Dental implants are by far the best way to replace missing teeth. But they do more than improve your smile: they can restore your ability to eat, chew and talk properly, especially if the teeth replaced are in the back of your mouth. What’s more, they can improve the entire look of your face by restoring facial height and cheek support lost because of the missing teeth.
There is, however, one obstacle to overcome before receiving dental implants — a lack of sufficient bone at the implant site. Bone loss usually occurs when teeth have been missing for some time. This is because when we chew the forces generated by the teeth stimulate continual bone growth to make up for older bone that has dissolved (resorbed). This stimulation doesn’t occur after teeth are lost, which slows the rate of bone growth. Over time the amount of healthy bone diminishes.
Without enough bone for support, implants can’t be placed properly. Fortunately, some of the bone can be regenerated through techniques that place bone grafting material at the site to stimulate and serve as a scaffold for new bone.Â The new bone will eventually replace the graft.
For missing upper back teeth with bone loss, we can take advantage of facial anatomy to grow the bone needed for implants. This area of the face is where the maxillary sinuses, air spaces lined with a tissue membrane, are located on either side just above the upper jaw. After determining their exact size and location through detailed x-ray imaging, we can surgically access the area inside the mouth just above the missing teeth.
The sinus cavity is an area where bone growth can occur by placing a bone graft between the floor of the sinus and the sinus membrane. Sometimes bone growth enhancers are used to stimulate and speed up regeneration. The procedure can usually be performed with local anesthesia (much like a routine tooth filling), with only mild discomfort afterward for a few days managed by an anti-inflammatory drug like ibuprofen and a decongestant for sinus swelling.
After six to seven months, we re-evaluate the area to see if sufficient bone has returned for implant surgery. If so, you will be well on your way to achieving a new look and better function through dental implants.

If your sleeping partner snores, it could be more than an annoyance: it could be a sign of sleep apnea. This occurs when air flow into the lungs becomes obstructed in the throat for a few seconds during sleep. The obstruction can take many forms, but a common one arises from the tongue relaxing against the back of the throat, producing snoring sounds as air attempts to pass through this restricted area.
Sleep apnea can cause severe problems: lower daily energy levels and mood from poor sleep; lower oxygen saturation that could affect brain function; and increased risk for cardiovascular disease. So, if you’re awakened by your partner’s snoring (or they’re complaining about yours!), it’s important to have it checked and treated.
This begins with a visit to us for a complete oral examination. Like many dentists, we’re well trained in the anatomy and structures of the mouth, as well as the causes and treatment of sleep apnea. We’ll examine your mouth, take into account any possible symptoms you’re experiencing and, if your suspicions are correct, refer you to a sleep physician to diagnose if you have sleep apnea.
Treatment will depend on its cause and severity. An oral appliance worn during sleep is the recommended first treatment for mild to moderate sleep apnea that involves the tongue as an obstruction. We develop a custom appliance that helps move your tongue away from the back of the throat, reducing both apnea and snoring sounds. For more advanced sleep apnea you could benefit from a Continuous Positive Airway Pressure (CPAP) machine. This device generates continuous air pressure through a mask worn while sleeping that helps keep the airway open.
Of course, there are other causes for obstruction, some of which may require surgical intervention to relieve the problem. Abnormally large tonsils, adenoids or excessive soft tissue can all restrict air flow. Surgically removing or altering these structures could help reduce airway restriction.
Whatever type or degree of sleep apnea you or your partner may have, there are solutions. The right treatment will not only improve overall health, it will help both of you get a better night’s sleep.

We’ve all had physical ailments that were more irritating than serious. The problem of skin cracking at the corners of the mouth fits into that category.
Both dentists and dermatologists encounter this condition often and have a name for it: perleche, derived from the French word lecher, meaning “to lick.” The term arises from patients’ tendency to excessively lick the broken skin to soothe the itching or burning.
Perleche most often arises from certain mouth conditions, although systemic problems like anemia or diabetes may also cause it. Children or younger adults, especially those with orthodontic braces or a tendency to drool as they sleep, often develop perleche; older adults with wrinkling around the mouth are also susceptible. Mouth dryness caused by reduced saliva flow may also irritate the skin and cause discomfort.
As the skin becomes irritated, the person may begin to lick the corners of the mouth to soothe them. This sets up conditions for an infection, most often caused by yeast known as candida albicans. The infection may become more acute and begin to affect the entire inside of the mouth or throat.
If you’ve developed perleche, our primary treatment goal is to reduce any infection with the aid of oral or topical antifungal drugs. One drug, Nystatin, is often taken as a lozenge that dissolves in the mouth and works its way from there through the rest of the body. You can also apply antifungal ointments several times a day to the corners of the mouth, often in combination with steroid ointments that reduce redness and swelling. You can also apply antifungal zinc oxide paste to the cracked skin, which also serves as a barrier between the skin and outer contaminants.
To reduce the chance of future outbreaks, we may recommend you rinse with Chlorhexidine, as well as replace missing teeth or refit loose dentures — these too are contributing factors to erupting yeast infections. You might also need to undergo dermatologic treatment for wrinkles if they’ve proven to be a factor in developing perleche.
Although not a major problem, perleche can be exceedingly uncomfortable and embarrassing. Thanks to a number of treatment options, you don’t have to put up with that discomfort for long.
