Tooth enamel erosion is a serious issue for many children that can result in permanent impairment of oral health. The problem isn’t just bacterial acid that causes tooth decay — it’s also the high acid content of sodas, energy and sports drinks widely popular among children and teenagers today.
Enamel is made of the strongest substance in the human body, which enables it to shield the inner layers of the teeth from disease and other environmental factors. Its chief nemesis, though, is acid: when enamel interacts with high concentrations of acid for a prolonged time, its mineral content will begin to soften and dissolve, a process known as de-mineralization. Saliva is the enamel’s main protection against acid with the ability to neutralize (or buffer) acid and restore some of the enamel’s mineral content, usually within thirty minutes to an hour after we eat.
The high acid content of many popular beverages, however, can overwhelm saliva’s buffering ability, especially if a person is sipping for an extended time on an acidic drink. This kind of exposure is different from acid produced by bacteria that causes tooth decay: bacterial acid tends to concentrate in specific areas of the teeth, while the constant wash from acidic beverages will have a more generalized eroding effect on teeth.
This level of enamel loss is irreversible, which can leave a tooth in peril of decay and ultimate loss — and increase long-term dental care and costs. The best strategy is to have your child stop or significantly curtail drinking highly acidic beverages. Rather than drink sports beverages for hydration, substitute water, nature’s hydrator. Milk can also be a viable beverage substitute.
If you do allow some acidic beverages, try to limit them to mealtimes and discourage extended sipping. Look for drinks with added calcium as this can reduce the beverage’s erosive potential. The goal is to reduce the amount and duration beverage acid is in contact with tooth enamel.
Making these changes will help greatly to protect your child’s tooth enamel, and give saliva a chance to do its job protecting it. Your efforts will also increase your child’s chances of better dental health in the future.

Compared to other dental restorations—a few of which have been around for over a century—implants are a relatively recent development. But even though it's just now entering its fourth decade, recent advances have catapulted implant therapy well beyond where it began.
That's due mainly to digital technology. Two examples of this, computed tomography (CT) and 3-D printing, are increasing the accuracy and efficiency of implant placement.
Properly placing an implant is one of the most important elements in achieving a natural and attractive result. But finding the best location is often difficult due to a lack of suitable bone volume, the patient's bite or the proximity of anatomical structures like nerves and blood vessels. CT imaging, especially Cone Beam CT scanners (CBCT), is helping to make implant placement planning easier.
Unlike the static, two-dimensional views of standard x-rays, CBCT takes hundreds of images and digitally blends them together to create a virtual 3-D model of the patient's jaw and face. Dentists can view this highly detailed model on a computer monitor from various vantage points and better identify possible obstructions. With better information about what "lies beneath," they can more accurately pinpoint the best implant site.
Creating the ideal plan is one thing—successfully implementing it is another. Dentists often create a surgical guide that helps them drill in precisely the right positions during surgery. The guide, which resembles a mouthguard, fits over the gums and contains marker locations for drilling.
Many dentists are now using 3-D printing to create these surgical guides. A 3-D printer turns a digital model of the guide based on measurements of the patient's mouth and proposed implant locations into an actual physical object "printed out" layer by layer of special polymer material. The end product can be more precise than guides created by other means.
These and other technological developments are helping implant therapy rise to a new level of success. With the resulting increase in accuracy, efficiency and less treatment time, tomorrow's implant patients will be the ultimate beneficiaries.

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.
