Baby (primary) teeth look and function much like their permanent counterparts. Besides having a visible crown, they also have roots that maintain contact with the jawbone.
But there are some differences, the biggest one being the normal process whereby primary tooth roots dissolve or, in dental terms, resorb. Root resorption eventually leads to the tooth coming loose to make way for the permanent tooth.
Adult tooth roots can also resorb — but it's decidedly not normal. If adult root resorption isn't promptly treated, it could also lead to tooth loss — but there won't be an incoming tooth to take its place.
Although it can begin inside a tooth, adult root resorption usually begins on the outside. One type, external cervical resorption (ECR), begins around the neck-like area of the tooth not far below the gum line. Its initial signs are small pink spots where the tooth enamel has eroded; those pink cells within the space are doing the damage.
We don't fully understand the mechanism behind ECR, but there are some factors that often contribute. People with periodontal ligament damage or trauma, sometimes due to too much force applied during orthodontic treatment, have a high risk of ECR. Some bleaching techniques for staining inside a tooth may also be a factor.
The key to treating ECR is to detect it as early as possible before it does too much root damage. Regular checkups with x-rays play a pivotal role in early detection. Advanced stages of ECR might require more advanced diagnostics like a cone beam computed tomography (CBCT) scan to fully assess the damage.
If the lesion is small, we can surgically remove the cells causing the damage and fill the site with a tooth-colored filling. If ECR has spread toward the pulp, the tooth's inner nerve center, we may also need to perform a root canal treatment.
Either of these methods intends to save the tooth, but there is a point where the damage is too great and it's best to remove the tooth and replace it with a life-like dental implant or other restoration. That's why it requires vigilance through regular, semi-annual dental visits to detect the early signs of root resorption before it's too late.

As if the preteen years didn’t give kids and their parents enough to think about, new oral health concerns loom on the horizon. Along with major changes to the body, brain and emotions, additional risk factors for tooth decay and gum disease appear during adolescence — the period of development starting around age 10 and extending through the teen years that marks the transition from childhood to adulthood.
Even with declining rates of tooth decay across the nation, the cavity rate remains high during adolescence. According to the American Academy of Pediatrics, 1 in every 5 adolescents has untreated tooth decay. What’s more, the onset of puberty — usually beginning around age 10-11 in girls and 11-12 in boys — brings changes in hormone levels that can affect gum health.
We all have millions of microorganisms in our mouth, representing hundreds of different species of mostly helpful, but some harmful, bacteria. Research has shown that total oral bacteria increases between ages 11 and 14, and new types of bacteria are introduced, including some that are not friendly to teeth and gums. Some unfamiliar microbes trigger an exaggerated inflammatory response to dental plaque, so gum bleeding and sensitivity are experienced by many children in this age group. In fact, “puberty gingivitis,” which peaks around age 11-13, is the most common type of gum disease found during childhood.
A combination of hormones, lifestyle changes and poor oral hygiene habits raises the risk of oral health problems among adolescents. A more independent social life may be accompanied by a change in eating habits and easier access to snacks and beverages that are sugary, acidic (like sports drinks and soda) or full of refined carbohydrates — none of which are tooth-healthy choices. And as children move toward greater independence, parents are less likely to micromanage their children’s personal care, including their oral hygiene routines. Good oral hygiene can keep dental plaque at bay, lowering the chance of having gingivitis and cavities. But let’s face it: Adolescents have a lot to think about, and keeping up with their oral health may not be a priority.
To help your preteen stay on top of their oral health, keep healthy snacks at home for your children and their friends and make sure you are well stocked with supplies such as new toothbrushes, floss and toothpaste. In addition, most preteens (and teens) can benefit from gentle reminders about oral hygiene routines.
For optimal oral health through all stages of life, make sure your preteen keeps up with professional teeth cleanings and exams, and talk with us about whether fluoride treatments or sealants may be appropriate for your child.

How many actresses have portrayed a neuroscientist on a wildly successful TV comedy while actually holding an advanced degree in neuroscience? As far as we know, exactly one: Mayim Bialik, who plays the lovably geeky Amy Farrah Fowler on CBS' The Big Bang Theory… and earned her PhD from UCLA.
Acknowledging her nerdy side, Bialik recently told Dear Doctor magazine, “I'm different, and I can't not be different.” Yet when it comes to her family's oral health, she wants the same things we all want: good checkups and great-looking smiles. “We're big on teeth and oral care,” she said. “Flossing is really a pleasure in our house.”
How does she get her two young sons to do it?
Bialik uses convenient pre-loaded floss holders that come complete with floss and a handle. “I just keep them in a little glass right next to the toothbrushes so they're open, no one has to reach, they're just right there,” she said. “It's really become such a routine, I don't even have to ask them anymore.”
As many parents have discovered, establishing healthy routines is one of the best things you can do to maintain your family's oral health. Here are some other oral hygiene tips you can try at home:
Brush to the music — Plenty of pop songs are about two minutes long… and that's the length of time you should brush your teeth. If brushing in silence gets boring, add a soundtrack. When the music's over — you're done!
Flossing can be fun — If standard dental floss doesn't appeal, there are many different styles of floss holders, from functional ones to cartoon characters… even some with a martial-arts theme! Find the one that your kids like best, and encourage them to use it.
The eyes don't lie — To show your kids how well (or not) they are cleaning their teeth, try using an over-the-counter disclosing solution. This harmless product will temporarily stain any plaque or debris that got left behind after brushing, so they can immediately see where they missed, and how to improve their hygiene technique — which will lead to better health.
Have regular dental exams & cleanings — When kids see you're enthusiastic about going to the dental office, it helps them feel the same way… and afterward, you can point out how great it feels to have a clean, sparkling smile.
