Teeth whitening is a process of removing stains from the tooth surface and restoring the natural color of the teeth. Whitening is a one-time procedure performed by a dentist. It is amongst the most common and widely adopted procedure. With the advent of the latest Dental technology, we have advanced whitening treatment procedures which give reliable and long-lasting results.
For better results do get it done from a trained dental professional.
Laser dentistry provides patients with a better experience and quality. Even though laser dentistry is mainly associated with cosmetic treatments, it is equally effective for preventative purposes. It potentially offers a more comfortable treatment option for a number of dental procedures involving hard or soft tissues compared to drills and other non-laser tools.
All lasers work by delivering energy in the form of light. When used for dental procedures, the laser acts as a cutting instrument or a vaporiser of the tissue that it comes in contact with. When used in teeth-whitening procedures, the laser acts as a heat source and enhances the effect of tooth-bleaching agents.
Instead of needles and drills, laser dentistry uses Heatand light to treat Dental infections. Thatβs why the procedure is less painful.
The word LASER is an abbreviation for Light Amplification by Stimulated Emission of radiation.
The concept of lasers is based on Einsteinβs theory of stimulated emission. Lasers are used in a wide range of medical and cosmetic procedures. Recently it has received attention in clinical dental settings. With minimal anaesthesia, lasers ablate the hard tissues. Bacterial counts in root canals are also reduced with the help of laser treatment. There are different ways by which lasers are used in dentistry. During surgical procedures of soft tissues, good hemostasis can also be achieved with their use. The most common types are carbon dioxide (CO2), diode, neodymium: yttriumβ aluminumβgarnet (Nd: YAG), and erbium: yttriumβaluminumβgarnet (Er: YAG) lasers. They are used for cavity preparation, tooth whitening, gingival incisions, and other applications.
Lasers are categorised by various methods, however broadly, they are classified into two categories β hard or soft tissue lasers. This is because some are too abrasive for soft tissue while others arenβt abrasive enough for hard tissue. Some can be used interchangeably if their wavelength allows it.
The essential use of this laser is to cut the teeth with exact precision. It cuts into the teeth and bones with accuracy. This laser treatment is perfect during the cutting of the tooth structure.
The wavelength from the intricate tissue laser is highly absorbable by hydroxyapatite. Besides, the lasers include Erbium Chromium YSGG and Erbium YAG.
Hard tissue laser also helps in preparing or shaping the teeth with composite bonding. It helps in the removal of small tooth structures and the healing of dental tear fillings.
Some common hard tissue procedures include:
Soft tissue lasers can highly absorb water and haemoglobin, making them suitable to treat problems in the soft tissue. Likewise, the soft tissue lasers include Neodymium YAG with diode lasers. It helps in killing the bacteria in the mouth and helps reactivate the growth of the tissues.
Some common soft tissue procedures include:
You must be curious about what laser dentistry is used for. Well, there are a lot of dental treatments that are being replaced by pain-free laser dental treatments like:
Lasers can remove tumours from the palate, gums, and sides of the lips and cheeks through pain- and suture-free methods.
Local anaesthesia and traditional drills are often not needed with laser treatments. Lasers can kill bacteria in a cavity, which can aid in the long-term health of a tooth.
Teeth that have sensitivity to hot and cold can be treated with dental lasers that seal tubules on the toothβs root.
Lasers are used to reshape gum tissue associated with a βgummy smileβ in which the gumsβ length covers much of the tooth.
This procedure reshapes both gum tissue and bone for healthier tooth structure, which helps with placing restorations on the teeth.
Those with a thick or tight frenulum (the fold of skin under the front part of the tongue that anchors to the mouth floor) may benefit from a laser frenectomy. This treatment helps children whose restricted frenulum causes them to be tongue-tied, have difficulty breastfeeding, or have a speech impediment.
Lasers can remove soft tissue folds from ill-fitting dentures without pain or sutures.
Different laser treatments require different processes and approaches. It depends from case to case and patient to patient, how much the cost will be.
