Osteoporosis is a serious bone weakening disease in older adults that can turn a minor fall into a major bone fracture. But the condition could also impact dental treatment—triggered ironically by the drugs used to treat osteoporosis rather than the disease itself.
From the Latin for “porous bone,” osteoporosis causes bone to gradually lose mineral structure. Over time the naturally-occurring spaces between mineralized portions of the bone enlarge, leaving it weaker as a result.
Although there's no definitive cure for osteoporosis, a number of drugs developed over the last couple of decades can inhibit its progress. Most fall into two major categories, bisphosphonates and RANKL inhibitors.
These drugs work by inhibiting the normal growth cycle of bone. Living bone constantly changes as cells called osteoblasts produce new bone. A different type, osteoclasts, clear away older bone to make room for these newer cells. The drugs selectively destroy osteoclasts so that the older bone, which would have been removed by them, remains for a longer period of time.
Retaining older cells longer initially slows the disease process. But there is a downside: in time, this older bone kept in place continues to weaken and lose vitality. In rare instances it may eventually become detached from its blood supply and die, resulting in what is known as osteonecrosis.
Osteonecrosis mostly affects two particular bones in the body: the femur (the long bone in the upper leg) and the jawbone. In regard to the latter, even the stress of chewing could cause osteonecrosis in someone being treated for osteoporosis. It can also occur after tooth extractions or similar invasive procedures.
If you're taking a bisphosphonate or RANKL inhibitor, you'll want to inform your dentist so that the necessary precautions can be taken before undergoing dental work more invasive than routine cleanings or getting a filling or crown. If you need major dental work, your dentist or you will also need to speak with your physician about stopping the drug for a few months before and after a dental procedure to minimize the risk of osteonecrosis.
Fortunately, the risk for dental problems while undergoing treatment for osteoporosis is fairly low. Still, you'll want to be as prepared as possible so that the management of your osteoporosis doesn't harm your dental health.

It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.
This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.
Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.
Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.
Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.
In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.
More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.

Breastfeeding is nature's way of providing complete nourishment to a newborn in their first years of life. It can also have a positive impact on their emerging immune system, as well as provide emotional support and stability. But although nursing comes naturally to an infant, there are circumstances that can make it more difficult.
One example is an abnormality that occurs in one in ten babies known as a tongue tie. A tongue tie involves a small band of tissue called a frenum, which connects the underside of the tongue with the floor of the mouth. The frenum, as well as another connecting the inside of the upper lip with the gums, is a normal part of oral anatomy that helps control movement.
But if the frenum is too short, thick or taut, it could restrict the movement of the tongue or lip. This can interfere with the baby acquiring a good seal on the breast nipple that allows them to draw out milk. Instead, the baby may try to chew on the nipple rather than suck on it, leading to an unpleasant experience for both baby and mother.
But this problem can be solved with a minor surgical procedure called a frenotomy (also frenectomy or frenuplasty). It can be a performed in a dentist's office with just a mild numbing agent applied topically to the mouth area (or injected, in rare cases of a thicker frenum) to deaden it. After a few minutes, the baby's tongue is extended to expose the frenum, which is then snipped with scissors or by laser.
There's very little post-op care required (and virtually none if performed with a laser). But there may be a need for a child to “re-learn” how to breastfeed since the abnormal frenum may have caused them to use their oral muscles in a different way to compensate. A lactation expert may be helpful in rehabilitating the baby's muscles to nurse properly.
A restrictive frenum isn't necessarily a dire situation for an infant—they can continue to feed with a bottle filled with formula or pumped breastmilk. But employing this minor procedure can enable them to gain the other benefits associated with breastfeeding.
