When a child is born, he or she will have 20 primary teeth and 32 permanent teeth. But sometimes kids are born with additional teeth, and our team at Johnson Orthodontics calls this oral condition "hyperdontia." Primary teeth are the first set of teeth that erupt in your child's mouth, typically by the time they are 36 months old, and are shed by the time your child reaches the age of 12. Permanent teeth then take the place of the primary teeth and are usually fully-erupted by the time your son or daughter reaches 21 years of age. Anyone who develops more than 20 primary teeth or more than 32 permanent teeth has hyperdontia, and the additional teeth are referred to as supernumerary teeth.

While the cause of hyperdontia is not entirely clear, it is believed that there may be a genetic factor. Oral professionals have found that patients with extra teeth often have syndromes like cleidocranial dysplasia, Ehler-Danlos syndrome, Gardner syndrome, or cleft lip and palate. The prevalence of hyperdontia affects between one and four percent of the population in the United States, and the majority of cases are limited to a single tooth.

So, what is the best way to deal with hyperdontia? It really depends on the case. The treatment plan your doctor suggests varies according to the potential problem posed by the supernumerary teeth, as well as their type. Orthodontic treatment may certainly may help, but extraction can also be a good option. We recommend that children receive an oral evaluation or checkup no later than the age of seven. In addition to hygiene evaluation, this helps ensure your child does not experience hyperdontia problems.

If you suspect you or your child may be suffering from hyperdontia, please give us a call to schedule an appointment at our convenient Columbus, OH office to be evaluated.

You’ve been told that you have a malocclusion called an “underbite.” Let’s look at just what this diagnosis means, and what it means for you.

Just what is an “underbite”?

A malocclusion is another way of saying that you have a problem with your bite, which is the way your jaws and teeth fit together when you bite down. In a typical bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth.

An underbite, on the other hand, 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.

What causes an underbite?

Underbites tend to be genetic, and run in families, so, most often, an underbite is something you’re born with. The size of your jaws, the shape of your teeth, or both will affect your bite.

A smaller number of underbites develop because of injuries or early oral habits, such as prolonged and vigorous thumb sucking or tongue thrusting.

How do we treat an underbite?

Your treatment will depend on the type and severity of your underbite, and your age when treatment occurs.

• Braces and Aligners

If your underbite is a slight one, caused, for example, by crowded or overly large teeth, braces or clear aligners can help move the teeth into proper alignment.

• Functional Appliances

If the underbite 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 growing and forming.

If you’re a young patient, two appliances commonly used to help correct an underbite are palatal expanders, which gradually widen the upper jaw if it’s too narrow, and reverse pull headgear, which fits both inside the mouth and outside on the face, and provides a steady, gentle pull to encourage the forward growth of the upper jaw.

• Surgical treatment

In some severe cases, surgical treatment can correct an underbite by reshaping the jawbone itself and positioning it further back to align properly with the upper jaw.

Why treat your underbite?

A serious underbite can cause damaged teeth and enamel, painful problems with the temporomandibular joint, headaches and facial pain, sleep apnea, difficulty chewing, eating, and speaking, and can affect confidence and self-esteem.

By following your treatment plan, you’ll not only prevent these consequences, but you’ll achieve major benefits—a healthy, comfortable bite, and an attractive, confident smile. Want to know more? Talk it over with Dr. Dennis Johnson at our Columbus, OH office for all the information you’ll need!

This is one of the most common questions that is asked at Johnson Orthodontics and, unfortunately, it does not have a simple answer. Just as every patient we see is unique, so is their treatment plan. Some patients have very simple problems which require less appliances and time, while other cases are much more complicated and may require multiple appliances and phases.

The treatment fee usually reflects the amount of orthodontic work required to complete the treatment plan. The only way to find out how much braces will cost is to schedule a consultation with Dr. Dennis Johnson. During your consultation, we will perform a complete oral examination, listen to your concerns, and explain how we will address your needs.

Our findings will include the cost of orthodontics and how long the treatment will take to complete. Give us a call today at our convenient location in Columbus, OH for a consultation and discover how quickly we can make you smile!

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. Dennis Johnson 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. Dennis Johnson 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 Columbus, OH 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. Dennis Johnson will have all the answers you need to make that healthy bite and that confident smile a reality!
