FluoridatedDrinkingWaterHelpsCurbToothDecaySafely

The U.S. Centers for Disease Control and Prevention calls it “one of the ten most important public health measures of the 20th Century.” A new vaccine? A cure for a major disease? No—the CDC is referring to the addition of fluoride to drinking water to prevent tooth decay.

Fluoride is a chemical compound found in foods, soil and water. Its presence in the latter, in fact, was key to the discovery of its dental benefits in the early 20th Century. A dentist in Colorado Springs, Colorado, whose natural water sources were abundant with fluoride, noticed his patients' teeth had unusual staining but no tooth decay. Curious, he did some detective work and found fluoride in drinking water to be the common denominator.

By mid-century, fluoride was generally recognized as a cavity fighter. But it also had its critics (still lively today) that believed it might also cause serious health problems. Ongoing studies, however, found that fluoride in tiny amounts—as small as a grain of sand in a gallon of water—had an immense effect strengthening enamel with scant risk to health.

The only condition found caused by excess fluoride is a form of tooth staining called fluorosis (like those in Colorado Springs). Fluorosis doesn't harm the teeth and is at worst a cosmetic problem. And it can be avoided by regulating the amount of ingested fluoride to just enough for effectively preventing tooth decay.

As researchers have continued to learn more about fluoride, we've fine-tuned what that amount should be. The U.S. Public Health Service (PHS), which sets standards for fluoride in drinking water, now recommends to utilities that fluoridate water to do so at a ratio of 0.7 mg of fluoride to 1 liter of water. This miniscule amount is even lower than previous recommendations.

The bottom line: Fluoride can have an immense impact on your family's dental health—and it doesn't take much. Excessive amounts, though, can lead to dental staining, so it's prudent to monitor your intake. That means speaking with your dentist about the prevalence of fluoride in your area (including your drinking water) and whether you need to take measures to reduce (or expand) your use of it.

3ThingsYouNeedtoKnowBeforeGettingaCrownRestoration

You may think all crowns are alike—but there can be a world of difference between one crown and another. Getting the crown your dentist recommends and one that's satisfactory to you will depend on a number of factors, including what you'll ultimately have to pay.

Here are 3 things you need to know about crowns before undergoing a crown restoration.

Different materials. Although porcelain is the most life-like material used, earlier types of this glass-based material weren't strong enough to withstand biting forces, especially in back teeth. Years ago, all-metal crowns were most often used until the development of a hybrid porcelain crown with an inner metal substructure for strength. In recent years stronger all-porcelain crowns have risen in popularity. The material type that works best often depends on the tooth to be crowned—all-porcelain may work for a visible front incisor, but a porcelain-metal hybrid might be needed for a back molar.

Level of artistry. While new computer manufacturing systems allow dentists to produce patient crowns in-office, most still require the services and skills of a dental lab technician. The cost difference between crowns usually occurs at this juncture: the more life-like and customized the crown, the more artistry and time required by a technician to produce it. This can increase the cost of the crown.

Limited choices. While you and your dentist want your crown choice to be as individualized and life-like as possible, your dental insurance may limit your options. Many policies only provide benefits for the most basic crown restoration—enough to regain functionality and have an acceptable, but not always the most aesthetic, appearance. To get a higher quality of crown you may have to supplement what your policy and deductible will cover.

Deciding which crown is best will depend on where it will be needed, the level of attractiveness you desire and your insurance and financial comfort level. And your dentist can certainly help guide you to a crown choice that's right for you.

If you would like more information on restorative crown choices, 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 “Porcelain Dental Crowns.”

DontPanicOverYourChildsTeethGrindingbutDoKeepanEyeonIt

First the bad news: Those nightly hair-raising sounds are indeed coming from your child’s bedroom—from your child. It’s the result of them grinding their teeth while they sleep.

But here’s the good news: the only likely harm is a lack of sleep members of your household might experience because of it. Teeth grinding is so prevalent among pre-teen children that many healthcare professionals consider it normal. But that doesn’t mean it can’t become a problem, so it’s worth monitoring.

Teeth grinding is part of a family of dental habits known as bruxism. It involves any involuntary movement of the teeth and jaws outside of their intended functions not associated with chewing, speaking or swallowing. Our main concern with any bruxism is the possibility for generating stronger biting forces than normal that could damage teeth and gums and contribute to jaw joint problems.

Teeth grinding can occur in adulthood, with stress seeming to be the major trigger for it. With children, though, it’s believed to be mainly caused by an immaturity of the child’s neuromuscular process that controls chewing. As this matures, most children will tend to outgrow the habit none the worse for wear.

But there are pediatric cases in which the generated biting forces are strong enough to cause damage. Teeth grinding is also prevalent in children who snore or breathe through their mouths, which could be a sign of a serious health condition called obstructive sleep apnea. And certain medications used to treat depression and attention deficit disorder (ADHD) may also contribute to teeth grinding.

Most of the time we can simply let the habit run its course. If, however, the child begins to experience abnormal tooth wear, headaches, jaw pain or other issues believed caused by teeth grinding, we may need to intervene. This could include a plastic night guard the child wears during sleep that prevents the teeth from making solid contact during grinding episodes. And children with signs of airway obstruction should be evaluated by an ear, nose and throat specialist.

It can be irritating or even distressing. But your child’s teeth grinding doesn’t mean you should be alarmed—only that you should keep your eye on it.

PopStarDemiLovatoPopsOutJayGlazersTooth

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!

StayAheadofPlaqueBuildupwithEffectiveBrushingandFlossing

The vast majority of teeth and gum problems stem from two dental diseases: dental caries (tooth decay) and periodontal (gum) disease. But although these dental diseases are all too common in our society, there’s a good chance you can prevent them from harming your own dental health.

That’s because we know the primary cause for both of them—dental plaque, a thin film of bacteria and food particles that can build up on tooth surfaces usually as a result of poor oral hygiene. Remove this plaque build-up daily and you dramatically decrease your risk for disease.

The primary way to do this is with a daily habit of brushing and flossing. While regular dental cleanings remove plaque and tartar (calcified plaque) from hard to reach places, it’s your regular practice that removes the bulk of daily buildup. Interrupting plaque buildup helps keep disease-causing bacteria at bay.

That also means performing these two hygiene tasks thoroughly. For example, you should brush all tooth surfaces, especially in the rear and along the entire gum line (a complete brushing should take at least 2 minutes). And by the way, “thorough” doesn’t mean “aggressive”—a gentle circular motion is all you need. If you scrub too hard, you run the risk over time of damaging your gums.

And while many people discount flossing as a hard and unpleasant task, it’s still necessary: at least half of the plaque in your mouth accumulates between the teeth where brushing can’t reach effectively. If you find flossing too difficult, you can take advantage of tools to make the task easier. A floss threader will make it easier to get floss through your teeth; you could also use an oral irrigator, a device that emits a pressurized spray of water to loosen and flush away some plaque.

Along with dental visits at least twice a year, daily brushing and flossing is the best way to reduce your risk of both tooth decay and gum disease. Avoiding these two diseases will help ensure your smile is attractive and healthy throughout your life.
