser Dentistry | The White Arch Dental Centre

Laser light is amplified light emitted from a fibre, hollow wave guide or handpiece through a machine, due to stimulated emission of radiation. All lasers work by delivering energy in the form of light. When laser light falls on tissues, it either gets absorbed, reflected, transmitted or penetrated. The most desirable is absorption. When used for surgical and dental procedures,the laser acts as a cutting instrument or vaporizer of tissue that it comes in contact with. When used for curing or filling, the laser helps to strengthen the bond between the tooth and the material. When used for teeth whitening, it helps to speed up the whitening process by activation of the bleaching agent. All lasers are used with strict protocol of precaution. Laser safety in the form of protective eyewear, plume control and adequate warning are always followed to ensure safety of the patient, operator and the assistant.

There are different wavelengths of dental lasers.

The Diode laser 810 nm which is a fibre optic delivered soft tissue laser which is used for incision, ablation , sterilization and soft tissue surgeries.
The Nd: YAG laser wavelength 1064 nm is a fibre optic delivered soft tissue laser used for soft tissue surgeries and root canal sterilization.
The CO2 laser 10,600 nm is a hollow wave guide delivered soft tissue laser used for soft tissue surgeries, and management of dentinal hypersensitivity. It provides excellent hemostasis or bleeding control during surgery.
The Er: YAG laser 2940nm is a handpiece delivered all tissue laser which acts on both the tooth surface, bone  as well as the soft tissues. It is also called an All Tissue Laser. It is a very promising modality of treatment to the patients. Due to its highest superficial impact and minimum depth of penetration into the tooth or surrounding gums and bone, it is painless, causes minimal thermal damage and promotes fastest healing. Most of the times no anesthesia is required. This laser can be used for almost all the procedures in dentistry. It has a mild effect of biostimulation to promote wound healing.
LLLT is Low Level Laser Therapy which usually works between 660-950 nm. It is used for stimulating wound healing, pain control, reducing sensitivity of teeth , TMJ disorders, facilitating Orthodontic tooth movement etc. Photodynamic therapy is one type of LLLT which uses photosensitive dyes activated by light for bactericidal action, facilitating treatment of dental caries, gum pockets, periimplantitis (infection around implants), disinfecting oral tissues etc.

LASER PROCEDURES :
Root Canal disinfection
Gum pocket sterilization
Curettage
Smile designing
Crown lengthening procedure
Gingival /Gum depigmentation- Treatment of dark or pigmented gums
Frenectomy
Excision of soft tissue growth such as fibroma, papilloma etc
treatment of sensitive teeth.
Bleaching / Teeth whitening
Frenectomy etc.
Management of Periimplantitis (Infecion around dental implants)

However lasers can be used as adjuncts to all most all  treatment procedures.
