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.
Teenagers and adults alike can improve their smile appearance with dental solutions like teeth whitening or orthodontics. But there are a few cosmetic solutions like porcelain veneers that are better suited for more mature teeth.
Veneers are composed of thin layers of dental porcelain that are bonded to the outside of teeth. They're kind of a tooth "mask" that hides blemishes like chips, discoloration or mild bite problems. They're often less involved and expensive than other types of dental restoration.
Even so, we usually need to remove some of the natural tooth's enamel before applying them. Veneers placed directly on unprepared teeth can appear bulky, so we remove some of the enamel to create a more natural look. And although usually only a slight amount, the alteration is permanent and will require the tooth to have some form of restoration from then on.
This usually doesn't pose a major issue for adults, but it could for a teenager's younger teeth. The nerve-filled dentin in a teenager's still developing tooth is thinner and closer to the pulp (nerve tissue) than in more mature teeth.
There's at least one situation, though, where veneers might be applied safely to a teenager's teeth without this concern. If the teen has abnormally small teeth and are receiving veneers to improve their appearance, they might not need alteration. Because the teeth are already thinner than normal, the "no-prep" veneers may not look bulky when directly bonded to them without preparation.
With most cases, though, it might be best to pursue other options that at the very least can make a cosmetic difference until their teeth are mature enough for veneers. For example, we might be able to repair chipped areas with composite resin material that we form and bond to the tooth to achieve a life-like appearance.
We can discuss these and other options for safely improving your teenager's smile. The important thing is to achieve a more confident appearance without endangering their future 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.
