Kristin Cavallari and Palatal Expanders

April 30th, 2025

It’s no easy feat to have one of the best smiles in Hollywood. The reality TV starlet Kristin Cavallari attributes her gorgeous smile to routine oral hygiene, the removal of two impacted wisdom teeth, and having undergone orthodontic treatment. Kristin’s treatment began in sixth grade when she was fitted with a device Dr. Perry and our team call a palatal expander, which is used to guide upper jaw growth in our younger patients.

What is a palatal expander?

A palatal expander “expands” (or widens) your upper jaw by applying gentle pressure on your upper molars, and is used to make the bottom and upper teeth fit together better. In addition, palatal expanders work to create more room for teeth, as well as promote a broader, more appealing smile.

Do palatal expanders hurt?

Palatal expanders are usually not painful, however you may experience difficulty speaking and swallowing for the first few days. Adjusting your palatal expander as instructed by Dr. Perry will ensure there are no delays in regards to your treatment plan.

Typically, it takes a few weeks to achieve the desired amount of expansion, after which you will keep wearing your expander for about six months, giving time for the new bone to form and stabilize. Dr. Perry and our team at Robert H. Perry Specialist in Orthodontics will give you detailed instructions about how to adjust your appliance and can answer any questions you may have about your palatal expander.

If you have any questions about your palatal expander or your treatment plan with Dr. Perry, please give us a call at our Corinth, MS office!

Orthodontic Myths

April 23rd, 2025

Some myths never wear out their welcome. If the Tooth Fairy helps your child transition from baby teeth to adult teeth, more power to her! On the other hand, some myths we can do without. Here are five common misconceptions about orthodontics, and the reality behind the myth.

  • It’s Only Cosmetic

If you think orthodontists can make a crooked smile straight, you’re right! Creating a beautifully aligned smile is one of our specialties. And if your primary interest is in a straight, even smile for you or your child, that’s a good thing. You can’t underestimate the confidence a beautiful smile brings. But please don’t think that’s all we do. In orthodontics, aesthetics and function work together. An essential part of an orthodontist’s work is diagnosing and treating malocclusions, or bad bites. The correct alignment of teeth and jaw is what makes a beautiful smile a healthy one as well.

  • I Don’t Need an Orthodontist for Orthodontic Treatment

All dentists receive comprehensive training and experience in order to earn their dental degrees. But did you know orthodontists like Dr. Perry receive two to three years of additional formal training, concentrating specifically in the field of orthodontics? An orthodontist is a specialist, and diagnoses and treats problems with tooth alignment while taking into account dental, jaw and facial development. That is why an orthodontic specialist is best qualified to create a unique, custom-tailored treatment plan for each patient in order to achieve a beautiful, balanced, and healthy smile.

  • My Child is Too Young for Orthodontic Treatment

We actually recommend that every child see an orthodontist for an evaluation by the age of seven. It’s important to be aware of any potential orthodontic problems that might affect your child’s later years, but we can also treat problems even before braces are on the horizon. If your child’s mouth is very small, we may recommend gently enlarging the upper dental arch with the use of a palatal expander to accommodate adult teeth as they erupt. If a baby tooth is lost too soon, we can provide a space maintainer so your child’s permanent tooth can erupt in the right place. We can even treat bite problems before all the adult teeth arrive. A visit when your child is young might help prevent the need for more complicated treatment in the future.

  • I’m Too Old for Orthodontic Treatment

You’re really not. As long as your teeth and gums are healthy, orthodontic treatment is a great way to keep them healthy. Crowded teeth and malocclusions can lead to problems like worn or cracked enamel, headaches, jaw problems, increased tooth decay, and periodontal disease, to name but a few. And today’s orthodontics offer a much wider variety of treatment options than the metal gear you remember from your high school days. Which leads us to our last myth of the day:

  • Those Metal Braces Aren’t for Me

In that case, it’s a good thing we have many other options to offer. Ceramic brackets and clear elastic ligatures make traditional braces much less visible. Lingual braces use brackets and wires placed behind the teeth, which are almost impossible to detect. And clear aligners allow you to subtly reposition your teeth with each new aligner tray—and are removable if need be. In fact, even those metal braces you might remember from your own high school days have gotten smaller and sleeker. Talk to us about the many discreet options available for older and younger patients.

If you are interested in what orthodontics might do for you, give our Corinth, MS office a call! We are here to help you discover what’s possible and then to design the best possible treatment plan in order to achieve it.  Let’s make your beautiful, healthy smile a reality!

Things You Should Never Use Your Braces For

April 16th, 2025

When you get your braces, Dr. Perry and our staff will also give you a list of foods you should not eat and things you should not do. Pay particular attention to these items to keep your teeth and braces safe.

Charms belong on bracelets. While you can decorate your braces with colored bands, hanging a charm off them is a bad idea. If you bite down on the charm, you could damage your braces or your teeth. You could also swallow your jewelry.

Never use your teeth as a bottle opener. This is just as important when you are wearing braces. While braces straighten your teeth, your teeth are moving in the process. That makes them weaker, and the metal in the braces does not make them invincible. Invest in a bottle opener; you can buy one for a few dollars, which is much less expensive than having to replace your braces.

Contrary to what you might think, your braces are not designed to work as a radio. There are tales of people who have picked up radio signals from dental fillings or braces. While this is remotely possible, attaching an antenna to your mouth is just not a good idea. You will get better quality music from a radio.

On the other hand, you can still kiss someone while wearing braces. In fact, even if both of you wear braces, the chances of your getting locked together are almost negligible. However, to avoid cutting your partner’s lips, kiss with caution.

If you have any questions about taking care of your braces, please ask Dr. Perry and our staff. We want you to get the best results from your treatment without needless delays.

Crushing the Ice-Chewing Habit

April 9th, 2025

It's a habit many people have and not only can it be annoying to the people around you, it can be detrimental to your dental health. Chewing ice is so common that it even has its own name, pagophagia. We're not talking about a slushy or shaved ice (although those artificially sugary treats should be avoided too!) but more like the hunks of ice rattling around in the bottom of your glass.

Ice chewing can be a sign of emotional problems like stress or obsessive-compulsive disorder, but it can also be a marker for iron deficiency anemia and other physical problems. Then again, some people just like to have something to chew on. For whatever reason you find yourself chewing on it, it's a habit you need to break.

Chewing on ice can cause:

  • Chipped and cracked teeth
  • Damaged enamel
  • Sore jaw muscles
  • Damage to dental work such as crowns, fillings, or other appliances

If chewing on ice is becoming a problem in your life, don’t hesitate to speak with Dr. Perry about it. But if you find yourself still wanting to chew on something, here are a few alternatives to ice:

  • Baby carrots
  • Celery sticks
  • Sugar-free (xylitol) gum

We know you need to chill sometimes, but chomping down your entire glass of ice is not the way to do it. If you have any other questions on the topic, feel free to talk with a member of our Corinth, MS team. It may be beneficial in solving the issue and helping to remediate any damage to your teeth.
