ErosionandOtherProblemsmaybeSignsofBulimia

The mouth isn’t an island unto itself — problems there may be indicative of deeper physical or emotional issues.  The condition of a family member’s teeth and gums, for example, could be signs of bulimia, an eating disorder.

Characterized by food binging and purging through self-induced vomiting, bulimia can also have a severe effect on the teeth. Regular inducement of vomiting introduces stomach acid into the mouth that can attack and soften the mineral content of tooth enamel. As a result, 90% of bulimics develop enamel erosion.

The erosion pattern often differs from that produced by other high acid causes like the over-consumption of sodas. Because the tongue instinctively covers the back of the bottom teeth during vomiting, they’re often shielded from much of the acid wash. Bulimics are much more apt to exhibit heavier erosion on the upper front teeth, particularly on the tongue side and biting edges.

Bulimia and similar disorders produce other signs as well, like soft tissue ulceration or swollen salivary glands that exhibit puffiness of the face. The roof of the mouth, throat and back of the tongue may appear roughened from the use of fingers or objects to induce gagging.

Unlike sufferers of anorexia nervosa who tend to be negligent about their hygiene (which itself increases their risk of dental disease), bulimics have a heightened sensitivity to their appearance. This concern may prompt them to aggressively brush right after purging, which can cause more of the softened enamel to be removed.

Treating the dental consequences of bulimia requires a two-pronged approach. In the short term, we want to lessen the impact of stomach acid by discouraging the person from brushing immediately after purging — better to rinse with water and a little baking soda to buffer the acid and wait about an hour before brushing. We may also suggest a sodium fluoride mouth rinse to help strengthen and re-mineralize the enamel.

In the long-term, though, the disorder itself must be addressed through professional help. One good source is the National Eating Disorders website (nationaleatingdisorders.org). Besides information, the association also provides a toll-free helpline for referrals to professionals.

As with any eating disorder, bulimia can be trying for patients and their families. Addressing the issue gently but forthrightly will begin their journey toward the renewal of health, including their teeth and gums.

DontBreakItLikeBeckham

During his former career as a professional footballer (that's a soccer star to U.S. sports fans) David Beckham was known for his skill at “bending” a soccer ball. His ability to make the ball curve in mid-flight — to avoid a defender or score a goal — led scores of kids to try to “bend it like Beckham.” But just recently, while enjoying a vacation in Canada with his family, “Becks” tried snowboarding for the first time — and in the process, broke one of his front teeth.

Some fans worried that the missing tooth could be a “red card” for Beckham's current modeling career… but fortunately, he headed straight to the dental office as soon as he arrived back in England. Exactly what kind of treatment is needed for a broken tooth? It all depends where the break is and how badly the tooth is damaged.

For a minor crack or chip, cosmetic bonding may offer a quick and effective solution. In this procedure, a composite resin, in a color custom-made to match the tooth, is applied in liquid form and cured (hardened) with a special light. Several layers of bonding material can be applied to re-construct a larger area of missing tooth, and chips that have been saved can sometimes be reattached as well.

When more tooth structure is missing, dental veneers may be the preferred restorative option. Veneers are wafer-thin shells that are bonded to the front surface of the teeth. They can not only correct small chips or cracks, but can also improve the color, spacing, and shape of your teeth.

But if the damage exposes the soft inner pulp of the tooth, root canal treatment will be needed to save the tooth. In this procedure, the inflamed or infected pulp tissue is removed and the tooth sealed against re-infection; if a root canal is not done when needed, the tooth will have an increased risk for extraction in the future. Following a root canal, a tooth is often restored with a crown (cap), which can look good and function well for many years.

Sometimes, a tooth may be knocked completely out of its socket; or, a severely damaged tooth may need to be extracted (removed). In either situation, the best option for restoration is a dental implant. Here, a tiny screw-like device made of titanium metal is inserted into the jaw bone in a minor surgical procedure. Over time, it fuses with the living bone to form a solid anchorage. A lifelike crown is attached, which provides aesthetic appeal and full function for the replacement tooth.

So how's Beckham holding up? According to sources, “David is a trooper and didn't make a fuss. He took it all in his stride." Maybe next time he hits the slopes, he'll heed the advice of dental experts and wear a custom-made mouthguard…

If you have questions about restoring damaged teeth, please contact our office to schedule a consultation. You can read more in the Dear Doctor magazine articles “Trauma and Nerve Damage to Teeth” and “Children's Dental Concerns and Injuries.”

SleepApneaMightbeRobbingyouofMorethanaGoodNightsSleep

Fatigue, a “foggy” mind, and irritability are all signs you’re not getting enough sleep—and neither might your sleeping partner from your continuous snoring. You might have a common form of sleep-related breathing disorder (SRBD) known as obstructive sleep apnea.

Sleep apnea occurs when the airway becomes obstructed (usually by the tongue), resulting in a lack of oxygen. The body rouses from sleep just enough to correct the obstruction. This can occur and interrupt deep sleep several times a night, causing the aforementioned problems as well as personality changes, high blood pressure or increased stomach acid reflux. If the problem persists, sleep apnea could also become a long-term factor in the development of heart disease, diabetes or other serious conditions.

Fortunately, we can do something about it. While some may require more invasive intervention, most cases of sleep apnea can be alleviated through continuous positive airway pressure (CPAP) therapy. In this therapy, an electrical pump supplies pressurized air into a face mask worn while sleeping. The increased air pressure helps to keep the airway open.

For some patients, however, CPAP can cause discomfort like claustrophobia, nasal congestion and dryness. If that’s a concern for you, you might want to consider an oral appliance provided by your dentist.

Customized to your own individual mouth contours, this appliance is usually a two-part hinged device that draws the lower jaw and the tongue forward to open the airway. Easily adjustable, these appliances are usually more comfortable to wear than a CPAP and don’t require electricity or have the attendant noise of a CPAP pump.

They do, however, have a few drawbacks: they can disrupt saliva flow, causing either too much or too little; they may result in some morning soreness; and they can stimulate unnecessary tooth or jaw movements. For most, though, these side effects are minor compared to a better night’s sleep.

If you suspect you may have some form of SRBD, you’ll need to have it confirmed through a physical examination and possibly sleep lab testing. If it is sleep apnea, your physician and dentist can work together to help you find the right therapy to regain the benefits of a good night’s sleep.

If you would like more information on sleep apnea, 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 “Sleep Disorders & Dentistry.”

Root CanalSevere toothaches and constant mouth pain or pressure can be signs you need a root canal. Root canals can save severely damaged or infected teeth from extraction. The root canal procedure strengthens and restores problem teeth so they can resume normal biting and chewing functions without pain or sensitivity. At Newmarket Dentistry, your family dentistry practice in Newmarket, ON, Dr. Richard Lee-Shanok restores damaged and infected teeth with root canal therapy.

What is Root Canal Therapy?

Root canal therapy is a restorative dental treatment for repairing teeth that have been severely damaged by infection or injury. In some cases, teeth with severe damage must be extracted. In many cases, though, root canal therapy can be used to strengthen and restore teeth so extraction is not necessary. Root canal therapy is needed when the soft pulp material in the center of a tooth and root is infected. The infection can even lead to the formation of an abscess below the tooth root. A root canal might be needed if you have any of the following symptoms:

  • A severe or persistent toothache
  • Constant mouth pain or pressure
  • Sharp pain when chewing or biting food
  • Sensitivity to hot or cold foods and beverages

During a root canal procedure, the infected pulp in the center of the tooth and root is completely removed. Then, the tooth and root are thoroughly cleaned inside to ensure all signs of infection and debris have been cleared away. Finally, dental filling is added to the interior of the tooth and root. The dental filling strengthens and restores the tooth, while also preventing additional infection from developing in the area again. A dental crown may also be needed to protect the tooth. Your Newmarket dentist for family dentistry can determine if your tooth needs root canal therapy.

Benefits of Root Canal Therapy

There are multiple benefits to undergoing root canal therapy for teeth on the verge of extraction. Some of the many benefits of root canal therapy include:

  • Preventing extraction
  • Removing infected pulp
  • Preventing the spread of infection
  • Strengthening and restoring damaged or infected teeth
  • Alleviating tooth pain and sensitivity

Root canal therapy offers several benefits, from preventing extraction to restoring damaged teeth. If you have developed any of the symptoms associated with needing a root canal, schedule an appointment with Dr. Lee-Shanok by calling Newmarket Dentistry at (905) 830-1010.

IfYouvehadJointReplacementyoumayNeedAntibioticsBeforeDentalWork

If you’ve had a total joint replacement or similar procedure, you will want your surgeon to decide if you need to take an antibiotic before you undergo dental work. This is a precaution to prevent a serious infection known as bacteremia.

Bacteremia occurs when bacteria become too prevalent in the bloodstream and cause infection in other parts of the body, especially in joints and bone with prosthetic (replacement) substances. It’s believed that during invasive dental procedures bacteria in the mouth can enter the bloodstream through incisions and other soft tissue disruptions.

Joint infections are a serious matter and can require extensive therapy to bring it under control. Out of this concern, the use of antibiotics as a prophylactic (preventive measure) against bacteremia once included a wide range of patients for a variety of conditions and procedures. But after an in-depth study in 2007, the American Dental Association concluded that the risks for many of these patient groups for infection triggered by a dental procedure was extremely low and didn’t warrant the use of antibiotic premedication therapy.

As a result, recommendations for antibiotic therapy changed in 2009, eliminating many groups previously recommended for premedication. But because of the seriousness of joint infection, The American Academy of Orthopedic Surgeons still recommends the therapy for joint replacement patients about to undergo any invasive procedure, including dental work. It’s especially needed for patients who also have some form of inflammatory arthritis, a weakened immune system, insulin-dependent diabetes, hemophilia, malnourishment or a previous infection in an artificial joint.

The guidelines for antibiotic premedication can be complex. It’s best, then, to speak with both your orthopedic surgeon and us about whether you should undergo antibiotic therapy before you undergo a dental procedure. The ultimate goal is to reduce the risks of any disease and to keep both your mouth and your body safe from infection.

If you would like more information on the use of antibiotics in dental care, 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 “Premedication for Dental Treatment.”
