The change from primary teeth to permanent is an announcement to the world that a boy or girl is "growing up." "Growing up," though, is still not "grown"—the new teeth are still in a period of development that can affect how we treat them if they're injured or diseased.
While a new tooth erupts with all its anatomical layers, the middle dentin is somewhat thinner than it will be after it matures. The pulp, the tooth's innermost layer, produces new dentin and gradually increases the dentin layer during this early development period. While the pulp continues to produce dentin over a tooth's lifetime, most of it occurs in these early years.
To prevent or stop any infection, we would normally perform a root canal treatment in which we remove the pulp tissue and fill the empty pulp chamber and root canals. This poses no real issue in an older tooth with mature dentin. Removing the pulp from an immature tooth, though, could interrupt dentin development and interfere with the tooth's root growth. Besides a higher risk of discoloration, the tooth could become more brittle and prone to fracture.
That's why we place a high priority on preserving a younger tooth's pulp. Rather than a root canal treatment, we may treat it instead with one of a number of modified techniques that interact less with the pulp. Which of these we use will depend on the extent of the pulp's involvement with the injury or disease.
If it's unexposed, we may use a procedure called indirect pulp therapy, where we remove most of the tooth's damaged dentin but leave some of the harder portion intact next to the pulp to avoid exposure. If, though, some but not all of the pulp is damaged, we may perform a pulpotomy: here we remove the damaged pulp tissue while leaving the healthier portion intact. We may then apply a stimulant substance to encourage more dentin production to seal the exposure.
These and other techniques can help repair an injured young tooth while preserving most or all of its vital pulp. Although we can't always use them, when we can they could give the tooth its best chance for a full life.

As Spring turns to Summer, millions of students will depart high school in the time-honored rite of passage called graduation. At the same time, quite a few of these graduates will be experiencing another maturity milestone: the eruption (coming in) of their last permanent teeth.
Typically, these are the back third molars, better known as “wisdom teeth,” emerging on either end of both the top and bottom jaws sometime between the ages of 18 and 24. Their arrival heralds the end of a long development process that began in infancy.
But this auspicious event can give rise to dental problems. Because they’re the last to come in, wisdom teeth often erupt in an environment crowded by earlier teeth. Depending on jaw size and other factors, there may not be enough room for a normal eruption.
Wisdom teeth can thus erupt out of position, creating a poor bite (malocclusion). Or they might not erupt at all—becoming stuck fully or partially within the gums and bone, a condition known as impaction. Impacted teeth can also cause problems for the adjacent teeth, damaging the roots of the second molars or disrupting the surrounding gum tissue, making them more susceptible to periodontal (gum) disease.
Because of these and other issues, impacted wisdom teeth are among the most common type of teeth removed: an estimated 10 million each year. And many of these are removed before they show signs of disease or complications as a preemptive strike against developing dental problems.
Although unnecessary surgery should always be avoided, according to some research, there’s a one in three chance that erupting wisdom teeth that are not showing signs of trouble will eventually become problematic. And the earlier they’re removed, the lower the risk of post-extraction complications.
Wisdom teeth should always be evaluated on a case by case basis. Those with obvious signs of disease or complications do require prompt treatment, including possible extraction. Others that are asymptomatic can be monitored over time: If they’re tending to become problematic, we can adjust the treatment plan accordingly. Our goal is to ensure these particular teeth signaling the end of childhood won’t detract from dental health in adulthood, so a measured approach seems to be the best and safest one.

If you have chronic jaw pain, you may be one of an estimated 10 million Americans suffering from temporomandibular joint disorders (TMD). If so, it's quite possible you're also coping with other health conditions.
TMD is an umbrella term for disorders affecting the temporomandibular (jaw) joints, muscles and adjoining tissues. The most common symptoms are limited jaw function and severe pain. Determining the causes for these disorders can be difficult, but trauma, bite or dental problems, stress and teeth clenching habits seem to be the top factors. Women of childbearing age are most susceptible to these disorders.
In recent years we've also learned that many people with TMD also experience other conditions. In a recent survey of TMD patients, two-thirds reported having three or more other health conditions, the most frequent being fibromyalgia, chronic fatigue syndrome, rheumatoid arthritis or chronic headaches. Researchers are actively exploring if any systemic connections exist between TMD and these other conditions, and how these connections might affect treatment changes and advances for all of them including TMD.
In the meantime, there remain two basic approaches for treating TMD symptoms. The most aggressive and invasive approach is to surgically correct perceived defects in the jaw structure. Unfortunately, the results from this approach have been mixed in their effectiveness, with some patients even reporting worse symptoms afterward.
The more conservative approach is to treat TMD orthopedically, like other joint problems. These less invasive techniques include the use of moist heat or ice to reduce swelling, physical therapy and medication to relieve pain or reduce muscle spasming. Patients are also encouraged to adopt softer diets with foods that are easier to chew. And dentists can also provide custom-fitted bite guards to help ease the stress on the joints and muscles as well as reduce any teeth grinding habits.
As we learn more about TMD and its relationship to other health conditions, we hope to improve diagnosis and treatment. Until then, most dentists and physicians recommend TMD patients try the more conservative treatments first, and only consider surgery if this proves unsatisfactory. It may take some trial and error, but there are ways now to ease the discomfort of TMD.

The March 27th game started off pretty well for NBA star Kevin Love. His team, the Cleveland Cavaliers, were coming off a 5-game winning streak as they faced the Miami Heat that night. Less than two minutes into the contest, Love charged in for a shot on Heat center Jordan Mickey—but instead of a basket, he got an elbow in the face that sent him to the floor (and out of the game) with an injury to his mouth.
In pictures from the aftermath, Love’s front tooth seemed clearly out of position. According to the Cavs’ official statement, “Love suffered a front tooth subluxation.” But what exactly does that mean, and how serious is his injury?
The dental term “subluxation” refers to one specific type of luxation injury—a situation where a tooth has become loosened or displaced from its proper location. A subluxation is an injury to tooth-supporting structures such as the periodontal ligament: a stretchy network of fibrous tissue that keeps the tooth in its socket. The affected tooth becomes abnormally loose, but as long as the nerves inside the tooth and the underlying bone have not been damaged, it generally has a favorable prognosis.
Treatment of a subluxation injury may involve correcting the tooth’s position immediately and/or stabilizing the tooth—often by temporarily splinting (joining) it to adjacent teeth—and maintaining a soft diet for a few weeks. This gives the injured tissues a chance to heal and helps the ligament regain proper attachment to the tooth. The condition of tooth’s pulp (soft inner tissue) must also be closely monitored; if it becomes infected, root canal treatment may be needed to preserve the tooth.
So while Kevin Love’s dental dilemma might have looked scary in the pictures, with proper care he has a good chance of keeping the tooth. Significantly, Love acknowledged on Twitter that the damage “…could have been so much worse if I wasn’t protected with [a] mouthguard.”
Love’s injury reminds us that whether they’re played at a big arena, a high school gym or an outdoor court, sports like basketball (as well as baseball, football and many others) have a high potential for facial injuries. That’s why all players should wear a mouthguard whenever they’re in the game. Custom-made mouthguards, available for a reasonable cost at the dental office, are the most comfortable to wear, and offer protection that’s superior to the kind available at big-box retailers.
If you have questions about dental injuries or custom-made mouthguards, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “The Field-Side Guide to Dental Injuries” and “Athletic Mouthguards.”
If you have a few missing teeth but can't afford dental implants or fixed bridgework, consider a removal partial denture (RPD). Although implants may be the superior choice aesthetically and functionally, an RPD can still effectively give you back your teeth.
RPDs are designed to replace one or more missing teeth but not a full arch like a full denture. Considered a permanent restoration, RPDs are also more durable than transitional "flippers," denture appliances that are flexible and light enough to be flipped out of the mouth with a flick of the tongue.
The key to both their affordability and durability is vitallium, a strong but lightweight metal alloy most often used in their frame construction. To it we attach artificial teeth usually made of porcelain or glass-filled resins that occupy the precise location of the missing teeth on the gum ridge. The artificial teeth and frame are surrounded by gum-colored plastic for a more natural look.
Each RPD is custom-made depending on the number and location of the missing teeth. Its construction will focus on minimizing any rocking movement of the RPD during chewing or biting. Too much of this movement could damage the adjacent teeth it's attaching to and cause the appliance to be uncomfortable to wear. We can stabilize the frame by precisely fitting it between teeth to buttress it. We also insert small rests or clasps made of vitallium at strategic points to grip teeth and minimize movement.
RPDs do have some downsides: their unique attachment with teeth encourages the accumulation of dental plaque, the thin bacterial film that's the leading cause of tooth decay and periodontal (gum) disease. These diseases can affect your remaining teeth's health and stability, which could in turn disrupt the fit of the RPD. Also, too much movement of the appliance can make the teeth to which it's attached become more mobile. It's important, then, if you wear a RPD to remove it daily for cleaning (and to thoroughly brush and floss your natural teeth), and to remove it at night to give the attaching teeth a rest.
A RPD can give you back the teeth you've lost for many years to come—if you take care of it. Maintaining both your RPD and the rest of your teeth and gums will help extend the life and use of this effective and affordable replacement restoration.
