Brushing Mistakes You Don’t Know You’re Making

October 29th, 2025

It’s great that you’re enthusiastic about your dental health! Here are some tips from Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team to make sure you are getting the most out of your brushing by avoiding common mistakes.

Choose the right brush

In almost every case, a soft brush provides the right amount of bristle-strength to clean your teeth and gums effectively. Hard bristles can damage sensitive enamel and gum tissue, so treat yourself kindly. Also, choose a brush head that’s the right size for your mouth, since a toothbrush that’s too large can be uncomfortable and unable to reach all the areas you need to brush.

Don’t keep your brush too long

Three months is about the average life of a toothbrush. Over time, bristles become frayed or worn and lose their effectiveness. It’s also a good idea to replace your brush after an illness.

Be gentle

Even with a soft brush, it’s possible to brush so hard that your enamel and gums are affected. Think of yourself as massaging your teeth and gums rather than scrubbing them.

Use proper technique

Using a “sawing” back-and-forth motion is hard on your enamel and misses plaque and debris between the teeth. Hold your toothbrush at a 45-degree angle, especially at the gumline, to gently remove plaque. Use short strokes or a circular motion to clean as much of the surface and between the teeth as possible. Make sure you cover all the surfaces of your teeth: outside, inside, and chewing. And don’t forget your tongue!

Take your time

Brushing twice a day for two minutes each time is the standard. Most people brush much less; try using the stopwatch on your phone or a two-minute timer to make sure you are spending enough time brushing. On the other hand, if you brush too hard or too often, remember that over-brushing can lead to problems for your gums and enamel.

Your daily routine might be fast and furious, but your dental routine requires a gentle, methodical approach. Ask at your next visit to our Dallas office, and we will be happy to help you design the perfect brushing practices for your busy life.

Dental X-Rays: Are They Safe?

October 22nd, 2025

X-rays have been a function of dental healthcare for a long time. That in and of itself should be good news, because it means we've had plenty of time to improve them. While there is always some risk in exposure to radiation, dental X-ray exposure has decreased significantly due to all the advances in technology. So there’s risk, but X-rays are quite safe.

Think of X-rays as you would about a car. Automobiles these days have all kinds of technology to make them as safe as possible. There's still a chance that you’ll suffer an accident. Would you stop using a car because of that risk? When it comes to dental X-rays, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team believe the positives clearly outweigh the negatives.

X-rays can be done digitally or with film. For film, X-rays require different exposures at different speeds to produce the image. Digital X-rays have software that automatically adjusts the exposure and produces the X-ray in a digital file. Since they substantially reduce your exposure to radiation, digital X-rays are the current standard in dental offices.

In addition to digital X-rays, lead aprons are an essential piece of X-ray safety. They help protect internal organs from X-rays by acting as a shield. They usually come with a thyroid collar as well, since that is one of the most vulnerable areas to X-rays in the body. Lead aprons can absorb up to 95% of any scatter rays that result from an X-ray. Not bad, right?

Although dental X-rays involve some radiation exposure (not all of it can be eliminated), so does everyday life. Getting too much sun, for example, can be dangerous. The truth is, we accumulate radiation in our bodies over a lifetime, so it’s worthwhile to be aware and avoid as much unnecessary exposure as possible. When it comes to your dental health, though, getting an X-ray — especially when your doctor says you need it — offers more benefits than risks.

Double Duty

October 17th, 2025

If you play a contact sport, you know about mouthguards. You know about the cushioning protection they provide for your teeth. And not just your teeth—mouthguards also help protect your lips, tongue, and jaw, helping you avoid or minimize many of the injuries caused by collisions.

But you don’t have to be part of the defensive line or face off on center ice to wear a mouthguard. It pays to be proactive with your oral health in any activity where impact is a possibility. Whether you play a team sport, practice gymnastics, ride a bike, ski, skateboard, or participate in other athletic pastimes, there’s almost always the risk of impact—with a ball, with the mat, with the sidewalk, with another person.

So, how do mouthguards protect your teeth and mouth? It’s a combination of materials and design. Mouthguards are made of a strong, cushioning material such as plastic or silicone, which helps absorb and distribute the force of impact, usually in the form of a horseshoe-shaped piece that fits over your upper teeth. The specific design can be tailored to the sport or activity you’ll be using it for.

And now that you’re wearing braces? Working toward an attractive, healthy smile doesn’t mean you can’t be active or find a mouthguard that will work for you. In fact, when you wear braces, mouthguards do double duty—they protect your mouth and teeth, and they protect your braces, too!

Even minor impacts can damage wires and brackets, and damaged braces means more time at the orthodontist and lost treatment time. More important, your guard not only helps protect your brackets and wires from impact injury, it protects your delicate mouth tissue from trauma caused by impact with your brackets and wires.

Because you probably have braces on both upper and lower teeth, the usual mouthguard design might not work for you. To make sure you’re completely protected, you may need a guard that covers both upper and lower arches.

There are over-the-counter mouth guards designed for braces, and even for covering both your upper and lower teeth. These might be one-size-fits-all or fit-it-yourself guards, or models which should be used only after a fitting at our Dallas dental. While some of these guards are better than others, the best option for your teeth—and your braces—might be a custom mouthguard.

What are the benefits of a custom guard for orthodontic patients? They:

  • Provide a perfect fit around teeth and braces
  • Protect better because they fit better
  • Are designed for easy breathing and speaking
  • Are less bulky
  • Are more durable
  • Fit more comfortably
  • Can accommodate orthodontic adjustments
  • Can be tailored to your specific sport or activity.

Custom mouthguards are more expensive, because they are individually crafted for your teeth and braces, but in terms of effectiveness, they are the best guards out there—because they are individually crafted for your teeth and braces. If cost is an issue, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani can let you know whether an over-the-counter option might work for you.

An active life should mean proactive dental care. Wearing a mouthguard when you’re wearing braces protects both your body and your orthodontics. Whichever guard option you choose, it’s a good idea to check out the fit with Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani to make sure you’re getting all the protection you need for both when your mouthguard is doing double duty.

Why Baby Teeth Matter

October 17th, 2025

Sleepless nights, crankiness, drooling—how can such tiny teeth cause such a big fuss? But all those uncomfortable days and nights are forgotten when your baby’s first teeth make their appearance. Why? Well, certainly because your child is happier, but also because you know baby teeth, or primary teeth, are important for your child’s growth in so many different ways.

  • Chewing and Eating

Your baby might enjoy solid foods at an early age, but real chewing doesn’t happen until all the baby molars appear between the ages of one to three years. This is the time to feed children size-appropriate and texture-appropriate foods so they acquire proper chewing and eating habits for healthy digestion. Chewing also helps develop your child’s jaw and facial muscles.

  • Developing Speech

Pronouncing many of the common sounds used in speech often requires tongue and teeth working together. If teeth are missing or there is a bite problem such as an open bite, it might be more difficult to pronounce words properly. This could be only a temporary delay, or it could require speech therapy when your child is older.

  • Setting the Stage for Permanent Teeth

Baby teeth not only help with speech and jaw development, but they serve as space holders for permanent teeth. If a primary tooth is lost too early, a permanent tooth might “drift” into the empty space. The adult tooth will not have the room to fit where it should, and crowding or misalignment can occur. This might cause orthodontic problems in the future.

  • Learning Healthy Dental Habits

You are your baby’s first dental health care provider! Wiping the gums and erupting teeth with a soft damp cloth after meals, gently brushing baby teeth when your toddler is young, teaching how to brush as your child gets older, helping to establish daily routines for brushing—all these practices will prepare your child for lifelong healthy dental habits.

  • Making the Dentist a Regular Part of Your Child’s Life

Your child should visit our Dallas office soon after that first tooth comes in, and definitely by the age of 12 months. Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani can help with suggestions for your brushing and flossing routine, make sure your child’s teeth are healthy and clean, and ensure that teething progress is on track. In later visits, we will examine your child’s primary teeth and gums, and treat any problems, such as cavities, before they can become serious.

It turns out that baby teeth really are a big deal. Talk to us about suggestions for caring for your toddler’s teeth and about any questions you may have about teething progress, jaw and facial structure, speech development, or any other concerns at any time. We want to have a happy relationship with your child from the very start for a lifetime of healthy and confident smiles.
