Bite problems are so common that most of us know someone who’s worn braces. So perhaps you’re already familiar with the terms “overbite” and “underbite”—but if you’ve been diagnosed with an “overjet,” that just might be an orthodontic diagnosis that is new to you. If so, here are a few questions and answers to help promote overjet understanding.

Just what is an “overjet”?

An overjet is a type of malocclusion, which means that there’s a problem with your bite, the way your jaws and teeth fit together when you bite down. In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. The key word here is “slightly.”

An overjet is a Class II malocclusion, which means that the upper front teeth project further beyond the lower teeth than they should. Overjets and overbites are both Class II malocclusions, and the words are often used interchangeably, but there’s a notable difference between the two conditions.

An overbite occurs when the top teeth overlap the bottom teeth too far vertically, and you can’t see as much of the lower teeth as you should when you bite down.

An overjet is considered more horizontal in nature, where the top teeth project at an outward angle toward the lips instead of pointing straight down toward the bottom teeth. This condition is sometimes called protruding or buck teeth.

What causes an overjet?

The reason for your overjet might be dental (caused by tooth alignment), or skeletal (caused by bone development), or a combination of both.

Overjets can run in families. They can also be caused by the size and position of your jaws and the shape and position of your teeth, all of which affect your bite alignment. But early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use, can also contribute to overjet development.

How do we treat an overjet?

There are many types of treatment available. Dr. Kathleen Tavarez will recommend a treatment plan based on the cause and severity of your overjet. Because some treatments are effective while bones are still growing, age plays a part as well.

• Braces and Aligners

If you have a mild overjet, and minor dental issues are the main cause of the malocclusion, braces or clear aligners can effective.

• Functional Appliances

If the overjet is caused by a problem with upper and lower jaw development, devices called functional appliances can be used to help guide the growth of the jawbones while a child’s bones are still forming.

For young patients, there are several appliances which can help correct an overjet. Some, such as the Twin Block and the Forsus Spring appliances, work inside the mouth, while others, like headgear, are worn externally. Your orthodontist will recommend the most effective appliance for your needs.

• Surgical treatment

In some cases, where the malocclusion is skeletal in nature as well as dental, surgical treatment might be necessary to reshape the jawbone itself.

If we recommend surgery, oral and maxillofacial surgeons are experts in surgical procedures designed to create a healthy and symmetrical jaw alignment. Dr. Kathleen Tavarez will work with your surgeon to design a treatment plan, which will usually include braces or other appliances following surgery.

Why treat your overjet?

A serious, moderate, or even mild overjet can lead to many dental and medical problems, including:

• Concerns about facial and dental appearance
• Front teeth which are more at risk for injury
• Difficulty closing the lips
• Problems speaking or chewing
• Headaches, facial, and temporomandibular (jaw) joint pain

When you work with our Menlo Park or San Carlos, CA team to correct your overjet, you’re not just correcting a problem. You’re also creating something—a healthy, comfortable bite, and an attractive, confident smile. We can talk about general answers to your overjet questions, but when it comes to understanding your very individual smile, Dr. Kathleen Tavarez will have all the answers you need to make that healthy bite and that confident smile a reality! 

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. Kathleen Tavarez 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 Menlo Park or San Carlos, CA orthodontic office, Dr. Kathleen Tavarez 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!

It’s a new year, and it couldn’t come fast enough for many of us! Let’s do our part to make this a better year in every way—and you can start by making this the year you quit smoking once and for all.

You know that smoking is very damaging to your body. Smokers are more likely to suffer from lung disease, heart attacks, and strokes. You’re at greater risk for cancer, high blood pressure, blood clots, and blood vessel disorders. With far-reaching consequences like this, it’s no surprise that your oral health suffers when you smoke as well.

How does smoking affect your teeth and mouth?

• Appearance

While this is possibly the least harmful side effect of smoking, it’s a very visible one. Tar and nicotine start staining teeth right away. After months and years of smoking, your teeth can take on an unappealing dark yellow, orange, or brown color. Tobacco staining might require professional whitening treatments because it penetrates the enamel over time.

• Plaque and Tartar

Bacterial plaque and tartar cause cavities and gum disease, and smokers suffer from plaque and tartar buildup more than non-smokers. Tartar, hardened plaque which can only be removed by a dental professional, is especially hard on delicate gum tissue.

• Bad Breath

The chemicals in cigarettes linger on the surfaces of your mouth causing an unpleasant odor, but that’s not the only source of smoker’s breath. Smoking also dries out the mouth, and, without the normal flow of saliva to wash away food particles and bacteria, bad breath results. Another common cause of bad breath? Gum disease—which is also found more frequently among smokers.

• Gum Disease

Smoking has been linked to greater numbers of harmful oral bacteria in the mouth and a greater risk of gingivitis (early gum disease). Periodontitis, or severe gum disease, is much more common among smokers, and can lead to bone and tooth loss. Unsurprisingly, tooth loss is also more common among smokers.  

• Implant Failure

Tooth implants look and function like our original teeth, and are one of the best solutions for tooth loss. While implant failure isn’t common, it does occur significantly more often among smokers. Studies suggest that there are multiple factors at work, which may include a smoker’s bone quality and density, gum tissue affected by constricted blood vessels, and compromised healing.

• Healing Ability

Smoking has been linked to weakened immune systems, so it’s harder to fight off an infection and to heal after injury. Because smoking affects the immune system’s response to inflammation and infection, smokers suffering from gum disease don’t respond as well to treatment. Smokers experience a higher rate of root infections, and smoking also slows the healing process after oral surgeries or trauma.

• Dry Socket

Smoking following a tooth extraction can cause a painful condition called “dry socket.” After extraction, a clot forms to protect the tooth socket. Just as this clot can be dislodged by sucking through a straw or spitting, it can also be dislodged by the force of inhaling and exhaling while smoking.

• Oral Cancer

Research has shown again and again that smoking is the single most serious risk factor for oral cancer. Studies have also shown that you reduce your risk of oral cancer significantly when you quit smoking.

• Consequences for Orthodontic Treatment

Finally, if this is the year that you’re investing the time and effort needed to create an attractive, healthy smile with orthodontic treatment, don’t sabotage yourself by smoking!

Cosmetically, smoking doesn’t just discolor your tooth enamel—tar and nicotine discolor your aligners and braces as well. If one of the reasons you chose clear aligners or ceramic brackets is for their invisible appearance, the last thing you want is yellow aligners and brackets.

More important, smoking, it’s been suggested, can interfere with your orthodontic progress. When blood vessels are constricted, your gums, periodontal ligaments, and bones can’t function at their healthy best, moving your teeth where they need to be steadily and efficiently. This means that your treatment could take longer. And if your smoking has caused gum disease, you might have to put any orthodontic treatment on hold completely until it’s under control.

Quitting smoking is a major accomplishment that will improve your life on every level. It’s always a good idea to talk to Dr. Kathleen Tavarez for strategies to help you achieve your wellness goals for the new year. Make this the year you stop smoking, and the year your health improves in countless ways because you did.

We’ve been celebrating the new year for a really, really long time. It goes way back, but it started formally in 1582, when Pope George XIII made January 1^st the official holiday for ushering in the new year. The idea was to yell, cheer, and blow horns to scare away all the evil spirits of the previous year with the hope that the new one would be filled with happiness and opportunity.

While scaring away evil spirits isn’t what’s on our mind these days, we still ring in the New Year by cheering and hollering with friends and family. It’s a time to set new goals, refocus on old ones, and look forward to all the surprises the coming year will bring.

Whether you’re saying hello to the New Year snuggled up at home on your couch in the Menlo Park or San Carlos, CA area or by gathering your friends for a social celebration, here are some tips to help ensure you welcome this new chapter with a smile.

Tips for a great New Year’s Eve celebration from Tavarez Orthodontics

• Stay safe. This one’s vital, because nothing puts a damper on your party like an emergency trip to the hospital. Stay responsible and try to plan ahead, whether that means taking a taxi, staying with a friend, or recruiting a designated driver. Do what you have to do to keep yourself and everyone around you safe.
• Spend time with the people you love most. The way we see it, the whole point of the holiday season is to cherish your family and friends. Regardless of what you’re doing, make sure there’s something for everyone. It’s essential to do something the whole group will enjoy!
• Smile! Whether you get all dressed to go out or have a quiet gathering with family and friends, make sure you accessorize with a smile. There’s always something to smile about!

We can all agree that change can be scary sometimes, but ringing in the New Year is an observance we all welcome with open arms. We hope you’ll enjoy this transitional holiday in a fun, healthy, and safe way. You have endless possibilities ahead of you!

From Dr. Kathleen Tavarez, have a fantastic New Year!
