What role do elastics (rubber bands) play in orthodontics?

March 26th, 2025

Wearing orthodontic braces may be the best choice for correcting your teeth and improving your smile, and that's why you've come to see Dr. Perry at Robert H. Perry Specialist in Orthodontics. Braces, which consist of brackets and wires, work by gently applying pressure to the teeth, and that pressure causes them to move into the correct position. In some cases elastics, or rubber bands, are used to apply additional pressure needed to move your teeth.

The Purpose of Elastics

Customized for each patient, the rubber bands typically stretch over tiny loops on the top and bottom brackets. If worn consistently, and every day, these tiny elastics will apply the steady pressure needed to guide your teeth into the correct position.

These elastics are crafted from medical-grade latex, which is safe to be in contact with your mouth. It's common to remove the elastics during meals if opening your mouth wide enough to eat is difficult. Our staff will demonstrate how to affix the elastics so it will soon become second nature to replace them.

The Do’s and the Don'ts

DO - Get in the habit of carrying around extra rubber bands and replace them as soon as one breaks. By consistently wearing the elastics, you may shorten the overall time needed to wear braces.

DON'T - Double up on elastics as this will cause too much pressure on the tooth or teeth and can actually harm the root of the tooth.

DO - Always wash your hands before removing or replacing the rubber bands.

DON'T - Overstretch the rubber band or it will lose its strength and it will be ineffective.

DO - Call us if you run out of rubber bands.

DO - Have fun with your braces and elastics. There are many different colors available that can let you show off your soon-to-be perfect smile.

Rubber bands are a key part of your orthodontic treatment, and learning how to remove and replace them is an important part to maintaining your braces. Before we set you on your journey to a perfect smile, we'll make sure you understand all there is to know about how to take care of your braces. Of course, if you have any questions about your orthodontic treatment, or orthodontics in general, be sure to contact our Corinth, MS office, and our staff will be happy to assist you!

Common Malocclusions

March 19th, 2025

When we think orthodontics, we commonly think teeth. Naturally! Straight teeth and a beaming smile are everyone’s orthodontic goal. But orthodontics is a field which specializes in more than misaligned teeth. While your beautifully aligned teeth are the visible outcome of your orthodontic work, a properly aligned bite is the foundation for your healthy smile.

A malocclusion occurs when the teeth and jaws aren’t properly aligned—they don’t fit together the way they should when the mouth is closed. A malocclusion, or bad bite, affects many people to some degree, but not always in exactly the same way. Some of the different types of malocclusion include:

  • Crossbite

A crossbite occurs when upper teeth fit inside lower teeth. An anterior crossbite refers to the front teeth, with one or more upper front teeth, or incisors, fitting behind lower front teeth. A posterior crossbite affects the back teeth, with upper teeth fitting inside the lower teeth on one or both sides of the jaw.

  • Crowding

When the jaw is small and/or the teeth are large, lack of space can result in crowded, twisted, or crooked teeth.

  • Open bite

An anterior open bite means that the front teeth don’t close when biting down, leaving an open space between the upper and lower teeth. A posterior open bite occurs when the back teeth don’t make contact when the front teeth close.

  • Overbite

Our upper front teeth naturally overlap the lower ones a small bit when the teeth are closed. An overbite occurs when the upper teeth significantly overlap the lower teeth.

  • Overjet

When the upper front teeth protrude too far forward over the bottom teeth, it’s called an overjet, or, sometimes, buck teeth. Where an overbite causes a vertical overlap, an overjet takes into account the horizontal relationship of the teeth.

  • Spacing

A jaw that is large, teeth that are small, missing teeth—these conditions can lead to gaps between the teeth.

  • Underbite

An underbite results when the lower teeth and jaw extend further forward than the upper teeth and jaw, causing the bottom teeth to overlap the top teeth.

If you have a malocclusion, what comes next? This depends.

Some malocclusions are so minor that no treatment is necessary. Some are the result of misaligned teeth. Some occur because the upper and lower jaws are growing at different rates. Some are a combination of teeth and jaw misalignments. Some are caused by genetics, while others are caused by injuries or habits like prolonged thumb sucking or tongue thrusting.

Because malocclusions are so varied, your treatment plan will be designed for your specific needs. Braces, aligners, appliances like the Herbst® appliance or the palatal expander, surgery for severe malocclusions—there is a larger variety of treatment options than ever before to help you achieve a healthy bite.

When teeth and jaws don’t fit together as they should, the consequences can be damaged teeth and enamel, problems with the temporomandibular joint, headaches and facial pain, and difficulty chewing, eating, and speaking.

The good news is that early intervention for children can help correct teeth and jaw problems before they become more serious, leading to easier orthodontic care in the teen years, and helping to avoid the possibility of surgery or extractions. This is why Dr. Perry and our team recommend an orthodontic assessment at our Corinth, MS office for children around the age of seven.

If you’re an adult with concerns about your teeth or bite, there’s good news for you, too. Dr. Perry can devise a treatment plan to improve your bite and your smile no matter what your age.

Of course, despite our title, there’s really no such thing as a “common malocclusion” when we’re talking about your dental health. Each person—and each smile—is unique. Dr. Perry will diagnose your malocclusion and create a personalized plan carefully tailored to your exact needs, for an uncommonly attractive, confident, and healthy smile.

How Long Will My Retainer Last?

March 12th, 2025

You’ve worked hard for your attractive, healthy smile, and now you’re making sure it stays attractive and healthy by wearing your retainer. Since wearing a retainer is usually a matter of years, not months, it’s natural to wonder just how long you can count on that retainer to help you maintain your smile.

That answer depends on the type of retainer you get at our Corinth, MS office. A Hawley retainer, a clear retainer, and a fixed wire retainer have different lifespans. Because they each have their own advantages, Dr. Perry will recommend the retainer that’s right for protecting your individual smile.

So let’s look at the average lifespan for different retainers, and, equally important, some of the common mishaps that can shorten that working life.

The Hawley Retainer

This is the retainer most people picture when they think “retainer.” Made of wire securely attached to an acrylic base, the Hawley retainer keeps the teeth in place, and can even be adjusted, if needed, to improve alignment. They generally last anywhere from three to ten years.

How can you make sure your Hawley retainer keeps working for you as long as possible?

  • Keep it in its case. While some damages to these retainers can be repaired, why take a chance? And it’s much harder to lose a retainer if it’s in its case as opposed to, say, a cafeteria napkin.
  • Keep it away from your pet. Dogs, especially, are tempted by the taste and smell of saliva, but there are safer, less expensive chew toys out there.
  • Keep wearing it. Without your retainer, your teeth can shift. Over time, not only will your retainer fail to fit anymore, but you might need to return for further orthodontic treatment. If you notice your retainer is starting to feel uncomfortable, give your orthodontist a call.

The Clear Retainer

Clear retainers look like clear aligners, and, like clear aligners, are almost invisible. Made of vacuum-formed plastic, they’re designed for a close, comfortable fit, often around the entire arch of your teeth. Also like clear aligners, these retainers aren’t made to last forever. If they become loose, warped, or cracked, they should be replaced. With care, they can last from six months to several years. How to protect them?

  • Protect your retainer from damage. Keep it in its case when you’re not wearing it. You’ll avoid losing it, and you’ll avoid damaging it.
  • Protect it from teeth. And we don’t just mean pets, although they find clear retainers yummy, too. If you grind your teeth, your retainer can suffer. Clear retainers are not the same thing as night guards, so talk to your orthodontist for recommendations.
  • Protect it from heat. Hot surfaces like ovens or heaters, hot dashboards, washers and dryers, even very hot drinks can be a problem. (You should only be drinking water while you wear your clear retainer, so that particular issue shouldn’t arise!)

The Fixed Retainer

A fixed retainer is a small piece of wire that is custom-fit and bonded to the back of specific teeth to prevent any movement from occurring. Because it’s bonded to the inside of the teeth, a fixed retainer is completely invisible when you speak or smile. It can last five years, ten years, and in some cases, even longer. Even though you won’t be exposing this retainer to external dangers like hungry pups or the wash-and-rinse cycle, there are still some situations to watch for:

  • Watch your diet. The same sticky, crunchy, or hard foods that can damage brackets and wires can also loosen a fixed retainer.
  • Watch your dental hygiene. While cleaning around a bonded retainer can be a bit challenging, not cleaning around it can result in plaque and tartar buildup—and your retainer might have to be removed to clean your teeth.
  • Watch for changes. If your teeth start to shift, it could mean your retainer has detached from one or more teeth. Ask your dentist to check the retainer’s bond whenever you have a checkup.

So, how long will that retainer last? Depending on the kind of retainer you have, if you don’t keep it in its case, or if you don’t watch your diet, or if you expose it to heat, the answer is—not nearly long enough. Dr. Perry will give you the very best tips to keep your retainer clean, safe, and working for as long as possible. Now, it’s up to you!

The Best Treats in the House

March 5th, 2025

You waited for this movie all year. You got your tickets early, and you’ve got the best seats in the theater. Whether you paid to see the latest action flick or the most romantic comedy in the history of romcoms, it’s not as nearly as much fun if the trip to the snack bar is a horror story. Perhaps Dr. Perry can help!

If you’re wearing traditional braces, the usual suspects, chewy, sticky, hard, and crunchy foods, are still off limits even when the lights go down. Let’s look at some alternative casting.

  • The Candy Counter

Licorice, caramels, taffy, and candy with nuts can make any film a disaster movie—and can make your next visit to our Corinth, MS office an emergency one. Stick with soft chocolates, chocolates with creamy fillings, ice cream, and ice cream bars (without nuts or caramel, of course).

  • The Soda Fountain

Sodas won’t break your braces, but they will damage your teeth, so try to brush as soon as you can or rinse with water after enjoying one of those titanic servings. And no crunching on ice! That can damage your braces.

  • The Popcorn Machine

Sorry, we can’t help you here. Popcorn, with or without that tempting flood of melted butter, is off limits. The kernels can get lodged between your teeth and braces, and can be very hard to remove. They can also cause breakage to wires and brackets.

If you still crave something salty, check with us to see if soft pretzels or baked potato chips might be an option for you.

Movie treats contain a lot of starches and sugars, which stick to braces and feed cavity-causing bacteria, so it’s always best to go easy on the snacks. But you don’t have to give up the concession counter completely—just enjoy in moderation and be sure to brush thoroughly when you get home.

And if you wear clear aligners? You can remove your aligners, eat what you like, and clean your teeth carefully before replacing them. But do remember—you’re supposed to wear your aligners for a set number of hours each day. If you’re looking forward to a four-hour epic, make sure to take into account your treatment schedule.

We don’t know if your movie was worth the wait. But we do know that the results of your orthodontic treatment will be! Take care of your teeth and braces, and you’ll be on the fastest, healthiest track to an award-winning, red carpet smile.
