What is malocclusion?

March 12th, 2025

The term malocclusion refers to misalignment of teeth. You may have been born with malocclusion, so your teeth simply grew in crooked, or the misalignment and crowding of your teeth occurred over a period of time. Either way, not only can malocclusion pose cosmetic issues, but it can have a negative effect on your speaking and eating abilities as well.

Types of Malocclusion

Malocclusion encompasses multiple types and classifications of misalignment issues, including twisting or rotation of the teeth and molars that do not meet when you bite down. In some cases, the top front teeth are pushed outward in an upper protrusion.

In other cases, a misplaced midline results when the front top teeth don’t meet with the front bottom teeth. Transposition occurs when teeth protrude through the gums in a position where another tooth is supposed to be.

Practically any type of crowding or spacing issues, rotation or twisting of the teeth, or bite problem – including overbite, underbite, open bite, or crossbite – is included under the umbrella of malocclusion.

Malocclusion Classifications

There are three classifications of bite or misalignment problem.

  • Class 1 malocclusion: While the bite may be normal, the upper teeth overlap the lower teeth slightly. This is the most common type.
  • Class 2 malocclusion: Known as overbite or retrognathism, class 2 involves a severe overlap of the upper teeth and jaw over the bottom teeth and jaw.
  • Class 3 malocclusion: Known as underbite or prognathism, class 3 occurs when the lower teeth and jaw overlap the upper teeth and jaw. Thus, the lower jaw juts forward.

Causes of Malocclusion

The most common cause of malocclusion is genetics. However, there may be other causes, including the development of abnormally-shaped teeth, lost teeth, or impacted teeth; thumb sucking or overuse of a pacifier as a small child; having fillings or crowns that do not fit correctly; a serious injury that causes misalignment of the jaw; or developing a tumor of the mouth or jaw.

Treating Malocclusion

Orthodontic care at Davis Orthodontics with Dr. Allen is the main treatment available for malocclusion, which includes getting braces, Invisalign, or other corrective treatments. Treatment is ideal not just to have your smile improved, but because it makes the teeth easier to clean and maintain, lowers the risk of gum disease and tooth decay, and can even take pressure off the jaw and teeth.

Think about orthodontic treatment if you (or your child) display any signs of malocclusion. Early treatment of malocclusion during childhood can lessen expensive treatment later on.

When It Come to Chewing Gum, Be Choosy!

March 5th, 2025

Why do you chew gum? Perhaps because it’s a habit that comes with some healthy benefits. Chewing a stick or two reduces the urge to snack between meals. It’s a substitute for behaviors like nail biting that you’d like to change. It might even give you fresher breath after those tuna sandwiches in the cafeteria.

And, as it happens, chewing sugarless gum actually offers a few dental benefits as well! The act of chewing increases saliva production. Saliva washes away food particles, neutralizes acids in the mouth that can damage enamel, and even bathes the teeth in essential minerals that help strengthen weakened enamel. We’re talking about sugar-free gum here, of course, because regular gum will just bathe your teeth in sugar—no one’s idea of a dental benefit!

So why not open that pack and enjoy? Because, despite the many positive reasons you can think of for chewing gum, sometimes gum can have a negative impact on your braces.

  • A Sticky Situation

Keeping your braces clean can be a bit of a challenge. That’s why you have special toothbrushes, flosses, and interproximal brushes to get rid of food particles that stick around after you eat. And, while any food can get caught in your braces, sugared gum, because it is so sticky, can stick to appliances much more easily and much more thoroughly than even sugar-free gum. You might be able to remove gum residue with regular brushing and flossing, but, worst case scenario, you might be looking at gum firmly stuck in the brackets or between the brackets and wires.

  • Gumming Up the Works

Chewing gum can also affect your treatment time if the action of chewing causes your arch wire to bend. When your wire isn’t providing the proper shape or the right amount of tension, your teeth won’t get to where they need to be as quickly and efficiently. No piece of gum is worth discovering at your next appointment that you haven’t made any progress for weeks due to a damaged wire. And since chewing gum can also lead to loose brackets and bands, you might wonder if this sticky habit is ever worth the trouble it can cause.

  • Something to Chew Over

Before you decide, talk to Dr. Allen! Chewing sugarless gum increases saliva production, which can help wash away food particles from your mouth and your braces. As an added benefit, the action of chewing for a few minutes after an appointment has been shown to reduce the discomfort of an adjustment. Because today’s braces are stronger and more durable, and sugarless gum much less likely to stick to them, we can let you know if chewing gum might be acceptable or even desirable depending on your specific treatment plan and your appliance.

Talk to us at your next appointment at our San Diego office about gum chewing, and we’ll give you the very best recommendations for keeping your teeth healthy, your braces clean, your appliance intact, and your treatment plan on track. Even if gum needs to be off the menu for a while, what you’ll get in return—the best and fastest path to your beautiful smile—will be well worth it!

Your Child’s First Visit to the Orthodontist

February 26th, 2025

We often think of braces as a rite of passage for kids in middle and high school. So you might be surprised when your child’s dentist recommends a visit to see Dr. Allen years earlier than you anticipated. In fact, dentists and orthodontists generally suggest a visit to the orthodontist by age seven at the latest.

Why see an orthodontist so early?

After all, your child is still growing, and many adult teeth haven’t come in at that age. And that’s the whole point.

Around this age, your child will probably have a mix of both baby and adult teeth, so your orthodontist will be able to assess whether there’s enough room for the permanent teeth to erupt without crowding or spacing problems. And malocclusions, or bad bites, caused by problems with jaw size or symmetry can be addressed while young bones are still forming and developing.

If your child has a first appointment coming up on the calendar, here’s a heads up on what often happens during a first visit, and potential problems your orthodontist will be on the lookout for.

What can you expect at a first visit?

The first visit is designed to evaluate how your child’s teeth and jaws work together now, and to look for potential future problems with tooth alignment and jaw structure and development.

First, Dr. Allen will carefully examine your child’s teeth, jaws, and mouth. Your child will be asked to bite down several times to see how the teeth and jaws fit together, and if there’s any discomfort. Other helpful diagnostic tools could include:

  • Scans or X-rays to evaluate jaw structure and the position of teeth which haven’t erupted yet
  • Photos of your child’s teeth and face
  • An impression of your child’s teeth

If there’s no immediate need for treatment, we might recommend periodic checkups at our San Diego orthodontic office to follow the growth and development of your child’s teeth and jaws. If interceptive (early) treatment is your child’s best option for a healthy smile, your orthodontist will explain any immediate orthodontic issues and design a treatment plan tailored to your child’s specific needs.

What are the benefits of early treatment?

Interceptive treatment not only helps correct current orthodontic problems, it can help reduce the need for more complicated treatment in the future, when all of the adult teeth have arrived and bones are fully formed. Among its many benefits, early treatment can:

  • Prevent crowding

If your child has a small upper palate, it can be gently enlarged while the palate is still growing with the help of a palatal expander. This will give the upper teeth the space they need to come in without crowding.

  • Provide space

If primary teeth are lost too early, other teeth can shift out of alignment to fill the empty space. A space maintainer can be custom-made to keep the spot open until the right tooth is ready to erupt. If primary teeth are overstaying their welcome, Dr. Allen might recommend extraction to allow the adult teeth to erupt in the proper place.

  • Create jaw symmetry

Malocclusions can develop because the upper or lower jaw is too narrow, too far forward, too far back, or the jawbones don’t fit together properly. Dr. Allen might suggest the use of a functional appliance such as the Herbst® appliance or headgear to help guide symmetrical bone development while your child’s young bones are still growing and forming.

  • Protect teeth

Children with overjets, or protruding upper teeth, are more likely to suffer chips, cracks, and other trauma to those vulnerable front teeth. Functional appliances can help bring the upper and lower jaws into alignment as needed, and braces can move the teeth into alignment.

Every journey to a healthy smile begins with a first visit. And you don’t need to wait until your child is seven. Any time you’re concerned about an orthodontic issue is a good time for a consultation. Talk to Dr. Allen about what to expect at your first visit to help create a comfortable experience for your child as you begin this journey together.               

Mouthguard Protection

February 19th, 2025

Let’s talk about mouthguards.

We could talk about how important wearing a mouthguard is when you lead an active life. If you play sports, ride bikes, skateboard, or participate in many other kinds of exercise, mouthguards protect your teeth, mouth tissue, and jaws from accidents. 

Or we could talk about how wearing a mouthguard while you’re wearing braces has extra benefits. Besides its normal protection, your guard helps protect your brackets and wires from damaging contact, and your delicate mouth tissue from impact with your braces.

But we’re not going to talk about any of these important topics today. Instead of looking at how your mouthguard protects you, today we’re going to look at how you can protect your mouthguard.

If you want your guard to last longer, work better, and stay (and smell!) cleaner, some basic tips make all the difference.

  • Keep your guard clean.

This can’t be stressed enough. Without a good cleaning routine, your guard can become discolored, develop an unpleasant odor, and even cause illness. Not very appealing, right? Happily, keeping your mouthguard clean isn’t difficult.

When you wear your guard, the same plaque that is present in your mouth makes itself at home in your appliance. And when your guard is in its case, that dark, moist environment makes it a perfect breeding ground for all kinds of bacteria, viruses, and fungi.

As soon as you take your mouthguard out, rinse it off. Brush with a soft toothbrush to remove all the plaque, saliva, or food debris that might be lingering in your appliance. (If you are on the playing field, in the park, or at some other inconvenient location, rinse it and brush as soon as you can.) Toothpaste can help get your guard its cleanest, but can be too abrasive for some appliances.

Once you’ve cleaned it, let your guard air dry in a clean spot for about 30 minutes. Air drying helps prevent bacterial growth. After your guard has dried, return it to its case.

Once a week, you might need to give your mouthguard a good soak in a mouthwash or other dental cleaning solution.

Since cleaning instructions can be different depending on which type of mouthguard you have, be sure to follow our instructions if you have a custom guard, or clean as directed by the manufacturer if you have a store guard.

  • Keep it safe.

When your mouthguard isn’t in your mouth, it should be in its case. Floating loose in your locker or tumbling around in your gym bag puts your guard at risk for breakage and bacteria.

And don’t forget to clean your case thoroughly every few days and air dry it as well. Bacteria, viruses, fungi, mold, and other unwelcome guests can collect in your case, too.

  • Keep it only as long as it’s in good condition.

You can purchase mouthguards from sporting or drug stores, or Dr. Allen can make you a mouthguard designed to fit your teeth and braces perfectly. These appliances are made to be strong and durable, but they’re not indestructible. Over time they can wear down or become damaged, especially if you treat them carelessly.

Bacteria can lurk in dents and cracks, and you can cut your mouth on rough, sharp, or broken edges. But if your mouthguard isn’t fitting properly, don’t resort to self-help! Trying to repair, reshape, or trim your appliance yourself is not a good idea, because it might affect its fit and protective ability.

Any sign that your guard isn’t fitting properly or shows signs of wear and tear could mean it’s time for a replacement. You can replace a store model, or see Dr. Allen about replacing or repairing your custom guard. A mouthguard that doesn’t fit, doesn’t keep you safe.

Take care of your guard, and it will take care of you. The reward for the small amount of time and effort you put into caring for your mouthguard is braces that will last through your treatment at our San Diego office and a smile that will last you for a lifetime. Those are benefits we can talk about all day!
