When planning for your new smile, we look at more than the condition of individual teeth. We also step back for the bigger “bite” picture: how do the teeth look and interact with each other?
If we have a normal bite, our teeth are aligned symmetrically with each other. This not only looks aesthetically pleasing with the rest of the face, it also contributes to good function when we chew food. A bad bite (malocclusion) disrupts this mouth-to-face symmetry, impairs chewing and makes hygiene and disease prevention much more difficult.
That's where orthodontics, the dental specialty for moving teeth, can work wonders. With today's advanced techniques, we can correct even the most complex malocclusions — and at any age. Even if your teen years are well behind you, repairing a bad bite can improve both your smile and your dental health.
The most common approach, of course, is braces. They consist of metal or plastic brackets bonded to the outside face of the teeth with a thin metal wire laced through them. The wire attaches to an anchorage point, the back teeth or one created with other appliances, and placed under tension or pressure. The gradual increasing of tension or pressure on the teeth will move them over time.
Â Braces are versatile and quite effective, but they can be restrictive and highly noticeable. Many people, especially older adults, feel embarrassed to wear them. There is an alternative: clear aligners. These are a series of clear, plastic trays that you wear in sequence, a couple of weeks for each tray. When you change to the next tray in the series, it will be slightly different than its predecessor. As the trays change shape guided by computer-enhanced modeling, the teeth gradually move.
If you're interested in having a poor bite corrected, the first step is a comprehensive orthodontic examination. This looks closely at not only teeth position, but also jaw function and overall oral and general health.
With that we can help you decide if orthodontics is right for you. If so, we'll formulate a treatment plan that can transform your smile and boost your dental health.

While it may not be one of your favorite features in the dental office, the dental drill is nevertheless necessary for treating problem teeth. It’s used primarily for removing decayed or damaged structure and preparing a tooth for fillings or other restorations.
Dental drills have been used for decades and are quite effective — but they have their drawbacks. Their rotating burrs often remove portions of healthy tooth structure along with decayed material. Friction from the drill action can cause discomfort, so local anesthesia is usually needed. Drills can also emit a high-pitched machine noise that’s unsettling to many patients.
There’s a growing alternative to the drill, known as air abrasion. Although the technology has been around since the 1950s, the development of new suction pumps that capture the resulting dust from its use has made it more palatable as an option to the traditional drill.
Also known as particle abrasion, the technique uses a pressurized stream of fine particles (usually aluminum oxide, an abrasive powder) directed at teeth to wear away (abrade) the tooth’s structural surface. We can be quite precise in the amount of surface material removed, so it’s useful for diminishing stains or roughing the surface for bonding materials like composite resin. We’re also able to remove decayed material with very little impact on surrounding healthy structure, and you may not need anesthesia during the procedure.
While this quiet alternative to the noisier drill is quite versatile, it does have its limitations. It’s not that efficient for preparing larger cavities for restoration or for removing older amalgam fillings. The teeth to be treated must be carefully isolated to prevent the fine particle dust produced from being swallowed by the patient or spread into the air. High-volume suction equipment is a must or the procedure will create a “sandstorm” of particles in the room.
Still, for situations suited to it and with proper isolation measures, air abrasion can be effective and comfortable. If the technology continues to improve, the dental drill may soon become a relic of the past.
