Drilling teeth is an essential part of repairing and restoring the damage caused by tooth decay. For generations dentists have relied on the dental drill with its rotating burr to remove decayed and damaged tooth material.
But while the dental drill is effective it also has its disadvantages. In the process of removing decayed material it inadvertently removes healthy structure near the target material. It often requires anesthesia to deaden the work area. And its noise and vibration are often unsettling to patients.
There is a growing alternative, though: air abrasion, a technology that's been around since the mid-20th Century. But recent advances in controlling the dust created by using abrasion, as well as new tooth-colored bonding materials to replace tooth structure, have sparked new interest among dentists and patients alike.
Also known as particle abrasion, this drill alternative uses a pressurized stream of fine particles to remove decayed material. Using a hand wand a dentist can precisely aim the stream of particles (usually aluminum oxide) to the specific areas of decay or softened material that need to be removed. As a result, it removes only a fraction of healthy tooth structure compared to traditional drilling. Air abrasion has also proven effective for removing staining without harming enamel.
Air abrasion also eliminates the sound and vibration associated with dental drills, and may not always require local anesthesia. On the other hand, it does have some limitations. For one, it's not as effective with larger cavities or working around older fillings. The tooth or teeth to be worked on must be carefully isolated from the rest of the mouth to keep the patient from swallowing the abrasive particles. And without a high-volume suction pump and good isolation protocols, the particles can produce something of a “sandstorm” in the treatment room.
But as air abrasion continues to advance, we may see improvements in these limitations. In a future time, the traditional dental drill may go the way of the horse and buggy.

Your teeth were meant to shine! Tooth enamel’s polished translucence, framed by the dentin layer beneath it, has a way of vibrantly catching the light when you smile. But tooth wear and structural changes as you age can dim that shine. Add to that staining caused by foods and beverages or disease and your smile could further lose its luster.
On your supermarket or pharmacy oral hygiene aisle you’ll find dozens of products promising to restore that lost luster, including toothpastes, whitening kits or even chewing gum. While such products work to some degree, our dental office may have the right solution for you: a safe and effective treatment for whitening teeth.
Why see us for teeth whitening? For one, professional whitening solutions contain a higher concentration of bleaching agent (usually 35-45% hydrogen peroxide) than home kits. We usually apply it in a gel form directly to the teeth while using barrier devices like dams to protect the lips and other soft tissue from irritation. We may then apply heat or light to the applied gel to enhance the release of peroxide into your enamel.
This professional procedure can often give you a brighter smile in fewer sessions than a home whitening kit — and it may last longer. What’s more, we can control the level of brightness to produce only a subtle change or a dazzling “Hollywood” smile — whatever your preference.
Like a home kit, this procedure bleaches staining on the outer surface of enamel, known as extrinsic staining. But you can also have discoloration deep within a tooth, known as intrinsic staining, caused by a variety of reasons like tetracycline use early in life or complications from a root canal treatment. Home kits or even the professional treatment described above can’t whiten intrinsic staining.
For intrinsic staining you’ll need a special procedure that places a bleaching agent inside the tooth. Depending on the extent of staining the procedure could require more than one session.
To find out what kind of discoloration you have, visit us for a full examination. We’ll then be able to give you your options for putting the shine back in your smile.

Humanity has been waging war against tooth decay for millennia — with this relentless opponent often getting the better of us.
Over the last century, however, significant treatment advances have turned the tide of battle in our favor. Perhaps the greatest of these advancements is our deeper grasp of the disease process — new understandings that have altered our treatment strategy. Rather than wait for cavities to occur and then repair the damage, we now focus on stopping the damage from occurring in the first place.
Prevention starts by reducing factors that contribute to tooth decay. We can signify these detrimental factors with the acronym BAD:
Bad Bacteria. Millions of bacteria inhabit our mouths at any one time, but only a few strains produce the acid that causes decay. We want to reduce their population by removing dental plaque (where they feed and grow) through daily brushing and flossing, and, at a minimum, semi-annual office cleanings.
Absence of Saliva. This important fluid neutralizes acid and strengthens tooth enamel. Some people, however, suffer from reduced saliva flow. We want to find the cause (for example, a side effect of certain prescription drugs) and then improve saliva flow.
Dietary Habits. A diet heavy in sugar and acid (particularly sodas and soft drinks) gives bacteria a ready food source and increases the mouth’s acidic level. Chronic high acid levels in particular are often too great for normal saliva flow to overcome and neutralize. Reducing the amount and frequency of these food items creates a healthier oral environment.
Reducing BAD factors is only half of our prevention focus. We also want to promote SAFE factors that enhance tooth health and strength: Sealants, especially for children, that shield tooth surfaces from decay; Antimicrobial rinses that target and rid the mouth of acid-producing bacteria and give healthy bacteria room to develop; Fluoride, a proven enamel-strengthening chemical available in dental products, many drinking water systems and as a topical application in dental offices; and an Effective diet that’s rich in nutrients and low in sugar and acid as already mentioned.
Keeping the focus on reducing BAD factors and promoting SAFE factors will greatly increase your chances of personally winning the war against tooth decay.
