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.
If your teenager is in need of orthodontic treatment, you might automatically think braces. But while this decades-old appliance is quite effective, it isn’t the only “tooth movement” game in town any more. Clear aligners are another choice your teenager might find more appealing.
Clear aligners are a sequential set of computer-generated plastic trays that are worn by a patient one after the other, usually for about two weeks per tray. The trays are fabricated using 3-D computer modeling of the patient’s mouth, each one slightly different from the last to gradually move teeth to the desired new positions.
So, why choose clear aligners over braces?
They’re nearly invisible. Because they’re made of a clear polymer material, they’re not nearly as noticeable as metal braces. In fact, they may go completely unnoticed to the casual observer.
They’re removable. Unlike metal braces, which are fixed in place by an orthodontist, clear aligners can be removed by the wearer. This makes brushing and flossing much easier, and they can also be removed for eating or special occasions. That said, though, they should be worn at least 20 to 22 hours each day to be effective.
They’re becoming more versatile. With some complicated malocclusions (poor bites), braces and other orthodontic appliances may still be necessary. But innovations like added power ridges in clear aligners can more precisely control which teeth move and which don’t. This has greatly increased the number of poor bite scenarios where we can appropriately use clear aligners.
If you’d like to consider clear aligners, just remember they require a bit more self-discipline on the part of the wearer than braces. And once the treatment finishes, they’ll still need to wear a retainer just as with metal braces to help keep the repositioned teeth from reverting to their old positions.
If you think your teen is up to the challenge and their particular situation can be corrected with this innovative technology, then clear aligners could be a great choice.

Many people consider a root canal treatment to be potentially an unpleasant experience. You might even feel a few butterflies fluttering in your stomach if we were to recommend one for you.
But there’s nothing actually to dread about this common and very effective treatment. The procedure doesn’t cause pain; in fact, it most likely relieves tooth pain. What’s more, it could save a tooth that would be otherwise lost.
The name comes from narrow passageways extending from the tip of the root to the innermost tooth pulp. The pulp contains nerves and other structures once vital to early tooth development. And although they’re not as important in a fully mature tooth, those nerves still function. In other words, they can still feel stimulation or pain.
That shouldn’t be a problem with a healthy tooth. But if tooth decay invades the inner pulp, those nerves now under attack will begin firing. You’ll know something’s wrong. As bad as it feels, though, the toothache isn’t your worst problem: if the decay isn’t stopped, it can spread through the root canals to the bone that could eventually lead to losing the tooth.
A root canal treatment removes the decayed pulp tissue and protects the tooth from re-infection. We first deaden the tooth and surrounding tissues with a local anesthesia and set up a rubber dam around the tooth to protect it from contamination from the surrounding environment. We then drill a small access hole through the enamel and dentin to reach the pulp chamber and root canals.
Using special instruments, we remove all the diseased tissue from the pulp and flush out the empty chamber and root canals with antibacterial solutions. After re-shaping the root canals, we fill them and the pulp chamber with gutta-percha, a rubber-like biocompatible material that conforms well to the root canal walls. We seal the gutta-percha with adhesive cement and then fill the access hole. Later, we’ll give the tooth further protection with a custom crown.
After the procedure, you may experience short-term minor discomfort usually manageable with over-the-counter pain relievers like ibuprofen. The good news, though, is that the excruciating nerve pain from within the tooth will be gone—and your tooth will have a new lease on life.
