Fluoride has been proven to strengthen tooth enamel against decay. That’s why it’s not only added to toothpaste and other dental products, but also to drinking water — in nearly three-quarters of U.S. water systems.
While research has eased most serious health questions about fluoride, there remains one moderate concern. Too much fluoride over time, especially in infants and young children, could lead to “enamel fluorosis,” an excess of fluoride in the tooth structure that can cause spotting or streaking in the enamel. While often barely noticeable, some cases of fluorosis can produce dark staining and a pitted appearance. Although not a symptom of disease, fluorosis can create a long-term cosmetic concern for the person.
To minimize its occurrence, children under the age of 9 shouldn’t regularly ingest fluoride above of the recommended level of 0.70 ppm (parts per million). In practical terms, you as a parent should monitor two primary sources of fluoride intake: toothpaste and drinking water.
Young children tend to swallow toothpaste rather than spit it out after brushing, which could result in too much fluoride ingestion if the amount is too great. The American Academy of Pediatric Dentistry therefore recommends a small “smear” of toothpaste for children under two, and a pea-sized amount for children up to age six. Brushing should also be limited to no more than two times a day.
Your child or infant could also take in too much fluoride through fluoridated drinking water, especially if you’re using it to mix infant formula. You should first find out the fluoride levels in your local water system by contacting the utility or the health department. If your system is part of the U.S. Centers for Disease Control and Prevention’s (CDC) “My Water’s Fluoride” program, you may be able to access that information on line at //apps.nccd.cdc.gov/MWF/Index.asp.
If the risk for developing fluorosis in your area is high, you can minimize your infant’s intake with a few recommendations: breastfeed rather than use formula; use “ready-to-feed” formula that doesn’t need mixing and contains lower fluoride levels; and use bottled water specifically labeled “de-ionized,” “purified,” “de-mineralized,” or “distilled.”
Fluoride can be a wonderful adjunct to dental care in reducing risk for tooth decay. Keeping an eye on how much fluoride your child takes in can also minimize the chance of future appearance problems.

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.
Everyone knows that in the game of football, quarterbacks are looked up to as team leaders. That's why we're so pleased to see some NFL QB's setting great examples of… wait for it… excellent oral hygiene.
First, at the 2016 season opener against the Broncos, Cam Newton of the Carolina Panthers was spotted on the bench; in his hands was a strand of dental floss. In between plays, the 2105 MVP was observed giving his hard-to-reach tooth surfaces a good cleaning with the floss.
Later, Buffalo Bills QB Tyrod Taylor was seen on the sideline of a game against the 49ers — with a bottle of mouthwash. Taylor took a swig, swished it around his mouth for a minute, and spit it out. Was he trying to make his breath fresher in the huddle when he called out plays?
Maybe… but in fact, a good mouthrinse can be much more than a short-lived breath freshener.
Cosmetic rinses can leave your breath with a minty taste or pleasant smell — but the sensation is only temporary. And while there's nothing wrong with having good-smelling breath, using a cosmetic mouthwash doesn't improve your oral hygiene — in fact, it can actually mask odors that may indicate a problem, such as tooth decay or gum disease.
Using a therapeutic mouthrinse, however, can actually enhance your oral health. Many commonly available therapeutic rinses contain anti-cariogenic (cavity-fighting) ingredients, such as fluoride; these can help prevent tooth decay and cavity formation by strengthening tooth enamel. Others contain antibacterial ingredients; these can help control the harmful oral bacteria found in plaque — the sticky film that can build up on your teeth in between cleanings. Some antibacterial mouthrinses are available over-the-counter, while others are prescription-only. When used along with brushing and flossing, they can reduce gum disease (gingivitis) and promote good oral health.
So why did Taylor rinse? His coach Rex Ryan later explained that he was cleaning out his mouth after a hard hit, which may have caused some bleeding. Ryan also noted, “He [Taylor] does have the best smelling breath in the league for any quarterback.” The coach didn't explain how he knows that — but never mind. The takeaway is that a cosmetic rinse may be OK for a quick fix — but when it comes to good oral hygiene, using a therapeutic mouthrinse as a part of your daily routine (along with flossing and brushing) can really step up your game.
If you're ready to put the "pizzazz" back into your smile, your dentist may be able to help. It's possible your dull, dingy smile could be transformed with teeth whitening.
Teeth whitening or bleaching is a technique that applies a solution with a bleaching agent (usually up to 35% hydrogen peroxide in an office setting) to the teeth to whiten them. Although there are Do-It-Yourself home whitening kits you can use, there are a few good reasons why you should first consider a whitening procedure in a dental office setting.
To begin with, you should first have your teeth examined by a dentist to determine why they're discolored. Certain foods and beverages we consume or tobacco habits are the usual culprits causing stains on the enamel, the outermost tooth layer. These are the kinds of stains targeted by most whitening solutions.
But the interior of a tooth can also become discolored for reasons like trauma, past dental work or tetracycline use at an early age. If your staining is internal (intrinsic) rather than external (extrinsic) reducing that discoloration will require an invasive procedure only a dentist can perform—a home kit won't be able to do the job.
Another reason for having your teeth whitened by your dentist (even extrinsic staining) involves your time and the degree of brightness you'd like. Because dentists use stronger bleaching solutions (home kits usually use a weaker solution of 10% carbamide peroxide) it takes fewer sessions than home kits to achieve results—and they may last longer. In addition, dentists have more control over the level of brightness to match your expectations of a more subdued, natural look or a dazzling "Hollywood" smile.
A dentist can also help you navigate special circumstances like matching and managing natural teeth whiteness with dental restorations (which don't bleach) or special whitening situations like a single discolored tooth.
Even if you eventually decide to go the home kit route, consulting with a dentist first can still prove helpful. You'll get expert advice on products, tips on how to apply them and how to prolong the whitening effect. Whichever way you go, home kit or dentist, you can gain a brighter, more confident smile with teeth whitening.

One of the most important revolutions in healthcare in recent decades is the increasing use of lasers. Now, laser technology is making a showing in dental care for the treatment of periodontal (gum) disease.
Lasers (an acronym for "Light Amplification by Stimulated Emission of Radiation") narrowly focus and amplify light within a small area. First developed in the early 1960s, laser technology rapidly advanced in the ensuing decades with more compact and precise devices that were eventually safe and effective for many types of medical procedures. Its remarkable features are now available for the primary focus of gum disease treatment—removing bacterial plaque.
Plaque is a thin, built-up film of bacteria and food particles on tooth and gum surfaces that serves as a haven for the bacteria that cause gum disease. The continuing presence of plaque and calculus (tartar) enables the infection to thrive and advance within the gum tissues, ultimately damaging them along with supporting bone. As the tissues weaken and bone volume diminishes, the teeth are at greater risk for loss.
It's necessary, therefore, first and foremost to remove all detectable plaque and calculus to stop the infection. This is traditionally done with special hand tools called scalers used to manually remove plaque, or with ultrasonic equipment that vibrates plaque loose to be flushed away with water. These procedures can take numerous sessions and may result in some minor post-procedural discomfort and bleeding during the cleaning.
But lasers specifically designed for plaque removal can minimize tissue damage and resulting discomfort. Because the particular laser light used reacts only with plaque and diseased tissue, it can remove them without disturbing nearby healthy tissue usually more efficiently than traditional scaling. Dentists who've used the technology frequently report less bleeding and higher patient satisfaction.
But before lasers for gum disease treatment are widely adopted, the procedure must undergo further scrutiny. Reports from dentists notwithstanding, not enough research studies have been performed to date that meet the necessary scientific criteria. But if the evidence so far from the field holds up, it's quite possible lasers will one day become a regular part of dental practice for treating gum disease.
