A couple of years ago the Associated Press published an article claiming the health benefits of flossing remained unproven. The article cited a number of studies that seemed to conclude the evidence for the effectiveness of flossing in helping to prevent dental disease as “weak.”
As you can imagine, dental providers were a bit chagrined while flossers everywhere threw away their dental floss and happily declared their independence from their least favorite hygiene task. It would have seemed the Age of Flossing had gone the way of the dinosaurs.
But, the demise of flossing may have been greatly exaggerated. A new study from the University of North Carolina seems to contradict the findings cited in the AP article. This more recent study looked at dental patients in two groups—those who flossed and those who didn’t—during two periods of five and ten years respectively. The new study found conclusively that the flosser group on average had a lower risk of tooth loss than the non-flossers.
While this is an important finding, it may not completely put the issue to rest. But assuming it does, let’s get to the real issue with flossing: a lot of people don’t like it, for various reasons. It can be time-consuming; it can be messy; and, depending on a person’s physical dexterity, difficult to perform.
On the latter, there are some things you can do to make it a less difficult task. You can use a floss threader, a device that makes it easier to thread the floss through the teeth. You can also switch to an oral irrigator or “water flosser,” a pump device that sprays a fine, pressurized stream of water to break up plaque between teeth and flush most of it away. We can also give you tips and training for flossing with just your fingers and thread.
But whatever you do, don’t give up the habit. It may not be your most favorite hygiene task but most dentists agree it can help keep your teeth healthy for the long-term.
Some people are lucky — they never seem to have a mishap, dental or otherwise. But for the rest of us, accidents just happen sometimes. Take actor Jamie Foxx, for example. A few years ago, he actually had a dentist intentionally chip one of his teeth so he could portray a homeless man more realistically. But recently, he got a chipped tooth in the more conventional way… well, conventional in Hollywood, anyway. It happened while he was shooting the movie Sleepless with co-star Michelle Monaghan.
“Yeah, we were doing a scene and somehow the action cue got thrown off or I wasn't looking,” he told an interviewer. “But boom! She comes down the pike. And I could tell because all this right here [my teeth] are fake. So as soon as that hit, I could taste the little chalkiness, but we kept rolling.” Ouch! So what's the best way to repair a chipped tooth? The answer it: it all depends…
For natural teeth that have only a small chip or minor crack, cosmetic bonding is a quick and relatively easy solution. In this procedure, a tooth-colored composite resin, made of a plastic matrix with inorganic glass fillers, is applied directly to the tooth's surface and then hardened or “cured” by a special light. Bonding offers a good color match, but isn't recommended if a large portion of the tooth structure is missing. It's also less permanent than other types of restoration, but may last up to 10 years.
When more of the tooth is missing, a crown or dental veneer may be a better answer. Veneers are super strong, wafer-thin coverings that are placed over the entire front surface of the tooth. They are made in a lab from a model of your teeth, and applied in a separate procedure that may involve removal of some natural tooth material. They can cover moderate chips or cracks, and even correct problems with tooth color or spacing.
A crown is the next step up: It's a replacement for the entire visible portion of the tooth, and may be needed when there's extensive damage. Like veneers, crowns (or caps) are made from models of your bite, and require more than one office visit to place; sometimes a root canal may also be needed to save the natural tooth. However, crowns are strong, natural looking, and can last many years.
But what about teeth like Jamie's, which have already been restored? That's a little more complicated than repairing a natural tooth. If the chip is small, it may be possible to smooth it off with standard dental tools. Sometimes, bonding material can be applied, but it may not bond as well with a restoration as it will with a natural tooth; plus, the repaired restoration may not last as long as it should. That's why, in many cases, we will advise that the entire restoration be replaced — it's often the most predictable and long-lasting solution.
Oh, and one more piece of advice: Get a custom-made mouthguard — and use it! This relatively inexpensive device, made in our office from a model of your own teeth, can save you from a serious mishap… whether you're doing Hollywood action scenes, playing sports or just riding a bike. It's the best way to protect your smile from whatever's coming at it!

It’s been a long road with your braces, but now they’re finally off. Hopefully the first glimpse of your new smile more than made up for the time and effort they required.
But while braces removal is a big milestone, it’s not the end of your treatment—not, that is, if you want to keep that new smile! You’ll now need to wear an appliance called a retainer for a few years or, in some cases, from now on.
Orthodontic retainers are a must after braces for the same reason braces work in the first place—your teeth can move. While the teeth attach to the jawbone via the roots, they’re firmly held in place by an elastic gum tissue network called the periodontal ligament. This tough but elastic tissue lies between the teeth and gums and attaches securely to both with tiny fibers.
While the ligament provides stability, it’s also dynamic—constantly remodeling to allow the teeth to move in response to biting pressure and other mouth factors. Orthodontists use this mechanism when moving teeth to better positions. The braces apply pressure on the teeth in the desired direction and the periodontal ligament responds as the teeth move.
Afterward, however, the ligament can still retain a kind of “muscle memory” for a time of the teeth’s old positions. Free of the pressure once supplied by the braces the teeth have a tendency, especially early on, to “rebound” to where they were.
A retainer helps prevent this by exerting just enough pressure to “retain” the teeth in their new positions. In the beginning this may require wearing the appliance around the clock, but you may be able later to reduce wear time to just a few hours a day. Rebounding is unpredictable, so you should continue to follow your orthodontist’s recommendations on retainer wear.
Wearing a retainer may seem like a drag, but it’s absolutely essential. Being diligent about it will help ensure that the beautiful smile you and your orthodontist worked so hard to obtain stays with you for years to come.

Cardiovascular disease and periodontal (gum) disease are two different conditions with their own set of symptoms and outcomes. But they do share one common element: inflammation. In fact, this otherwise normal defensive response of the body might actually create a link between them.
When tissues become damaged from disease or injury, the body triggers inflammation to isolate them from the rest of the body. This allows these tissues to heal without affecting other tissues. If inflammation becomes chronic, however, it can damage rather than protect the body.
This happens with both cardiovascular disease and gum disease. In the former, low-density lipoproteins (LDL or “bad cholesterol”) in animal fat leave behind remnants that can build up within arteries. This stimulates inflammation of the vessel’s inner linings, which accelerates hardening and increases the risk of heart attack or stroke.
With gum disease, bacteria living in a thin, built-up film of food particles on the teeth called plaque infect the gum tissues, which in turn trigger inflammation. A struggle ensures between the infection and inflammation, causing the gum tissues to weaken and detach from the teeth. Coupled with erosion of the supporting bone, the risk of tooth loss dramatically increases.
Recent research now seems to indicate the inflammatory responses from these two diseases may not occur in isolation. There is evidence that gum inflammation could aggravate inflammation in the cardiovascular system, and vice-versa. The research, though, points to some possible good news: treating inflammation in either disease could have a positive effect on the other.
Making heart-friendly lifestyle changes like losing extra weight (especially around the waist), improving nutrition, and exercising regularly can help reduce LDL and lower the risk of arterial inflammation. Likewise for your gums, daily oral hygiene and visiting the dentist at least twice a year reduces the risk for gum disease. And at the first sign of a gum infection—swollen, reddened or bleeding gums—seeking immediate treatment will stop it and reduce any occurring inflammation.
Taking steps to prevent or reduce inflammation brought on by both of these diseases could improve your health and save your life.

Over the last century effectively treating a decayed tooth has often required removing any decayed structure with drilling and then filling the remaining cavity. While this approach does save teeth that might otherwise be lost, it can also result in a fair amount of healthy structure removed in the process.
But continuing advances in dentistry are now making possible a new approach to tooth decay treatment that preserves as much of the healthy portions of tooth as possible. This new way is often referred to as minimally invasive dentistry (MID).
The primary goal of MID treatment is to intercept and treat decay as early as possible to minimize tooth damage. It begins with helping patients identify their own individual risk factors for decay such as the presence of disease-causing bacteria, the adequacy of their saliva flow, or their lifestyle and dietary habits. We then recommend changes or preventive measures to reduce those risks.
The next step in MID is using various diagnostic technologies to find decay as early as possible. X-rays continue to play a major role, but dentists are also using dental microscopy to magnify the earliest forms of decay. Many also utilize laser fluorescence, infrared photography and optical scanning to further “see” decay difficult to detect with the naked eye.
In regard to treatments, MID adopts the adage “less is more.” If caught early enough, we can encourage the re-mineralization of enamel that acid has eroded with CPP-ACP, a substance acquired from milk, or strengthen teeth with topical fluoride applications. Instead of the dental drill, many dentists now turn to air abrasion for decay removal, equipment that emits a fine stream of abrasive particles that harms less healthy structure than a drill.
And if lasers continue to develop at their current pace, we’ll be able to use this technology to perform much more precise decay treatment than possible with manual instruments. As a result, we’ll be able to treat decayed teeth with less invasive means to preserve as much healthy structure as possible.
As these and other developments continue, MID promises a bright future for preventing and treating tooth decay. As a result, there’ll be less tooth structure loss and more attractive and healthy smiles.
