After months or even years of radiation or chemotherapy, the words "cancer-free" is music to your ears. Your joy and relief, though, may be tempered by the toll these treatments can take on the rest of your body—including your mouth.
Both of these treatments can destroy healthy tissue along with targeted cancer cells. If the focus has been on the head and neck regions, they could damage the salivary glands to the point that they won't produce adequate saliva flow.
A lack of saliva can have a detrimental effect on your oral health. Saliva buffers and helps lower oral acid levels that soften and erode enamel and increase the likelihood of tooth decay. Saliva also supplies antibodies that fight disease-causing bacteria. Otherwise, bacteria—and the risk for disease—can rapidly grow.
If these or other scenarios occur, you may experience dental damage, even tooth loss. Fortunately, we can restore an injured smile in various ways, including dentures, bridges or dental implants. But we should also attempt to limit the potential damage by taking steps to prevent dental disease during cancer treatment.
The most important of these is to brush and floss daily. Everyone should practice these hygiene tasks to remove disease-causing dental plaque, regardless of their health status. But because some natural disease-fighting mechanisms in the mouth may be disrupted during either radiation or chemotherapy, it's even more important if you're a cancer patient.
It's equally important to maintain as much as possible regular dental visits during cancer treatment. Dental cleanings provided during these visits remove any residual plaque and tartar (hardened plaque), which further lowers your disease risk.
Your dentist can better monitor your overall dental condition during frequent visits and provide as much treatment as you can tolerate. They can also enhance your protection against disease by prescribing antibacterial mouthrinses, fluoride applications or products to boost saliva production.
Some teeth and gum problems may be unavoidable; in that case, you may need post-treatment dental care to restore your oral health as needed. But caring as much for your dental health as you're able during cancer treatment could help you realize a better outcome.
In the realm of dental restorations, not all crowns are alike. And, one type isn't necessarily superior to the others. One type of crown may work better for a particular tooth, while a different crown is better suited to another.
Therefore, knowing your options can help you make a more informed choice with your dentist regarding the best crown for your needs. Here, then, is a quick primer on the main types of dental crowns used today.
Metal crowns. Early in the last century, crowns made of gold, silver or other metals were the go-to dental restoration. Because of their strength and durability, metal crowns are still used today, mainly in back teeth that encounter heavy biting forces. Their drawback: They're decidedly not the color of natural teeth and so can stand out if they're placed in the visible "smile zone."
PFM crowns. The first crowns made with dental porcelain solved the appearance problem, but couldn't adequately handle biting forces as well as metal. Out of this came the porcelain fused to metal (PFM) crown, which contains an inner core of metal overlaid with tooth-colored porcelain. Providing both strength and life-likeness, PFM crowns were immensely popular until the mid-2000s.
All-Ceramic crowns. The development of porcelains more durable than earlier versions eventually dethroned the PFM (although the latter is still used today). Sixty percent of the crowns installed in recent years are all-ceramic, many reinforced with a strength material known as Lucite. Many all-ceramic crowns reaching the 15-year mark are still in place and functioning.
All of these crowns continue to be viable options for dental patients. The biggest factor in choosing one particular crown over another is the type of tooth involved and its location. As mentioned before, metal or PFM crowns are usually better for back teeth where durability is a higher priority than aesthetics. All-ceramics work well in high-visibility front teeth that normally encounter lighter biting forces than back teeth.
Regardless of which kind eventually caps your tooth, any of today's modern crowns will function as intended. But the best crown for you will be the one that both protects your tooth and enhances your smile.

Morning tiredness, brain fog and snoring are just some of the indicators of a medical condition known as sleep apnea. And, it's worse than waking up on the wrong side of the bed—over time, sleep apnea could increase your risk for heart disease or other life-threatening conditions.
Sleep apnea occurs when air flow becomes restricted during sleep, usually by the tongue blocking the airway. As oxygen levels begin to fall, the brain signals the body to wake up to "fix" the air flow problem.
As this arousal may only last a second or two, you may not remember it when you awaken in the morning. But it can happen numerous times a night, depriving you of the deep sleep your body needs for rest and repair.
Fortunately, there are ways to treat sleep apnea. In extreme instances, you may need surgery to correct anatomical defects causing the condition. For most cases, though, the most common treatment is continuous positive airway pressure (CPAP) therapy, which consists of a portable pump delivering pressurized air through a face mask that keeps the throat open while you sleep.
Used by millions of patients, CPAP can be quite effective. Some patients, though, feel uncomfortable using a CPAP machine for various reasons. If you're one of those unhappy CPAP campers or you would like to consider a possible alternative, your dentist might have the answer: oral appliance therapy (OAT).
An OAT device is worn in the mouth during sleep to prevent the tongue from falling back against the back of the throat and blocking the airway. There are various forms of OAT appliances, but they're all custom-made by a dentist to fit an individual patient's mouth. They work best for mild to moderate sleep apnea in which the tongue is the primary culprit in airway blockage.
If you suspect you may have sleep apnea, you should undergo a complete examination by a doctor or dentist to confirm it. If you've been diagnosed with mild to moderate sleep apnea, talk to your dentist about an OAT device. You may find OAT can provide you the relief you need for a better night's sleep.

A year ago, former Australian footballer Jake Edwards got married. On television. To a woman he'd just met. No, not in a Vegas wedding chapel—it was all part of a reality TV series called Married At First Sight. Unfortunately, the marriage didn't last, which led to Edwards reevaluating his life. And one area in particular that came under his inward scrutiny was his smile.
Although otherwise possessing movie star looks, Edwards' teeth were anything but handsome: Besides a few that were chipped and cracked, his teeth overall looked small. His less-than-perfect smile was no secret, and he had plenty of offers from dentists to transform his smile.
He finally decided to do so, but with a twist: In addition to his own, he offered a full smile makeover to two other people for free (each valued at $30,000). The impetus for his makeover contest undoubtedly stems from his own lifelong experience: After years of being teased and bullied about his teeth, he knew firsthand how an unattractive smile can affect your personal and social confidence.
You too might feel the same confidence drain every time you look in the mirror. The problem, though, is that a full-scale makeover may seem out of reach financially and there aren't many Jake Edwards-style contests around to enter. But not to worry! There are a few ways to change your smile for the better without taking out a second mortgage on your house.
Teeth whitening. Even a smile with straight and perfectly formed teeth can be unattractive if those teeth are stained and dull. A professional teeth-whitening procedure can change that: Using a bleaching solution, we can turn drab and dingy teeth into a bright and dazzling smile in one sitting. With a little care and occasional touchups, your whiter smile could last for quite a while.
Bonding. We can repair mild to moderate chips and other tooth deformities simply and affordably with dental bonding. We gradually apply a resin dental material color-matched to your tooth, building it up and sculpting it to look natural. In just one sitting, a chipped tooth that once stood out like a sore thumb can regain its attractiveness.
Veneers. Many people like Edwards suffer from teeth that appear overly small or have slightly widened gaps. Problems like these and other deformities can be overcome with dental veneers, thin layers of porcelain bonded to the surfaces of teeth. Veneers can mask all manner of dental defects and truly transform a smile.
These and other affordable cosmetic procedures can truly change your smile, and many only take one visit. To learn more about your personal options, see us for a complete dental exam and consultation.

If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.
As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.
Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.
But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.
Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.
So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.
In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.
