Accidents can happen to your mouth, especially if you have an active lifestyle. For example, a sudden blow to the jaw while playing sports or exercising could result in a chipped tooth. And, while the internal tooth structure may be fine, the effect on your appearance can be disheartening.
Fortunately, we have techniques and materials to restore your smile after an injury. Bonding with composite resin is one such procedure: it’s ideal for mild to moderate chipping, especially in highly visible front teeth.
Composite resin is a dental material made of various substances mixed to match the color and texture of natural teeth. The composite is usually made of inorganic glass filler blended with a plastic-based matrix and joined together with a chemical “coupling” agent. The ratio of filler to matrix will depend on the type of tooth and damage — for example, back teeth, which encounter higher biting forces, require a composite with more filler for added strength.
To begin the procedure, we first prepare the damaged tooth by applying microscopic etchings (often with a chemical solution) that create tiny depressions or “undercuts”: these help create a seamless bond between the composite and the natural tooth. We then apply the composite in layers with a bonding agent, building up layer upon layer until we’ve achieved the desired shape for the tooth involved.
Bonding with composite resins doesn’t require much tooth preparation, can be placed quickly and is relatively inexpensive. Because of the wide spectrum of color possibilities, composite resins are superior to traditional amalgam (metal) restorations in creating a more life-like appearance. Its application, however, can be limited by the amount of tooth structure needing to be replaced: because it isn’t as strong as the tooth structure it replaces, the more tooth structure the bonded composite resin attempts to replace the less likely it can stand up over time to normal bite forces.
Still, composite resins are ideal for mild to moderate damage or disfigurement. If you’ve suffered such an injury, be sure to visit us to see if bonding with life-like composites is the right solution for restoring your smile.

The food we eat not only provides us energy, but it also supplies nutrients to help the body remain healthy. The most important of these nutrients are minerals and tiny organic compounds called vitamins.
While all of the thirteen known vitamins and eleven minerals play a role in overall health, a few are especially important for your mouth. For example, vitamins D and K and the minerals calcium and phosphorus are essential for strong teeth. Another mineral, fluoride, helps fortify enamel, which can deter tooth decay.
Other vitamins and minerals serve as antioxidants, protecting us against molecules called free radicals that can damage cellular DNA and increasing our risk of cancer (including oral). Vitamins C and E and the mineral selenium fall into this category, as well as zinc for DNA repair.
We acquire these nutrients primarily in the foods we eat. But for certain people like older adults or pregnant or nursing women a healthy diet may not be enough. Any person who can't get enough of a particular vitamin or mineral should take a supplement to round out their nutritional needs.
If you don't have a condition that results in a nutrient deficiency, you may not see that much benefit from taking a supplement. In fact, taking too much of a dietary supplement could harm your health. For example, some studies have shown ingesting too much supplemental Vitamin E could increase the risk of heart failure or gastrointestinal cancer. And some dietary supplements can interact poorly with drugs like blood thinners or ibuprofen.
The best way to get the vitamins and minerals your body — and mouth — needs is to eat a healthy diet. Dairy products like fortified milk are a good way to get vitamin D, as well as calcium and phosphorus. Fruits and vegetables are a good source of Vitamin C. And while you can take in fluoride from toothpaste or other oral hygiene products, you'll also find it in seafood and tea.
While good oral hygiene and regular dental visits are necessary for dental health, your diet can also make a difference. Be sure you're getting all the nutrients your teeth and gums need.

We all know how much better we feel after a good night’s sleep: refreshed, energized and ready to handle — even excel at — our day-to-day responsibilities. Yet millions of people, young and old, are robbed of a good night’s rest by sleep-related breathing disorders such as sleep apnea, in which the soft tissues in the back of the throat block the airway during sleep. This temporarily disrupts airflow, causing numerous “micro-arousals” (sleep interruptions) that we may not even be aware of. A lack of sleep can make us drowsy, irritable and unfocused. In children, these typical symptoms of sleep apnea can lead to mistaken diagnoses of Attention Deficit Hyperactivity Disorder (ADHD).
The relationship between sleep apnea and behavioral problems has been highlighted in several recent scientific journal articles, including a major study published several years ago in Pediatrics, the official journal of the American Academy of Pediatrics. The lead author, Dr. Karen Bonuck, said at the time: “We found that children with sleep-disordered breathing were from 40 to 100 percent more likely to develop neurobehavioral problems by age 7, compared with children without breathing problems. The biggest increase was in hyperactivity, but we saw significant increases across [other] behavioral measures.” Therefore, an accurate diagnosis of a child’s behavioral problems — leading to the right treatment — is crucial. While sleep apnea must be diagnosed by a physician, treatment for the condition is often provided by a dentist.
What can be done for children suffering from sleep apnea? The most common treatment is surgical removal of the tonsils or adenoids. This treatment can sometimes be performed by an oral and maxillofacial surgeon, a dentist who has received several years of post-graduate surgical training. There are several other procedures oral surgeons can perform to open the airway, depending on what anatomical structures are blocking it.
Sometimes a child with sleep apnea can benefit from a procedure to expand the palate (roof of the mouth) to enlarge the airway. This is not a surgical treatment but rather an orthodontic one. An orthodontist (a dentist who specializes in moving teeth) will fit the child with a palatal expander, a butterfly-shaped device that gradually separates the two bones that form the upper jaw and roof of the mouth. This is often done to prevent crowding of teeth and other bite problems, but has been shown in some cases to improve airflow.
There is another dental approach used to treat adults and older children, whose jaw growth is complete. It’s called oral appliance therapy, and it involves wearing a custom-made device during sleep that resembles a sports mouthguard or orthodontic retainer. An oral appliance can maintain an opened, unobstructed, upper airway during sleep in various ways, including: repositioning the lower jaw, tongue, soft palate and uvula; stabilizing the lower jaw and tongue; increasing the muscle tone of the tongue.
If your child has been diagnosed with sleep apnea, we can help you find the best treatment approach. For more information, please contact us or schedule an appointment for a consultation.
