ABondedRetainerMightbeaBetterChoiceAfterBraces

The braces are finally off! But to keep your new, straighter smile you'll need to wear a retainer for some time. That's because the same structural mechanism used to move your teeth could undo what we've just accomplished.

That mechanism resides in an elastic tissue called the periodontal ligament that lies between the teeth and the bone and attaches to both with tiny fibers. While the ligament holds the teeth securely in place, it also allows for slight movement in response to bite changes. Braces "pull" the teeth in the desired new direction, and the ligament responds.

But with that pressure gone after the braces' removal, a kind of "muscle memory" can set in that moves the teeth back towards their original positions. A retainer, a dental appliance worn on the teeth, exerts just enough pressure to "retain" or keep the teeth from regressing.

Retainers are effective, but the most common type has a feature that poses potential problems: it can be removed by the wearer. Because of this, less disciplined patients might be tempted not to wear their retainer as directed. There's also a higher risk of losing one and incurring additional cost to replace it.

But there is another type, the bonded retainer, which stays permanently in the mouth until removed by an orthodontist. It's composed of a thin piece of metal that's firmly attached to the back of the teeth with dental composite material. Not only does a bonded retainer solve the problems mentioned before, it also can't be seen from the outside like a removable retainer.

A bonded retainer does have one disadvantage: because it can't be removed, it can obstruct the teeth during brushing and flossing and require more effort. You won't have as much difficulty with a removable retainer keeping teeth and gums clean. You can overcome this disadvantage, though, with specialized tools like a water flosser or a floss threader to make hygiene easier.

To choose which type of retainer is best for you or your family member, have a talk with your orthodontist. And if you choose a bonded retainer and later have it removed, be sure to switch immediately to a removable one if your orthodontist advises. With either retainer, you'll be able to preserve that hard-earned smile for years to come.

ToDetectOralCancerEarlySeeYourDentist

This month marks the 20th annual observance of Oral Cancer Awareness Month. Last year, over 50,000 people in the US were diagnosed with oral cancer, and over 10,000 people died from the disease. The 5-year survival rate for oral cancer is only around 57%, making it more deadly than many other types of cancer. But if oral cancer is caught and treated early, the 5-year survival rate jumps to over 80%. This is one reason why regular dental checkups are so important—we can be your best ally in detecting oral cancer in its early stages.

Oral cancer is particularly dangerous because it often develops without pain or obvious symptoms. Early detection greatly improves the chances of successful treatment, but signs of the disease frequently go unnoticed until the cancer is advanced. Fortunately, dentists and dental hygienists are trained to recognize signs of oral cancer in the early stages, when it is most treatable. Oral cancer can appear on any surface of the mouth and throat, with the tongue being the most common site, particularly along the sides, followed by the floor of the mouth. As part of a regular dental exam, we examine these surfaces for even subtle signs of the disease.

Screenings performed at the dental office are the best way to detect oral cancer, but between dental visits it's a good idea to check your own mouth for any of the following: white or red patches, lumps, hard spots, spots that bleed easily or sores that don't heal. Let us know if any of these symptoms don't go away on their own within two or three weeks.

Using tobacco in any form is a major risk factor for oral cancer, especially in combination with alcohol consumption. Although the majority of people diagnosed with oral cancer are over age 55, the fastest growing segment of new diagnoses are among young people due to the rise in cases of sexually transmitted human papillomavirus (HPV) in young adults.

A routine dental visit can do much more than preventing and treating tooth decay and gum disease—it might even save your life! If you have questions about oral cancer or are concerned about possible symptoms, call us as soon as possible to schedule an appointment for a consultation.

WhatYouShouldDotoProtectanOlderLovedOnesDentalHealth

If you're the principal caregiver for an older person, you may have already faced age-related health challenges with them. Good preventive care, however, can ease the impact of health problems. This is especially true for their teeth and gums: with your support you're loved one can have fewer dental problems and enjoy better health overall.

Here are a number of things you should focus on to protect an older person's dental health.

Hygiene difficulties. With increased risk of arthritis and similar joint problems, older people may find brushing and flossing more difficult. You can help by modifying their toothbrush handles with a tennis ball or bicycle grip for an easier hold, or switch them to an electric toothbrush. A water flosser, a device that uses a pressurized water spray to remove plaque, may also be easier for them to use than thread flossing.

Dry mouth. Xerostomia, chronic dry mouth, is more prevalent among older populations. Dry mouth can cause more than discomfort—with less acid-neutralizing saliva available in the mouth, the risk for dental diseases like tooth decay or periodontal (gum) disease can soar. To improve their saliva flow, talk with their doctors about alternative medications that cause less dry mouth; and encourage your loved one to drink more water and use products that help boost saliva flow.

Dentures. If your older person wears dentures, be sure these appliances are being cleaned and maintained daily to maximize their function and reduce disease-causing bacteria. You should also have their dentures fit-tested regularly—chronic jawbone loss, something dentures can't prevent, can loosen denture fit over time. Their dentures may need to be relined or eventually replaced to ensure continuing proper fit and function.

Osteoporosis. This common disease in older people weakens bone structure. It's often treated with bisphosphonates, a class of drugs that while slowing the effects of osteoporosis can cause complications after certain dental procedures. It's a good idea, then, for an older person to undergo any needed dental work before they go on osteoporosis medication.

Keep alert also for any signs of dental disease like unusual spots on the teeth or swollen or bleeding gums. Visiting the dentist for these and regular dental cleanings, checkups and oral cancer screenings could prevent many teeth and gum problems.

DentalInjuryIsJustaTemporarySetbackforBasketballStarKevinLove

The March 27th game started off pretty well for NBA star Kevin Love. His team, the Cleveland Cavaliers, were coming off a 5-game winning streak as they faced the Miami Heat that night. Less than two minutes into the contest, Love charged in for a shot on Heat center Jordan Mickey—but instead of a basket, he got an elbow in the face that sent him to the floor (and out of the game) with an injury to his mouth.

In pictures from the aftermath, Love’s front tooth seemed clearly out of position. According to the Cavs’ official statement, “Love suffered a front tooth subluxation.” But what exactly does that mean, and how serious is his injury?

The dental term “subluxation” refers to one specific type of luxation injury—a situation where a tooth has become loosened or displaced from its proper location. A subluxation is an injury to tooth-supporting structures such as the periodontal ligament: a stretchy network of fibrous tissue that keeps the tooth in its socket. The affected tooth becomes abnormally loose, but as long as the nerves inside the tooth and the underlying bone have not been damaged, it generally has a favorable prognosis.

Treatment of a subluxation injury may involve correcting the tooth’s position immediately and/or stabilizing the tooth—often by temporarily splinting (joining) it to adjacent teeth—and maintaining a soft diet for a few weeks. This gives the injured tissues a chance to heal and helps the ligament regain proper attachment to the tooth. The condition of tooth’s pulp (soft inner tissue) must also be closely monitored; if it becomes infected, root canal treatment may be needed to preserve the tooth.

So while Kevin Love’s dental dilemma might have looked scary in the pictures, with proper care he has a good chance of keeping the tooth. Significantly, Love acknowledged on Twitter that the damage “…could have been so much worse if I wasn’t protected with [a] mouthguard.”

Love’s injury reminds us that whether they’re played at a big arena, a high school gym or an outdoor court, sports like basketball (as well as baseball, football and many others) have a high potential for facial injuries. That’s why all players should wear a mouthguard whenever they’re in the game. Custom-made mouthguards, available for a reasonable cost at the dental office, are the most comfortable to wear, and offer protection that’s superior to the kind available at big-box retailers.

If you have questions about dental injuries or custom-made mouthguards, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “The Field-Side Guide to Dental Injuries” and “Athletic Mouthguards.”

3ThingsYouShouldKnowAboutTeethGrinding

Do you grind your teeth? If you're not sure, ask your family—sometimes the sound of teeth grinding against teeth might make enough noise to be keeping them up at night. You might also be waking with sore jaw muscles and joints.

If you suspect you have this habit of involuntarily grinding, gnashing or clenching your teeth, it's a good idea to get it checked. Here are 3 things you should know about this odd habit.

Teeth-grinding more prevalent among children. Children are more likely than adults to grind their teeth in their sleep, thought to be a consequence of their developing swallowing mechanism, but usually grow out of it without any long-term effects. Adults with the habit seem to grind their teeth for different reasons, one of the most significant being a response to high stress. Tobacco could be another factor: users are twice as likely as non-users to grind their teeth. Adult teeth-grinding may also be associated with high caffeine consumption, illicit drug use or Parkinson's Disease, which impairs brain nerve function.

Sleep apnea can be an underlying cause. There's one other major underlying cause to add to that list: obstructive sleep apnea. One international study of thousands of patients from different countries found both high anxiety or stress and sleep-related breathing disorders were two of the most significant risk factors for adult teeth-grinding. It's believed the physical stress generated by these temporary episodes of breathing obstruction occurring several times a night could trigger teeth-grinding.

Teeth-grinding can cause dental problems. While having a teeth-grinding habit doesn't automatically mean you'll have dental issues, your risk can increase dramatically. Due to its chronic nature, teeth-grinding can lead to excessive tooth wear, dental work damage or jaw joint dysfunction. In some extreme cases, it could cause tooth fracture.

If you grind your teeth, your dentist may be able to help by creating a custom-made occlusal guard that can reduce biting forces while you're wearing it. You might also minimize teeth-grinding by quitting tobacco and other lifestyle changes, or getting a better handle on stress management. And if you're also diagnosed with obstructive sleep apnea, getting treatment for that condition will not only improve your overall health, it could help put an end to your teeth-grinding habit.
