Poor bites, also known as “malocclusions,” can have a dramatic impact on mouth function and appearance. Moving teeth to better positions will solve most of these bite problems — but not all.
A case in point is a malformed maxilla, the skeletal structure formed by the union of the upper jaw and the roof of the mouth (the palate). If the rear portion of the maxilla develops too narrowly, the back teeth will bite abnormally inside the lower teeth while the front teeth bite normally, creating what’s known as a crossbite. People with this kind of malocclusion often shift their lower jaw to one side to bite down completely.
This can be corrected without too much intervention if the problem is diagnosed while the person is young. This is because the maxilla is actually formed from two bones that don’t completely fuse together in the center of the palate until just after puberty. An orthodontic appliance known as a palatal expander takes advantage of this slight gap. The metal appliance is placed along the narrowed portion of the palate in the rear of the mouth: four metal “arms,” two on each side, attach to the inside of the back teeth with a tension device between them that extends the arms outward to put pressure against the teeth.
Every day the patient or a parent uses a special key to turn the tension device and cause it to expand slightly, placing additional outward pressure on the jaw. This will widen the gap in the center of the palate and new bone will grow to fill in the increased space. Over time this will cause the rear portion of maxilla to widen.
While effective, a palatal expander may not work in every case, and it must be done before the two bones fuse permanently. When it can be used, though, it’s a proven treatment that can restore proper bite function, as well as improve your child’s smile.

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.

If your smile is, to put it mildly, “unattractive,” you may think only extensive and expensive dental work can change it. But depending on your teeth’s actual condition, you might be able to obtain a new smile with a less-invasive option: porcelain veneers.
As their name implies, veneers are thin layers of dental porcelain bonded to the front of teeth to cover imperfections. They’re custom designed and manufactured by a dental technician to match the natural color, shape and size of the teeth they’re covering and to blend with neighboring teeth.
Veneers are quite effective for heavily stained, chipped or moderately misaligned teeth that are otherwise healthy. They can even be used to address slight gaps between teeth and restore worn teeth to make them appear larger and more youthful.
Overall, they’re less invasive than other dental restorations. That said, though, most veneers will still require some alteration of the affected teeth. This is because although quite thin they can still appear bulky after they’re bonded to the teeth. We can minimize this by removing a small amount of a tooth’s outer enamel. While this alteration is modest compared to other restorations, it’s nonetheless permanent– your teeth will require some form of restoration from then on.
Veneers also require special consideration while biting. You’ll need to exercise care and avoid biting hard items like candies (or using your teeth as tools) or the veneer could break. Similarly if you have a teeth grinding habit, you may want to consider having a custom guard created that you wear at night to prevent solid contact between your teeth. The excessive force generated while grinding or clenching teeth could also shatter veneers.
Veneers may not be the answer in all cosmetic dental situations, such as extensive disfigurements or bite problems. To know for sure if your particular dental condition could benefit, see your dentist for a complete dental examination and discuss whether obtaining veneers is a viable option for you. If so, you may be able to gain a much more attractive smile from this less invasive but no less effective option.

If you’re about to undergo orthodontic treatment, you’re going to face a challenge keeping your teeth and gums clean wearing braces. That in turn could increase your chances for tooth decay or periodontal (gum) disease, which could diminish your future dental health and disrupt your current orthodontic treatment.
The main hygiene tasks of brushing and flossing are more difficult with braces because of the fixed hardware on the teeth. Your toothbrush or floss can’t always easily maneuver around the wires and brackets, increasing the chances you’ll miss some areas. These neglected areas can then accumulate dental plaque, a thin film of bacteria and food particles that’s most responsible for disease.
But although difficult, effective oral hygiene isn’t impossible. First and foremost, you’ll need to take more time to be thorough with brushing and flossing than you might normally without braces.
Second, there are some specialized hygiene tools to make the job easier. Instead of a regular toothbrush try an interproximal brush. This special brush has a long and thin bristled head (resembling a pipe cleaner) that can maneuver in and around orthodontic hardware much easier than a regular brush.
For flossing, use a floss threader, a device through which you thread floss on one end and then pass the other sharper end between your teeth. Once through, you release the floss from it and floss as usual, repeating the process with the threader for each tooth. Another option is an oral irrigator, a device that emits a pressurized spray of water between teeth to loosen plaque and flush it away. Many orthodontic patients have found this latter option to be quite effective.
Finally, continue seeing your regular dentist for regular appointments in addition to your orthodontist. Besides cleaning those hard to reach areas, your dentist can also provide other preventive measures like topical fluoride for strengthening enamel and prescription mouth rinses that inhibit bacterial growth. You should also see your dentist immediately if you notice signs of disease like spots on the teeth or swollen or bleeding gums.
Keeping your teeth clean while wearing braces is a top priority. Doing so will help ensure your new smile after braces is both an attractive and healthy one.

Shingles is a painful viral infection that could potentially recur in sufferers for years. It causes painful skin rashes, general nerve pain, fever and fatigue. In extreme cases, it can cause blindness if the eyes become infected. And because it’s highly contagious, it could affect your dental treatment.
Formally known as herpes zoster, shingles is a recurrent form of chicken pox. If you contracted chicken pox in childhood, the shingles virus could lay dormant for several years. In fact, most people who contract shingles are over 50.
Because it acutely affects the nerves around the skin, the disease’s most common symptom is a belted or striped rash pattern that often appears on one side of the body and frequently on the head, neck or face. While the severity of symptoms may vary among patients, shingles can be a significant health threat to certain people, especially pregnant women, cancer patients or individuals with compromised immune systems.
In its early stages, the shingles virus can easily pass from person to person, either by direct contact with the rash or by airborne secretions that others can inhale. Because it’s highly contagious, even a routine teeth cleaning could potentially spread the virus to dental staff or other patients. Because of the significant health threat it potentially poses to some people, your dental provider may decline to treat you if you’re showing symptoms of the disease.
To stay ahead of this, let your dentist know you’re experiencing a shingles episode if you have an upcoming dental appointment, in which case you may need to reschedule. In the meantime, you should seek medical attention from your physician who may prescribe antiviral medication. Starting it within 3 days of a shingles outbreak can significantly reduce your pain and discomfort as well as its contagiousness.
And if you’re over sixty or at risk for shingles, consider getting the shingles vaccine. This readily available vaccine has proven effective in preventing the disease and could help you avoid the pain and disruption this viral infection can bring to your life.
