WhyitsWorththeEfforttoSaveaProblemBabyTooth

There are usually two moments when primary (“baby”) teeth generate excitement in your family: when you first notice them in your child’s mouth, and when they come out (and are headed for a rendezvous with the “tooth fairy”!).

Between these two moments, you might not give them much thought. But you should—although primary teeth don’t last long, they play a pivotal role in the replacing permanent teeth’s long-term health.

This is because a primary tooth is a kind of guide for the permanent one under development in the gums. It serves first as a “space saver,” preventing nearby teeth from drifting into where the permanent tooth would properly erupt; and, it provides a pathway for the permanent tooth to travel during eruption. If it’s lost prematurely (from injury or, more likely, disease) the permanent tooth may erupt out of position because the other teeth have crowded the space.

That’s why we try to make every reasonable effort to save a problem primary tooth. If decay, for example, has advanced deep within the tooth pulp, we may perform a modified root canal treatment to remove the diseased tissue and seal the remaining pulp from further infection. In some circumstances we may cap the tooth with a stainless steel crown (or possibly a white crown alternative) to protect the remaining structure of the tooth.

Of course, even the best efforts can fall short. If the tooth must be removed, we would then consider preserving the empty space with a space maintainer. This orthodontic device usually takes the form of a metal band that’s cemented to a tooth on one side of the empty space with a stiff wire loop soldered to it that crosses the space to rest against the tooth on the other side. The wire loop prevents other teeth from crowding in, effectively “maintaining” the space for the permanent tooth.

Regular dental visits, plus your child’s daily brushing and flossing, are also crucial in preventing primary teeth from an “early departure.” Keeping them for their full lifespan will help prevent problems that could impact your child’s dental health future.

If you would like more information on the right care approach for primary teeth, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Importance of Baby Teeth.”

ThisNovemberBecomeaNon-Smoker

What does November make you think of? Pumpkins? Turkeys? Dry leaves and frosty mornings? How about cigarette butts?

If you’re wondering about the last item, remember that November 15 is the date of the Great American Smokeout—a day set aside for those who want to take the first steps toward quitting the tobacco habit. While the percentage of smokers in the U.S. has dropped to less than 16% in recent years, according to the American Cancer Society there are still some 38 million Americans who smoke cigarettes. Smoking causes over 480,000 deaths every year, and is the leading preventable cause of death in the U.S.

Even if it doesn’t kill you, the effects of tobacco use can be devastating to your entire body—including your mouth. Whether you smoke cigarettes or use chewing tobacco, your risk of oral cancer is greatly increased, as is your chance of developing periodontal (gum) disease. What’s more, smoking can mask the symptoms of gum disease, so your condition is actually worse than it appears. Severe gum disease is one reason why smokers tend to lose more teeth than non-smokers.

In addition, because smoking interferes with the natural healing process, smokers have a much greater chance of dental implant failure. Tobacco use also can lead to increased amounts of plaque, which results in tooth decay and other oral health problems. It also stains your teeth, reduces your senses of smell and taste, and gives you bad breath.

Ready to quit yet? If so, there are lots of resources to help you on the road to a healthier life. The American Cancer Society, sponsor of the Smokeout, can help you make a plan to quit tobacco—and stay off it. It’s not easy, but over a million Americans do it every year. See their website for more information, plans and tips on quitting. Your health care professionals are also a great source of information and help when it’s time to get off the tobacco habit. Feel free to ask us any questions you may have.

And here’s the good news: The moment you quit, your body begins to recover from the effects of tobacco use. In just one year, you’ll have cut your risk of heart attack and stroke in half. After 5 to 15 years, your risk of stroke, coronary heart disease, and several other conditions is the same as someone who has never smoked.

If you have questions about smoking and oral health, please contact our office or schedule a consultation. To learn more, read the Dear Doctor magazine articles “Smoking and Gum Disease” and “Dental Implants and Smoking.”

MargotRobbieKnowsAGreatSmileIsWorthProtecting

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.

“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”

Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.

Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.

A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.

Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.

So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

If you have questions about teeth grinding or orthodontic retainers, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Teeth Grinding” and “The Importance of Orthodontic Retainers.”

LessisBetterthe21stCenturyApproachtoToothDecayTreatment

For over a century dentists treated tooth decay by removing both diseased portions of the tooth and healthy structure deemed at risk for future decay. In the 1970s, though, a new approach emerged, known as Minimally Invasive Dentistry (MID). This practice protocol attempts to preserve as much of the healthy structure as possible.

Before MID, dentists followed a decay treatment protocol developed in the 19th Century. A part of this became known as extension for prevention calling for dentists to remove healthy structure considered vulnerable to decay. Besides reducing the tooth's volume, this practice also resulted in, by today's standards, larger than necessary fillings.

It was thought that removing this additional material would make it easier to clean bacterial plaque, the source of decay, but later, research showed the practice couldn't guarantee the teeth wouldn't be reinfected.

Since then we've learned a lot more about teeth and have developed new ways to detect decay at earlier stages. X-ray imaging, for example, has transitioned largely from film to digital technology, providing more detailed images at greater magnification. This, along with laser fluorescence and infrared cameras, has made it easier to detect the first tiny stages of decay.

We can also limit tooth decay damage by boosting enamel strength with fluoride applications and sealants or reducing decay-causing bacteria with anti-bacterial rinses. We've also seen advancement in techniques like air abrasion that remove decayed tooth material while leaving more healthy structure intact better than using a traditional dental drill.

Restoring teeth after treatment has also improved. While dental metal amalgam is still used for some fillings, the main choice is now composite resin. These new tooth-colored dental materials require less tooth preparation (and thus less material loss) and bond well to the remaining structure, resulting in a stronger tooth.

Following a MID protocol leads to less intervention and less time in the dentist's chair. It also means preserving more of a natural tooth, an important aim in promoting long-lasting dental health.

InflammationtheLinkBetweenGumDiseaseandCardiovascularDisease

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.
