One in 700 babies are born each year with a cleft lip, a cleft palate or both. Besides its devastating emotional and social impact, this common birth defect can also jeopardize a child's long-term health. Fortunately, incredible progress has occurred in the last half century repairing cleft defects. Today's children with these birth defects often enter adulthood with a normal appearance and better overall health.
A cleft is a gap in the mouth or face that typically forms during early pregnancy. It often affects the upper lip, the soft and hard palates, the nose or (rarely) the cheek and eye areas. Clefts can form in one or more structures, on one side of the face or on both. Why they form isn't fully understood, but they seem connected to a mother's vitamin deficiencies or to mother-fetus exposure to toxic substances or infections.
Before the 1950s there was little that could be done to repair clefts. That changed with a monumental discovery by Dr. Ralph Millard, a U.S. Navy surgeon stationed in Korea: Reviewing cleft photos, Dr. Millard realized the “missing” tissue wasn't missing—only misplaced. He developed the first technique to utilize this misplaced tissue to repair the cleft.
Today, skilled surgical teams have improved on Dr. Millard's efforts to not only repair the clefts but also restore balance and symmetry to the face. These teams are composed of various oral and dental specialties, including general dentists who care for the patient's teeth and prevent disease during the long repair process.
Cleft repairs are usually done in stages, beginning with initial lip repair around 3-6 months of age and, if necessary, palate repair around 6-12 months. Depending on the nature and degree of the cleft, subsequent surgeries might be needed throughout childhood to “polish” the original repairs, as well as cosmetic dental work like implants, crowns or bridgework.
In addition to the surgical team's skill and artistry, cleft repair also requires courage, strength and perseverance from patients and their parents, and support from extended family and friends. The end result, though, can be truly amazing and well worth the challenging road to get there.

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.

Breathing: You hardly notice it unless you're consciously focused on it—or something's stopping it!
So, take a few seconds and pay attention to your breathing. Then ask yourself this question—are you breathing through your nose, or through your mouth? Unless we're exerting ourselves or have a nasal obstruction, we normally breathe through the nose. This is as nature intended it: The nasal passages act as a filter to remove allergens and other fine particles.
Some people, though, tend to breathe primarily through their mouths even when they're at rest or asleep. And for children, not only do they lose out on the filtering benefit of breathing through the nose, mouth breathing could affect their dental development.
People tend to breathe through their mouths if it's become uncomfortable to breathe through their noses, often because of swollen tonsils or adenoids pressing against the nasal cavity or chronic sinus congestion. Children born with a small band of tissue called a tongue or lip tie can also have difficulty closing the lips or keeping the tongue on the roof of the mouth, both of which encourage mouth breathing.
Chronic mouth breathing can also disrupt children's jaw development. The tongue normally rests against the roof of the mouth while breathing through the nose, which allows it to serve as a mold for the growing upper jaw and teeth to form around. Because the tongue can't be in this position during mouth breathing, it can disrupt normal jaw development and lead to a poor bite.
If you suspect your child chronically breathes through his or her mouth, your dentist may refer you to an ear, nose and throat (ENT) specialist to check for obstructions. In some cases, surgical procedures to remove the tonsils or adenoids may be necessary.
If there already appears to be problems brewing with the bite, your child may need orthodontic treatment. One example would be a palatal expander, a device that fits below the palate to put pressure on the upper jaw to grow outwardly if it appears to be developing too narrowly.
The main focus, though, is to treat or remove whatever may be causing this tendency to breathe through the mouth. Doing so will help improve a child's ongoing dental development.
