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.
If you wince in pain while eating or drinking something hot or cold, you’re not alone: tooth sensitivity afflicts one in three Americans. To understand what’s possibly going on, let’s look first at tooth anatomy.
Teeth are mainly composed of three layers: an outer protective enamel that covers the upper crown, a middle layer called dentin and an inner pulp. The dentin is composed of small tubules that transmit outer temperature and pressure sensations to nerves in the pulp.
The enamel serves as a “muffler,” damping sensations to protect the nerves from overload. In the root area, the gums and a thin material called cementum covering the roots also help muffle sensation.
But sometimes teeth can lose this muffling effect and the nerves encounter the full brunt of the sensations. The most common reason is gum recession, usually caused by periodontal (gum) disease. The gums have shrunk back or “receded,” and after a short while the cementum covering will also be lost, exposing the dentin in the root area.
Another problem is enamel erosion caused by mouth acid. Chronic high acidity, often caused by bacterial growth or acidic foods and beverages, can dissolve the enamel’s mineral content, causing decay and exposure as well of the underlying dentin.
To avoid future tooth sensitivity, it pays to prevent these two dental problems. The most important thing you can do is practice daily brushing and flossing to reduce bacterial plaque and see your dentist regularly for dental cleanings and checkups.
But if you’re already experiencing symptoms, you’ll first need an accurate diagnosis of the cause. If it’s related to gum disease, immediate treatment could help stop or even reverse any gum recession. To address enamel erosion, your dentist may be able to protect and strengthen your teeth with sealants and topical fluoride.
There are also things you and your dentist can do to reduce your symptoms. One is for you to use hygiene products with fluoride, which can take the edge off of sensitivity, or potassium, which helps reduce nerve activity. Your dentist can further reduce nerve sensitivity by blocking the tubules with sealants and bonding agents.
Tooth sensitivity is an irritating problem in itself; more importantly, though, it’s often a warning of something else seriously wrong that needs attention. If you’re feeling a little sensitive in the teeth, see your dentist as soon as possible.

Singer and actor Demi Lovato has a new claim to fame: formidable martial artist. When she is not in the recording studio, on stage or in front of the camera, Lovato can often be found keeping in shape at Jay Glazer's Hollywood (California) gym. Glazer, who is best known as a sports journalist, also runs conditioning programs for professional athletes and celebrities based on mixed martial arts. On March 6, Glazer got more than he bargained for when 5'3" Lovato stepped into the ring and knocked out his front tooth.
Glazer reportedly used super glue to put his tooth back together. Not a good idea! While it may not be convenient to drop everything and get to the dental office, it takes an expert to safely treat a damaged tooth. If you glue a broken tooth, you risk having to undergo major work to correct your temporary fix—it's no easy task to "unglue" a tooth, and the chemicals in the glue may damage living tooth tissue as well as the surrounding gum and bone.
Would you know what to do in a dental emergency? Here are some guidelines:
- If you chip a tooth, save the missing piece if possible. We may be able to reattach it.
- If your tooth is cracked, rinse your mouth with warm water, but don't wiggle the tooth around or bite down on it. If it's bleeding, hold clean gauze to the area and call our office.
- If your tooth is knocked loose or is pushed deeper into the socket, don't force the tooth back into position on your own. Immediate attention is very important.
- If your tooth is knocked out, there's a chance it can be reattached. Pick up the tooth while being careful not to touch the root. Then rinse it off and have either someone place into its socket, or place it against the inside of your cheek or in a glass of milk. Please call the office immediately or go to a hospital.
What's the best thing to do in an emergency? Call us right away, and DON'T super glue your tooth! You can prevent worse problems by letting a professional handle any dental issues. And if you've been living with a chipped, broken or missing tooth, call us to schedule an appointment for a consultation—there are several perfectly safe ways to restore your smile. Meanwhile, if you practice martial arts to keep in shape, think twice before getting into the ring with Demi Lovato!
