As your dental provider, we're always alert for signs of tooth decay or periodontal (gum) disease, the two leading causes of tooth loss. But we're also watching for less common conditions that could be just as devastating.
Root resorption falls into this latter category: it occurs when a tooth's root structure begins to break down and dissolve (or resorb). It's a normal process in primary ("baby") teeth to allow them to loosen and give way when permanent teeth are ready to erupt.
It's not normal, though, for permanent teeth. Something internally or—more commonly—externally causes the root structure to break down. External resorption usually occurs at the neck-like or cervical area of a tooth around the gum line. Known as external cervical resorption (ECR), it can first appear as small, pinkish spots on the enamel. These spots contain abnormal cells that cause the actual damage to the root.
We don't fully understand how root resorption occurs, but we have identified certain factors that favor its development. For example, it may develop if a person has experienced too much force against the teeth during orthodontic treatment. Injury to the periodontal ligaments, teeth-grinding habits or some dental procedures like internal bleaching may also contribute to later root resorption.
Early diagnosis is a major part of effective treatment for root resorption. Because it's usually painless and easily overlooked, resorption is often too difficult to detect in its early stages without x-rays—a good reason for regular dental exams. Beginning spots or lesions are usually small enough to surgically remove the tissue cells causing the damage and then filled with a tooth-colored filling material. If it has advanced further, we may also need to perform a root canal treatment.
At some point, the damage from root resorption can be too great, in which case it might be best to remove the tooth and replace it with a dental implant or similar restoration. That's why catching root resorption early through regular dental exams can give you the edge for saving your tooth.

April is National Stress Awareness Month. But what does stress have to do with dentistry? According to the American Academy of Sleep Medicine, if you have a Type A personality or are under a lot of stress, you are more likely to suffer from a condition called bruxism, which means you habitually grind or gnash your teeth. One in ten adults grind their teeth, and the rate is much higher in stressful professions. In fact, the bruxism rate is seven times higher among police officers!
Many people grind their teeth in their sleep without realizing it, so how would you know if you are a "sleep bruxer"? If your spouse frequently elbows you in the ribs because of the grinding sounds you make, that could be your first clue. Unfortunately, dental damage is another common sign. Some people find out they are nighttime teeth grinders only when they are examined by a dentist since bruxing often leads to wear patterns on the teeth that only happen because of this behavior. Other complications can also develop: The condition can interfere with sleep, result in headaches and cause soreness in the face, neck or jaw. Chronic or severe nighttime teeth grinding can damage dental work, such as veneers, bridgework, crowns and fillings, and can result in teeth that are worn down, chipped, fractured or loose.
The most common treatment is a custom-made night guard made of high-impact plastic that allows you to sleep while preventing your upper and lower teeth from coming into contact. Although a night guard will protect your teeth and dental work, it won't stop the grinding behavior. Therefore, finding and treating the cause should be a priority.
The Bruxism Association estimates that 70 percent of teeth grinding behavior is related to stress. If you are a bruxer, you can try muscle relaxation exercises, stretching and breathing exercises, stress reduction techniques and, where feasible, any lifestyle changes that can allow you to reduce the number of stressors in your life. Prescription muscle relaxants may also help. In addition, teeth grinding may be related to sleep apnea. This possibility should be investigated since sleep apnea can have some serious health consequences—we offer effective treatments for this condition as well.
We can spot signs of bruxism, so it's important to come in for regular dental checkups. We look for early indications of dental damage and can help you protect your smile. If you have questions about teeth grinding or would like to discuss possible symptoms, please contact our office or schedule an appointment for a consultation.

As the host of America's Funniest Home Videos on ABC TV, Alfonso Ribeiro has witnessed plenty of unintentional physical comedy…or, as he puts it in an interview with Dear Doctor–Dentistry & Oral Health magazine, "When people do stuff and you're like, 'Dude, you just hurt yourself for no reason!'" So when he had his own dental dilemma, Alfonso was determined not to let it turn onto an "epic fail."
The television personality was in his thirties when a painful tooth infection flared up. Instead of ignoring the problem, he took care of it by visiting his dentist, who recommended a root canal procedure. "It's not like you wake up and go, 'Yay, I'm going to have my root canal today!'" he joked. "But once it's done, you couldn't be happier because the pain is gone and you're just smiling because you're no longer in pain!"
Alfonso's experience echoes that of many other people. The root canal procedure is designed to save an infected tooth that otherwise would probably be lost. The infection may start when harmful bacteria from the mouth create a small hole (called a cavity) in the tooth's surface. If left untreated, the decay bacteria continue to eat away at the tooth's structure. Eventually, they can reach the soft pulp tissue, which extends through branching spaces deep inside the tooth called root canals.
Once infection gets a foothold there, it's time for root canal treatment! In this procedure, the area is first numbed; next, a small hole is made in the tooth to give access to the pulp, which contains nerves and blood vessels. The diseased tissue is then carefully removed with tiny instruments, and the canals are disinfected to prevent bacteria from spreading. Finally, the tooth is sealed up to prevent re-infection. Following treatment, a crown (cap) is usually required to restore the tooth's full function and appearance.
Root canal treatment sometimes gets a bad rap from people who are unfamiliar with it, or have come across misinformation on the internet. The truth is, a root canal doesn't cause pain: It relieves pain! The alternatives—having the tooth pulled or leaving the infection untreated—are often much worse.
Having a tooth extracted and replaced can be costly and time consuming…yet a missing tooth that isn't replaced can cause problems for your oral health, nutrition and self-esteem. And an untreated infection doesn't just go away on its own—it continues to smolder in your body, potentially causing serious problems. So if you need a root canal, don't delay!

Your teeth were meant to shine! Tooth enamel’s polished translucence, framed by the dentin layer beneath it, has a way of vibrantly catching the light when you smile. But tooth wear and structural changes as you age can dim that shine. Add to that staining caused by foods and beverages or disease and your smile could further lose its luster.
On your supermarket or pharmacy oral hygiene aisle you’ll find dozens of products promising to restore that lost luster, including toothpastes, whitening kits or even chewing gum. While such products work to some degree, our dental office may have the right solution for you: a safe and effective treatment for whitening teeth.
Why see us for teeth whitening? For one, professional whitening solutions contain a higher concentration of bleaching agent (usually 35-45% hydrogen peroxide) than home kits. We usually apply it in a gel form directly to the teeth while using barrier devices like dams to protect the lips and other soft tissue from irritation. We may then apply heat or light to the applied gel to enhance the release of peroxide into your enamel.
This professional procedure can often give you a brighter smile in fewer sessions than a home whitening kit — and it may last longer. What’s more, we can control the level of brightness to produce only a subtle change or a dazzling “Hollywood” smile — whatever your preference.
Like a home kit, this procedure bleaches staining on the outer surface of enamel, known as extrinsic staining. But you can also have discoloration deep within a tooth, known as intrinsic staining, caused by a variety of reasons like tetracycline use early in life or complications from a root canal treatment. Home kits or even the professional treatment described above can’t whiten intrinsic staining.
For intrinsic staining you’ll need a special procedure that places a bleaching agent inside the tooth. Depending on the extent of staining the procedure could require more than one session.
To find out what kind of discoloration you have, visit us for a full examination. We’ll then be able to give you your options for putting the shine back in your smile.

While children are less likely than adults to experience periodontal (gum) disease, the same can't be said for tooth decay. One aggressive form of decay called early childhood caries (ECC) can have a profound effect on a child's dental development and future health.
That's why dentists who treat young children often use a variety of preventive measures to reduce the risk of ECC and other dental diseases. One popular method is dental sealants, dental material coatings applied to the biting surfaces of teeth that fill in the naturally occurring pits and crevices. These areas are highly susceptible to plaque formation, a bacterial biofilm of food particles that tends to accumulate on teeth. It's the bacteria that live in plaque that are most responsible for the formation of tooth decay.
Roughly one third of children between the ages of 6 and 11 have received some form of dental sealant. It's a quick and painless procedure applied during a routine office visit. The dentist brushes the sealant in liquid form on the teeth, and then hardens it with a special curing light. It's common for children to begin obtaining sealant protection as their molars begin to come in.
With their increased popularity among dentists, researchers have conducted a number of studies to see whether dental sealants have a measurable effect reducing tooth decay. After reviewing the cases of thousands of children over several years, many of these studies seemed to show that children who didn't receive sealants were more than twice as likely to get cavities as children who did.
As evidence continues to mount for dental sealants' effectiveness protecting young children from decay, both the American Dental Association and the American Academy of Pediatric Dentistry now recommend it for all children. Not only can sealants help preserve children's teeth now, but they can reduce future costs for dental treatment that results from tooth decay.
