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.

Chipped a tooth? Don't beat yourself up—this type of dental injury is quite common. In fact, you probably have a favorite celebrity who has chipped one or more of their teeth. The list is fairly long.
Some chipped a tooth away from the limelight, such as Tom Cruise (a hockey puck to the face as a teen), Jim Carrey (roughhousing on the playground) and Paul McCartney (a sudden stop with a moped). Others, though, chipped a tooth while “on the job.” Taylor Swift, Hillary Duff and Jennifer Lopez have all chipped a tooth on stage with a microphone. And chipped teeth seem to be an occupational hazard among professional athletes like former NFL star, Jerry Rice.
Since smiles are an indispensable asset to high-profile celebrities, you can be sure these stars have had those chipped teeth restored. The good news is the same procedures they've undergone are readily available for anyone. The two most common restorations for chipped teeth are dental bonding and veneers.
The least invasive way to fix a chipped tooth is bonding with a material known as composite resin. With this technique, resin is first mixed to match the tooth color and then applied to the chipped area or applied in layers of color to get just the right look. After a bit of shaping, curing and adjustment, we're done—you can walk out with a restored tooth in one visit.
Bonding works well with slight to moderate chips, but it could be less durable when there is more extensive damage. For that, you may want to consider porcelain veneers. Veneers are thin wafers of dental porcelain that are bonded to the front of teeth to mask blemishes like stains, slight gaps or, yes, chips. Veneers can be so lifelike that you won't be able to tell the veneered tooth from your other teeth. They are fashioned to match the color and shape of an individual's teeth. Because of the time and design detail involved, veneers are more expensive than bonding, yet still within an affordable range for many.
Teeth require some alteration before applying traditional veneers because otherwise the teeth can appear bulky when the veneer is bonded to the existing tooth. To compensate, we remove a little of the tooth enamel. Because this loss is permanent, you'll need to wear veneers or have some other form of restoration for the tooth from then on. For many people, though, that's a small price to pay for a smile without chips.
Your first step to repairing a chipped tooth is to come in for an examination. From there, we'll recommend the best option for your situation. And regardless of which, bonding or veneers, we can change your smile for the better.

Say “bacteria,” especially in the same sentence with “disease” or “infection,” and you may trigger an immediate stampede for the hand sanitizer. The last thing most people want is to come in contact with these “menacing” microorganisms.
If that describes you, however, you’re too late. If you’re of adult age, there are already 100 trillion of these single-celled organisms in and on your body, outnumbering your own cells 10 to 1. But don’t panic: Of these 10,000-plus species only a handful can cause you harm—most are either harmless or beneficial, including in your mouth.
Thanks to recent research, we know quite a bit about the different kinds of bacteria in the mouth and what they’re doing. We’ve also learned that the mouth’s microbiome (the interactive environment of microscopic organisms in a particular location) develops over time, especially during our formative years. New mothers, for example, pass on hundreds of beneficial species of bacteria to their babies via their breast milk.
As our exposure to different bacteria grows, our immune system is also developing—not only fighting bacteria that pose a threat, but also learning to recognize benevolent species. All these factors over time result in a sophisticated, interrelated bacterial environment unique to every individual.
Of course, it isn’t all sweetness and light in this microscopic world. The few harmful oral bacteria, especially those that trigger tooth decay or periodontal (gum) disease, can cause enormous, irreparable damage to the teeth and gums. It’s our goal as dentists to treat these diseases and, when necessary, fight against harmful microorganisms with antibacterial agents and antibiotics.
But our growing knowledge of this “secret world” of bacteria is now influencing how we approach dental treatment. A generalized application of antibiotics, for example, could harm beneficial bacteria as well as harmful ones. In trying to do good we may run the risk of disrupting the mouth’s microbiome balance—with adverse results on a patient’s long-term oral health.
The treatment strategies of the future will take this into account. While stopping dental disease will remain the top priority, the treatments of the future will seek to do it without harming the delicate balance of the mouth’s microbiome.

What's the most successful tooth replacement available today? By far, it's the dental implant. Surgically placed in-office by Dr. Geetha Sripathi at Elite Smiles in Morrisville, dental implants mimic real teeth in appearance and function. Plus, they improve jaw bone density and size, a wonderful therapeutic benefit.
Frequently asked questions about dental implants
What does a dental implant look like?
A dental implant is a titanium screw or cylinder which your dentist inserts into the jaw bone. The implant replaces your natural tooth root and actually bonds with the bone through something called osseointegration. On this firm foundation, your Dr. Sripathi attaches a metal abutment, or post, and a custom-crafted porcelain crown.
Why is a dental implant superior to a bridge or partial denture?
A dental implant is the only tooth replacement which replaces a missing tooth from the root on up. It improves bone size, shape and strength every time you bite and chew on it. Dental implants stay in place for years, and they need no denture adhesive or clasps to anchor them.
Do I need to see a specialist for my procedure?
Dr. Sripathi performs the entire implant treatment--from initial examination and X-rays to implant placement and restoration--at Elite Smiles in Morrisville. She uses multiple dental implants for patients requiring more extensive tooth replacement.
Is the implant surgery comfortable?
Locally-injected numbing medication takes care of any discomfort during the procedure. Afterwards, you may need over-the-counter acetaminophen or ibuprofen at home for a few days to resolve minor residual soreness.
How do I know dental implants are right for my situation?
Dr. Sripathi meticulously evaluates her patients to determine if dental implants are the proper tooth replacements for their individual needs and preferences. Special three-dimensional imaging shows her if you have adequate bone structure to support implants. Also, the dentist reviews your medical history. Most teens and adults are healthy enough for dental implants. However, diabetes, immune deficiencies, cancer treatment, alcohol abuse and pregnancy often prohibit or postpone implant placement.
How long do dental implants last?
The American College of Prosthodontists reports that dental implants last a lifetime when you brush and floss them carefully and see your dentist for routine cleanings and check-ups. Success rates for implant procedures are up to 95 percent.

To have a beautiful, healthy smile you’ll need to keep those pearly whites clean and plaque-free. Good dental hygiene, though, isn’t a solo act: It’s a duet best performed by you and your dental health provider. While you’re responsible for brushing and flossing every day, your dental hygienist gives your teeth a thorough cleaning every six months (or more). The American Dental Hygienists Association commemorates every October as National Dental Hygiene Month to recognize both the importance of hygiene and the professionals who assist you in keeping your teeth as clean as possible.
The focus for this emphasis on brushing, flossing and professional cleaning? A slick, slimy substance called dental plaque. This thin film of bacteria and food particles builds up on tooth surfaces after eating and gives rise to infections that cause tooth decay and gum disease. And it doesn’t take long without proper brushing and flossing, for a gum infection called gingivitis to start in only a matter of days. Daily hygiene reduces your risk of that happening: Brushing removes plaque from the broad, biting surfaces of the teeth, while flossing takes care of the areas between teeth that brushing can’t access.
So, if you can remove most of the plaque yourself, why see a dental hygienist? For two reasons: First, while daily hygiene takes care of the lion’s share of plaque, it’s difficult to clear away all of it. Over time, even a small amount of missed plaque can increase your disease risk. However, a professional cleaning that uses special hand tools and ultrasonic equipment can easily clean away this leftover plaque.
Second, some of the soft plaque can interact with saliva to form a hardened, calcified form called calculus or tartar. It can harbor bacteria just like the softer version, and it’s next to impossible to dislodge with brushing and flossing. Again, a trained hygienist with the right tools can effectively break up and remove calculus.
There are also additional benefits that come from regular dental visits to your hygienist. For one, hygienists can provide practical instruction and tips to help you brush and floss more effectively. And, after cleaning your teeth, they can point out areas with heavy plaque and calculus deposits. That can help you focus more of your future brushing and flossing efforts on those areas.
So, a shout-out to all the dental hygienists out there: These dedicated professionals work hard to keep your teeth clean. And a big high-five to you, too: Without your daily commitment to brushing and flossing, your smile wouldn’t be as beautiful—and healthy.
