What is a palatal expander?

May 22nd, 2019

Orthodontists like Dr. Dennis Johnson recommend a first orthodontic visit and evaluation for your child around the age of seven. We will evaluate your child’s jaw and facial development and make sure that there is enough room in the mouth for the permanent teeth when they arrive. One of the recommendations we might make for early treatment is the use of a palatal expander. If you are unfamiliar with this device, let’s take a closer look at why it’s necessary and what exactly it does.

Why do we recommend the palatal expander?

There are two dental arches, composed of the upper and the lower teeth, in your child’s mouth. This arch-shaped design is meant to accommodate all the permanent teeth. Further, when the upper and lower teeth meet, they should result in a healthy occlusion, or bite.

Sometimes, the upper dental arch is simply too small to accommodate all of your child’s permanent teeth, leading to crowding, extractions, and impacted teeth. Also, a too-narrow arch can result in a crossbite, where some of the upper teeth bite inside the lower ones. An improper bite can lead to problems such as TMJ (temporomandibular joint) disorder, improper wear and stress on teeth, certain speech difficulties, and other potential complications. The palatal expander was designed to prevent these problems from occurring.

What is a palatal expander and how does it work?

The expander itself is a device that increases the size of the upper dental arch. Before your child’s bones are finished growing, the space between the two bones of the upper palate is filled with cartilage. This tissue is flexible when children are young, but gradually fuses solidly into place by the time they are finished growing (usually in the early to mid-teens). If the arch can be widened to accommodate the emerging permanent teeth, or to reduce malocclusions, this improvement can also affect the need for, and length of, future dental work.

There are several types of expanders available at our Columbus, OH office. These are custom-made appliances, commonly attached between the upper teeth on each side of the jaw. The two halves of the device are connected with a screw-type mechanism that can be adjusted to widen the upper palate and dental arch with gentle pressure. This is a gradual process, with small adjustments usually made once or twice a day to slowly move the bones further apart. As weeks go by, you will notice a successful change in the spacing of the teeth. Your child might even develop a gap in the front teeth, which is normal and will generally close on its own.

If you would like more detailed information, talk to Dr. Dennis Johnson about the palate expander. We can tell you what to expect from this treatment if we think it is best for your child’s unique needs, and how to make it as easy as possible for your child. Our goal is to provide your child with the healthiest teeth and bite possible, always making use of treatments that are both gentle and effective.

Safety of Dental X-Ray Radiation

May 15th, 2019

We all want to live our healthiest lives. We know that part of keeping ourselves healthy is regular visits to our Columbus, OH office for checkups and necessary dental work. And that dental work might require an X-ray. Should the amount of radiation in an X-ray concern us?

First, it is helpful to know that the radiation you are exposed to from a dental X-ray is very small. A set of most bitewing X-rays, for example, produces an amount of exposure about equal to the amount of background radiation we get from our normal surroundings in a typical day. We also take care to minimize your exposure even further by using specially designed equipment and protective shielding, and taking only necessary X-rays. If your child is very young, if you are pregnant, or if you have other health concerns, talk to us about the advisability of X-rays and whether they are essential to treatment.

Second, much of our careful general examination will be done visually. Dr. Dennis Johnson can check for cavities and other problems and assess tooth and gum health. But sometimes, there are conditions which can’t be detected without an X-ray.

  • Decay that isn’t visible in an oral exam—if a small cavity develops between teeth, or is hidden underneath a filling, an X-ray will catch it before more damage can take place.
  • Infection—An X-ray will reveal infections such as abscesses that can damage both bone and tooth, and gum disease that has harmed bone and connective tissue.
  • Orthodontic and periodontal issues—We might need an X-ray to determine the spacing and development of your child’s incoming teeth and maturing jaw structure, to properly create braces for adults or children, or to place an implant within the jawbone.
  • If you are a new patient, it is helpful to have complete X-rays taken as a baseline of your current dental health and previous dental work. This baseline allows us to track tooth and jaw development, if necessary, and to evaluate any future changes that might be a concern. (If you have had X-rays taken in another office, we can help you have them transferred so we have a background of your dental history.)

Even though the radiation from a dental X-ray is minimal, be assured that we will never request any unnecessary procedure. When we recommend an X-ray, we do so to make sure there is no decay or infection threatening the health of your gums and teeth, and that we have the essential knowledge we need to treat any dental, periodontal, or orthodontic condition. Because we all want to live our healthiest lives—and part of that healthy life is both active and proactive dental care.

Why Adults Are Choosing Invisalign®

May 8th, 2019

These days, it’s become more common to see adults at our office getting their teeth straightened with Invisalign clear aligners . . . that is, if you can see them! Whether they are seeking to overcome the stigma that “braces are just for kids,” or simply want straighter teeth without a mouth full of metal, Invisalign is an effective and easy solution.

According to the American Association of Orthodontists, from 1994 to 2010 the number of adults 18 and older who request braces increased by 58 percent: from 680,000 to 1.1 million a year. Many adults enjoy how discreet the aligners are and that the user doesn’t need to avoid any foods or make dietary changes the way you would with traditional braces. Also, each treatment is unique to the patient.

With an Invisalign treatment, you can expect to enjoy the following benefits over traditional braces:

  • The total treatment time is more precise with Invisalign because your treatment is modeled by a computer. Traditional braces depend more on an estimate and aren’t as exact.
  • You’ll make fewer trips to our Columbus, OH office, since you’re able to change your trays on your own every few weeks or whatever is prescribed.
  • Without brackets to place over your teeth, there’s less risk to the health of your tooth enamel.
  • Invisalign aligners are clear and practically invisible, so most people won’t even know you’re wearing them!

If you’re interested in Invisalign as a treatment option, please let Dr. Dennis Johnson know. We’d be happy to help you on your journey to a straighter, healthier smile!

Adults and Braces

May 1st, 2019

Nowadays, many adults are taking advantage of getting straighter teeth with braces. Dr. Dennis Johnson and our team love to help patients create the dazzling, confident smile they’ve always wanted.

Our adult patients usually fall into two categories: some had braces in the past but didn’t wear their retainers, while others are brand-new to wearing braces. Either way, both groups want the same thing: straighter teeth and a beautiful smile!

You will have several options for getting braces, depending on your financial situation and how quickly you would like your treatment to finish. Traditional metal braces are a less-expensive option and can help people who have severely crooked teeth. But many adults may not prefer this option because they dislike the appearance of metal brackets.

If you’re concerned about how you’ll look, we offer clear ceramic braces that aren’t as visible. These are more expensive than metal braces, and patients need to be careful with colored drinks that can stain them, such as coffee or red wine.

Another popular option is a clear aligner treatment called Invisalign®. This type is practically invisible; it uses a series of aligners that are customized to fit your teeth. The process of straightening your teeth can last anywhere from three to 18 months. For people who have extreme bite problems or crowded teeth, a different method may work better.

Don’t hesitate to call our Columbus, OH office today to set up a consultation. Dr. Dennis Johnson will help you choose the best option so you can be on your way to a straighter, more confident smile!
