If you’re feeling a bit nervous before you visit our office for a surgical procedure, we want to make your visit as worry-free as possible. We are happy to explain procedures, equipment, and sedation options so you know just how safe and comfortable your experience can be. 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, WiFi, 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 medical and dental conditions which can be treated by oral surgeons. When the problem is primarily a dental one, we have several different X-ray options which can be used as necessary, including:
- Periapical X-rays, which allow us to look at one or two specific teeth from crown to root.
- Panoramic X-rays, which use a special machine to rotate around the head to create a complete two-dimensional picture of teeth and jaws.
- Cone Beam Computed Tomography, which uses an external machine to produce digital images creating a three-dimensional picture of the teeth and jaws.
Why Do We Need X-rays?
If all of our dental conditions were visible on the surface, there would be no need for X-rays. But since they are not, we use X-rays to discover such conditions as infection in a tooth’s root or bone, a decrease in bone density, and fractures or other injuries. And to properly plan treatment, we often require 3-D images, which show the spatial relationship of teeth, roots, bone, nerves, and sinuses.
Many dental procedures benefit from X-ray imaging for diagnosis and treatment planning, among them:
- Extraction of a seriously decayed or damaged tooth
- Wisdom tooth extraction
- Dental implant surgery
- Treatment of traumatic injuries
- Root surgeries such as apicoectomies and root amputations, which can save a tooth when infection recurs after a root canal
- Replacement of an avulsed, or knocked out, tooth
How Do Oral Surgeons 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. Theodotou 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 have X-rays from another doctor. We’ll let you know if your earlier X-rays might be useful, and how to transfer them. (With digital X-ray technology, this transfer can be accomplished electronically!)
- 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 a vital part in helping us diagnose and treat our patients. If you have any concerns, contact our Pooler 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!
