Dental X-rays: The Inside Story

April 30th, 2020

We’re all friends here, so if you sometimes feel a bit nervous before your orthodontic appointments, no judging! Ask us about any worries you might have. We are happy to explain procedures, equipment, and your orthodontic options so you know exactly what is going on during treatment. And if X-rays are a concern, we can put your mind at ease here as well.

What Exactly Are X-rays?

Sometimes patients feel reluctant about the process of imaging because X-rays are a kind of radiation. But the fact is, radiation is all around us. We are exposed to radiation naturally from our soil and water, sun and air, as well as from modern inventions such as cell phones, Wi-Fi, and air travel.

Why is radiation so common? Because matter throughout the universe constantly gives off energy, and the energy that is emitted is called radiation. This radiation takes two forms—as particles (which we don’t need to consider!) and as traveling rays. This second type is known as electromagnetic radiation, created by photons traveling in regular waves at the speed of light.

We are exposed to electromagnetic radiation every day, because, whether we can see them or not, these different wavelengths and frequencies create various forms of light. Radio waves, microwaves, infrared, visible, and ultraviolet light, X-rays, and gamma rays are all part of the electromagnetic light spectrum.

Different types of radiation on this spectrum have different wavelengths and different frequencies, and produce different amounts of energy. Longer wavelengths mean lower frequencies and less energy. Because X-rays have shorter wavelengths and higher frequencies than, for example, radio waves and visible light, they have more energy.

How Do Dental X-rays Work?

An X-ray machine produces a very narrow beam of X-ray photons. This beam passes through the body and captures images of our teeth and jaws on special film or digital sensors inside the mouth (intraoral X-rays), or on film or sensors located outside the mouth (extraoral X-rays). These X-ray images are also known as radiographs.

Why are X-rays able to take pictures inside our bodies? Remember that higher energy we talked about earlier? This energy enables X-rays to pass through the softer, less dense parts of our bodies, which are seen as gray background in a radiograph. But some substances in our bodies absorb X-rays, such as the calcium found in our bones and teeth. This is why they show up as sharp white images in radiographs. 

There are many different types of dental X-rays used in orthodontics, including:

  • Occlusal X-rays, which show the entire arch of teeth in the upper or lower jaw.
  • Panoramic X-rays, which use a special machine to rotate around the head to create a complete two-dimensional picture of teeth and jaws.
  • Cephalometric X-rays, which show the patient’s entire profile, and the position and development of the teeth and jaws.
  • Cone Beam Computed Tomography, an external device which uses digital images to create a three-dimensional picture of the teeth and jaws.

Why Do We Need X-rays?

You might have noticed that these X-rays, unlike, for example, typical bitewing X-rays, don’t take images of individual teeth. That is because orthodontists deal with the teeth in relationship to each other and to the structures around them.

Beautifully aligned teeth and a healthy bite are the visible result of your orthodontic work, but there’s a lot going on above and below the surface that needs to be discovered and taken into account before your treatment even begins. X-rays help us evaluate:

  • The size, shape, and position of your teeth, including impacted teeth and wisdom teeth
  • The size, position, and health of your roots throughout treatment
  • The size and shape of your jaw bones, and how they affect your teeth alignment and bite
  • Your progress during different phases of treatment

How Do Orthodontists Make Sure Your X-rays Are As Safe As They Can Be?

First of all, the amount of radiation you are exposed to with a dental X-ray is very small. In fact, a typical panoramic X-ray provides roughly the same amount of radiation we are exposed to through our natural surroundings in just one day. Even so, Dr. Mark L. M. Powell and our team are committed to making sure patients are exposed to as little radiation as possible.

Radiologists, the physicians who specialize in imaging procedures and diagnoses, recommend that all dentists and doctors follow the safety principal known as ALARA: “As Low As Reasonably Achievable.” This means using the lowest X-ray exposure necessary to achieve precise diagnostic results for all dental and medical patients.

The guidelines recommended for X-rays and other imaging have been designed to make sure all patients have the safest experience possible whenever they visit the dentist or the doctor. We ensure that imaging is safe and effective in a number of ways:

  • We take X-rays only when they are necessary.
  • We provide protective gear, such as apron shields and thyroid collars, whenever needed.
  • We make use of modern X-ray equipment, for both traditional X-rays and digital X-rays, which exposes patients to a lower amount of radiation than ever before.
  • When treating children, we set exposure times based on each child’s size and age.

And now that we’ve talked about some things you might like to know,

Please Let Us Know If . . .

  • You are changing orthodontists and have had previous orthodontic X-rays taken. Ask to have your older X-rays sent to our office so we have a complete record of your orthodontic history. (With digital X-ray technology, this transfer can be accomplished with e-mail!)
  • You’re pregnant, or think you might be pregnant. Even though radiation exposure is very low with dental radiographs, unless there is a dental emergency, dentists and doctors recommend against X-rays for pregnant patients.

X-rays play an important part in helping us make sure your orthodontic treatment provides you with a lifetime of beautiful and healthy smiles. If you have any concerns, contact our Jenison, MI office. When it comes to making sure you’re comfortable with all of our procedures, including any X-rays that might be necessary, we’re happy to give you all the inside information!

Damon® Smile Benefits

April 23rd, 2020

Braces have come a long way over the years. In the past, tooth removal was common, palatial expanders were the norm, and headgear and rubber bands were necessary evils to get the desired results. Damon Smile self-ligating braces have made those things distant memories.

Despite the competition from other clear braces and aligners, Damon has a proven track record, and the results of a side-by-side comparison between conventional braces and Damon braces were published in the journal Clinical Impressions.

The Study

The comparative study tracked orthodontic care of 132 patients, six of whom were treated with Damon Smile, and 66 of whom got traditional braces. The study also looked at treatment times (meaning the total length of time the patients wore braces,) the number of appointments they had, the quality of the results, and patient comfort.

The Results

Length of Time Wearing Braces: The researchers found that the patients who wore Damon Smile braces wore them for an average of 7.2 months less than the traditional brace-wearing patients.

Number of Appointments: Damon patients had an average of 47.8 percent fewer appointments.

Time Needed for Leveling and Aligning: Damon patients only needed 3.2 months for leveling and aligning, while traditional brace participants needed six months. That means the Damon participants required 46.7 percent less time.

Comfort Level: Damon wearers experienced 60 percent less discomfort than traditional brace wearers.

Results: Damon results were consistently excellent, with a score of 3.6 on a 4-point scale.

Other Benefits

  • Damon Smile braces use a proprietary technology called self-ligation. That means there is no need for the elastic or metal ties that are part of traditional brace therapy. The absence of any kind of ties means that patients don't have to have their braces tightened.
  • Damon high-tech lightweight memory wires work faster, so patients don't have to wear braces as long as they would with traditional braces. Memory wire technology also reduces the need for frequent adjustments at our Jenison, MI office.
  • A slide mechanism holds wires in place, but allows for freer tooth movement.

Perhaps the greatest benefit of Damon Smile braces is that, without the ties, patients are far more willing to comply with a more time-consuming oral hygiene regime. More thorough brushing, easier flossing, and less general tension in the mouth mean that better oral hygiene lessens plaque build-up, while helping patients keep their mouths healthier and cavity-free during the time they wear braces.

Greater self-confidence and improved self-esteem have the potential to change lives. And a healthy mouth and an attractive smile can do that! Ask Dr. Mark L. M. Powell if Damon Smile is right for you!

Braces: Not just for kids anymore

April 16th, 2020

Despite the common assumption that braces are for kids, more and more adults are choosing to pursue orthodontics to correct their smiles. Just hearing the word “braces” and picturing a mouth full of metal can cause many grownups to hesitate about getting treatment for a straighter smile.

We’re here to give you the information you need to evaluate your treatment options and make the right choice for yourself. Whatever your personal history, wearing braces as an adult is an excellent way to create the straight, confident smile you’ve always desired.

What are my options?

Recent advances in orthodontic medicine have created numerous options for adults who need braces.

These are best for individuals who have severely crooked teeth or a significant bite problem, or who require other major orthodontic changes. The greatest drawback to wearing metal braces as an adult is the visible appearance of metal and wires.

Clear ceramic braces offer a solution to that, though they cost more. They’re are a good alternative for correcting highly crooked teeth or bite issues. Smoking or drinking red wine, soda, and other dark beverages may stain the adhesive that binds the brackets to your teeth, so you have to commit to being mindful and taking good care of them.

Another popular option for adults who need braces is a clear-aligner treatment, such as with Invisalign®. This system works in a different way from traditional braces by using a series of clear, retainer-like aligners.

In general, the Invisalign process lasts anywhere from three to 18 months. Keep in mind, however, that Invisalign is not as effective as traditional braces in treating bite problems or severe overcrowding.

The prospect of getting braces as an adult can be intimidating, but you should not let your fears prevent you from obtaining the smile of your dreams. A consultation at our Jenison, MI office with Dr. Mark L. M. Powell will address your concerns and provide more information about the best course of treatment!

When Does an Underbite Need Surgery?

April 9th, 2020

When does an underbite need surgery? The short answer is: when Dr. Mark L. M. Powell and our team recommend surgery as the best way to give you a healthy, functional bite. But let’s take a longer look, and see just why your doctors might come to that conclusion.

  • First, what exactly is an underbite?

In a perfect bite, the upper and lower jaws align, well, perfectly. Upper teeth overlap lower teeth very slightly, upper and lower teeth meet comfortably, and jawbones and joints function smoothly. When the alignment is off, it causes a malocclusion, or “bad bite.”

When we talk about an underbite, or Class 3 malocclusion, it means that the lower jaw protrudes further than the upper jaw. This protrusion causes the bottom teeth and jaw to overlap the upper teeth and jaw.

  • What causes an underbite?

Sometimes an underbite is caused by childhood behaviors while the teeth and jaw are developing, including tongue thrusting or prolonged thumb-sucking and pacifier use. (Working to stop these behaviors before they affect tooth and jaw formation is one of the many good reasons children should have regular visits with their dentists and pediatricians.)

Most underbites are genetic, however, and tend to run in families. It’s estimated that from five to ten percent of the population has some form of underbite. The lower jawbone (mandible) might be overdeveloped, the upper jawbone (maxilla) might be underdeveloped, both bones could be affected, or, sometimes, tooth size and placement might cause an underbite. These irregularities in jaw shape and size and/or tooth crowding are not something that can be prevented, and require professional treatment.

  • Why? What’s the problem with an underbite?

Even a minor underbite can cause difficulties with biting and chewing. A more severe underbite can lead to speech problems, decay and loss of enamel where the teeth overlap, mouth breathing and sleep apnea, persistent jaw and temporomandibular joint pain, and self-confidence issues.

  • Can’t my dentist treat my underbite?

Most probably not. A very mild underbite can be camouflaged cosmetically with veneers, but this does not address the cause of the underbite, and will not work for moderate or severe underbites.

  • Can my orthodontist treat my underbite?

Dr. Mark L. M. Powell will create an underbite treatment plan after a detailed study of each patient’s individual dental and skeletal structure. Treatment options will vary depending on the cause of the underbite, its severity, and even the patient’s age.

Early intervention is especially important for children who show signs of an underbite. That’s why we recommend that children visit our Jenison, MI office by the age of seven.

If an underbite is caused by tooth misalignment or crowding, braces can reposition the lower teeth. Sometimes extractions are necessary to make room for proper alignment.

If the cause is due to jaw structure, children’s bones are still forming, so treatment can actually help correct bone development. Palatal expanders, headgear, and other appliances are various methods of encouraging and guiding bone development.

But braces and appliances aren’t effective for every patient with an underbite, and especially in patients (usually those in their late teens and older) when the jawbones are already fully formed. In this case, we might suggest coordinating treatment with an oral and maxillofacial surgeon.

  • What does an oral and maxillofacial surgeon do?

An oral surgeon has the training, experience, and skill to help correct an underbite by surgically reshaping and repositioning the jawbone. This corrective jaw surgery is called orthognathic surgery.

  • What will happen during orthognathic surgery?

Your treatment will be tailored to your specific needs. Two of the common surgical procedures for treating an underbite involve repositioning the upper jaw to lengthen it and/or reshaping the lower jaw to shorten it.

Bone is sometimes removed or added, small bone plates or screws are sometimes used to stabilize the bone after surgery—your surgeon will let you know exactly which procedures will give you a healthy, functional bite. The surgery itself is most often performed under general anesthesia and requires a brief stay in the hospital.

  • How will my orthodontist and oral surgeon coordinate my treatment?

Correcting a Class 3 malocclusion can take time. Your oral surgeon will work together with Dr. Mark L. M. Powell to analyze the interrelationship of teeth, bones, and joints to determine dental and skeletal problems, and will develop the best treatment plan possible to create a healthy alignment.

  • So, when does an underbite need surgery?

Sometimes, a minor underbite can be corrected with braces and appliances alone. A serious underbite, however, will often require the specialized skills of both Dr. Mark L. M. Powell and an oral surgeon.

And, while it’s not the primary purpose of surgery, corrective jaw surgery and orthodontics can also make you happier with your appearance and boost your self-confidence. Achieving a lifetime of beautiful, comfortable, and healthy smiles—that’s the answer to your question.
