The words “overbite” and “overjet” certainly sound similar. Both conditions concern your front teeth. Both conditions fall under the same category of bite problems—Class II malocclusions, if you want to be technical. So it’s not surprising that they’re often used interchangeably. But while there are similarities, overbite and overjet are also distinctly different.

• Overbite/Overjet Geometry

In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. The key word here is “slightly.” With a Class II malocclusion, the upper front teeth project further beyond the lower teeth than they should.

Of course, teeth and bites are as individual as we are, so there are variations in just how and just how much the overlap occurs. In diagnosing an overbite vs. an overjet, the difference comes down to a matter of vertical vs. horizontal.

An overbite, or deep bite, occurs when the top teeth vertically overlap the bottom teeth more than they should for a healthy bite. Generally, when a person’s top teeth cover more than a quarter of the bottom teeth when biting down, or more than two to three millimeters, that person is said to have an overbite.

An overjet, commonly known as protruding or buck teeth, is the result of a horizontal overlap that is broader than normal. This causes the top teeth to project outward toward the lips more than they do in a typical bite. An overjet is usually diagnosed when the horizontal distance between the top and bottom teeth exceeds two to three millimeters.

• Overbite/Overjet Causes

The causes for both an overbite and an overjet might be dental (caused by tooth alignment), or skeletal (caused by bone development), or a combination of both. These bite problems can run in families. They are also affected by the size and position of the jaws and the shape and position of the teeth.

Early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use, can also contribute to the development of a Class II malocclusion, particularly an overjet. Consistent pressure from thump or pacifier pushes the teeth outward as they erupt, which encourages them to protrude. These oral habits can affect the shape of the palate and jaw, too.

• Overbite/Overjet Treatments

There are many types of treatment available to correct teeth and bite misalignments. Dr. Sanjay Kuruvadi will tailor your treatment to your specific malocclusion for the best orthodontic outcome.

If you have a mild malocclusion, and minor dental issues are the main cause of that malocclusion, either braces or clear aligners can be effective for an overjet or an overbite. Elastics (rubber bands) are often used as part of this treatment.

If the malocclusion is due to bite problems caused by uneven upper and lower jaw development, devices called functional appliances can be used with braces to help guide the growth of the jawbones while young patients’ bones are still forming. These include appliances that work inside the mouth to help the upper and lower jaws grow proportionally, and external appliances such as headgear.

In some cases, where the malocclusion is skeletal in nature as well as dental, surgical treatment might be necessary to reshape the jawbone itself. Orthodontic treatment is usually needed as well both before and after surgery.

• Overbite/Overjet Consequences

Over time, a deep overbite can cause damaged gum tissue, worn enamel, and fractured teeth. When teeth protrude because of an overjet, they can lead to self-consciousness and are more at risk for injury. Both malocclusions share dental and medical consequences, including concerns about facial and jaw appearance, problems speaking or chewing, headaches, and face and jaw pain.

Class II malocclusions aren’t all the same, and orthodontic patients aren’t all the same either. You may have a minor malocclusion or a significant one. You may have an overbite, or an overjet, or a combination of different bite and alignment concerns. Your malocclusion may not bother you at all, or it may cause pain, discomfort, or self-consciousness.

That’s why every overbite or overjet should be evaluated by an orthodontist. When you visit our Chula Vista or El Cajon, CA orthodontic office, Dr. Sanjay Kuruvadi will be able to diagnose the exact nature of your malocclusion, the reason for it, and your best individualized treatment plan. An overbite and an overjet are different malocclusions, but you and your orthodontist want the same outcome for each: a healthy, attractive, and confident smile!

The alarm sounds in the morning, you wake up and realize "I forgot to wear my retainer!"

If this only happened once, don't panic. Missing one night with a retainer is unlikely to cause significant teeth movement. However, if it has happened often, give our Chula Vista or El Cajon, CA office a call to make sure your teeth haven’t shifted position.

Here are some tips from Dr. Sanjay Kuruvadi to help you remember your retainer:

1. Write down the instructions we give you for wearing the retainer, whether you should wear it all day or at night, or just a few times a week. Writing things out like this helps set the schedule in your memory.

2. Clean the retainer when you take it out each time. If you don’t you may not have time when you’re rushing to get to work or school to clean it properly and may be tempted not to wear it.

3. Put a note on your mirror or in your purse or wallet reminding you to wear your retainer.

4. Set an alarm on your mobile phone to remind you when it’s time to put the retainer in. If you have email with a calendar you can set up daily reminders, too.

5. Always put the retainer in its case when you take it out to eat or sleep. You’ll reduce your risk for losing it or accidentally throwing it away.

6. If you don’t have to wear the retainer every day, you can use some recurring events to help you remember. With this system for example, watching your favorite weekly TV show, laundry day, or family pizza night can all serve as reminders that you should put in your retainer.

7. Don’t be shy about asking for help if you’re forgetful. Assure your spouse, parents, siblings, or roommates that you won’t consider if nagging if they remind you to wear your retainer.

8. Surf online for examples of how teeth can shift when retainers are not properly used. Those stories can serve as timely warning not to let the same thing happen to you!

Remember, you can always call our Chula Vista or El Cajon, CA office if you feel your retainer is uncomfortable or painful. We'll work with you to protect your smile!

Even though it’s called a “permanent retainer,” your fixed retainer isn’t necessarily meant to last a lifetime. But with care, it should last just as long as you need it, keeping your teeth perfectly aligned after your orthodontic treatment is complete. Why is this retainer the one to choose for challenging alignments?

A fixed retainer is often used for teeth which were very crowded or had large gaps before treatment, especially along the bottom teeth, which tend to shift more. With a permanent retainer, a custom fitted wire is attached with a bonding adhesive to the back of each of the selected teeth. This design makes sure that the teeth can’t shift out of place while your bones and ligaments strengthen around them.

Occasionally, though, your permanent retainer isn’t quite as permanent as it should be. If you think your fixed retainer is becoming “unfixed,” what clues should you look for?

• Broken wire

A clearly broken wire can be obvious, or you might discover it when you notice pain or irritation caused by the end of a wire poking around your tongue or mouth.

• Loose bond

The orthodontic adhesive used to bond the wire to each tooth can come loose as the result of an accident, an unfortunately chewy treat, or simply with the passage of time.

• Shifting teeth

You might not notice anything wrong with your retainer, but what you do notice is that your once-straight teeth have started shifting back to their old positions. If you see any movement in your teeth, your retainer might need repair.

What should you do?

• Give our Chula Vista or El Cajon, CA orthodontic office a call! It’s important to act promptly to prevent further retainer damage, oral discomfort, and tooth misalignment.
• Rinse with warm water if your mouth is irritated.
• If a wire is poking you, call us for advice on gently pushing it back into place.
• Orthodontic wax can protect your teeth and tissue from detached wires.
• If you have a clear retainer, wear it until you can come in. If you don’t have one, and you can’t see us immediately, ask if an over the counter moldable retainer is a good idea to help keep your teeth aligned in the meantime.

One benefit of a fixed retainer is that it’s almost invisible because it’s behind your teeth. But this hidden location can also make it difficult to notice potential problems. Fortunately, there are some proactive steps you can take to help your permanent retainer—and your bite—stay healthy:

• Avoid foods which are sticky, hard, or chewy. If a food can damage traditional braces, it can damage your retainer.
• Wear protective gear like mouthguards and helmets when you’re active—they protect more than just your retainer!
• Ask your dentist to examine your retainer adhesive’s staying power whenever you have a checkup.

If you notice a detached wire or loose adhesive or see your teeth shifting, give Dr. Sanjay Kuruvadi a call. It’s important to act promptly to fix a fixed retainer, because your teeth and bite alignment are in jeopardy when you delay. And always bring your retainer (or retainer pieces) with you in case we can repair it.

Permanent retainers don’t necessarily last forever. But whether your fixed retainer is going to be with you long-term, or whether you’re going to transition to a removable retainer in the future, let’s make sure your permanent retainer is just as “permanent” as it needs to be!

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. Sanjay Kuruvadi 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. Sanjay Kuruvadi 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 Chula Vista or El Cajon, CA office and a smile that will last you for a lifetime. Those are benefits we can talk about all day!
