Root canal treatments are an essential part of dental care — countless teeth with deep decay would be lost each year without it. Now, this traditional dental care procedure is advancing to a new level of precision through lasers.
Root canal treatments have a simple goal: access a tooth's infected pulp and root canals, clean out the infected tissue and fill the empty pulp chamber and canals with a special filling. Once filled, the access is sealed and a porcelain crown later placed for additional protection against re-infection.
In the traditional procedure, we perform these steps manually with a dental drill and hand instruments. We may also need to remove a good portion of tooth structure, both healthy and infected tissue. A laser, on the other hand, is a highly focused beam of light with the ability to interact with healthy and infected tissues differently: destroying infected tissue while having no effect on nearby healthy tissue. The end result: we may be able to remove less healthy tissue with lasers than with the conventional procedure.
Lasers are also helpful with softening and precisely molding the filling material within each canal's particular shape. And, early reports seem to indicate a higher degree of comfort for patients (less drill noise and need for anesthesia), less bleeding and faster recovery times than the conventional approach.
But as a tool for root canal treatments, lasers do have a couple of disadvantages. While light travels in a straight line, root canals are rarely straight — conventional instruments with curved designs usually accommodate odd canal shapes better than a laser. Lasers can also raise temperatures within a tooth that can damage healthy tissue, both within the pulp and outward into the dentin.
Still, lasers for root canal treatments appear promising with some dentists using a combination of lasers and manual techniques to garner benefits from both approaches. While you won't see lasers replacing the traditional root canal treatment anytime soon, the future looks bright for more efficient ways to treat deep tooth decay.
You probably wouldn't be surprised to hear that someone playing hockey, racing motocross or duking it out in an ultimate fighter match had a tooth knocked out. But acting in a movie? That's exactly what happened to Howie Mandel, well-known comedian and host of TV's America's Got Talent and Deal or No Deal. And not just any tooth, but one of his upper front teeth—with the other one heavily damaged in the process.
The accident occurred during the 1987 filming of Walk Like a Man in which Mandel played a young man raised by wolves. In one scene, a co-star was supposed to yank a bone from Howie's mouth. The actor, however, pulled the bone a second too early while Howie still had it clamped between his teeth. Mandel says you can see the tooth fly out of his mouth in the movie.
But trooper that he is, Mandel immediately had two crowns placed to restore the damaged teeth and went back to filming. The restoration was a good one, and all was well with his smile for the next few decades.
Until, that is, he began to notice a peculiar discoloration pattern. Years of coffee drinking had stained his other natural teeth, but not the two prosthetic (“false”) crowns in the middle of his smile. The two crowns, bright as ever, stuck out prominently from the rest of his teeth, giving him a distinctive look: “I looked like Bugs Bunny,” Mandel told Dear Doctor—Dentistry & Oral Health magazine.
His dentist, though, had a solution: dental veneers. These thin wafers of porcelain are bonded to the front of teeth to mask slight imperfections like chipping, gaps or discoloration. Veneers are popular way to get an updated and more attractive smile. Each veneer is custom-shaped and color-matched to the individual tooth so that it blends seamlessly with the rest of the teeth.
One caveat, though: most veneers can look bulky if placed directly on the teeth. To accommodate this, traditional veneers require that some of the enamel be removed from your tooth so that the veneer does not add bulk when it is placed over the front-facing side of your tooth. This permanently alters the tooth and requires it have a restoration from then on.
In many instances, however, a “minimal prep” or “no-prep” veneer may be possible, where, as the names suggest, very little or even none of the tooth's surface needs to be reduced before the veneer is placed. The type of veneer that is recommended for you will depend on the condition of your enamel and the particular flaw you wish to correct.
Many dental patients opt for veneers because they can be used in a variety of cosmetic situations, including upgrades to previous dental work as Howie Mandel experienced. So if slight imperfections are putting a damper on your smile, veneers could be the answer.

Think dental implants only replace individual teeth? Think again—this premier technology can also support other kinds of restorations to provide better stability and comfort. And, they also help improve bone health when incorporated with any type of tooth replacement options, especially dentures.
Although traditional dentures have enjoyed a long, successful history as a tooth replacement solution, they can interfere with bone health. That’s because regular dentures fit in the mouth by resting on the bony ridges of the jaw, which has implications for the bone.
As living tissue, bone goes through a growth cycle with older bone cells dying and dissolving and newer cells forming to take their place. The teeth play a role in this growth cycle — the forces generated when we chew travel up through the teeth and help stimulate bone growth. When teeth go missing, however, so does this stimulus.
Traditional dentures can’t replace this missing stimulus. In fact, the constant pressure of dentures on the jaw may even accelerate bone loss. A sign this is happening occurs when the dentures’ once tight fit begins to loosen and they become uncomfortable to wear.
Implant-supported dentures can help eliminate this problem. We first surgically place a few implants in the jaw, the number determined by which jaw (the lower requires less) and whether the denture is removable or fixed. If removable, the denture has connective points that match the implant locations — you simply connect them with the implants. If fixed, the denture is screwed into the implants to hold it in place.
So, how does this help bone health? For one, the denture no longer puts as much pressure on the jaw ridges—the main support comes from the implants. And, the implants themselves encourage bone stimulation: The titanium in the implant has a special affinity with bone cells that naturally grow and adhere to its metal surface. This natural integration between implant and bone can stop bone loss and may even help reverse it.
If you’re interested in implant-supported dentures, you’ll first need to undergo a full dental exam with your dentist. These restorations aren’t appropriate for all dental situations. But, if they can work for you, you may be able to enjoy the benefits of an implant-supported restoration.
