Shark Teeth

July 9th, 2025

It seems like sharks are everywhere these days—on land, sea, and air(waves). A halftime show meme gone viral. A week of summer TV devoted to our favorite apex predators. And who doesn’t have “Baby Shark” playing in their heads all day once they’ve heard it? But are we jumping the shark to discuss this topic in a dental blog?

Not at all! Because today, we’re going to talk about shark teeth—just not the ones you might be expecting.

One of the expected sights when a shark opens its mouth are those rows and rows of shiny shark teeth. Sharks can grow from two to 15 rows of teeth at any one time (and some sharks have even more). This means sharp new teeth are always ready to replace any shark tooth which is lost, broken, or worn out.

An unexpected sight? When children point to their new adult tooth or teeth coming in—right behind their still-firmly rooted baby teeth! This double set of teeth is called “shark teeth,” and, while it certainly might come as a surprise, it’s not all that uncommon. But why do children develop shark teeth at all?

After all, baby, or primary, teeth have small roots, and are designed to come out easily when the adult teeth start arriving. When a permanent tooth starts to erupt, it pushes against the root of the baby tooth above it. This pressure gradually dissolves the root of the primary tooth, and with nothing to anchor it, it’s now loose, wiggly, and ready to fall out. That’s why baby teeth often look like they have no roots at all when they eventually wiggle free.

Sometimes, though, the roots of a primary tooth don’t break down, which means baby teeth stay right where they are. It also means that the permanent teeth have to erupt somewhere else—usually behind those stubborn little baby teeth.

Shark teeth can first appear around the ages of five to seven when the permanent front teeth start arriving, or several years later, when the adult molars begin to come in. Any extra teeth in one small jaw naturally cause concerns about crowding and misalignment, especially when those extra teeth are molars. Fortunately, treatment is generally uncomplicated.

If the baby tooth is loose, time (and wiggling) might take care of the problem. But if the primary tooth or teeth just won’t budge, even after several weeks, it’s a good idea to schedule a visit with Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani—especially if your child is experiencing pain or discomfort.

An extraction is often suggested when a baby tooth has overstayed its welcome. Because of its smaller root, extracting a primary tooth is usually a straightforward procedure. Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani can let you know all the details, and can discuss sedation options if they’re appropriate for your child.

Whether baby teeth are left to fall out on their own, or given some assistance, most often your child’s permanent tooth will start moving to its proper position as soon as the space is available.

Unlike sharks, we don’t have an endless supply of replacement teeth, so it’s understandable to worry when you see anything unexpected. If you want to know more about shark teeth, or if you have any concerns, don’t hesitate to call our Dallas office for expert advice.

Celebrate the Fourth with a Smile!

July 2nd, 2025

As our nation prepares to observe its birthday, we’d like to share some timely dental tips to help make celebrating the Fourth of July more enjoyable for you and healthier for your teeth and gums.

Hydrate

It might be hot and humid where you’re living, so be sure to keep hydrated in the backyard or along the parade route. Proper hydration is essential for both your overall health and your oral health. Drinking water helps prevent cavities by washing away food particles and bacteria and reducing acidic conditions in the mouth. 

Use Ice for Cooling, not Chewing

If you’re enjoying an icy cold beverage to beat the heat, don’t crunch down on that ice! Chewing on ice can lead to immediate disaster in the form of a chipped or cracked tooth or a broken filling or crown. And, over time, munching ice will damage your enamel, making your teeth more sensitive to heat and cold and more vulnerable to cavities. 

Enjoy All Your Cookout Favorites

If you celebrate the Fourth with family and friends, there’s a good chance you’re celebrating outdoors. According to surveys, Independence Day is the most popular grilling day in the country. Are you sitting on the picnic table sidelines because of loose teeth, tooth pain, or missing teeth? Don’t miss out on any of the fun in Dallas! 

  • Tooth pain can be caused by cavities. It can also be a sign of a damaged tooth or an infection. If you suffer persistent tooth pain lasting several days or more, it’s time for a dental appointment.
  • Gum disease can cause bone loss, loose teeth, and lost teeth, making sharing a meal with friends something you avoid instead of something you look forward to. Regular flossing, cleanings, and checkups will help keep your gums in the pink. If you have advanced gum disease, we can discuss treatment options.
  • If you or a loved one wear braces, be sure your BBQ choices are not only delicious, but safe for wires and brackets. Offer menu options which are braces-friendly—that is, which are soft and easy to eat rather than hard, crunchy, or sticky. Remove kernels from corn on the cob and have utensils available to cut finger foods like burgers and hot dogs into fork-friendly bits. 
  • Missing teeth not only make dining difficult, but can also lead to gum disease, decay, and misalignment in adjacent teeth. To enable you to enjoy your meals and to protect your dental health, talk to Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani about implants, bridges, or dentures to make your smile complete again.

Whether you’re marching in the parade, enjoying a meal with family and friends, oohing and aahing at the fireworks, or all of the above, we wish you a healthy and happy Fourth of July! If you have any dental concerns, we’re here at Dallas Dental Arts to help you achieve your best smile every day of the year.

Seal of Approval

June 25th, 2025

Outside activities? You slather your kids with sunscreen. Biking? You don’t let your child leave the house without a helmet. Youth sports? You provide mouthguards and padding and headgear and all the other tools designed to keep your child safe. Protecting your child is a fundamental part of parenthood, and you take your job seriously.

Protecting your child’s dental health is fundamental, too! Tooth decay is the most common chronic disease in children, and children’s premolars and molars are far more vulnerable to decay than any of their other teeth. You can help protect your child’s molars and premolars with a simple and effective treatment—dental sealants.

  • How Do Sealants Work?

The bacteria in plaque use food particles to create acids. These acids erode the minerals in tooth enamel, creating weak spots that become cavities over time. Molars and premolars are especially vulnerable to cavities because of their uneven chewing surfaces. The dips and grooves on top of the teeth—technically known as “pits and fissures”—collect food particles and bacteria, and can be difficult for children to clean completely when brushing. That’s why cavities are so common in newly erupted molars.

Dental sealants protect your child’s molars and premolars by creating a barrier that covers and smooths out the chewing surface of the tooth, preventing bacteria and food particles from getting stuck inside those uneven pits and fissures.

  • What Kind of Sealants Are Available?

The two most common dental sealants are composite resin coatings and glass ionomer sealants.

With resin sealants, after each tooth is cleaned and dried, an etching solution will be brushed onto the top surface of the molar. This etching slightly roughens the surface so that the sealant will stick to the tooth more effectively. A thin coat of the sealant is then painted on and hardened under a special curing light.

Glass ionomer sealants use a flexible paste that bonds to the tooth and hardens within minutes. While they generally don’t last as long as resin sealants, they are designed to absorb and release fluoride for extra cavity-fighting protection.

  • Do Sealants Work?

They certainly do! According to the Centers for Disease Control, sealants can prevent 80% of the cavities in molars and premolars, which is where 90% of children’s cavities appear. Dental sealants can last from three to five years, or even longer. Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani will check the condition of any sealants at each dental exam, and let you know if it’s time for a reapplication.

  • When’s the Best Time to Get Sealants?

Tooth enamel gets harder as we get older, so children’s newly erupted teeth are more at risk for cavities. First adult molars usually arrive when a child is six to seven years old, and second adult molars come in around the age of 12. The first and second premolars can erupt between the ages of ten to 12. As soon as the first permanent molars begin to erupt, it’s a good time to talk to Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani about the best time to apply sealants.

And what about baby teeth? Even though baby teeth are meant to be replaced, they shouldn’t be lost to tooth decay before they are ready to fall out. Primary teeth help young children learn to speak and eat properly and hold the place for adult teeth so these permanent teeth come in where they should. Baby teeth have thinner enamel, and so cavities can progress more quickly. Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani can let you know if sealant protection for your child’s baby molars is indicated.

Applying sealants at our Dallas office is a safe, simple, cost-effective, and painless process. Dental sealants are one more tool you can use to make protecting your child’s dental health a little easier and a lot more effective. That gets a well-deserved parents’ seal of approval!

What is a crown?

June 18th, 2025

If you have never had a crown before, you might be wondering why crown treatment is best, what the procedure involves, and which type of crown to choose. Let’s get down to the basics of crowns!

A crown is the best way to treat many dental conditions, either to strengthen and save the tooth or to improve its appearance. We might suggest a crown if you have any of the following conditions:

  • A filling that needs to be replaced, without enough tooth structure left to fill properly
  • A tooth that is fractured or broken, or so weak that it might fracture
  • A recent root canal
  • An implant
  • A bridge which needs a crown to serve as the base for attachment
  • A tooth that is discolored or irregularly shaped

On your first visit to our Dallas office, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani will prepare the tooth that will be receiving a crown. A tooth might have to be built up if there isn’t enough of the original tooth left, or the top and sides of the tooth will be shaped down so that the crown fits smoothly and evenly with your other teeth. An impression will be made and sent to a dental lab so that a crown with the perfect fit for your tooth and mouth can be created. A temporary crown will be put in place to protect your tooth while the final crown is fabricated.

 The permanent crown is a cap which covers your tooth. It can be made of various materials, which all offer different advantages:

  • Metal Crowns—made of gold, platinum or base metal alloys, these are the longest lasting. Because of their metallic color, they are often chosen for back molars where they are less visible.
  • Porcelain Over Metal—because the color of the porcelain is matched to your natural teeth, these crowns look very realistic. Porcelain is more fragile than metal, so there is the possibility that they won’t be as durable.
  • Resin—less expensive than other options, but these crowns are more fragile and do not wear as well.
  • All Porcelain/All Ceramic—the most realistic looking option, especially for front teeth, and also suitable for anyone with a metal allergy. They are, again, not as strong as metal crowns, and can be subject to damage.
  • Stainless Steel—often used for baby teeth or as a temporary crown for adult teeth.

We’ll discuss your options and help you decide on the best type of crown for you. When the crown is finished at the dental lab, you will have one more visit where the crown will be secured in place. We will make sure your bite is comfortable and the color and appearance of the crown are satisfactory. We will also give you instructions for the next few days following the procedure, and can make adjustments if needed.

A crown is a perfect example of form and function working together: a crown maintains the beauty of your smile and preserves the health of your tooth. If you need a crown, we will be happy to talk to you about your best options for a strong, long-lasting, and natural smile.
