The largest benefit dental lasers offer to patients is the level of comfort they experience at the dentists office. This is not only because laser dentistry is more gentle, but because it can prevent further pain as well as minimalize time spent in the dentists office.
Traditional dental drills are powerful machines that use drill bits made of tungsten carbide, one of the hardest substances on the planet, to scrape off plaque or drill directly into tooth enamel. Although the heads of the bits are very small, they still tend to make holes that are larger than necessary, causing unneeded pain. They can also result in the cracking of healthy portions of the tooth. Despite technological advancements in traditional drills, they cannot compare to the precision of laser treatment. Lasers allow the dentist to narrow in on the exact area and deal with it without affecting the surrounding tissue.
Because of its precision, laser dentistry avoids sensitive tooth material. Often times erosion of enamel leads to dentine being exposed which causes painful tooth sensitivity. Lasers are minimally invasive, which means there is no pressure applied and thus less pain. This is because the affected area is being struck by a concentrated beam of light and not the hard material of the drill bit. Additionally, lasers can be used to seal the tubes that lead to the inner parts of the tooth, which is what causes high sensitivity.
The minimally invasive nature of lasers also means that no stitches are required in many gum procedures. The lasers sterilize the area and help the blood coagulate. The result is no uncomfortable stitches which are often painful to remove. Lasers can also be used to easily and painlessly remove canker sores or even tumors found on the inside of the cheeks.
Lasers also produce less heat and vibration than traditional drills. This allows for more control on behalf of the dentist, but also a more pleasant experience for the patient. During dental work, instead of hearing the loud-pitched wine of the drill patients experience a much softer noise . . . gentle tapping or popping.
Aside from the procedures themselves being less painful, laser treatment can also prevent future pain. Laser scans can be used to detect cavities early on and treat them before they become bigger. Because the laser is easier to control and only removes the decayed part of the tooth, there is a faster healing time. Because of simultaneous sterilization of the treated area, the procedures also tend to be more effective and have longer lasting effects.
