Dentists use lasers for more than 20 Years to treat a number of dental problems. These lasers are different from the cold lasers used in other fields. State-of-the-art laser treatment makes for a significantly more pleasant experience than previously possible.
The laser can be used in a number of different ways, i.e.
· Infected tissue can be vaporised using laser, without damaging the tooth enamel
· necks of teeth that are sensitive to cold / hot can be “sealed” without any pain at all
· herpes or mouth ulcers heal faster if radiated gently.
· targeted disinfection and germ reduction for treating gum diseases or root canal treatments
· optimises the success of the overall treatment
· the tiny grooves in children’s teeth can be disinfected without “drilling” before they are sealed
· thorough removal of any remaining caries
· preserve any teeth that are at risk
· there is no need for scalpels or stiches because the laser closes any blood vessels immediately
Here are some of the major benefits associated with laser dentistry:
- Procedures performed using soft tissue dental lasers may not require sutures (stitches).
- Certain laser dentistry procedures do not require anesthesia.
- Laser dentistry minimizes bleeding because the high-energy light beam aids in the clotting (coagulation) of exposed blood vessels, thus inhibiting blood loss.
- Bacterial infections are minimized because the high-energy beam sterilizes the area being worked on.
- Damage to surrounding tissue is minimized.
- Wounds heal faster and tissues can be regenerated.
The Food and Drug Administration (FDA) has approved of a variety of hard and soft tissue lasers for use in the dental treatment of adults and children. Because dental lasers boast unique absorption characteristics, they are used to perform specific dental procedures.
- Hard Tissue Lasers: Hard tissue lasers have a wavelength that is highly absorbable by hydroxyapatite (calcium phosphate salt found in bone and teeth) and water, making them more effective for cutting through tooth structure. Hard tissue lasers include the Erbium YAG and the Erbium chromium YSGG. The primary use of hard tissue lasers is to cut into bone and teeth with extreme precision. Hard tissue lasers are often used in the “prepping” or “shaping” of teeth for composite bonding, the removal of small amounts of tooth structure and the repair of certain worn down dental fillings.
- Soft Tissue Lasers: Soft tissue lasers boast a wavelength that is highly absorbable by water and hemoglobin (oxygenating protein in red blood cells), making them more effective for soft tissue management. Commonly used soft tissue lasers include Neodymium YAG (Nd:YAG) and diode lasers, which may be used as a component of periodontal treatment and have the ability to kill bacteria and activate the re-growth of tissues. The carbon-dioxide laser minimizes damage to surrounding tissue and removes tissue faster than the fiber optic method. Soft tissue lasers penetrate soft tissue while sealing blood vessels and nerve endings. This is the primary reason why many people experience virtually no postoperative pain following the use of a laser. Also, soft tissue lasers allow tissues to heal faster. It is for this reason that a growing number of cosmetic dental practices are incorporating the use of soft tissue lasers for gingival sculpting procedures.
Some dental laser technology has been developed that can be used to generate both hard and soft tissue laser energy, depending upon the patient’s needs.
In addition to the lasers used for cutting and shaping hard and soft tissues, other laser types are specifically designed for viewing the insides of teeth and cells using Optical Coherence Tomography, a non-invasive imaging technique. Other lasers provide energy and specific proteins that help move messages between cells to match the body’s natural ability to use light spectrums to heal damaged cells.

If the dental laser 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.
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.
