subject: The Magic Of Dental Lasers - They Make Fear Disappear [print this page] The use of dental lasers began some years back as a safer method of working on sensitive tissues in the mouth. In a way, laser technology in dentistry was at first lacking in some areas like dealing with hard tissues in the mouth. With constant development, lasers can now be used in many sensitive dental procedures.
For dental patients, fear of anesthetics is gradually being erased from their mind set. Lasers have made dental procedure convenient for dentists and painless for patients because there is no need for pressure on the tissues to be worked on. Because lasers work on beams, they do not produce sound, much less whines or other offensive noise.
However, drills are still the required tools to remove or repair metal dental fillings as lasers were not designed to deal with them. With mercury present in metal fillings, there is the risk of the mercury filling reflecting back into the eyes of the dentist.
When the laser beam hits the mercury fillings, a poisonous vapor is freed into the air. Like mercury fillings, gold inlays cannot be handled by lasers.
The new laser system has two features that complement each other. Lasers cut through hard tissue with precision by aiming at each specific molecule.
There is no danger of damaging the surrounding tissues because the laser beam has a high degree of collimation and, as such, it can directly hit the intended tiny spots to be worked on.
Being able to determine bad tissue from good tissue, the first laser automatically augments power to destroy a bad tissue and decreases it when it touches a good tissue.
The second laser is primarily designed for more delicate procedures on the gums, tongue, inner walls and other soft tissues and has similar features like those used by dermatologists.
Its energy levels can be adjusted depending on the kind of soft tissue to be worked on to ensure a gentle procedure. This technological advancement should end people's fear of the dentist.
People can now look forward to the laser as their ticket to healthier and more beautiful teeth, gums, mouths and smiles in as comfortable a way as possible.
The new laser is a must for every trustworthy dental professional. As long as mercury fillings are in use, the drill is here to stay even with the emergence of the mighty laser.
It is ideal for people on their initial visits to the dentist especially for children who have no mercury fillings. The use of the traditional drill is still important because the new laser cannot be used to work on decays caused by old amalgam fillings.
