Radiographs, also known as x-ray images, are an essential diagnostic tool for all types of dental procedures. Taking x-rays is an important adjunct during a comprehensive exam because they help dentists visualize the inner layers of the teeth and bone that are not visible to the naked eye. X-rays play an important role in early and accurate diagnosis for tooth decay and are therefore essential for creating an ideal treatment plan for each patient.
What are Digital X-rays?
In the past, X-ray images were recorded by directing a beam of x-rays toward the teeth and other oral structures like gums and the jaw bones. The relative absorbance of these x-rays is then recorded by x-ray sensitive films. This process was not only time-consuming, but the results also varied and dependent on the operator’s skill and technique. Advancements in dentistry led to the birth of digital x-rays which are much more efficient and effective in capturing radiographs. Instead of using a radiographic film, digital x-rays use a very small digital x-ray sensor which is placed inside the oral cavity. The image recorded from the digital sensors is then immediately displayed on the screen.
What are the Uses of Digital Dental X-rays?
Digital x-rays provide a much better image quality than the conventional film, which is why most dentists have chosen to include digital x-rays as part of their diagnostic tools in the office. Below is a detailed list of the uses of digital x-rays:
- Diagnosing Teeth Cavities – While some teeth cavities, also known as caries, are visible during a clinical exam, most caries lesions develop inside deeper areas of the enamel or in between the teeth which are not visible to the naked eye. In these cases, digital x-rays are very useful for diagnosing teeth cavities. Tooth decay appear as shadows or dark areas inside the tooth on x-rays, which implies a loss of tooth structure due to loss of minerals from the decay.
- Visualize the Status of Developing Teeth – Digital x-ray images provide the dentist a clear view of the status of the eruption of the permanent teeth. They also provide information regarding which teeth have become impacted and are unable to erupt into normal occlusion. These are useful information to properly refer patients out to orthodontics to correct malocclusion at an early stage.
- Diagnosing Periodontal Problems – Periodontal infections are characterized by the loss of bone tissue around the teeth. The current level of the bone surrounding the teeth can be easily visualized on a digital x-ray. The bone and teeth appear lighter while the soft tissues tend to appear darker on an x-ray image.
- Diagnosing Dental Infections – The extent and severity of an infection around the roots of the teeth, known as a periapical infection, can be diagnosed with the help of a digital x-ray. In addition, digital x-ray images are also used during a root canal treatment procedure for evaluating and estimating the length and number of roots of a tooth. X-rays are also used for the diagnosis of swelling or cysts around the teeth.
- Treatment Planning – Because digital x-rays are useful in diagnosing cavities, infections and periodontal status, radiographs are essential in creating ideal and accurate treatment plans to address each patient’s dental needs.
What are the Different Types of Digital X-rays?
Dentists use different types of x-ray images for diagnosis and treatment planning:
- Periapical – This type of x-ray provides an image of the entire tooth including the top of the crown all the way down to its roots. Periapical x-rays are useful in diagnosing teeth cavities, periodontal issues, and infections or cysts around the roots.
- Bitewing – This type of x-ray provides an image of the biting surfaces of both upper and lower teeth. This radiographic image is helpful in detecting cavities especially ones forming in between the teeth as well as the integrity and fit of existing crowns and fillings.
- Occlusal View – The occlusal view provides an image of the floor of the mouth, which is primarily used for visualizing the status of development of primary teeth in infants and toddlers.
- Panoramic View – This is an extraoral image of the face and neck region. This image provides a view of the sinuses, teeth, jaws and their joints, and the nasal area. This image is highly useful for getting an good overall picture of one’s dentition, its roots and the surrounding bone.
- Cephalogram – This x-ray shows an image of the soft and hard tissues present in the neck region and is primarily used for preparing a treatment plan for patients with orthodontic problems.
What are the Benefits of Digital Dental X-rays?
In comparison to the conventional x-rays, digital x-rays carry several advantages:
- Lower Radiation Exposure – digital x-rays require very little radiation for capturing an image. Therefore, they are much safer than the conventional film x-rays.
- Improved Image Quality – digital x-rays provide high-resolution images of the tissues thus providing more diagnostic images for more accurate diagnoses for each tooth.
- No waiting! – Conventional x-rays may take up to 10-15 minutes for developing an image. On the other hand, digital x-rays are available to be viewed on the screen as soon as they are taken. Thus, the efficiency of digital x-rays are not only helpful for accurate diagnosis but also reduces chairside time for the patient.
- Easy Sharing – digital x-rays can be easily transferred between mobile and storage devices and can be easily shared with other providers. You don’t need to physically transfer carry the images and can be electronically transferred or stored in memory drives.
What Happens When You Don’t Take Digital X-rays?
Digital x-rays provide detailed information regarding the status of your teeth, gums and the jaw bones. Tooth decay or infections that are not be visible during a clinical exam can be easily detected from a radiograph image. If x-rays are not consistently taken at your regular dental visits, your dentist may not be able to diagnose cavities or periodontal problems at their early stages and therefore you would be at risk for more aggressive treatment once it’s detected at its later stages at which they would appear obvious to the naked eye. Larger decay can become more serious because they could lead to more aggressive and complex treatment, which may lead to more expensive fees and poorer prognosis for the tooth.
Digital x-rays are much safer than conventional film radiographs because they require less radiation. However, large amounts of radiation can still be dangerous and therefore digital x-rays are only taken when it is absolutely necessary like at every 6 month recall. Care must be taken while taking x-rays in pregnant women, and usually require a double lead apron to prevent the developing fetus from harmful radiation. Nevertheless, it is still recommended to take at least four bitewing x-rays at our regular dental checkups to ensure proper diagnosis and early detection of cavities and other dental issues.

I am not the biggest fan of the dentist, however this was the BEST dentist experience I have ever had! Everyone was so kind and I got everything I needed done in one visit!
Excellent service. Great first impression! Best cleaning I’ve had in several years, my mouth feels amazing. They even took the time to show me how to brush more effectively. My teeth are back to being pearly white.
They were very prompt and professional. I felt very comfortable in the visit. They have good exam specials without any hidden fees. I have found me a permanent dentist office. Thanks URBN staff.
URBN Dental provided great service and they were all so nice. They did a great job communicating with me and i would recommend to all.
I had a root canal and a crown done here, the entire process took about an hour. Will be back in 2 weeks for my final crown! Great doctor, great staff.
