While retainers are often viewed as a nuisance, they’re crucial to protect the gains made with bite correction. Without them, all of the progress achieved through braces or clear aligners could be lost.
Here’s why: The same elastic gum tissue called the periodontal ligament that holds teeth in place also allows them to move incrementally in response to changes in the mouth. That’s why we can move teeth with braces or aligners, which put pressure on the teeth toward a desired direction of movement while the periodontal ligament does the rest.
But the mechanics can also work in reverse: With pressure relieved when the braces are removed, the teeth could revert to their original positions through a kind of “muscle memory.” The light pressure provided by a retainer is enough to keep or “retain” teeth in their new positions.
The best known retainer is a removable appliance. Initially, a patient wears it continuously and only takes it out during oral hygiene. Wear duration may later be reduced to night time only and eventually not at all, depending on a patient’s individual needs.
While effective, removable retainers do have some downsides. Like braces, they’re visible to others. And because they’re removable, they’re frequently misplaced or lost, leading to the added expense of a new one.
An alternative is a bonded retainer, a thin piece of wire attached to the back of the newly moved teeth to keep them in place. Because it’s behind the teeth it’s not visible—and there’s no misplacing it because only a dentist can take it out.
A bonded retainer is a good option, especially if a patient is immature and not as diligent about wearing or keeping up with their appliance. But it can make flossing difficult to perform, and if they’re removed or broken prematurely, the teeth could revert to their former positions.
If you decide to go with a bonded retainer, be sure you get some tips from your dental hygienist on how to floss with it. And if you decide later to have it removed early, be sure to replace it with a removable retainer. Either of these two options can help you keep your new and improved smile.

Daily oral hygiene and regular dental cleanings help keep your natural teeth and gums healthy and disease-free. But they're also a priority with dental implants. Here's why.
Unlike other restorations, an implant replaces both a tooth's crown and root, the latter by way of a titanium metal post imbedded into the jawbone. Bone cells grow and adhere to the metal surface, forming a secure and lasting hold.
But although quite durable, this hold differs significantly from natural teeth, which are actually held in place by a tough, elastic tissue called the periodontal ligament. The attachment of the ligament's tiny fibers to both tooth and bone secure the tooth in place, as well as supply it and the surrounding gums with nutrients and defensive antibodies to fight infection.
Implants don't have this relationship with the periodontal ligament. The tissues around an implant are thus susceptible to an aggressive form of periodontal (gum) disease called peri-implantitis. This kind of gum infection can progress rapidly, leading eventually to bone loss and possible failure of the implant.
Daily brushing and flossing of both natural and implant-supported teeth lowers the risk of gum disease, particularly peri-implantitis. It's also imperative that you undergo regular cleanings, at least every six months, with your dentist or dental hygienist.
These, however, won't be the typical cleanings performed on natural teeth. Hygienists don't use metal cleaning implements to remove plaque and tartar deposits because they can scratch the metal materials of the implant and crown. These microscopic scratches can then attract bacteria that trigger gum infections. Instead, they'll use instruments made of plastics or resins.
Hygienists also rely heavily on ultrasonic equipment that vibrates plaque loose on or around implants, which are then flushed away with water. The tips used with these instruments are also typically made of nylon or plastic sheathing.
Even with the extra hygiene care needed, implants still enjoy a 95% or higher survival rate after ten years. You can ensure your implants achieve that level of durability by keeping them clean and seeing your dentist at the first sign of a gum infection.

Before implants, people often turned to a removable appliance to replace multiple missing teeth. Known as a removable partial denture (RPD), this appliance could restore both appearance and function at an affordable price.
But although implants may have diminished their use, RPDs haven't gone extinct. They're still a viable option for patients who can't afford implants or fixed bridgework, or who can't obtain implants due to the state of their dental health.
Although replacing only a few teeth rather than an entire arch, RPDs are similar in basic concept to full dentures. The prosthetic (artificial) teeth are anchored in a resin or plastic that's colored to resemble the gums, precisely placed to fit into the missing gaps. This assembly is further supported by a frame made of vitallium, a lightweight but strong metal alloy. The appliance fits upon the arch with the missing teeth, supported by vitallium clasps that grip adjacent natural teeth.
Each RPD must be custom designed for each patient to fit perfectly without excessive movement during chewing. Too much movement could warp the fit, reduce the RPD's durability or damage other teeth. To achieve this secure fit, dentists must take into account the number and location of missing teeth to be replaced, and then apply a specific construction pattern to balance the appliance.
There are RPDs that are meant to be used short-term, as with a teenager whose jaw isn't yet mature for dental implants. But the metal-framed RPDs we've described are designed for long-term use. There is, however, one primary downside: RPDs have a propensity to collect dental plaque, a thin biofilm most responsible for dental disease that could further deteriorate your dental health.
To avoid this, you'll need to keep both the RPD and the rest of your teeth and gums as clean as possible with daily brushing and flossing, and appliance care. And like dentures, it's best to remove the RPD when you go to bed at night to discourage the growth of harmful bacteria.
To see if an RPD to replace your missing teeth is an option for you, visit us for a complete dental exam. From there, we can advise you further as to whether an RPD could affordably restore your missing teeth and your smile.

You probably wouldn't be surprised to hear that someone playing hockey, racing motocross or duking it out in an ultimate fighter match had a tooth knocked out. But acting in a movie? That's exactly what happened to Howie Mandel, well-known comedian and host of TV's America's Got Talent and Deal or No Deal. And not just any tooth, but one of his upper front teeth—with the other one heavily damaged in the process.
The accident occurred during the 1987 filming of Walk Like a Man in which Mandel played a young man raised by wolves. In one scene, a co-star was supposed to yank a bone from Howie's mouth. The actor, however, pulled the bone a second too early while Howie still had it clamped between his teeth. Mandel says you can see the tooth fly out of his mouth in the movie.
But trooper that he is, Mandel immediately had two crowns placed to restore the damaged teeth and went back to filming. The restoration was a good one, and all was well with his smile for the next few decades.
Until, that is, he began to notice a peculiar discoloration pattern. Years of coffee drinking had stained his other natural teeth, but not the two prosthetic (“false”) crowns in the middle of his smile. The two crowns, bright as ever, stuck out prominently from the rest of his teeth, giving him a distinctive look: “I looked like Bugs Bunny,” Mandel told Dear Doctor—Dentistry & Oral Health magazine.
His dentist, though, had a solution: dental veneers. These thin wafers of porcelain are bonded to the front of teeth to mask slight imperfections like chipping, gaps or discoloration. Veneers are popular way to get an updated and more attractive smile. Each veneer is custom-shaped and color-matched to the individual tooth so that it blends seamlessly with the rest of the teeth.
One caveat, though: most veneers can look bulky if placed directly on the teeth. To accommodate this, traditional veneers require that some of the enamel be removed from your tooth so that the veneer does not add bulk when it is placed over the front-facing side of your tooth. This permanently alters the tooth and requires it have a restoration from then on.
In many instances, however, a “minimal prep” or “no-prep” veneer may be possible, where, as the names suggest, very little or even none of the tooth's surface needs to be reduced before the veneer is placed. The type of veneer that is recommended for you will depend on the condition of your enamel and the particular flaw you wish to correct.
Many dental patients opt for veneers because they can be used in a variety of cosmetic situations, including upgrades to previous dental work as Howie Mandel experienced. So if slight imperfections are putting a damper on your smile, veneers could be the answer.

Even the simplest, everyday things can be challenging for a child with special needs. Dental care is no exception.
If you have a child with a chronic condition that affects their physical, intellectual or behavioral abilities, you know how difficult keeping up with dental care practices can be. Here are 4 tips to help make dental care easier and ensure your child has healthy teeth and gums.
Take an active role in hygiene. Depending on their abilities, you may need to take a more active role in daily teeth cleaning. If you have to brush their teeth for them, it's usually easier to have them face you “knee-to-knee.” You can also use a second brush to keep their mouth propped open if they tend to bite or clench down while brushing.
Model behavior. If your child could eventually brush for themselves, it may still be a long training road. It can be an easier task if you make a habit of brushing your teeth together, or have them brush with a sibling. Not only does this allow you to monitor their progress, their learning process may be easier watching another person brush and then mimicking their actions.
Find the right dentist. Many children with special needs are subject to anxiety surrounding healthcare visits, including going to the dentist. Choosing the right dentist, skilled in the technical aspects of treatment for a special needs child and providing a “kid-friendly” environment, can make all the difference in the world. A pediatric dentist is often a good fit for children with chronic conditions.
Coordinate medical and dental care. A special needs child could have underlying health problems that complicate dental care, so keep your dentist well-informed about their overall health. Do likewise with their medical providers, particularly if their condition or treatments impact dental health, as in the case of medications they're taking that could inhibit saliva flow.
Ongoing dental care for a child with a chronic health condition can be difficult. But keeping their teeth and gums healthy is an important part of fostering greater overall health.
