Daily fatigue or complaints of your snoring from family have led you to see your doctor about the problem. After an exam and a test session in a sleep lab, your problem now has a name — obstructive sleep apnea.
This common sleep-related breathing disorder (SRBD) occurs when the soft tissues in the back of the throat over-relax during sleep. The relaxed tissues obstruct air flow to the trachea (windpipe) and cause “apnea,” where you cease to breathe. The lack of oxygen causes you to wake, even for a micro-second, to begin breathing again. This may occur multiple times throughout the night, diminishing the quality of your sleep and leading not only to drowsiness and daily fatigue but also contribute to cardiovascular disease or other systemic conditions.
The most effective treatment for sleep apnea is the use of a Continuous Positive Airway Pressure (CPAP) machine while you sleep. The machine delivers pressurized air to a face mask you wear while you sleep; the additional pressure keeps the airway open. However, a CPAP machine does have a few disadvantages, including discomfort while attached to the machine, nasal congestion and dryness, or claustrophobia. These effects can be so pronounced for some patients, they’re unable to adjust themselves to the machine.
If you have mild to moderate sleep apnea, there may be an alternative — a custom-fitted oral appliance we manufacture for you to wear in your mouth while you sleep. The appliance pulls the lower jaw forward resulting in a wider opening of the airway. In addition to being less cumbersome than a CPAP mask, an oral appliance is easier to wear, compact in size for easy travel and doesn’t require electricity.
While an oral appliance is an effective alternative to a CPAP machine for many patients, it does have a few disadvantages including problems with saliva flow (too much or too little), muscle or teeth soreness and minor tooth or jaw movement. Still, an oral appliance might be the right solution to relieve your sleep apnea over the long-term.

Whether performed in a dental office or using a home kit, teeth whitening applications are quite effective for bleaching exterior (extrinsic) stains on enamel surfaces. But what if your discoloration comes from inside the tooth? In this case, extrinsic teeth whitening won’t work — you’ll need to undergo an “internal bleaching” method, which can only be performed in a dentist's office.
There are a number of causes for “intrinsic” staining, including too much fluoride exposure or tetracycline use during childhood. One of the more common causes, though, occurs from root canal treatments used to remove the remnants of the pulp tissue inside a tooth’s pulp chamber and root canals. Certain cements used during the procedure to help seal in the filling material and leftover blood pigments can cause the tooth to darken over time.
To alleviate this discoloration, we use a bleaching agent, usually sodium perborate mixed with a diluted solution of hydrogen peroxide to achieve a safe, accelerated color change. After determining that the root canal filling is still intact and the bone is healthy, we create a small cavity in the back of the tooth to access the pulp chamber. The chamber is cleaned of any debris or stained material and then thoroughly irrigated. The original root canal filling is then sealed off to prevent leakage from the bleaching agent.
We then place the bleaching agent in the cleaned-out space with a cotton pellet and seal it in with a temporary adhesive. This step is repeated for several days until we achieve the desired shade of white. Once that occurs we then seal the dentin with a more permanent filling and then restore the cavity we created with a composite resin bonded to the enamel and dentin.
If we’re successful in achieving the desired color, intrinsic whitening could help you avoid more costly options like veneers or crowns for an otherwise healthy and attractive tooth. The end result would be the same — a beautiful smile without those unsightly stains.

Good nutrition is vital for maintaining health and preventing disease, especially for your mouth. A diet rich in whole foods — fresh fruits and vegetables, protein and dairy products — and low in sugar will not only promote strong teeth and gums, but lessen your chances of developing tooth decay or periodontal (gum) disease.
Diet is also a prominent factor in reducing the risk for another serious mouth disease — oral cancer. While oral cancer makes up only 3% of total cancer cases reported annually, the five-year survival rate is a sobering 50%, much lower than for other types of common cancers. While genetics plays a role in your susceptibility to oral cancer, lifestyle choices and practices present the greater risk factors for the disease.
Of these lifestyle factors, refraining from tobacco products, moderating your alcohol consumption and avoiding risky sexual behavior are of primary importance in reducing your cancer risk. With that said, you should also take into account the foods that are part of your daily diet — both what you should and shouldn’t eat. As an example of the latter, some foods contain a class of chemicals known as nitrosamines that are carcinogenic (cancer-causing). One such chemical, nitrite, is used as a preservative in meats like bacon or ham, and may also be found in beer, and seafood products.
On the positive side, your diet should be rich in foods that supply antioxidants, substances that protect the body’s cells from damaging, unstable molecules known as free radicals. The best sources for antioxidants (more so than dietary supplements) are plant foods rich in fiber and vitamins C and E. Eating more of these may also reduce your intake of nitrates, animal fat and saturated fat.
Adopting a moderate, nutritious diet, along with exercise, can have a huge positive impact on your general health and quality of life. Along with other lifestyle changes, better dietary choices can also help ensure a healthy mouth and reduce your risk of oral cancer.

We always look forward to seeing our patients, but not all of you look forward to seeing us! If you’re one of them, don’t worry — we don’t take it personally. Dental anxiety prevents many people from seeking the care they require to restore or maintain a healthy smile.
But if dental problems are allowed to progress, they can affect not only the beauty of your smile and health of your mouth, but your overall wellness, too. Infection can travel from the mouth to other areas of the body, and dental disease exacerbates chronic health conditions like heart disease or diabetes.
Fear should never be an obstacle (in the immortal words of President Franklin Roosevelt, “…the only thing we have to fear is fear itself…”). And fortunately there are some safe options for those of us who can’t get past our anxiety when it comes to dental care:
Oral Sedation. A sedative medication can be prescribed that you take by mouth approximately an hour before your dental visit to minimize anxiety and promote relaxation.
Intravenous (IV; “intra” – inside, “venous” – vein) Sedation. If oral sedation isn’t entirely effective in facilitating treatment, then a medication combining a sedative for relaxation and a pain-blocking anesthetic can be delivered through or small needle or catheter that is gently inserted into a vein. This is referred to as “conscious sedation” because you are in a semi-awake state during which you are able to respond to verbal direction. It takes effect quickly, and you can come out of it quickly. However, you may not remember much about your procedure. It is very different from general anesthesia during which you are completely unconscious.
Dentists who offer IV sedation receive extensive training after which we must pass an exam and apply for a special permit that we maintain through continuing education. We carefully screen patients for eligibility and monitor you throughout so you can rest easy before, during, and after your procedure.

There are a number of teeth whitening options to put the brightness back into your smile — from professional dentist office applications to over-the-counter products for home use. But before you decide on an option, you should first consider whether whitening is right for you and to what extent.
Here are 3 questions to ask yourself — and us — before undergoing a whitening treatment.
Do I have any dental problems that make whitening problematic? The underlying cause of the staining may stem from decay, root canal problems or other dental issues; in these cases the underlying cause needs to be treated first, because whitening would only mask the actual problem. You also may not want to whiten your teeth for aesthetic reasons: people with certain features like short teeth or gummy smiles may find these features become more prominent after teeth whitening. It might be more advisable in these cases to consider other cosmetic options first.
How much whitening do I really need to improve my smile? One of the biggest myths about teeth whitening is the brighter the shade the more attractive the smile. A truly attractive tooth color, however, is more nuanced, and every person’s ideal color is different. The most attractive and natural color is one that matches the whites of your eyes.
What effect will whitening have on existing dental work I already have? In most cases, none — and that could be a problem. Composite resins or ceramic dental material have their color “baked in” and bleaching chemicals used in whitening have no effect on them. The concern then is whether whitening nearby natural teeth may produce a color mismatch between them and the dental restorations, resulting in an unattractive appearance.
Before you decide on teeth whitening, visit us first for a complete exam and consultation. We’ll discuss whether whitening is a good option for you, or whether there are other issues we should address first. We can also advise you on products and techniques, and how to get the most from your whitening experience.
