While you may most associate professional dental cleanings with that “squeaky” clean feeling you have afterward, there is a much higher goal. What is also referred to as “non-surgical periodontal therapy,” these cleanings seek to remove bacterial plaque and tartar (hard deposits) not only from the visible portions of the tooth but also the root surfaces (scaling), so as to reduce the risk and occurrence of periodontal gum disease.
For generations, this was primarily achieved by dental hygienists using hand-held instruments specially designed to manually remove plaque from tooth surfaces. Since the 1950s, though, a new technology known as ultrasonic or power scaling has become more prevalent in use. Initially only used in the outer most portions of the gum tissue (the supra-gingival area) power scaling is increasingly employed to clean the sub-gingival area, much closer to the tooth roots. As this technology has developed, it’s been shown to be just as effective, if not superior in some cases, to manual scaling for removing plaque and tartar.
Ultrasonic or power scalers work by emitting high vibration energy that crushes and removes plaque and calculus (tartar). The resulting shockwaves also tend to disrupt bacterial cell function. The hygienist uses water to flush away the dislodged calculus. They have a number of advantages over manual scaling: they’re quite effective on deep gum pockets, especially when specially designed tips are used; they require less time than manual scaling; and when used correctly power scalers are gentler to tooth structures.
However, they do have a few drawbacks. Because they produce an aerosol effect, power scalers can project contaminants from the patient’s mouth into the atmosphere, requiring special protective equipment for the hygienist. They’re not recommended for patients with hypersensitive teeth, especially regarding temperature change, or for teeth with areas of de-mineralization (the loss of mineral content in the enamel). Care should be taken when they’re used with implants or porcelain or composite crowns — specially designed tips are necessary to avoid scratching the restoration. They may also have an effect on cardiac pacemakers.
In the end, the best approach is a combination of both power and manual scaling techniques. Depending on your individual needs, ultrasonic scaling can do an effective job in removing plaque and tartar and help you avoid gum disease.

Let’s say you’re traveling to Italy to surprise your girlfriend, who is competing in an alpine ski race… and when you lower the scarf that’s covering your face, you reveal to the assembled paparazzi that one of your front teeth is missing. What will you do about this dental dilemma?
Sound far-fetched? It recently happened to one of the most recognized figures in sports — Tiger Woods. There’s still some uncertainty about exactly how this tooth was taken out: Was it a collision with a cameraman, as Woods’ agent reported… or did Woods already have some problems with the tooth, as others have speculated? We still don’t know for sure, but the big question is: What happens next?
Fortunately, contemporary dentistry offers several good solutions for the problem of missing teeth. Which one is best? It depends on each individual’s particular situation.
Let’s say that the visible part of the tooth (the crown) has been damaged by a dental trauma (such as a collision or a blow to the face), but the tooth still has healthy roots. In this case, it’s often possible to keep the roots and replace the tooth above the gum line with a crown restoration (also called a cap). Crowns are generally made to order in a dental lab, and are placed on a prepared tooth in a procedure that requires two office visits: one to prepare the tooth for restoration and to make a model of the mouth and the second to place the custom-manufactured crown and complete the restoration. However, in some cases, crowns can be made on special machinery right in the dental office, and placed during the same visit.
But what happens if the root isn’t viable — for example, if the tooth is deeply fractured, or completely knocked out and unable to be successfully re-implanted?
In that case, a dental implant is probably the best option for tooth replacement. An implant consists of a screw-like post of titanium metal that is inserted into the jawbone during a minor surgical procedure. Titanium has a unique property: It can fuse with living bone tissue, allowing it to act as a secure anchor for the replacement tooth system. The crown of the implant is similar to the one mentioned above, except that it’s made to attach to the titanium implant instead of the natural tooth.
Dental implants look, function and “feel” just like natural teeth — and with proper care, they can last a lifetime. Although they may be initially expensive, their quality and longevity makes them a good value over the long term. A less-costly alternative is traditional bridgework — but this method requires some dental work on the adjacent, healthy teeth; plus, it isn’t expected to last as long as an implant, and it may make the teeth more prone to problems down the road.
What will the acclaimed golfer do? No doubt Tiger’s dentist will help him make the right tooth-replacement decision.
