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. Drs. Hutcheson, Train, Abie, Dyer 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 Richardson or Carrollton orthodontic office, Drs. Hutcheson, Train, Abie, Dyer 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!

Many varieties of fillings are available at our Richardson or Carrollton office. Most people are familiar with traditional amalgam fillings: those big silver spots on top of teeth.

Made from a mixture of silver, tin, zinc, copper, and mercury, amalgam fillings have been used to fill cavities for more than 100 years. They offer several advantages, including:

• High durability for large cavities or cavities on molars
• Quick hardening time for areas that are difficult to keep dry during placement
• Reduced placement time for children and special-needs patients who may have a difficult time keeping still during treatment

Although dental amalgam is a safe and commonly used dental material, you might wonder about its mercury content. You should know that when it’s combined with the other metals, mercury forms a safe, stable material.

The American Dental Association, U.S. Centers for Disease Control and Prevention, U. S. Food and Drug Administration, and World Health Organization all agree that based on extensive scientific evidence, dental amalgam is a safe and effective cavity-filling material.

White Fillings

Newer, mercury-free, resin-based composite fillings (white fillings) are also available at our Richardson or Carrollton office. Composite resin fillings are made from plastic mixed with powdered glass to make them stronger.

Resin-based fillings offer several benefits for patients, including:

• They match the color of teeth
• Less tooth structure needs to be removed than with amalgam fillings
• BPA-free materials can be used

Resin-based composite fillings also have some disadvantages, including:

• Higher cost than amalgam fillings
• Inlays may take more than one visit
• Requires more time to place than amalgam fillings

There’s a lot to think about when you have to get a cavity filled. We recommend you do your homework and speak with Drs. Hutcheson, Train, Abie, Dyer before deciding what’s best for you or your family.

At Children's Dental Specialists, we know orthodontic emergencies are neither convenient nor timely. If you are a patient of record, Drs. Hutcheson, Train, Abie, Dyer and our team are more than willing to see you after hours or over the weekend. As a general rule, you should call our Richardson or Carrollton office when you experience severe pain or when you have a painful appliance problem that you can’t take care of yourself. We’ll be able to schedule an appointment to resolve the problem. If you have an orthodontic emergency after regular office hours, please give us a call and follow the emergency prompts to contact one of our doctors.

You’re biting into something delicious, and, Ouch! You bite into something you didn’t mean to—the inside of your tender cheek.

Painful moments like this happen every now and again. But if you find that more frequent cheek biting means that you’re extra-cautious when eating or speaking, if you wake up with sore cheeks in the morning, or if you catch yourself gnawing on your cheeks during the day, it’s time to see Drs. Hutcheson, Train, Abie, Dyer.

Causes of Cheek Biting

Many of us experience the occasional cheek chomp when we’re eating or talking. No fun! Besides the pain, a bite can cause broken skin, inflammation, a canker sore, or a cyst. Luckily, the discomfort from these accidental bites generally resolves after a few days.

Sometimes, though, biting becomes a more frequent annoyance. Regular bites can be caused by several conditions. One of the most common?

• Orthodontic Misalignment

If you notice that you seem to be biting your cheek a lot when eating or speaking, it could be an orthodontic problem. When your teeth or jaws don’t align properly, if your mouth is small in proportion to your teeth, or if your teeth have shifted over time, your cheeks can feel the consequences! Drs. Hutcheson, Train, Abie, Dyer can help you discover if a misaligned bite is the source of your biting problems.

But it’s not just orthodontic problems which can cause painful cheek bites. Other causes can include:

• Bruxism

Bruxism is a medical term for tooth grinding. If you clench or grind your teeth as you sleep, it’s hard on your teeth and on your jaws. And for some people, that nightly gnashing causes cheek biting as well.

• Wisdom Teeth

Most of us don’t have the room to welcome four new—and large—teeth. As the wisdom teeth come in, they can cause bites, especially if they erupt leaning outward toward your cheeks. They can also push your other teeth out of place.

Treatment Options

Why visit our Richardson or Carrollton orthodontic office? A one-time bite can be extremely uncomfortable, and might lead to inflammation or a sore spot inside your mouth. Usually, these reactions fade in a short while.

But what about continuous biting? Regular biting injuries can lead to bigger problems. Tissue can get thicker or erode. Scar tissue can build up inside the mouth. Ulcers and other sores can become larger and more painful.

If you’ve been biting your cheeks more often, your orthodontist can diagnose the cause and offer you treatment options depending on the reason for this frequent biting:

• Orthodontic Treatment

Orthodontic treatment can improve tooth and bite alignment—and can eliminate those painful cheek bites if misalignment is what’s causing them. Today’s orthodontics offers more options than ever before, for both adults and kids.

• Traditional braces are more effective—and more subtle—than ever, with brackets which are smaller or come in clear and ceramic styles.
• Clear aligners are a convenient, almost invisible way to treat misalignment with a series of trays which gradually improve alignment with each new set.
• Lingual braces are attached to the back of the teeth, so there are no visible brackets and wires.
• Functional appliances can improve and correct bite issues which braces or aligners alone can’t treat as effectively.

Whatever the reason for painful cheek biting, you deserve to eat and speak and enjoy your day without constant “Ouch!” moments affecting your comfort and health. If these moments are happening all too often, visit our Richardson or Carrollton office for the answers to your biting problems.
