For decades, traditional braces were the only orthodontic choice for moving misaligned teeth. Although they’re quite effective, they can cause discomfort and, for teens especially, embarrassment due to their noticeable metallic appearance.
In recent years, though, technology has produced an alternative to braces that’s proven effective for many types of patients. Besides being less cumbersome and disruptive to everyday life than braces, clear aligners have another advantage that appeals to teens — they’re much less visible.
Introduced in the late 1990s, clear aligners are a system of individual trays made of nearly invisible polyurethane plastic worn over the upper teeth. The trays are computer-generated based on the patient’s individual mouth structure captured in photographs and x-rays. Each tray in the sequence is incrementally smaller in size; the patient begins wearing the first aligner in the series for about two weeks, 20 to 22 hours a day. They then switch to the next tray in the series for about the same amount of time, and continue in this fashion until they’ve worn each aligner in the series.
Besides their improvement in appearance, aligners also have another advantage: unlike traditional braces, aligners can be removed from the mouth for eating or on a limited basis for rare important social occasions. Brushing and flossing are also much easier with aligners, which don’t pose the same access problems as traditional braces.
Clear aligners were once only effective with select types of orthodontic patients, which didn’t always include teens. Over the last decade, however, significant changes to design and additional implements have widened their application to more patients, especially teens. For example, we can now add tiny “power ridges” to the aligner design that give greater precision over desired tooth movement to create a more controlled and efficient force on the teeth. More recent aligners are also being produced with a thinner, more comfortable material.
A thorough orthodontic exam will tell whether your teen is a good candidate for clear aligners. If so, they’ll benefit from a more comfortable and less embarrassing experience while gaining a new smile for life.

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.
