Ah, the baby teeth: those cute little pearl buttons that start to appear in a child’s mouth at around 6 to 9 months of age. Like pacifiers and bedtime stories, they’ll be gone before you know it — the last usually disappear by age 10-13. So if the dentist tells you that your young child needs a root canal, you might wonder why — isn’t that tooth going to be lost anyway?
The answer is yes, it is — but while it’s here, it has some important roles to play in your child’s development. For one thing, baby teeth perform the same functions in kids as they do in adults: Namely, they enable us to chew, bite, and speak properly. The primary teeth also have a valuable social purpose: they allow us to smile properly. If a baby tooth is lost prematurely at age 6, the child may suffer detrimental effects for five years or more — and that’s a long time for someone so young!
Even more important, baby teeth have a critical function in the developing mouth and jaw: Each one holds a space open for the permanent tooth that will eventually replace it — and it doesn’t “let go” until the new tooth is ready to come in. If a primary (baby) tooth is lost too soon, other teeth adjacent to the opening may drift into the empty space. This often means that the permanent teeth may erupt (emerge above the gum line) in the wrong place — or sometimes, not at all.
The condition that occurs when teeth aren’t in their proper positions is called malocclusion (“mal” – bad; “occlusion” – bite). It can cause problems with eating and speaking, and often results in a less-than-perfect-looking smile. It’s the primary reason why kids get orthodontic treatment — which can be expensive and time-consuming. So it makes sense to try and save baby teeth whenever possible.
Procedures like a root canal — or the similar but less-invasive pulpotomy — are often effective at preserving a baby tooth that would otherwise be lost. But if it isn’t possible to save the tooth, an appliance called a space maintainer may help. This is a small metal appliance that is attached to one tooth; its purpose is to keep a space open where the permanent tooth can come in.
If your child is facing the premature loss of a primary tooth, we will be sure to discuss all the options with you. It may turn out that preserving the tooth is the most cost-effective alternative in the long run. If you have questions about your child’s baby teeth, please contact us or schedule an appointment for a consultation.
The traditional way to restore a tooth with an artificial crown takes several weeks and multiple office visits: from tooth preparation and impression molding to crown production by a dental laboratory, followed by adjustments and cementing. Now, there’s an alternative that reduces this process to a fraction of the time, and all from your dentist’s office.
Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) is a digital system that enables dentists to create dental restorations with laboratory-grade materials in minutes rather than weeks. As it continues to innovate, you’ll see more and more dentists investing in the new technology for their patients.
A crown restoration with CAD/CAM begins like any other with decay removal and preparation of the tooth. It diverges, though, from the traditional in how an impression of your teeth and gums is obtained: instead of rubber-like molding materials to create a physical impression, we lightly dust the mouth interior with a reflective powder. Using a scanning wand, the reflective powder allows us to capture multiple, detailed images of your mouth that the CAD/CAM computer transforms into an accurate three-dimensional model.
We use the model to first assess if the tooth has been effectively prepared for a restoration. If so, the design feature of the system will provide us with thousands of tooth forms to choose from to match with your natural teeth. You’ll be able to view the proposed size and shape of the new crown via computer simulation before signing off on the design.
Next is the actual manufacture of the crown that takes place right in the dentist’s office. A pre-formed block of ceramic material is inserted in the milling equipment where, following the pre-determined computer design, the milling heads carve the ceramic block. After milling, we fine-tune the crown surface and apply stains or glazes fired to create a life-like color and texture that matches your natural teeth. We can then adjust the crown in your mouth and permanently affix it to the tooth.
While much of the CAD/CAM system is automated, ultimate success still depends on the dentist’s expertise and artistry. CAD/CAM enhances those skills with greater precision and in much less time than traditional crowns. It’s certainly a growing option for many people to restore the form and function of decayed teeth.

In many ways, the teenage years are the best time to have orthodontic treatment. It’s a good time emotionally because your teen is likely to have friends who also wear braces; orthodontic treatment becomes a rite of passage they can go through together. It’s also advantageous in a physical sense because all 20 baby teeth have come out, and most of the 32 adult teeth (except the 4 wisdom teeth) have emerged. At the same time, especially with younger teens, jaw growth is not yet complete — allowing orthodontists to harness the growing body’s natural adaptability. We can use a variety of appliances to do that — some of which weren’t around a generation ago!
In many cases, traditional metal braces are still the best way to achieve the desired results. However, these are not the “train tracks” of old. Braces are smaller and lighter, with brackets that are cemented to the front surfaces of teeth rather than to bands that encircle the entire tooth (except in the very back). Braces can be made much less noticeable by using ceramic brackets that are clear or tooth-colored; however, ceramic brackets are easier to break than metal. An even stealthier way to undergo orthodontic treatment is with clear aligners. These removable clear plastic “trays” are custom made with the help of computer software that divides the treatment process into two-week stages. After each two-week period, the tray is changed and the next stage of movement takes place until the teeth are in correct alignment. The Invisalign system has two modifications especially for teens: “eruption tabs” that hold space open for emerging molars, and “compliance indicators” that can tell parents and orthodontists if the teen is keeping the trays in for the prescribed amount of time. We’d be happy to discuss whether clear aligners would be an option for your child.
Keeping It Clean
No matter which type of appliance is used, oral hygiene becomes even more important during orthodontic treatment. Wearing braces presents special challenges in terms of keeping teeth clean; however, it’s extremely important to do an effective job every day so that gums do not become inflamed and cavities do not develop. It’s far easier to clean teeth with clear aligners, which can be removed, but the aligners themselves can build up bacteria, leading to the same types of oral health issues if they are not cleaned each day.
Making It Count
Another way in which orthodontic treatment will not vary regardless of the type of appliance chosen is the necessity of a retention phase. Everyone who has their teeth straightened (and this goes for adults and younger kids, too) must wear a retainer to hold the teeth in their new and improved alignment while new bone grows around them. Yes, braces are easier to wear than they used to be… but no one wants to wear them twice!
