Lasers have transformed our everyday lives, especially in healthcare. These intense beams of light of a single wavelength have revolutionized all manner of diagnostics and treatments, from general surgery to cosmetic therapy.
Dentistry has also been influenced by the laser revolution. Here are just a few of the areas where they’re growing in use and popularity.
Early disease detection. Laser instruments can take advantage of “fluorescence,” the tendency of bacteria to “glow” when exposed to certain wavelengths of light. This is proving more effective in detecting early tooth decay in pits and fissures (very tiny areas in a tooth’s biting surface) than traditional needle-like probing instruments called dental explorers. Newer lasers can now detect the same fluorescent qualities in soft tissues, which may reduce the detection time for oral cancer and make the difference between life and death.
Dental caries treatment. Lasers have become an alternative to the dental drill in treating teeth with dental caries (decay). Although with larger cavities lasers are somewhat slower than the conventional drill, they truly shine when it comes to early enamel caries and small cavities because they can be quite precise in the amount of tooth structure they remove. This feature allows them to be less invasive than a dental drill.
Periodontal treatment. Periodontal (gum) disease is an infection caused mainly by bacterial plaque and calculus (hardened plaque deposits) that have adhered to tooth surfaces. Lasers are emerging as an alternative to conventional periodontal (gum) surgery to treat voids or spaces below the gum line called periodontal pockets that have formed because of gum tissue detachment as supporting bone is lost. With their ability to target and destroy infected tissue without damaging nearby healthy tissue, lasers can achieve similar outcomes as traditional techniques but with less tissue damage and discomfort to patients afterward.
Research and development into laser technology continues to perfect these and other applications that promise to make dental procedures less invasive and more comfortable for patients.
So you’re tearing up the dance floor at a friend’s wedding, when all of a sudden one of your pals lands an accidental blow to your face — chipping out part of your front tooth, which lands right on the floorboards! Meanwhile, your wife (who is nine months pregnant) is expecting you home in one piece, and you may have to pose for a picture with the baby at any moment. What will you do now?
Take a tip from Prince William of England. According to the British tabloid The Daily Mail, the future king found himself in just this situation in 2013. His solution: Pay a late-night visit to a discreet dentist and get it fixed up — then stay calm and carry on!
Actually, dental emergencies of this type are fairly common. While nobody at the palace is saying exactly what was done for the damaged tooth, there are several ways to remedy this dental dilemma.
If the broken part is relatively small, chances are the tooth can be repaired by bonding with composite resin. In this process, tooth-colored material is used to replace the damaged, chipped or discolored region. Composite resin is a super-strong mixture of plastic and glass components that not only looks quite natural, but bonds tightly to the natural tooth structure. Best of all, the bonding procedure can usually be accomplished in just one visit to the dental office — there’s no lab work involved. And while it won’t last forever, a bonded tooth should hold up well for at least several years with only routine dental care.
If a larger piece of the tooth is broken off and recovered, it is sometimes possible to reattach it via bonding. However, for more serious damage — like a severely fractured or broken tooth — a crown (cap) may be required. In this restoration process, the entire visible portion of the tooth may be capped with a sturdy covering made of porcelain, gold, or porcelain fused to a gold metal alloy.
A crown restoration is more involved than bonding. It begins with making a 3-D model of the damaged tooth and its neighbors. From this model, a tooth replica will be fabricated by a skilled technician; it will match the existing teeth closely and fit into the bite perfectly. Next, the damaged tooth will be prepared, and the crown will be securely attached to it. Crown restorations are strong, lifelike and permanent.
Was the future king “crowned” — or was his tooth bonded? We may never know for sure. But it’s good to know that even if we’ll never be royals, we still have several options for fixing a damaged tooth.
