Teeth lost to tooth decay can have devastating consequences for a child’s dental health. Not only can it disrupt their current nutrition, speech and social interaction, it can also skew their oral development for years to come.
Fortunately, we have a number of preventive tools to curb decay in young children. One of the most important of these, dental sealants, has been around for decades. We apply these resin or glass-like material coatings to the pits and crevices of teeth (especially molars) to help prevent the buildup of bacterial plaque in areas where bacteria tend to thrive.
Applying sealants is a simple and pain-free process. We first brush the coating in liquid form onto the teeth’s surface areas we wish to protect. We then use a special curing light to harden the sealant and create a durable seal.
So how effective are sealants in preventing tooth decay? Two studies in recent years reviewing dental care results from thousands of patients concluded sealants could effectively reduce cavities even four years after their application. Children who didn’t receive sealants had cavities at least three times the rate of those who did.
Sealant applications, of course, have some expense attached to them. However, it’s far less than the cost for cavity filling and other treatments for decay, not to mention future treatment costs resulting from previous decay. What’s more important, though, is the beneficial impact sealants can have a child’s dental health now and on into adulthood. That’s why sealants are recommended by both the American Dental Association and the American Academy of Pediatric Dentistry.
And while sealants are effective, they’re only one part of a comprehensive strategy to promote your child’s optimum dental health. Daily brushing and flossing, a “tooth-friendly” diet and regular dental cleanings and checkups are also necessary in helping to keep your child’s teeth healthy and free of tooth decay.
If you think gum disease only happens to the other guy (or gal), think again. If you’re over 30 you have a 50-50 chance for an infection. After 65 the risk climbs to 70 percent.
Fortunately, we can effectively treat most cases of gum disease. But depending on its severity, treatment can involve numerous intensive sessions and possible surgery to bring the disease under control. So, why not prevent gum disease before it happens?
First, though, let’s look at how gum disease most often begins—with dental plaque, a thin film of bacteria and food particles built up on teeth and gum surfaces. If plaque isn’t consistently removed through daily brushing and flossing, it doesn’t take long—just a few days—for the bacteria to infect the gums.
While it’s not always easy to detect gum disease early on, there are signs to look for like red, swollen and tender gums that bleed easily when you brush or floss, and bad breath or taste. The infection is usually more advanced if you notice pus-filled areas around your gums or loose teeth. If you see any of these (especially advanced signs like loose teeth) you should contact us as soon as possible.
Obviously, the name of the game with prevention is stopping plaque buildup, mainly through daily brushing and flossing. Technique is the key to effectiveness, especially with brushing: you should gently but thoroughly scrub all tooth surfaces and around the gum line, coupled with flossing between teeth.
To find out how well you’re doing, you can rub your tongue along your teeth after you brush and floss—you should feel a smooth, almost squeaky sensation. You can also use plaque-disclosing agents that dye bacterial plaque a particular color so you can easily see surface areas you’ve missed. You can also ask us for a “report card” on how well you’re doing during your next dental visit.
Dental visits, of course, are the other essential part of gum disease prevention—at least every six months (or more, if we recommend) for cleaning and checkups. Not only will we be able to remove hard-to-reach plaque and tartar, we’ll also give your gums a thorough assessment. By following this prevention regimen you’ll increase your chances of not becoming a gum disease statistic.

Your child’s dental care wouldn’t be the same without x-ray imaging. It’s one of our best tools for finding and treating tooth decay.
But since x-rays emit radiation, is your child in any danger when they’re exposed?
X-rays, an invisible form of electromagnetic energy, will form images on exposed film after passing through the body. Because it takes longer for x-rays to pass through dense tissue like teeth and bones, the corresponding areas appear lighter on the film than less dense tissue like the gums. We can detect decay because the diseased tooth structure is less dense and thus appears darker against healthier tooth structure.
The downside of x-rays, though, is the radiation they emit could potentially alter cell structure and increase the risk of future cancer, especially with children. That’s why we follow a principle known as ALARA when using x-ray imaging. ALARA is an acronym for “as low as reasonably achievable,” meaning the doses for an x-ray session will be as low as possible while still gaining the most benefit.
Advances in technology, particularly the development of digital processing, has helped reduce the amount of radiation exposure. We’re also careful with what types of x-rays we use. The most common type is the bitewing, a device with the film attached to a long piece of plastic that the child holds in their mouth while biting down.
Depending on the number of our patient’s teeth, we can usually get a comprehensive view with two to four bitewings. A typical bitewing session exposes them to less radiation than what they’re receiving from natural environmental background sources each day.
Keeping the exposure as low and as less frequent as possible greatly reduces health risks while still getting the full benefit of early decay detection. Still, if you have concerns about your child’s x-ray exposure, we’ll be happy to discuss our approach and all the precautions we take using x-ray imaging.

Everyone has to face the music at some time — even John Lydon, former lead singer of The Sex Pistols, arguably England’s best known punk rock band. The 59-year old musician was once better known by his stage name, Johnny Rotten — a brash reference to the visibly degraded state of his teeth. But in the decades since his band broke up, Lydon’s lifelong deficiency in dental hygiene had begun to cause him serious problems.
In recent years, Lydon has had several dental surgeries — including one to resolve two serious abscesses in his mouth, which left him with stitches in his gums and a temporary speech impediment. Photos show that he also had missing teeth, which, sources say, he opted to replace with dental implants.
For Lydon (and many others in the same situation) that’s likely to be an excellent choice. Dental implants are the gold standard for tooth replacement today, for some very good reasons. The most natural-looking of all tooth replacements, implants also have a higher success rate than any other method: over 95 percent. They can be used to replace one tooth, several teeth, or an entire arch (top or bottom row) of teeth. And with only routine care, they can last for the rest of your life.
Like natural teeth, dental implants get support from the bone in your jaw. The implant itself — a screw-like titanium post — is inserted into the jaw in a minor surgical operation. The lifelike, visible part of the tooth — the crown — is attached to the implant by a sturdy connector called an abutment. In time, the titanium metal of the implant actually becomes fused with the living bone tissue. This not only provides a solid anchorage for the prosthetic, but it also prevents bone loss at the site of the missing tooth — which is something neither bridgework nor dentures can do.
It’s true that implants may have a higher initial cost than other tooth replacement methods; in the long run, however, they may prove more economical. Over time, the cost of repeated dental treatments and periodic replacement of shorter-lived tooth restorations (not to mention lost time and discomfort) can easily exceed the expense of implants.
That’s a lesson John Lydon has learned. “A lot of ill health came from neglecting my teeth,” he told a newspaper reporter. “I felt sick all the time, and I decided to do something about it… I’ve had all kinds of abscesses, jaw surgery. It costs money and is very painful. So Johnny says: ‘Get your brush!’”
We couldn’t agree more. But if brushing isn’t enough, it may be time to consider dental implants. If you would like more information about dental implants, please call our office to schedule a consultation.

If you press your tongue against your teeth, unless something is badly wrong they won't budge. In fact, your teeth are subjected to a fair amount of pressure each day as you chew and eat, and yet they remain firmly in place.
But there's a deeper reality—your teeth do move! No, it's not a paradox—the gum and bone tissues that hold your teeth in place allow for slight, imperceptible changes in the teeth's position. Their natural ability to move is also the basis for orthodontics. Here are 3 more facts you may not know about your teeth's natural ability to move.
Teeth are always on the move. Teeth are held firmly within the jawbone by an elastic gum tissue called the periodontal ligament and a thin layer of bony-like material called cementum. In response to pressure changes, though, the bone dissolves on the side of the teeth in the direction of pressure and then rebuilds behind it, solidifying the teeth's new position, a process that happens quite slowly and incrementally. And it will happen for most of us—some studies indicate more than 70% of people will see significant changes in their bite as they age.
Orthodontics works with the process. Orthodontic appliances like braces or clear aligners apply targeted pressure in the direction the orthodontist intends the teeth to move—the natural movement process does the rest. In the case of braces, a thin metal wire is laced through brackets bonded to the front of the teeth and then anchored, typically to the back teeth. The orthodontist incrementally tightens the wire against its anchors over time, encouraging tooth movement in response to the pressure. Clear aligners are a series of removable trays worn in succession that gradually accomplish the same outcome.
Watch out for the rebound. That nice, straight smile you've gained through orthodontics might not stay that way. That's because the same mechanism for tooth movement could cause the teeth to move back to their former positions, especially right after treatment. To avoid this outcome, patients need to wear a retainer, an appliance that holds or "retains" the teeth in their new positions. Depending on their individual situations and age, patients may have to wear a retainer for a few months, years or from then on.
