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!

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. 

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.

August 22 is National Tooth Fairy Day! If the Tooth Fairy is a treasured part of your child’s life, you’re just in time to celebrate! But what to do when the Tooth Fairy doesn’t arrive on schedule—when baby teeth stay longer than expected or are lost too soon? 

A baby’s 20 baby teeth tend to come in within a fairly predictable time frame. The bottom central incisors in the very front of your baby’s mouth typically make their appearance first, when your baby is around six to ten months old. Over the next few years, the remaining incisors, canines, and first molars arrive. Last on the scene are the second molars, which usually show up between the ages of 23-33 months. 

Just as baby teeth follow a pattern coming in, they tend to follow the same pattern falling out. The front teeth begin to wiggle and loosen around age six or seven, while the last of the baby teeth, the canines and second molars, are often lost between the ages of ten and 12. 

Baby teeth fall out as the adult teeth below them push up as they erupt. The top of the new tooth puts pressure on the root of the baby tooth, gradually dissolving it. As the root grows smaller and can’t anchor the tooth, the tooth begins to wiggle and eventually becomes loose enough to fall out. This leaves the adult tooth perfectly placed to grow into its proper position.

Sometimes, though, teeth linger far past their fall-out date. Sometimes, because of decay or trauma, they are lost much too early. In either case, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani can provide treatment to protect little smiles now and to ensure that there’s space for the permanent teeth to erupt and align correctly.

Teeth Which Overstay Their Welcome

If that baby tooth never gets wiggly, the team at Dallas Dental Arts can help! When baby teeth stubbornly hang on, adult teeth can erupt behind them, creating a double row of teeth commonly known as “shark teeth.” These permanent teeth can become crowded or misaligned as they try to fit in any space available. Or a baby tooth can block an adult tooth from erupting at all. When that baby tooth just isn’t budging, an extraction will create space for the permanent tooth to erupt.

Extracting a baby tooth is generally a straightforward procedure because primary teeth have very small roots. Your child’s dental team at Dallas Dental Arts are experts in helping you prepare your child for the procedure in a gentle, reassuring, and age-appropriate way. 

Often, a local anesthetic is all that’s necessary for a simple extraction, but if you feel sedation would better fit your child’s needs, discuss sedation options with your dentist. After the extraction, you’ll be given clear information on how to deal with pain and swelling, which foods and drinks are best while the extraction site heals, and how to protect the area.

Teeth Which Exit Too Early

In the case of decay or trauma, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani will do everything possible to save the tooth. When decay is so extensive that there’s not enough structure left to hold a filling or crown, or when there’s an infection in or around the tooth, or when an accident or injury has caused serious damage, extraction might be the healthiest option. Depending on your child’s age, further treatment might be needed afterward to protect future smiles. 

Besides their roles in eating and speaking, baby teeth save space for permanent teeth. Whenever a child loses a primary tooth too soon, the family dentist will be on the lookout for potential future orthodontic problems. If remaining baby teeth shift, taking up part of the empty space left behind by the lost tooth, the adult teeth below won’t have the space they need to erupt properly. Permanent teeth might come in at an awkward angle or in the wrong place. 

In this case, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani might recommend a space maintainer. Space maintainers are small, custom-designed appliances which prevent the remaining baby teeth from shifting position while holding space open for the permanent tooth to arrive right on schedule and right where it belongs. 

It’s comforting to have charts which let us know when little teeth will typically come in and when they will typically fall out. But unexpected events might mean teeth overstay their welcome or depart too soon. When the Tooth Fairy can’t keep to her schedule, schedule an appointment at Dallas Dental Arts in Dallas as soon as possible to make sure your child is on track for a future of healthy smiles.
