WisdomTeethWarrantCloseWatchtoAvoidFutureHealthIssues

As permanent teeth gradually replace primary (“baby”) teeth, most will come in by early adolescence. But the back third molars—the wisdom teeth—are often the last to the party, usually erupting between ages 18 and 24, and the source of possible problems.

This is because the wisdom teeth often erupt on an already crowded jaw populated by other teeth. As a result, they can be impacted, meaning they may erupt partially or not at all and remain largely below the gum surface.

An impacted tooth can impinge on its neighboring teeth and damage their roots or disrupt their protective gum attachment, all of which makes them more susceptible to tooth decay or periodontal (gum) disease. Impacted teeth can also foster the formation of infected cysts that create areas of bone loss or painful infections in the gums of other teeth.

Even when symptoms like these aren’t present, many dentists recommend removing the wisdom teeth as a preemptive measure against future problems or disease. This often requires a surgical extraction: in fact, wisdom teeth removal is the most common oral surgical procedure.

But now there’s a growing consensus among dentists that removing or not removing wisdom teeth should depend on an individual’s unique circumstances. Patients who are having adverse oral health effects from impacted wisdom teeth should consider removing them, especially if they’ve already encountered dental disease. But the extraction decision isn’t as easy for patients with no current signs of either impaction or disease. That doesn’t mean their situation won’t change in the future.

One way to manage all these potentialities is a strategy called active surveillance. With this approach, patient and dentist keep a close eye on wisdom teeth development and possible signs of impaction or disease. Most dentists recommend carefully examining the wisdom teeth (including diagnostic x-rays and other imaging) every 24 months.

Following this strategy doesn’t mean the patient won’t eventually have their wisdom teeth removed, but not until there are clearer signs of trouble. But whatever the outcome might be, dealing properly with wisdom teeth is a high priority for preventing future oral health problems.

NBCStarDeliversaMessageaboutthePerfectSmile

Sometimes it seems that appearances count for everything—especially in Hollywood. But just recently, Lonnie Chaviz, the 10-year-old actor who plays young Randall on the hit TV show This Is Us, delivered a powerful message about accepting differences in body image. And the whole issue was triggered by negative social media comments about his smile.

Lonnie has a noticeable diastema—that is, a gap between his two front teeth; this condition is commonly seen in children, but is less common in adults. There are plenty of celebrities who aren’t bothered by the excess space between their front teeth, such as Michael Strahan, Lauren Hutton and Vanessa Paradis. However, there are also many people who choose to close the gap for cosmetic or functional reasons.

Unfortunately, Lonnie had been on the receiving end of unkind comments about the appearance of his smile. But instead of getting angry, the young actor posted a thoughtful reply via Instagram video, in which he said: “I could get my gap fixed. Braces can fix this, but like, can you fix your heart, though?”

Lonnie is raising an important point: Making fun of how someone looks shows a terrible lack of compassion. Besides, each person’s smile is uniquely their own, and getting it “fixed” is a matter of personal choice. It’s true that in most circumstances, if the gap between the front teeth doesn’t shrink as you age and you decide you want to close it, orthodontic appliances like braces can do the job. Sometimes, a too-big gap can make it more difficult to eat and to pronounce some words. In other situations, it’s simply a question of aesthetics—some like it; others would prefer to live without it.

There’s a flip side to this issue as well. When teeth need to be replaced, many people opt to have their smile restored just the way it was, rather than in some “ideal” manner. That could mean that their dentures are specially fabricated with a space between the front teeth, or the crowns of their dental implants are spaced farther apart than they normally would be. For these folks, the “imperfection” is so much a part of their unique identity that changing it just seems wrong.

So if you’re satisfied with the way your smile looks, all you need to do is keep up with daily brushing and flossing, and come in for regular checkups and cleanings to keep it healthy and bright. If you’re unsatisfied, ask us how we could help make it better. And if you need tooth replacement, be sure to talk to us about all of your options—teeth that are regular and “Hollywood white;” teeth that are natural-looking, with minor variations in color and spacing; and teeth that look just like the smile you’ve always had.

Because when it comes to your smile, we couldn’t agree more with what Lonnie Chaviz said at the end of his video: “Be who you want to be. Do what you want to do. Do you. Be you. Believe in yourself.”

FindoutWhatKindofToothStainingyouHaveBeforeSeekingaSolution

Stained teeth can be embarrassing — so much so you may even hesitate to smile. Before you seek out a whitening solution, though, there are a few things you need to know about tooth staining.

Tooth staining is more complex than you might think. There are actually two types: extrinsic, staining from foods and other substances of the outer surface of the enamel; and intrinsic, discoloration deep within a tooth that affects their outward appearance. The latter staining has a number of causes, including the type of dental materials used to fill a tooth, a history of trauma or the use of the antibiotic tetracycline during early tooth development.

There are some noticeable differences between the two types, although an examination is usually necessary to determine which you have. Extrinsic staining tends to be brown, black, or gray, or occasionally green, orange or yellow. Intrinsic staining can be red, pink or, if caused by tetracycline and fluoresced under ultraviolet light, yellow. If only one tooth is discolored it’s most likely intrinsic due to decay in the tooth pulp.

What can be done also depends on which type. Extrinsic staining can be modified through whitening, with either an office application or a home kit (there are differences, so you should consult with us before you decide). It may also be essential to modify your diet by restricting foods and beverages (coffee, wine or tea) known to cause staining and by eliminating tobacco use. You should also practice daily hygiene, including brushing with a toothpaste designed to diminish staining, and regular office cleaning and polishing.

Intrinsic staining can’t be addressed by these methods. Instead, you may need to undergo a procedure where we enter the interior of the tooth and insert a bleaching agent. If this isn’t an option, you can also choose a cosmetic restoration such as a porcelain veneer or crown that will cover the tooth to better match the color of your other teeth.

Dealing with stained teeth begins with a visit to our office to determine what type of discoloration you have and to learn your options. But regardless of what type you have, there is a way to a brighter smile.

If you would like more information on the causes and treatments of tooth staining, 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 “Tooth Staining.”

WhatYouNeedtoKnowtoBuytheRightToothbrush

If there’s one essential tool for protecting your dental health, it’s the humble toothbrush. The basic manual brush with a long, slender handle and short-bristled head is still effective when used skillfully. The market, though, is full of choices, all of them touting their brand as the best.

So how do you choose? You can cut through any marketing hype with a few simple guidelines.

First, understand what you’re trying to accomplish with brushing: removing dental plaque, that thin film of bacteria and food particles on tooth surfaces that’s the main cause of dental disease. Brushing also stimulates gum tissue and helps reduce inflammation.

With that in mind, you’ll first want to consider the texture of a toothbrush’s bristles, whether they’re stiff (hard) or more pliable (soft). You might think the firmer the better for removing plaque, but actually a soft-bristled brush is just as effective in this regard. Stiffer bristles could also damage the gums over the long term.

Speaking of bristles, look for those that have rounded tips. In a 2016 study, less rounded tips increased gum recession in the study’s participants by 30%. You should also look for toothbrushes with different bristle heights: longer bristles at the end can be more effective cleaning back teeth.

As far as size and shape, choose a brush that seems right and comfortable for you when you hold it. For children or people with dexterity problems, a handle with a large grip area can make the toothbrush easier to hold and use.

And look for the American Dental Association (ADA) Seal of Acceptance, something you may have seen on some toothpaste brands. It means the toothbrush in question has undergone independent testing and meets the ADA’s standards for effectiveness. That doesn’t mean a particular brush without the seal is sub-standard—when in doubt ask your dentist on their recommendation.

Even a quality toothbrush is only as effective as your skill in using it. Your dental provider can help, giving you tips and training for getting the most out of your brush. With practice, you and your toothbrush can effectively remove disease-causing plaque and help keep your smile beautiful and healthy.

If you would like more information on what to look for in a toothbrush, 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 “Sizing up Toothbrushes.”

ManageYourOsteoporosisMedicationtoAvoidJawboneProblems

Around 20 million people—mostly women after menopause—take medication to slow the progress of osteoporosis, a debilitating disease that weakens bones. But although effective, some osteoporosis drugs could pose dental issues related to the jawbones.

Osteoporosis causes the natural spaces that lie between the mineral content of bone to grow larger over time. This makes the bone weaker and unable to withstand forces it once could, which significantly increases the risk of fracture. A number of drugs have been developed over time that stop or slow this disease process.

Two of the most prominent osteoporosis drugs are alendronate, known also by its trade name Fosamax™, and denosumab or Prolia™. While originating from different drug families, alendronate and denosumab work in a similar way by destroying specialized bone cells called osteoclasts that break down worn out bone and help dissolve it. By reducing the number of these cells, more of the older bone that would have been phased out lasts longer.

In actuality this only offers a short-term benefit in controlling osteoporosis. The older bone isn’t renewed but only preserved, and will eventually become fragile and more prone to fracture. After several years the tide turns negatively for the bone’s overall health. It’s also possible, although rare, that the bone simply dies in a condition called osteonecrosis.

The jawbones are especially susceptible to osteonecrosis. Forces generated by chewing normally help stimulate jawbone growth, but the medications in question can inhibit that stimulus. As a result the jawbone can diminish and weaken, making eventual tooth loss a real possibility.

Osteonecrosis is most often triggered by trauma or invasive dental procedures like tooth extractions or oral surgery. For this reason if you’re taking either alendronate and denosumab and are about to undergo a dental procedure other than routine cleaning, filling or crown-work, you should speak to your physician about suspending your medication temporarily. Dentists often recommend a suspension of three to nine months before the procedure and three months afterward.

Some research indicates this won’t worsen your osteoporosis symptoms, especially if you substitute another treatment or fortify your skeletal system with calcium and vitamin D supplements. But taking this temporary measure could help protect your teeth in the long run.
