Fluoride is a critical weapon in the war against tooth decay. But this natural chemical proven to strengthen tooth enamel has also aroused suspicion over the years that it might cause health problems.
These suspicions have led to rigorous testing of fluoride's safety. And the verdict from decades of research? We've found only one verifiable side effect, a condition called enamel fluorosis. Caused by too much fluoride present in the body, enamel fluorosis produces white streaks and patches on teeth, and can develop into darker staining and pitting in extreme cases. But other than having an unattractive appearance, the teeth remain sound and healthy.
Fortunately, you can reduce the risk of fluorosis by limiting fluoride exposure to within recommended limits. Fluoride can show up in processed foods and other substances, but the two sources you should focus on most are oral hygiene products and fluoridated drinking water.
Dentists highly recommend using toothpaste with fluoride to fight tooth decay. But be careful how much your family uses, especially younger members. An infant only needs a slight smear of toothpaste on their brush for effective hygiene. At around age 2, you can increase the amount to about the size of a vegetable pea.
As to drinking water, most utilities add fluoride to their supply. If yours does, you can find out how much they add by calling them or visiting cdc.gov ("My Water's Fluoride"), where you can also learn more about recommended levels of fluoridation. If you think it's excessive, you can switch to water labeled "de-ionized," "purified," "demineralized," or "distilled," which contain little to no added fluoride.
Even if your fluoridated water is within recommended levels, you may wish to take extra precautions for infants nursing with formula. If possible, use "ready-to-feed" formula, which usually contains very low amounts of fluoride if any. If you're using the powdered form, use only water with the aforementioned labeling for mixing.
Before making any drastic changes that might affect your family's fluoride intake, consult with your dentist first. And be sure you're keeping up regular dental visits—your dentist may be able to detect any early signs of fluorosis before it becomes a bigger problem.

The movie Bohemian Rhapsody celebrates the iconic rock band Queen and its legendary lead vocalist, Freddie Mercury. But when we see pictures of the flamboyant singer, many fans both old and new may wonder—what made Freddie’s toothy smile look the way it did? Here’s the answer: The singer was born with four extra teeth at the back of his mouth, which caused his front teeth to be pushed forward, giving him a noticeable overbite.
The presence of extra teeth—more than 20 primary (baby) teeth or 32 adult teeth—is a relatively rare condition called hyperdontia. Sometimes this condition causes no trouble, and an extra tooth (or two) isn’t even recognized until the person has an oral examination. In other situations, hyperdontia can create problems in the mouth such as crowding, malocclusion (bad bite) and periodontal disease. That’s when treatment may be recommended.
Exactly what kind of treatment is needed? There’s a different answer for each individual, but in many cases the problem can be successfully resolved with tooth extraction (removal) and orthodontic treatment (such as braces). Some people may be concerned about having teeth removed, whether it’s for this problem or another issue. But in skilled hands, this procedure is routine and relatively painless.
Teeth aren’t set rigidly in the jawbone like posts in cement—they are actually held in place dynamically by a fibrous membrane called the periodontal ligament. With careful manipulation of the tooth, these fibers can be dislodged and the tooth can be easily extracted. Of course, you won’t feel this happening because extraction is done under anesthesia (often via a numbing shot). In addition, you may be given a sedative or anti-anxiety medication to help you relax during the procedure.
After extraction, some bone grafting material may be placed in the tooth socket and gauze may be applied to control bleeding; sutures (stitches) are sometimes used as well. You’ll receive instructions on medication and post-extraction care before you go home. While you will probably feel discomfort in the area right after the procedure, in a week or so the healing process will be well underway.
Sometimes, dental problems like hyperdontia need immediate treatment because they can negatively affect your overall health; at other times, the issue may be mainly cosmetic. Freddie Mercury declined treatment because he was afraid dental work might interfere with his vocal range. But the decision to change the way your smile looks is up to you; after an examination, we can help you determine what treatment options are appropriate for your own situation.

Today's dental restorations are truly amazing. Not only are they life-like and functional, they can endure for many years a hostile environment of bacteria, acid and heavy biting forces.
Even so, you'll still need to take care of your restorations to help them last. Here's how to extend the life of 3 common forms of dental work.
Fillings. We use fillings, both metal amalgam and tooth-colored materials, to repair holes or cavities in teeth caused by tooth decay. Although strong, dental fillings can break if you subject them to abnormally high biting force (like chewing ice). There's also a chance that if a slight separation occurs between the filling and tooth, bacteria can take up residence and reignite the decay process. To prevent this, practice a daily regimen of oral hygiene to clean away bacterial plaque—and reduce sugar in your diet, a prime food source for bacteria.
Veneers. Usually made of thin porcelain, veneers are bonded to the front of teeth to mask chips, stains, gaps or other blemishes. But although they're strong, veneers aren't immune to damage. Habits like biting nails, the aforementioned ice chewing or unconsciously grinding your teeth could cause a chipped veneer. And if periodontal (gum) disease causes your gums to recede, the exposed part of the tooth may look noticeably darker than the veneer. To protect your veneers and their appearance, avoid habits like ice chewing, and seek treatment for teeth grinding and dental disease.
Bridgework. Bridges are used to replace one or more missing teeth. Traditional bridges use the natural teeth on either side of the gap to support the bridge; for a single missing tooth, implants are a preferable option because they don't require permanently altering the neighboring teeth to support it. With either option, though, you should brush and floss around the restoration to reduce the risk of dental disease. Infections like gum disease or tooth decay could eventually weaken the bridge's supporting teeth or gum disease can damage an implant's gum and bone support.
With any dental restoration, be sure to practice daily oral hygiene, eat a nutritious, low-sugar diet, and see your dentist regularly for cleanings and checkups. Taking care of your dental work will help it take care of you for a long time to come.
Dental veneers are a great way to transform a smile without the expense or effort often required of other restorations. These thin layers of dental material adhere to the front of teeth as a "mask" to cover chips, heavy staining or other blemishes.
Still, veneers require attention to detail for a successful outcome. Here's a step-by-step look at changing your dental appearance with veneers.
Step 1: Considering your options. While most veneers are made of dental porcelain, composite resin materials are increasingly popular. Although more prone to chipping or staining, composite veneers don't require a dental lab for fabrication. Another option, depending on your dental situation, are ultra-thin veneers that require little to no tooth preparation. Your dentist will help you decide which options are best for you.
Step 2: "Test driving" your new smile. We can help you "see" your future smile with special software that creates a computer image of your teeth with the planned veneers. We can also use composite material to fabricate a "trial smile" to temporarily place on your teeth that can give you the feel as well as the look of your future smile.
Step 3: Preparing your teeth. Unless you're getting no-prep veneers, we'll need to modify your teeth before attaching veneers. Although only 0.3 to 0.7 millimeters thick, veneers can still appear bulky on unprepared teeth. They'll look more natural if we first remove a small amount of enamel. A word of caution, though: although slight, this enamel removal permanently alters your teeth that will require them to have some form of restoration from then on.
Step 4: Attaching your new veneers. After the planning phase (which includes color matching to blend the veneers with the rest of your teeth), a dental lab creates your veneers if you've opted for porcelain. After they're delivered, we'll clean and etch the teeth with a mild acidic gel to increase the bonding effect. We'll then permanently attach the veneers to your teeth with a very thin but ultra-strong resin luting cement that creates a unified bond between the veneers and teeth.
Following these steps is the surest way to achieve a successful outcome. With due care you're sure to enjoy the effects for a long time to come.

We can do a great many things to preserve diseased teeth, from filling cavities to crowning damaged but still viable teeth to protect them and restore their attractiveness. But there may come a point where continued treatment just isn't worth it, and it may be time to remove and replace your troubled teeth.
Dental implants have become the premier restoration for missing teeth. But they have some anatomical limitations and may not work for some situations like excessive bone loss or close nerve proximity. And while a removable partial denture is a solid option, perhaps you'd rather have a fixed solution.
You might then want to consider a fixed bridge to replace one or more missing teeth. This tried and true option has been a mainstay in dentistry for several decades; and while implants may have surpassed them in popularity, they're still available and effective as a restorative option.
A traditional fixed bridge is composed of three or more life-like crowns that are fused together like pickets in a fence. The crown or crowns in the middle fill the empty tooth space; the outside crowns fit over and are bonded to the natural teeth on either side of the empty space to support the bridge. These natural teeth must be reduced in size to accommodate the crowns to fit over them.
Depending on how many teeth are missing, fixed bridges can be a more affordable alternative to dental implants and can achieve life-like results in both form and dental function. But the alterations required for the supporting teeth are permanent and can weaken them. The interface between the natural teeth and the bridge crowns has a higher risk of decay and periodontal disease, so you'll need to be extra vigilant with daily hygiene and regular dental cleanings and checkups.
And even though implants can be more expensive in the short-term, they typically have better durability and less maintenance costs than other restorations. Over the long-term, an implant restoration might actually incur less cost than a fixed bridge.
Still, a fixed bridge can be an effective way to replace missing teeth. Depending on your finances and your overall dental health, a bridge could help you regain an attractive smile.
