Children have a lot of energy that's often channeled through physical activities and sports. Unfortunately, this also increases their risk of injuries, particularly to their teeth.
Injuries to the mouth can endanger permanent teeth's survival. For an older tooth, a root canal treatment might be in order. Not so, though, for a pre-adolescent tooth, even if it is permanent.
A young permanent tooth is still developing dentin, the large layer just below the enamel. This growth depends on the connective tissue, blood vessels and nerves within the pulp in the center of the tooth. Because a root canal treatment removes all of this tissue, it could stunt dentin and root growth and endanger the tooth's future.
Instead, we may need to treat it with one of a number of modified versions of a root canal, depending on what we find. If the tooth's pulp is unexposed, for example, we may need only to remove the damaged dentin, while still leaving a barrier of dentin to protect the pulp. We then apply an antibacterial agent to minimize infection and fill in the area where we've removed tooth structure.
If some of the pulp is exposed, we may perform a pulpotomy to remove just the affected pulp and any overgrown tissue. We then place a substance that encourages dentin growth and seal it in with a filling. If we go deeper toward the root end, we might also perform procedures that encourage the remaining pulp to form into a root end to stabilize the tooth.
If the entire pulp has been damaged beyond salvage, we may then turn to a procedure called an apexification. In this case we clean out the pulp chamber; at the root end we place mineral trioxide aggregate (MTA), a growth stimulator that encourages surrounding bone to heal and grow. We then fill in the root canals and chamber with a special filling called gutta percha to seal the tooth.
The deeper we must penetrate into the pulp, the higher the chances the young tooth's dentin and roots won't form properly, leading to later problems and possible loss. But by employing the appropriate one of these methods, we can minimize the risk and give your child's damaged tooth a fighting chance.

Dental veneers, thin layers of porcelain bonded to chipped, stained or slightly crooked teeth, are an effective and affordable way to transform your smile. Their color, translucence and shape blend so well with the rest of your teeth that it's often difficult to tell them apart.
But traditional veneers have one drawback: although they're less than a millimeter in width, they can still appear bulky on unprepared teeth. To help them look more natural, we often have to remove some of the enamel layer from the tooth surface. Enamel doesn't grow back, so this alteration is permanent and the prepared teeth will require a restoration from then on.
But you may be able to avoid this—or at least keep the alteration to a minimum—with no-prep or minimal-prep veneers, two new exciting choices in cosmetic dentistry. About the width of a contact lens, we can bond these much thinner veneers to teeth with virtually no preparation at all or, in the case of a minimal-prep veneer, needing only an abrasive tool to reshape and remove only a tiny bit of the enamel.
These ultra thin veneers are best for teeth with healthy enamel, and can be placed in as few as two appointments. And besides being less invasive, the procedure is reversible—we can remove them and you can return to your original look without any follow-up restoration. One caveat, though: because of the strong bonding process used, it's not always easy to remove them.
Although their thinness makes it possible to avoid or minimize alterations, there are some dental situations like oversized teeth that may still require extensive tooth preparation. With some poor bites (malocclusions) orthodontic treatment to straighten the teeth may also be needed first.
All in all, though, no-prep or minimal-prep veneers could help you avoid the permanent tooth alteration that usually accompanies their thicker cousins. What's more, you'll have the beautiful, transformed smile that veneers can achieve.

It's no secret that many of Hollywood's brightest stars didn't start out with perfectly aligned, pearly-white teeth. And these days, plenty of celebs are willing to share their stories, showing how dentists help those megawatt smiles shine. In a recent interview with W magazine, Emma Stone, the stunning 28-year-old star of critically-acclaimed films like La La Land and Birdman, explained how orthodontic appliances helped her overcome problems caused by a harmful habit: persistent thumb sucking in childhood.
“I sucked my thumb until I was 11 years old,” she admitted, mischievously adding “It's still so soothing to do it.” Although it may have been comforting, the habit spelled trouble for her bite. “The roof of my mouth is so high-pitched that I had this huge overbite,” she said. “I got this gate when I was in second grade… I had braces, and then they put a gate.”
While her technical terminology isn't quite accurate, Stone is referring to a type of appliance worn in the mouth which dentists call a “tongue crib” or “thumb/finger appliance.” The purpose of these devices is to stop children from engaging in “parafunctional habits” — that is, behaviors like thumb sucking or tongue thrusting, which are unrelated to the normal function of the mouth and can cause serious bite problems. (Other parafunctional habits include nail biting, pencil chewing and teeth grinding.)
When kids develop the habit of regularly pushing the tongue against the front teeth (tongue thrusting) or sucking on an object placed inside the mouth (thumb sucking), the behavior can cause the front teeth to be pushed out of alignment. When the top teeth move forward, the condition is commonly referred to as an overbite. In some cases a more serious situation called an “open bite” may develop, which can be difficult to correct. Here, the top and bottom front teeth do not meet or overlap when the mouth is closed; instead, a vertical gap is left in between.
Orthodontic appliances are often recommended to stop harmful oral habits from causing further misalignment. Most appliances are designed with a block (or gate) that prevents the tongue or finger from pushing on the teeth; this is what the actress mentioned. Normally, when the appliance is worn for a period of months it can be expected to modify the child's behavior. Once the habit has been broken, other appliances like traditional braces or clear aligners can be used to bring the teeth into better alignment.
But in Stone's case, things didn't go so smoothly. “I'd take the gate down and suck my thumb underneath the mouth appliance,” she admitted, “because I was totally ignoring the rule to not suck your thumb while you're trying to straighten out your teeth.” That rule-breaking ended up costing the aspiring star lots of time: she spent a total of 7 years wearing braces.
Fortunately, things worked out for the best for Emma Stone: She now has a brilliant smile and a stellar career — plus a shiny new Golden Globe award!
