More than 20 million people in the United States use electronic cigarettes or e-cigs as an alternative to tobacco smoking. While many users believe "vaping" is a healthier alternative to regular cigarettes, recent research into the health effects of e-cigs could put a damper on that belief. There's particular concern among dentists that this popular habit could harm users' dental health.
E-cigs are made with a chamber that holds the liquid vaping solution and a heating mechanism to heat the liquid and vaporize it. Users inhale the vapor, which contains nicotine and flavorings, as they would a traditional cigarette.
The nicotine alone can be problematic for dental health as we'll see in a moment. But the vapor also contains aerosols that some research indicates could damage the inner skin linings of the mouth in a similar fashion to the smoke of traditional cigarettes. One study by researchers with the Université Laval in Quebec, Canada found evidence that e-cig vapor increased the death rate of mouth cells, and led to greater cell irregularities over time.
According to other studies, there's evidence that e-cig vapor may disrupt the balance of the oral microbiome, the communities of both beneficial and harmful bacteria that normally live in the mouth. The imbalance in favor of more harmful bacteria could increase the risk for dental disease, particularly periodontal (gum) disease.
Finally, nicotine from e-cigs seemed to create similar conditions in the mouth as it does with tobacco. Nicotine in any form can constrict blood vessels and reduce the body's ability to fight infection and to heal. Research indicates both forms of nicotine increase the risk for dental disease and make treatment more difficult.
These findings only identify conditions created by e-cigs that could be problematic for future dental health. Although we don't fully understand the long-term health effects of this new habit, based on the evidence so far the mouth may not fare so well. It's looking like e-cigs may be no safer for your teeth and gums than the cigarettes they replace.
April is National Stress Awareness Month. But what does stress have to do with dentistry? According to the American Academy of Sleep Medicine, if you have a Type A personality or are under a lot of stress, you are more likely to suffer from a condition called bruxism, which means you habitually grind or gnash your teeth. One in ten adults grind their teeth, and the rate is much higher in stressful professions. In fact, the bruxism rate is seven times higher among police officers!
Many people grind their teeth in their sleep without realizing it, so how would you know if you are a "sleep bruxer"? If your spouse frequently elbows you in the ribs because of the grinding sounds you make, that could be your first clue. Unfortunately, dental damage is another common sign. Some people find out they are nighttime teeth grinders only when they are examined by a dentist since bruxing often leads to wear patterns on the teeth that only happen because of this behavior. Other complications can also develop: The condition can interfere with sleep, result in headaches and cause soreness in the face, neck or jaw. Chronic or severe nighttime teeth grinding can damage dental work, such as veneers, bridgework, crowns and fillings, and can result in teeth that are worn down, chipped, fractured or loose.
The most common treatment is a custom-made night guard made of high-impact plastic that allows you to sleep while preventing your upper and lower teeth from coming into contact. Although a night guard will protect your teeth and dental work, it won't stop the grinding behavior. Therefore, finding and treating the cause should be a priority.
The Bruxism Association estimates that 70 percent of teeth grinding behavior is related to stress. If you are a bruxer, you can try muscle relaxation exercises, stretching and breathing exercises, stress reduction techniques and, where feasible, any lifestyle changes that can allow you to reduce the number of stressors in your life. Prescription muscle relaxants may also help. In addition, teeth grinding may be related to sleep apnea. This possibility should be investigated since sleep apnea can have some serious health consequences—we offer effective treatments for this condition as well.
We can spot signs of bruxism, so it's important to come in for regular dental checkups. We look for early indications of dental damage and can help you protect your smile. If you have questions about teeth grinding or would like to discuss possible symptoms, please contact our office or schedule an appointment for a consultation.

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.
