If you think “vaping” electronic cigarettes (e-cigarettes for short) is healthier for your teeth and gums than smoking cigarettes, you might be disappointed with the latest research. A number of studies seem to indicate e-cigarettes could be just as damaging to your mouth as traditional cigarettes.
An e-cigarette is a device containing a chamber for liquids and a means to heat the liquid into a vapor. The user then inhales or “vapes” the vapor, which contains nicotine and flavorings. The heat also pressurizes the vapor causing it to expel as an aerosol into the mouth.
Researchers have found the ingredients and aerosol effect could lead to potential health problems. An Ohio State University researcher found that vaping disrupted the normal balance of microorganisms in the mouth known as the oral microbiome. This imbalance could make it easier for disease-causing bacteria to proliferate, particularly those most responsible for periodontal (gum) disease.
Another study coming out of the University of Rochester and Stony Brook University in New York detected cell damage in gum tissue caused by e-cigarette vapor similar to that caused by regular cigarette smoke. Some of this damage seemed to result from the flavoring agents used in the e-cigarette liquid, as well as nicotine.
Another study from Quebec, Canada appears to concur with the New York study. These researchers found the damage caused by e-cigarette vapor might substantially increase the rate of cell death in oral tissues by as much as 50% over a short period of time. This kind of damage can lead to higher risks of dental diseases like gum disease or tooth decay.
While we don’t know the long-term effect of using e-cigarettes on both oral and general health, these studies are alarming: They seem to show vaping may cause some of the same problems as smoking. With the jury still out, the prudent thing to do is limit or avoid vaping altogether to protect your mouth from these unhealthy outcomes.
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.

In many parts of the country, summer is often a synonym for "blast furnace" and can be downright hot and miserable. If you find yourself in such a climate, it's imperative that you drink plenty of water to beat both the heat and heat-related injuries. Your teeth and gums are another reason to keep hydrated during those hot summer months.
Your body needs water to produce all that saliva swishing around in your mouth. When you have less water available in your system, the production of this important bodily fluid can go down—and this can increase your risk of dental disease. That's because saliva performs a number of tasks that enhance dental health. It helps rinse the mouth of excess food particles after eating that could become a prime food source for disease-causing bacteria. It also contains antibodies that serve as the first line of defense against harmful microorganisms entering through the mouth.
Perhaps saliva's most important role, though, is protecting and strengthening enamel, the teeth's outer "armor" against disease. Although the strongest substance in the body, enamel has one principal foe: oral acid. If the mouth's normally neutral pH becomes too acidic, the minerals in enamel begin to soften and dissolve. In response, saliva neutralizes acid and re-mineralizes softened enamel.
Without a healthy salivary flow protecting the mouth in these different ways, the teeth and gums are vulnerable to assault from bacteria and acid. As they gain the upper hand, the risk for tooth decay or periodontal (gum) disease can skyrocket. Keeping yourself adequately hydrated ensures your body can produce an ample flow of saliva.
By the way, summer heat isn't the only cause for reduced saliva: Certain prescription medications may also interfere with its production. Chemotherapy and radiation, if targeting cancer near the head or neck, can damage salivary glands and impact flow as well.
If you have reduced saliva from medication you're taking, talk to your doctor about switching to an alternative prescription that doesn't affect saliva production. If you're undergoing cancer treatment, be extra vigilant about your oral hygiene practice and regular dental visits. And as with summer heat, be sure you're drinking plenty of water to help offset these other effects.
Even when it's hot, summertime should be a time for fun and relaxation. Don't let the heat ruin it—for your health or your smile.
