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.
If you would like more information on bonded retainers, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Bonded Retainers.”
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!
Your child could hit a speed bump on their road to dental maturity—tooth decay. In fact, children are susceptible to an aggressive form of decay known as Early Childhood Caries (ECC) that can lead to tooth loss and possible bite issues for other teeth.
But dentists have a few weapons in their arsenal for helping children avoid tooth decay. One of these used for many years now is the application of sealants to the biting surfaces of both primary and permanent teeth. Now, two major research studies have produced evidence that sealant applications help reduce children's tooth decay.
Applying sealant is a quick and painless procedure that doesn't require drilling or anesthesia. A dentist brushes the sealant in liquid form to the nooks and crannies of a tooth's biting surfaces, which tend to accumulate decay-causing bacterial plaque. They then use a curing light to harden the sealant.
The studies previously mentioned that involved thousands of patients over a number of years, found that pediatric patients without dental sealants were more than three times likely to get cavities compared to those who had sealants applied to their teeth. The studies also found the beneficial effect of a sealant could last four years or more after its application.
The American Dental Association and the American Academy of Pediatric Dentistry recommend sealants for children, especially those at high risk for decay. It's common practice now for children to first get sealants when their first permanent molars erupt (teeth that are highly susceptible to decay), usually between the ages of 5 and 7, and then later as additional molars come in.
There is a modest cost for sealant applications, but far less than the potential costs for decay treatment and later bite issues. Having your child undergo sealant treatment is a worthwhile investment: It could prevent decay and tooth loss in the near-term, and also help your child avoid more extensive dental problems in the future.
