Osteoporosis is a major health condition affecting millions of people, mostly women over 50. The disease weakens bone strength to the point that a minor fall or even coughing can result in broken bones. And, in an effort to treat it, some patients might find themselves at higher risk of complications during invasive dental procedures.
Over the years a number of drugs have been used to slow the disease’s progression and help the bone resist fracturing. Two of the most common kinds are bisphosphonates (Fosamax) and RANKL inhibitors (Prolia). They work by eliminating certain bone cells called osteoclasts, which normally break down and eliminate older bone cells to make way for newer cells created by osteoblasts.
By reducing the osteoclast cells, older bone cells live longer, which can reduce the weakening of the bone short-term. But these older cells, which normally wouldn’t survive as long, tend to become brittle and fragile after a few years of taking these drugs.
This may even cause the bone itself to begin dying, a relatively rare condition called osteonecrosis. Besides the femur in the leg, the bone most susceptible to osteonecrosis is the jawbone. This could create complications during oral procedures like jaw surgery or tooth extractions.
For this reason, doctors recommend reevaluating the need for these types of medications after 3-5 years. Dentists further recommend, in conjunction with the physician treating osteoporosis, that a patient take a “drug holiday” from either of these two medications for several months before and after any planned oral surgery or invasive dental procedure.
If you have osteoporosis, you may also want to consider alternatives to bisphosphonates and RANKL inhibitors. New drugs like raloxifene (which may also decrease the risk of breast cancer) and teriparatide work differently than the two more common drugs and may avoid their side effects. Taking supplements of Vitamin D and calcium may also improve bone health. If your physician still recommends bisphosphonates, you might discuss newer versions of the drugs that pose less risk of osteonecrosis.
Managing osteoporosis is often a balancing act between alleviating symptoms of the disease and protecting other aspects of your health. Finding that balance may help you avoid future problems, especially to your dental health.

Dental amalgam—also known as “silver fillings”—has been used for nearly a hundred years to treat cavities. There are several reasons why this mixture of metals has been the go-to material among dentists: Malleable when first applied, dental amalgam sets up into a durable dental filling that can take years of biting forces. What’s more, it’s stable and compatible with living tissue.
But there’s been growing concern in recent years about the safety of dental amalgam, with even some wondering if they should have existing fillings replaced. The reason: liquid mercury.
Mercury makes up a good portion of dental amalgam’s base mixture, to which other metals like silver, tin or copper are added to it in powder form. This forms a putty that can be easily worked into a prepared cavity. And despite the heightened awareness of the metal’s toxicity to humans, it’s still used in dental amalgam.
The reason why is that there are various forms of mercury and not all are toxic. The form making headlines is known as methylmercury, a compound created when mercury from the environment fuses with organic molecules. The compound builds up in the living tissues of animals, particularly large ocean fish, which have accumulated high concentrations passed up through their food chain.
That’s not what’s used in dental amalgam. Dentists instead use a non-toxic, elemental form of mercury that when set up becomes locked within the amalgam and cannot leach out. Based on various studies, treating cavities with it poses no health risks to humans.
This also means there’s no medical reason for having an existing silver fillings removed. Doing so, though, could cause more harm than good because it could further weaken the remaining tooth structure.
The most viable reason for not getting a dental amalgam filling is cosmetic: The metallic appearance of amalgam could detract from your smile. There are newer, more life-like filling options available. Your dentist, though, may still recommend dental amalgam for its strength and compatibility, especially for back teeth. It’s entirely safe to accept this recommendation.
Orthodontic braces are a familiar sight, especially among tweens and teens: metal brackets and wires attached to the front of the teeth for all to see. Now imagine the opposite: much the same hardware, but now positioned out of sight on the back of the teeth.
It's not your imagination: It's the latest development in orthodontic technology called lingual braces. Developed simultaneously by two orthodontists in Japan and Beverly Hills, these appliances are placed on the tongue or “lingual” side of the teeth rather than the traditional labial or “lip-side.”
Generally, lingual braces can correct any bite problem labial braces can. The difference lies in how each method does its job: Traditional braces exert pressure or “push” against the teeth, while lingual braces “pull” the teeth into better alignment.
So, why choose lingual over labial? For one, they're “invisible” to others: all the hardware is on the backside of the teeth, out of sight. They're also not as readily exposed to blunt force facial trauma, which can damage traditional braces (a driving impetus for the Japanese doctor to develop them for his martial arts patients, and his American counterpart for a law enforcement patient working in a rough area).
Patients may also prefer lingual braces over removable clear aligners, another popular tooth-movement option. Fixed lingual braces achieve the same quality of “invisibility” as removable aligners, but without the inconvenience of removing them as patients must with aligners for eating, snacking or cleaning.
They can, however, be costly, running 15-35% more than labial braces. Patients may also have difficulty adjusting to them because they can affect speech and tongue comfort. However, any discomfort and initial regret with choosing lingual braces tends to fade as most patients grow more accustomed to them after a week or so.
There's one other “perk” to lingual braces—unlike patients with traditional braces who have to wait for their removal to see the finished bite correction, patients with lingual braces get an unobstructed view of their progress all during wear. That can definitely boost morale during the long treatment period!
Lingual braces haven't been around long, so not every orthodontist offers them. But the list is growing, and there soon may be a provider near you for this new teeth-straightening alternative.
