Dentistry

Laser beams are already used in dentistry and in medical practice. But lasers are currently not used for everyday dentistry, such as the drilling of teeth. In the future, as laser technology becomes more refined, lasers may take the place of many conventional dental tools. Using lasers instead of dental tools would cut down on the opportunity to be exposed to blood-borne illness, and reduce damage to surrounding tissue.

Researchers also are exploring new ways to treat periodontal disease, such as more specific antibacterial therapy and stronger antibacterial agents. Many researchers also see a stronger role for fluoride in the future, in addition to its current presence in many public water supplies. Some dentists advocate the use of fluoride in sealants. A 1991 study reported that a sealant including fluoride reduced tooth irritation for some individuals with sensitive teeth.

While dentistry has made immense progress since days when a dead mouse was considered high dental technology, there is still progress to be made. Future challenges for the dental profession include continuing to reduce tooth loss and decay due to neglect and the aging process.
