What is the difference between Dental X-rays and Are they safe?

Yes, Dental X-RAYS are safe.
They require exposure to very low levels of radiation—which makes the risk of potentially harmful effects very small—and most people only need one set taken every two years. The number of x-rays you need should be determined by your risk for gum disease and dental decay.

Most conventional dental x-ray machines use high-speed film, which reduces your exposure to radiation, plus some dentists use digital x-rays, which use about 80 percent less radiation than conventional ones. In general, dental x-rays emit lower levels of radiation than other medical x-rays.

Why do I need to keep getting X-rays?

Radiographs show the condition of your teeth, their roots, jaw placement, and the composition of your facial bones. They can help detect the presence or degree of gum disease, abscesses, and abnormal growths.

How can I reduce my exposure?
Check with your doctor if you have certain medical conditions or are undergoing treatments such as radiation therapy. Always mention these conditions or any changes in your health, and any other x-rays, you've had elsewhere. Also inquire if you doctor has the technology to do digital x-rays.

Are Digital Dental X-Rays Safe?
Some people do not want diagnostic x-rays because they have heard that the radiation is dangerous.  In fact, they pose very little danger. Dental x-rays are aimed in a tight beam at a small spot on the face.  The only structures that receive the full dose of x-radiation are the tissues in the direct line of fire. Digital X-Rays are safer, faster, more accurate and easier on the environment than traditional X-Rays. The traditional X-ray film development process requires the use and disposal of toxic chemicals. No chemicals are needed for digital X-rays, making it easier on the environment.

The Benefits of Digital dental X-rays to the Patient

Safer-Reduced exposure to radiation

Many patients have expressed concern about radiation exposure when receiving their dental X-rays. While they have wanted the diagnostic benefit of an X-ray, they have not wanted the radiation exposure. Digital X-rays eliminate that worry. Compared to traditional X-rays, digital X-rays reduce radiation exposure by as much as 85%.In addition. Digital x-rays are environmentally friendly.
Faster-Less waiting time

You will not need to wait as long for the results of your digital X-ray. Traditional X-rays take 8 to 10 minutes to process. One the digital sensor is placed next to your teeth; it takes only seconds for you digital X-ray to appear on the computer screen, ready to be viewed by your and your dentist.  As a result, you will benefit by having a much shorter appointment.

More Accurate-Better understanding of treatment

Digital X-rays are more accurate. Our dentist can enlarge images and enhance the contrast to your digital X-ray, making it easier for our dentist to see and diagnose any problems.

Digital radiography, or computerized X-rays, is part of the high-tech high-touch services that we provide to our patients at the office of Dr. Charles Lennon. Digital X-rays use less radiation than traditional film and offer many benefits to the patient.
