KeepanEyeonTheseFourThingstoPreventAbnormalToothWear

Teeth are naturally strong and durable — if we can prevent or control dental disease like tooth decay or gum disease, they can last a lifetime. Still, teeth do wear gradually as we age, a fact we must factor into our dental care as we grow older.

Sometimes, though, the wear rate can accelerate and lead to problems much earlier — even tooth loss. There are generally four ways this abnormal wear can occur.

Tooth to tooth contact. Attrition usually results from habitual teeth grinding or clenching that are well beyond normal tooth contact. Also known as bruxism, these habits may occur unconsciously, often while you sleep. Treatments for bruxism include an occlusal guard worn to prevent tooth to tooth contact, orthodontic treatment, medication, biofeedback or psychological counseling to improve stress coping skills.

Teeth and hard material contact. Bruxism causes abrasion when our teeth regularly bite on hard materials such as pencils, nails, or bobby pins. The constant contact with these and other abrasive surfaces will cause the enamel to erode. Again, learning to cope with stress and breaking the bruxism habit will help preserve the remaining enamel.

Chronic acid. A high level of acid from foods we eat or drink can erode tooth enamel. Saliva naturally neutralizes this acid and restores the mouth to a neutral pH, usually within thirty minutes to an hour after eating. But if you’re constantly snacking on acidic foods and beverages, saliva’s buffering ability can’t keep up. To avoid this situation, refrain from constant snacking and limit acidic beverages like sodas or sports drinks to mealtimes. Extreme cases of gastric reflux disease may also disrupt your mouth’s pH — seek treatment from your medical doctor if you’re having related symptoms.

Enamel loss at the gumline. Also known as abfraction, this enamel loss is often caused by receding gums that expose more of the tooth below the enamel, which can lead to its erosion. Preventing and treating gum disease (the leading cause of receding gums) and proper oral hygiene will lower your risks of receding gums and protect tooth enamel.

Implant-SupportedDenturesCouldContributetoBetterBoneHealth

For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.

Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.

Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.

Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.

In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.

Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.

Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.

There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.

BaseballFanCatchesHerOwnKnocked-OutTooth

When your favorite baseball team wins, it's hard not to get excited — especially if you're right there in the stadium. It's even better when a player tosses the ball to fans. But sometimes, in the heat of the moment, things can go awry.

That's what happened during a recent game at New York's Yankee Stadium. After catching the ball that ended the game in an 8-2 Dodgers win, Los Angeles outfielder Yasiel Puig tossed it into a cheering crowd of supporters. “I saw it coming at me and I remember thinking, 'I don't have a glove to catch this ball,'” Dodgers fan Alyssa Gerharter told the New York Daily News. “I felt it hit me and I could feel immediately with my tongue there's a hole. And I looked down at my hand and saw there's a tooth in my hand.”

Ouch. Just like that, one fan's dream became… a not-so-good dream. But fortunately for the 25-year-old software engineer, things went uphill from there. Ushers quickly escorted her into a first-aid room at the stadium. She was then rushed to a nearby hospital, where the upper front tooth was re-inserted into her jaw. After a follow-up appointment at her dentist's office the next day, Gerharter said she remains hopeful the re-inserted tooth will fuse with the bone, and won't require replacement.

We hope so too. And in fact, she has as good a chance of a successful outcome as anyone, because she did everything right. If you're not sure what to do about a knocked-out tooth, here are the basics:

  • locate the tooth, handle it carefully (don't touch the root surface), and if possible gently clean it with water
  • try to open the person's mouth and find the place where the tooth came from
  • carefully re-insert the tooth in its socket if possible, making sure it is facing the right way
  • hold the tooth in place with a soft cloth as you rush to the dental office or the nearest urgent care facility
  • if it can't be replaced in its socket, place the tooth in a special preservative solution or milk, or have the person hold it between the cheek and gum (making sure they won't swallow it) — and then seek immediate care at the dental office
  • follow up at the dental office as recommended

In general, the quicker you perform these steps, the more likely it is that the tooth can be preserved. How quick is quick? The best outcomes are expected when re-implantation occurs in no more than five minutes. So if you're in this situation, don't wait: get (or give) appropriate first aid right away — it just might save a tooth!

GameSetMatchMilosRaonicSaysAMouthguardHelpsHimWin

When you’re among the top players in your field, you need every advantage to help you stay competitive: Not just the best equipment, but anything else that relieves pain and stress, and allows you to play better. For top-seeded Canadian tennis player Milos Raonic, that extra help came in a somewhat unexpected form: a custom made mouthguard that he wears on the court and off. “[It helps] to not grind my teeth while I play,” said the 25-year-old up-and-coming ace. “It just causes stress and headaches sometimes.”

Mouthguards are often worn by athletes engaged in sports that carry the risk of dental injury — such as basketball, football, hockey, and some two dozen others; wearing one is a great way to keep your teeth from being seriously injured. But Raonic’s mouthguard isn’t primarily for safety; it’s actually designed to help him solve the problem of teeth grinding, or bruxism. This habitual behavior causes him to unconsciously tense up his jaw, potentially leading to problems with muscles and teeth.

Bruxism is a common issue that’s often caused or aggravated by stress. You don’t have to be a world-class athlete to suffer from this condition: Everyday anxieties can have the same effect. The behavior is often worsened when you consume stimulating substances, such as alcohol, tobacco, caffeine, and other drugs.

While bruxism affects thousands of people, some don’t even suspect they have it. That’s because it may occur at any time — even while you’re asleep! The powerful jaw muscles that clench and grind teeth together can wear down tooth enamel, and damage both natural teeth and dental work. They can even cause loose teeth! What’s more, a clenching and grinding habit can result in pain, headaches and muscle soreness… which can really put you off your game.

There are several ways to relieve the problem of bruxism. Stress reduction is one approach that works in some cases. When it’s not enough, a custom made occlusal guard (also called a night guard or mouthguard) provided by our office can make a big difference. “When I don’t sleep with it for a night,” Raonic said “I can feel my jaw muscles just tense up the next day. I don’t sense myself grinding but I can sort of feel that difference the next day.”

 An occlusal guard is made from an exact model of your own mouth. It helps to keep your teeth in better alignment and prevent them from coming into contact, so they can’t damage each other. It also protects your jaw joints from being stressed by excessive force. Plus, it’s secure and comfortable to wear. “I wear it all the time other than when I’m eating, so I got used to it pretty quickly,” said Raonic.

Teeth grinding can be a big problem — whether you put on your game face on the court… or at home. If you would like more information about bruxism, contact us or schedule an appointment for a consultation.

KeepaCloseEyeonYourDentalHealthWhileUndergoingCancerTreatment

As a cancer patient, you know how important radiation and chemotherapy are to overcoming the disease. But these treatments often come at a price to other aspects of your health, including your teeth and gums if the treatment target includes the head or neck regions.

Radiation and chemotherapy are effective because they target and destroy cancer cells. Unfortunately, they may also kill non-cancerous, healthy cells; in the mouth, for example, they can damage the cells in the salivary glands and disrupt their ability to produce adequate saliva flow, leading to xerostomia (dry mouth).

This could seriously affect your teeth’s protective enamel shell. As we eat or drink, our mouth’s pH level can become too acidic. Acid is your enamel’s primary enemy because it causes the minerals in the enamel to soften and dissolve (de-mineralization). Saliva neutralizes acid and replaces much of the enamel’s minerals.

Without adequate saliva flow, the enamel will tend to erode over time. You can further aggravate the situation if you routinely consume acidic foods and drinks, like sipping energy drinks or soda during the day. Once the enamel is gone it can’t be replaced naturally, and the teeth will be in serious danger of tooth decay and eventual loss of function and appearance.

To avoid these consequences you should take steps during cancer treatment to reduce your risk for xerostomia or other unhealthy mouth conditions: limit your consumption of acidic foods and beverages; use mouth rinses to counteract acidity and inhibit bacterial growth; and promote saliva flow through medication.

It may be, though, that enamel erosion and subsequent tooth damage is unavoidable. In this case, you may need to consider restorative options with artificial crowns or other cosmetic enhancements — not only to improve your appearance but also to protect your natural teeth from further damage.

Before considering the latter, you should undergo a complete dental examination to assess your condition and make sure you have adequate bone and gum support, and any dental disease under control. From here, we can go about restoring the attractive smile that may have faded during your battle with cancer.
