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.

Unlike the months on either side, August isn't known for major holidays. But it does have one cause for celebration: National Fresh Breath Day! True, this observance will probably never achieve big-time recognition. Yet everyone would agree that fresh breath is something to appreciate! Unfortunately, bad breath is a persistent problem for many people. The first step in treating it is to identify the cause. Here are 5 common causes of bad breath:
1. Poor oral hygiene. Certain types of oral bacteria cause bad breath, and the mouth provides a perfect environment for them—especially when dental plaque and food debris is not well cleansed. So to keep your breath fresh, maintain a diligent oral hygiene routine. This includes brushing your teeth twice a day with fluoride toothpaste and flossing at least once a day. For an extra-clean mouth, use a tongue scraper—a plastic tool about the size of a toothbrush that's available in most drug stores. This will remove bacteria and food debris from your tongue for extra freshness.
2. Oral diseases. Bad odors in your mouth may also be caused by infections—which is what tooth decay and gum disease actually are. Sometimes old fillings wear out, allowing bacteria to re-infect a tooth that was once treated for decay. Other signs of these common oral diseases include tooth pain and bleeding or puffy gums. If you notice any of these, don't ignore it—make a dental appointment today!
3. Diet. Smelly foods will give you smelly breath; it's that simple. And the odors may linger after you have eaten them. When onion, garlic and other pungent foods are digested, their odor-producing substances enter your bloodstream and proceed to your lungs—which can affect how your breath smells. If you suspect your dietary habits are causing bad breath, try eliminating certain foods (at least temporarily) and see if that helps.
4. Dry mouth. Saliva helps cleanse your mouth, so reduced saliva flow can lead to bad breath. This accounts for "morning breath," which is caused when the mouth dries out during sleep (especially if you are a mouth-breather). However, some people don't produce enough saliva throughout the day. Sometimes it's just that they don't drink enough water. But a very common cause of chronic dry mouth is regular use of medications, both prescription and over-the-counter. If you notice that medication is drying out your mouth, let your doctor know. And stay hydrated!
5. Smoking. Given that smoking increases your risk for many serious diseases, including oral cancer, the fact that it can lead to bad breath seems almost trivial. Still, it's worth noting that smoking causes mouth odor both directly and indirectly by reducing the flow of saliva and promoting gum disease. In fact, tobacco in all forms is a hazard to your health.

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.
