A scoop of ice cream is one of life's little pleasures. But for one in three Americans, it could be something altogether different—an excruciating pain when cold ice cream meets teeth. This short but painful experience that can happen when dental nerves encounter hot or cold temperatures is called tooth sensitivity.
A look at tooth anatomy will help explain why. Teeth are mainly composed of outer enamel, a layer of nerves and blood vessels within the tooth called the pulp, and dentin, a porous layer in between. The pulp nerves pick up temperature and pressure sensations from outside the teeth through a network of tiny passageways (tubules) in the dentin. Enamel muffles these sensations before traveling the tubules, which prevents overstimulation of the nerves.
This careful balance can be disrupted, however, if the enamel becomes eroded by acid from foods or beverages, or as a byproduct of bacteria. This exposes the underlying dentin to the full brunt of outward sensations, which can then impact the nerves and cause them to overreact.
This hyper-sensitivity can also occur around the tooth roots, but for a different reason. Because the gums primarily protect this area rather than enamel, the roots can become hyper-sensitive if they lose gum coverage, a condition known as gum recession caused mainly by gum disease or over-aggressive hygiene.
Besides using dental products that block nerve sensation, reducing sensitivity largely depends on addressing the underlying cause. If gum disease, the focus is on removing plaque, a bacterial film on dental surfaces that causes and sustains the disease. Stopping an infection allows the gums to heal and hopefully regain their original teeth coverage. More advanced cases, though, may require grafting surgery to foster gum regeneration.
If the cause is enamel erosion or other results of decay or trauma, we can utilize a number of treatments depending on the extent of tooth damage including cavity filling, root canal therapy or crowning. As a last resort, we may need to remove a tooth that's beyond reasonable repair.
If you've begun to experience sensitive teeth, it's important that you see us as soon as possible. The earlier we can diagnose the cause, the less invasive we can be with treatments to ease or even stop this most unpleasant experience.

If you live an average lifespan, you'll spend more than 200,000 hours in blissful slumber. It's not a waste, though: You absolutely need this much sleep to maintain optimum physical and mental health. That's why the National Sleep Foundation recognizes each March as Sleep Awareness Month to highlight the obstacles to a good night's sleep. One such obstacle is obstructive sleep apnea (OSA)—and if you have it, we may be able to help you reduce the harm it may be causing you.
OSA is the blockage of the airway during sleep, usually when the tongue relaxes against the back of the throat. As the oxygen level falls, the brain arouses the sleeper to restore airflow. This only takes a few seconds before the person slips back into sleep, but it can occur several times an hour.
As this scenario repeats itself night after night, the person becomes deprived of the deeper stages of sleep they need to stay healthy. The long-term effect can even be life-threatening: Besides chronic fatigue and “brain fog,” there's also an increased risk of high blood pressure, disease or other serious health conditions.
But there are ways to reduce chronic OSA, the most common being a therapy known as continuous positive airway pressure (CPAP). A CPAP machine, prescribed by a medical doctor, consists of a small pump that streams pressurized air into the mouth through a hose and facemask; the increased air pressure in the mouth helps keep the airway open. It's a proven method, but not always a favorite with some patients who find it uncomfortable and restrictive to wear every night.
If you're in that camp regarding CPAP therapy, an alternative may be possible: oral appliance therapy (OAT), which dentists can provide. Worn in the mouth during sleep, this custom-fitted mouthguard-like appliance repositions the tongue so that it doesn't block the airway. There is a variety of mechanisms, but most involve a hinge that positions the lower jaw forward, which in turn pulls the tongue away from the back of the throat.
These less invasive OAT devices may be an alternative to CPAP therapy for people who have mild to moderate OSA and find CPAP machines difficult to use. If you've been diagnosed with OSA and CPAP therapy hasn't been a good fit for you, speak with us about an OAT device. It could help you overcome this common disorder and get the deep sleep you need for a healthy mind and body.

“Personalize Your Plate” is the theme for this year's National Nutrition Month in March, sponsored by the Academy of Nutrition and Dietetics. It means there isn't a single diet for all of us: We're each unique with differing body types and tastes, and our diets need to be unique as well. Still, though, you'll want to be sure to include basic nutrients that are generally good for all of us—including for our teeth.
As you “personalize” your daily diet, be sure it includes dental-friendly vitamins and minerals. Here are some of the more important ones that contribute to strong and healthy teeth, and the kinds of foods in which you'll find them.
Vitamin D. This vitamin is a key element for growing and maintaining healthy teeth and bone, mainly by helping the body absorb calcium. You'll find vitamin D in milk, eggs or fatty fish—and you'll also gain a little strolling outdoors in the sunshine!
Vitamin E. As an antioxidant, vitamin E helps the body fight free radical molecules that contribute to cancer development, including oral cancer. You'll find vitamin E naturally in seeds and nuts (and derivative cooking oils), wheat germ and whole grains.
Calcium. When included with vitamin D and phosphorus, calcium is an important “construction material” for building strong teeth and bones. You'll find calcium in dairy products like milk and cheese as well as greens, legumes and tofu.
Phosphorus. Eighty-five percent of the body's phosphorus, a companion mineral to calcium, is found in teeth and bones, where it helps to keep them strong and healthy. You'll find this important mineral in meats, milk and eggs.
Magnesium. This mineral helps mineralize teeth and bones, giving them strength and protection against disease. You can get magnesium by eating nuts, legumes, whole grains, dark leafy greens, seafood and—if you limit the added sugar content—chocolate.
Fluoride. Most people are familiar with fluoride added to drinking water or toothpaste to strengthen tooth enamel against tooth decay, but the mineral also occurs naturally in some foods. You can obtain low amounts of fluoride in seafood and black or green tea.
One last thing! While we're promoting foods that you should eat for healthier teeth, there's also one you'll want to cut back on: processed sugar. This carbohydrate is a major factor in oral bacterial growth that causes tooth decay and gum disease. So, eating foods low in sugar and high in these key vitamins and minerals will help ensure your teeth stay healthy.

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.

Life has changed dramatically over the centuries. But although our ancient forebears wouldn't recognize much of our modern world, they would be well acquainted with one particular oral habit that still persists. There's some evidence from archeological dental examinations that our ancestors also clenched or ground their teeth.
This habit of involuntarily gnashing, clenching or grinding the teeth together is most prevalent among children, although not considered a major problem at these younger ages. But it can continue into adulthood, as it does for one in ten people, and lead to an array of problems from worn teeth to jaw joint pain.
As to why adult teeth grinding occurs, researchers have proposed a number of possibilities. Some believe it may be related to the arousal response that occurs when a person passes through various stages of sleep. It also appears that certain psychoactive drugs can trigger it. But at the top of the cause list, teeth grinding is believed to be a physical outlet for stress.
Because of the possibility of multiple causes, there is no one method for treatment—instead, it's better to tailor treatments to the individual. Universally, though, patients who use drugs, alcohol or tobacco, all of which are considered contributing factors, may reduce grinding episodes by restricting their use of these substances.
It's also possible to reduce the incidence of teeth grinding through better stress management. People can learn and use individual relaxation techniques like meditation, mindfulness or biofeedback. For sleep-related teeth grinding it may also be helpful to forgo use of electronic devices before bedtime for a better night's sleep.
Dental treatments like an occlusal guard worn mainly during sleep can minimize the effects of nocturnal teeth grinding. This custom-made appliance prevents teeth from coming fully into contact with each other, thus lowering the intensity of the biting forces generated and preventing cumulative damage to teeth and dental work.
If you have symptoms like sore teeth and jaws, reports from your family hearing you grind your teeth, or catching yourself during the day clenching your teeth, make an appointment for a full examination. From there, we'll help you find the right combination of solutions to keep this old habit from complicating your oral health.
