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.

Although primary (“baby”) teeth have a lifespan of only a few years, they’re still important to a child’s current and future dental health. In the present, they help a child eat, speak and smile properly. They also help create a healthy future as placeholders for developing permanent teeth yet to come in.
If, however, a child loses a primary tooth prematurely due to decay, the corresponding permanent tooth could come in misaligned. That’s why we do what we can to help a decayed primary tooth reach its full lifespan. And there are different ways to do this depending on the type of tooth.
With front teeth, which don’t encounter the same chewing forces as those in the back, we may use a tooth-colored filling. This approach is also preferable for appearance’s sake since front teeth are highly visible when a child speaks or smiles.
Primary molars, on the other hand, need a more robust solution. A filling may not be able to withstand the level of long-term chewing forces that these back teeth normally encounter. And because they’re less visible than front teeth, there’s less concern about aesthetics.
That’s why many pediatric dentists prefer stainless steel crowns for molars. Just like their permanent teeth counterparts, a primary crown fits over and completely covers a tooth. They’re typically pre-formed, coming in different shapes and sizes that can then be customized for the tooth in question. After preparing and removing any decayed material from the tooth, we can usually install the crown in one visit with local anesthesia and a sedative (if the child needs it for anxiety).
While a steel crown isn’t the most attractive restoration, it typically handles the higher chewing forces in the back of the mouth better and longer than a filling. That’s especially critical for primary molars, which are some of the last teeth to fall out (as late as ages 10-12). And besides preserving it as a permanent tooth placeholder, a crown also helps the tooth function effectively in the present.
Regardless of what method we use, though, preserving primary teeth is a primary goal of pediatric dentistry. And with a stainless steel crown, we can keep those important back molars functioning for as long as they’re intended.

While the sport of golf may not look too dangerous from the sidelines, players know it can sometimes lead to mishaps. There are accidents involving golf carts and clubs, painful muscle and back injuries, and even the threat of lightning strikes on the greens. Yet it wasn’t any of these things that caused professional golfer Danielle Kang’s broken tooth on the opening day of the LPGA Singapore tournament.
“I was eating and it broke,” explained Kang. “My dentist told me, I've chipped another one before, and he said, you don't break it at that moment. It's been broken and it just chips off.” Fortunately, the winner of the 2017 Women’s PGA championship got immediate dental treatment, and went right back on the course to play a solid round, shooting 68.
Kang’s unlucky “chip shot” is far from a rare occurrence. In fact, chipped, fractured and broken teeth are among the most common dental injuries. The cause can be crunching too hard on a piece of ice or hard candy, a sudden accident or a blow to the face, or a tooth that’s weakened by decay or repetitive stress from a habit like nail biting. Feeling a broken tooth in your mouth can cause surprise and worry—but luckily, dentists have many ways of restoring the tooth’s appearance and function.
Exactly how a broken tooth is treated depends on how much of its structure is missing, and whether the soft tissue deep inside of it has been compromised. When a fracture exposes the tooth’s soft pulp it can easily become infected, which may lead to serious problems. In this situation, a root canal or extraction will likely be needed. This involves carefully removing the infected pulp tissue and disinfecting and sealing the “canals” (hollow spaces inside the tooth) to prevent further infection. The tooth can then be restored, often with a crown (cap) to replace the entire visible part. A timely root canal procedure can often save a tooth that would otherwise need to be extracted (removed).
For less serious chips, dental veneers may be an option. Made of durable and lifelike porcelain, veneers are translucent shells that go over the front surfaces of teeth. They can cover minor to moderate chips and cracks, and even correct size and spacing irregularities and discoloration. Veneers can be custom-made in a dental laboratory from a model of your teeth, and are cemented to teeth for a long-lasting and natural-looking restoration.
Minor chips can often be remedied via dental bonding. Here, layers of tooth-colored resin are applied to the surfaces being restored. The resin is shaped to fill in the missing structure and hardened by a special light. While not as long-lasting as other restoration methods, bonding is a relatively simple and inexpensive technique that can often be completed in just one office visit.

Today's dental restorations are truly amazing. Not only are they life-like and functional, they can endure for many years a hostile environment of bacteria, acid and heavy biting forces.
Even so, you'll still need to take care of your restorations to help them last. Here's how to extend the life of 3 common forms of dental work.
Fillings. We use fillings, both metal amalgam and tooth-colored materials, to repair holes or cavities in teeth caused by tooth decay. Although strong, dental fillings can break if you subject them to abnormally high biting force (like chewing ice). There's also a chance that if a slight separation occurs between the filling and tooth, bacteria can take up residence and reignite the decay process. To prevent this, practice a daily regimen of oral hygiene to clean away bacterial plaque—and reduce sugar in your diet, a prime food source for bacteria.
Veneers. Usually made of thin porcelain, veneers are bonded to the front of teeth to mask chips, stains, gaps or other blemishes. But although they're strong, veneers aren't immune to damage. Habits like biting nails, the aforementioned ice chewing or unconsciously grinding your teeth could cause a chipped veneer. And if periodontal (gum) disease causes your gums to recede, the exposed part of the tooth may look noticeably darker than the veneer. To protect your veneers and their appearance, avoid habits like ice chewing, and seek treatment for teeth grinding and dental disease.
Bridgework. Bridges are used to replace one or more missing teeth. Traditional bridges use the natural teeth on either side of the gap to support the bridge; for a single missing tooth, implants are a preferable option because they don't require permanently altering the neighboring teeth to support it. With either option, though, you should brush and floss around the restoration to reduce the risk of dental disease. Infections like gum disease or tooth decay could eventually weaken the bridge's supporting teeth or gum disease can damage an implant's gum and bone support.
With any dental restoration, be sure to practice daily oral hygiene, eat a nutritious, low-sugar diet, and see your dentist regularly for cleanings and checkups. Taking care of your dental work will help it take care of you for a long time to come.
If you notice a small sore or a change in the appearance of the tissues inside your mouth, don’t panic. It’s likely a common, minor ailment that appears on a lot of skin surfaces (like the wrists or legs) besides the cheeks, gums, or tongue.
These small sores or lesions are called lichen planus, named so because their coloration and patterns (white, lacy lines) look a lot like lichen that grow on trees or rocks. They’re only similar in appearance to the algae or fungi growing in the forest — these are lesions thought to be a form of auto-immune disease. Although they can affect anyone, they’re more common in women than men and with middle-aged or older people.
Most people aren’t even aware they have the condition, although some can produce itching or mild discomfort. They’re often discovered during dental checkups, and although they’re usually benign, we’ll often consider a biopsy of them to make sure the lesion isn’t a symptom of something more serious.
There currently isn’t a cure for the condition, but it can be managed to reduce symptoms; for most people, the lesions will go away on their own. You may need to avoid spicy or acidic foods like citrus, tomatoes, hot peppers or caffeinated drinks that tend to worsen the symptoms. If chronic stress is a problem, finding ways to reduce it can also help alleviate symptoms as well as quitting tobacco and reducing your alcohol intake.
Our biggest concern is to first assure the lesion isn’t cancerous. Even after confirming it’s not, we still want to keep a close eye on the lesion, so regular monitoring is a good precaution. Just keep up with the basics — good oral hygiene and regular checkups — to ensure you have the most optimum oral health possible.
