Recently, a number of new filling materials that mimic tooth color have come into popular use and, so far, have proven more durable than past versions. Even so, the traditional metal-based dental amalgam remains a viable choice, especially for less visible back teeth and their higher biting forces.
Used for more than a century, dental amalgam is a metal alloy composed of silver, mercury, tin and copper. The mixture is carefully proportioned so that potentially hazardous mercury is kept to a minimum and bonded with the other metals. Amalgam in its initial form is quite pliable so that it can be molded into the tooth structure under repair. Afterward it sets hard to form a durable filling that can withstand the daily force generated when we bite and chew food.
Besides durability, dental amalgam rarely causes an allergic reaction in a patient, and it’s easy for trained dentists to apply. On the downside, however, it can cause temporary temperature sensitivity in the tooth just after filling, and the tooth itself may require some removal of healthy structure to help keep the filling in place. And from an aesthetic point of view, its metallic appearance is considered unattractive especially for front teeth.
The presence of mercury in amalgam has also raised concerns over the years. “Free” mercury — atoms that escape through vapor emitted by the metal — can enter the bloodstream and potentially harm the nervous system. But after extensive study and research, U.S. and international health bodies including the American Dental Association have concluded any free mercury released during chewing is extremely low and well below any harmful levels. These studies have also found no ill effects in either children or adults with dental amalgam fillings.
Deciding on the type of filling material to use — dental amalgam or a newer composite resin, resin ionomer or glass ionomer — depends on a number of factors including the location of the teeth to be filled, the extent of decay and your personal preferences. Taking these into account, we’ll be happy to discuss which type of filling will suit you best for repairing decayed teeth.

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.

While the sport of golf may not look too dangerous from the sidelines, players know it can sometimes lead to mishaps. There are accidents involving golf carts and clubs, painful muscle and back injuries, and even the threat of lightning strikes on the greens. Yet it wasn’t any of these things that caused professional golfer Danielle Kang’s broken tooth on the opening day of the LPGA Singapore tournament.
“I was eating and it broke,” explained Kang. “My dentist told me, I've chipped another one before, and he said, you don't break it at that moment. It's been broken and it just chips off.” Fortunately, the winner of the 2017 Women’s PGA championship got immediate dental treatment, and went right back on the course to play a solid round, shooting 68.
Kang’s unlucky “chip shot” is far from a rare occurrence. In fact, chipped, fractured and broken teeth are among the most common dental injuries. The cause can be crunching too hard on a piece of ice or hard candy, a sudden accident or a blow to the face, or a tooth that’s weakened by decay or repetitive stress from a habit like nail biting. Feeling a broken tooth in your mouth can cause surprise and worry—but luckily, dentists have many ways of restoring the tooth’s appearance and function.
Exactly how a broken tooth is treated depends on how much of its structure is missing, and whether the soft tissue deep inside of it has been compromised. When a fracture exposes the tooth’s soft pulp it can easily become infected, which may lead to serious problems. In this situation, a root canal or extraction will likely be needed. This involves carefully removing the infected pulp tissue and disinfecting and sealing the “canals” (hollow spaces inside the tooth) to prevent further infection. The tooth can then be restored, often with a crown (cap) to replace the entire visible part. A timely root canal procedure can often save a tooth that would otherwise need to be extracted (removed).
For less serious chips, dental veneers may be an option. Made of durable and lifelike porcelain, veneers are translucent shells that go over the front surfaces of teeth. They can cover minor to moderate chips and cracks, and even correct size and spacing irregularities and discoloration. Veneers can be custom-made in a dental laboratory from a model of your teeth, and are cemented to teeth for a long-lasting and natural-looking restoration.
Minor chips can often be remedied via dental bonding. Here, layers of tooth-colored resin are applied to the surfaces being restored. The resin is shaped to fill in the missing structure and hardened by a special light. While not as long-lasting as other restoration methods, bonding is a relatively simple and inexpensive technique that can often be completed in just one office visit.

There are well-known holidays on the calendar this month, but here’s one that might have escaped your notice: “Keep America Beautiful Month,” which is observed throughout April! At this time, people from coast to coast are encouraged to clean and beautify their communities. So why not think of it as an occasion to spiff up your smile? Here are five ways to do exactly that:
Have your teeth professionally cleaned. A routine dental visit, which includes a professional cleaning and exam, is one of the best preventive healthcare values there is. It’s a chance to catch dental problems (including potentially serious ones like oral cancer) before they become more difficult to treat. A dental professional can remove built-up deposits of tartar from your teeth using specialized instruments—something you can’t do at home. Plus, you’ll leave the office with a freshly polished smile that looks and feels great.
Get a professional teeth whitening. Having whiter teeth often makes people look more youthful. And one of the best ways to brighten dull teeth is with professional teeth whitening. You can achieve the fastest, most dramatic results with an in-office treatment—up to ten shades in just one visit! We can also make you a custom take-home kit to achieve similar results over time.
Repair chipped teeth. If you feel self-conscious about a chipped tooth, consider cosmetic bonding. In this relatively inexpensive procedure, which often takes just one office visit, tooth-colored resin material is applied to the chipped area and hardened under a special light. The translucent resin is built up layer by layer, bringing teeth with minor flaws back to a great, natural-looking appearance.
Replace old dental work. Sometimes old dental work can stand out more than we’d like it to. This is especially true of amalgam (silver) fillings—but even white fillings can absorb stain after many years. If you feel old dental work is detracting from your smile, it may be time to replace it with up-to-date dental materials.
Straighten your smile. Did you know that there is no maximum age for successful orthodontic treatment? It’s true: Healthy teeth can be moved at any age. And if you think metal braces wouldn’t fit in with your look or lifestyle, consider one of the less-visible alternatives to traditional orthodontic hardware—such as ceramic braces and clear aligners.
Having the smile you want can make you feel more confident in any month of the year. If you’d like more information on cosmetic dentistry, please contact us or schedule a consultation.

If you’re facing cancer treatment, we wish you the best outcome possible. Treating this disease has advanced tremendously in recent decades, but the available options are still often challenging to endure. It will be your primary focus for the foreseeable future.
As a dental provider we also want you to be aware how the two main treatments, chemotherapy and radiation, could adversely affect your teeth and gums, especially if you’re receiving radiation therapy near the head and neck. The aim of cancer treatment is to attack and destroy cancer cells to prevent their growth. Unfortunately, it can also destroy neighboring healthy cells and lead to harmful consequences in different parts of the body, including the mouth.
Salivary glands, for example, are especially vulnerable to damage during cancer treatment. This could create a situation where the mouth no longer produces adequate saliva flow, leading to a condition called xerostomia or dry mouth. Besides a lot of discomfort, restricted saliva flow can also increase your risk of tooth decay and other dental diseases. This is because saliva is the body’s acid neutralizer (acid can erode tooth enamel) and its first line of defense against microbial infection.
To guard against this, it’s important to support salivary flow as much as possible if you experience dry mouth symptoms during treatment (as well as beyond—it’s possible the damage to these glands could be permanent). Since some medications also contribute to dry mouth, you should speak with your physician about the prescriptions you’re taking: if any have dry mouth side effects ask if there’s an alternative drug without these side effects. You should also drink more water during the day and especially when taking medications. And consider substances like xylitol gum that can help boost saliva flow.
Unfortunately, it may not be possible to fully avoid the effects of these treatments on your teeth and gums. So, be sure you keep up daily brushing and flossing and see your dentist regularly for cleanings and checkups. If necessary, there are a number of restoration options to restore your smile after you’ve completed your treatment.
