Back to School? Remember Your Dental Homework!

September 3rd, 2025

It’s a busy time of year. Book lists! Supplies! New clothes! (How did they outgrow those shoes already?) And while you’re preparing your family’s list of back-to-school necessities, here are a few essential reminders to help your child begin the school year with a healthy smile.

  • Review

It never hurts to review the basics before the start of the school year, and that holds true for dental care as well! Make sure your child is brushing two minutes twice a day, and using floss or another interdental tool to clean between the teeth. If his toothbrush has been in use since the end of the last school year, it’s probably time to replace it. Bristles are at their best for about three months—after that, they become frayed and worn, and can’t remove plaque as effectively.

  • School Supplies for Braces Wearers

If your child is going to school with braces for the first time, send her off with the tools she needs. A travel-sized toothbrush and tube of toothpaste are perfect for a quick brushing after lunch, while dental floss and a threader or dental picks will take care of any after-lunch particles lurking in brackets and wires. Orthodontic wax is a great product to have on hand if a wire or bracket is causing irritation. If your child uses clear aligners or a retainer, make sure a protective case is always close by, ready to use every time the appliance is removed. And it’s a good idea to include the number of your dentist and orthodontist in her contacts in case of emergency.

  • Exams

If your school requires a dental exam before the start of classes, be sure to make your appointment at our Dallas office now! Regular checkups with Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani are vital for preventing small problems from becoming bigger ones, and a professional cleaning will remove the plaque even careful brushing can miss.

A positive, confident start can set the tone for the academic year, so your homework might include monitoring summer reading, providing required supplies, and making sure your child is well-rested and ready to go. You can also help your child to a positive, confident start by monitoring brushing habits, providing the necessary tools for appliance-wearers, and making sure your child is up-to-date with dental exams and cleanings. Because entering the classroom with a beaming, healthy smile—that’s an A+ way to begin the school year!

The Root of the Matter

August 27th, 2025

A strong, healthy smile is built on a strong, healthy foundation. Let’s take a moment to explore just what creates that foundation—your roots.

The Root of the Matter

The visible part of your tooth is called the crown. And while we spent the great majority of our time thinking about what goes on above the gum line—brushing, flossing, whitening, sealing, preventing cavities—the roots, the parts of the teeth below the surface, are also essential to our dental health.

  • What’s inside the root?

The inside of each tooth holds pulp, which is living tissue made of nerves, blood vessels, and connective tissue. The nerves in the pulp allow us to feel pain when a tooth is damaged, decayed, or infected. Tiny blood vessels provide oxygen and nutrients to the cells.

The inside of each root also contains pulp, located in one or more root canals. These canals are small tunnels that travel from the pulp chamber to the tip of each root. Nerves and blood vessels connect pulp tissue to the nervous and circulatory systems in the body, entering and exiting the tooth from very small openings in the root tip.

  • What’s outside the root?

On the outside, while roots look like crowns, they’re covered with a different protective surface. Roots are covered by cementum rather than enamel. This is a hard tissue, but not as hard as enamel. But cementum has another advantage—it not only helps protect our teeth, it helps them stay anchored in our jaws. (More on this below.)

  • How many roots are we talking about?

The number varies, not just depending on the tooth, but depending on the individual. Most adults have 32 adult teeth: eight incisors, four canines, eight premolars, eight molars, and four wisdom teeth, or third molars. Because the number of wisdom teeth can range from four to zero, though, that total can be smaller.

Rooted to the Spot

The reason that you can rely on your teeth for a lifetime of chewing, biting, and grinding food is the fact that they’re so securely anchored in the jaw.

  • Alveolar bone in the jaw contains a socket for each tooth.
  • A thin layer of connective tissue called the periodontal ligament lines the socket and surrounds each root. It’s filled with fibers that attach to the root’s cementum covering and to the alveolar bone, holding the tooth securely in place.
  • The periodontal ligament not only anchors the tooth, it cushions it from the daily pressure of biting and chewing.
  • Finally, the gums surround the teeth and bone, protecting them from bacteria and plaque.

Even though this design is very secure, there are situations where the root becomes vulnerable. In that case, you should see Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani at our Dallas office right away. Our goal is for you to keep your teeth healthy and strong, and for a lifetime!

Take Your Pick!

August 20th, 2025

Before electric toothbrushes, before dental floss, before fluoride rinses, in fact, before recorded history, people who cared about their dental health had one primary tool—the toothpick. Ancient bronze toothpicks, bejeweled Renaissance picks, and the more humble modern wooden picks have been instrumental in promoting dental hygiene for centuries.

And, while that clean, simple design is still a good one, modern technology has found a way to build an even better toothpick. Today’s interdental picks not only dislodge food particles effectively, but now gum stimulation, cleaner orthodontic appliances, and fresher breath are available literally at our fingertips. Most important, these picks are just as effective as floss for removing plaque.

  • Wood? Still Good!

Today’s softer wooden picks come in several shapes designed to fit comfortably and snugly between the teeth. Using a gentle in-and-out motion, you can clean between your teeth as you remove plaque from the tooth surface. But that’s not the only benefit! As you move the wide end of the pick up and down between teeth and gums, you are actually stimulating your gum tissue as well.  They even come with mint flavoring to refresh your mouth as you clean. And, of course, wood and bamboo picks are biodegradable.

  • Plastic? Fantastic!

If you’d like something a little more yielding than wooden dental picks, you have options. Soft dental picks are available that use rubber “bristles” on a plastic stem to gently ease their way between teeth. The heads are available in different diameters to accommodate tight or wide spacing between the teeth. Straight or curved stems provide the accessibility you need. If you have latex allergies, be sure to choose a rubber product that is latex-free.

  • Interproximal Brushes? Here’s What the Buzz Is

You might have missed these miniature brushes in the dental care aisle, but they are worth looking for. Interproximal brushes have small cone-shaped heads with nylon bristles for cleaning food particles and plaque from between the teeth. They are good for more than one use, and some are available with angled or bendable handles for hard-to-reach spots. They come in different diameters, from wide to extremely fine, to suit the spacing of your teeth. Interdental brushes are especially useful for braces wearers, who can use these clever tools to clean tight, tricky areas under wires and around brackets.

Even though bronze, bejeweled, or golden toothpicks aren’t available in the dental aisle of the local drugstore, increased efficiency and function are well worth the trade-off. If for any reason you have trouble flossing, or if you like the idea of massaging your gums as you clean your teeth, or if you wear braces, or if you want a burst of mint flavor—for any number of reasons today’s dental picks are worth a try. Talk to Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani at your next visit to our Dallas office, and we’ll be happy to give you some recommendations. 

Dental Fear in Children: Brought on by parents?

August 13th, 2025

A study conducted in Washington State in 2004 and another conducted in Madrid, Spain in 2012 both reported findings that support a direct relationship between parents’ dental fear and their child’s fear of the dentist.

The Washington study examined dental fear among 421 children ages 0.8 to 12.8 years old. They were patients at 21 different private pediatric dental practices in western Washington state. The Spanish study observed 183 children between the ages of seven and 12 as well as their parents.

The Washington study used responses from both parents and the Dental Sub-scale of the Child Fear Survey Schedule. The survey consisted of 15 questions, which invited answers based on the child’s level of fear. The scale was one to five: one meant the child wasn’t afraid at all, and five indicated he or she was terrified. The maximum possible points (based on the greatest fear) was 75.

Spanish researchers found a direct connection between parental dental fear levels and those among their kids. The most important new discovery from the Madrid study was that the greater the fear a father had of going to the dentist, the higher the level of fear among the other family members.

Parents, but especially fathers, who feared dental procedures appeared to pass those fears along to every member of the family. Parents can still have some control over fear levels in their children. It is best not to express your own concerns in front of kids; instead, explain why going to the dentist is important.

Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team work hard to make your child’s visit at our Dallas office as comfortable as possible. We understand some patients may be more fearful than others, and will do our best to help ease your child’s anxiety.
