Digital dental X-rays can help a dental team capture, view, store, and use images efficiently. They may support clearer discussions and treatment planning, but they do not replace a clinical examination, and an X-ray is not automatically needed at every appointment. The type and timing of imaging should reflect your individual clinical needs.
For patients comparing dental care in London, Ontario, the important question is not simply whether a clinic offers digital imaging. Ask what the image is intended to assess, how it may influence your care, and whether it is appropriate for your situation.
What Are Digital Dental X-Rays?
Digital dental X-rays use an electronic sensor or similar system to capture radiographic images of the teeth and surrounding structures. Instead of developing film, the image is processed electronically and can generally be displayed on a computer or other screen. Digital intraoral radiography has been studied in relation to clinical workflow and image use, although experiences vary with equipment, technique, and clinic procedures. Read the systematic review of workflow with digital intraoral radiography.
“Digital” describes how an image is captured and handled. It does not mean every image is automatically clearer, that every dental problem will appear, or that an X-ray replaces an examination. A dentist must select the appropriate image, obtain it correctly, and interpret it alongside your symptoms, history, and clinical findings.
Benefits of Digital Dental X-Rays for Patients
These are potential benefits of digital dental radiography in general, not guarantees about the speed, equipment, or results of a particular clinic.
1. A More Efficient Imaging Workflow
Digital systems can reduce the need for film development and related processing. An image may be available for review within the clinic’s electronic workflow, helping the team move from image capture to discussion and planning without handling physical film.
This does not guarantee a shorter appointment. Images may need to be retaken if positioning or quality is inadequate, and the dental team still needs time to assess the findings. The potential benefit is a more streamlined process, not an instant result. Review the evidence on digital radiography workflow.
2. Images Can Be Viewed and Discussed More Easily
A digital image can often be displayed during a consultation, allowing the dental professional to discuss the relevant area with you. Depending on the system, display adjustments may also help with viewing. This can make a conversation about a tooth, bone structure, or area of concern more concrete.
Accessible images do not make a patient the interpreter. Digital tools can support education and communication, while diagnosis and treatment decisions remain the responsibility of the dental professional. Read about digital intraoral radiography in clinical dentistry and review the Canadian Dental Association’s position on new technology.
3. Simpler Record Access and Sharing
Electronic images can be stored as part of a patient record rather than kept only as physical film. They may be easier to retrieve during a later visit and may support sharing when care is transferred or another professional’s opinion is needed, subject to the clinic’s systems, privacy practices, and consent requirements.
This can help if you have moved, changed dentists, or need more than one type of dental service. It does not mean every clinic can instantly access another provider’s images. Ask how records are requested, transferred, and retained. See the Ontario study of radiographic imaging technologies.
4. Support for Diagnosis and Treatment Planning
Dental X-rays can show structures that are not fully visible during a visual examination. Depending on the clinical question, imaging may help assess a tooth before restorative treatment, investigate symptoms, or support planning for root canal therapy, periodontal care, orthodontic treatment, or urgent care.
An image is one part of an assessment. A dentist may combine it with your history, symptoms, examination, and other information before recommending care. Read the FDA guidance on selecting patients for dental radiographic examinations.
Digital Does Not Mean Risk-Free: Understanding Dental X-Ray Safety
Digital dental X-rays still involve X-ray radiation. The relevant safety question is whether an examination is justified for a specific clinical purpose and performed using appropriate procedures, not whether the technology is risk-free. Learn about medical and dental X-rays from Health Canada and review Safety Code 30.
- Clinical justification: The team should explain what the image is intended to assess.
- Appropriate technique: Equipment, positioning, and operating procedures matter.
- Avoiding unnecessary repeats: Mention recent images from another provider.
- Relevant health information: Tell the dental team if you are pregnant or may be pregnant, or have another relevant concern.
These points do not establish a fixed schedule for everyone. Children, adults, new patients, returning patients, and people with symptoms may have different clinical needs.
When Might a Dentist Recommend Dental Imaging?
A dentist may consider an X-ray when an examination or symptom raises a question that imaging could help answer. Examples include pain, sensitivity, swelling, injury, areas not fully visible during examination, pre-treatment assessment, evaluation of bone or tooth roots, and monitoring a known concern.
These examples are not diagnoses and do not mean imaging is always required. The type, number, and timing should reflect the dental professional’s assessment. See the FDA guidance on dental radiographic examinations.
Questions to Ask Before Having a Dental X-Ray
- What is this X-ray checking? Ask which symptom, tooth, structure, or treatment question it relates to.
- Which type of image is recommended? Different images answer different clinical questions.
- How could the result change my care? This connects imaging to a possible next step.
- Do you need previous images? Tell the team where and when earlier imaging was completed.
- Is there anything about my health I should mention? Share relevant information before the examination.
- How will the image be stored or shared? Ask about record transfer if you are changing providers.

Frequently Asked Questions
Are digital dental X-rays safer than traditional film X-rays?
Digital systems may have workflow and image-handling advantages, but they still use X-rays. Safety depends on appropriate clinical selection, technique, and avoiding unnecessary exposure.
Do I need dental X-rays at every check-up?
Not necessarily. The need and timing depend on your examination, history, symptoms, age, prior images, and the clinical question being assessed.
Can I ask my dentist to explain why an X-ray is needed?
Yes. Ask what the image is checking and how the result could influence your care. A clear explanation can help you make an informed decision.
What should I tell my dentist before having a dental X-ray?
Tell the team about pregnancy or possible pregnancy, relevant health information, recent imaging, and any symptoms or concerns.
Making an Informed Decision About Digital Dental X-Rays
The main digital dental X-ray benefits are practical: digital imaging may support efficient capture and processing, easier viewing, more accessible records, and treatment planning. Those advantages matter most when the image answers a clear clinical question and is interpreted alongside an examination. Digital imaging does not guarantee a diagnosis or mean every patient needs an X-ray at every visit.
Before your next appointment, bring information about recent imaging, share relevant health circumstances, and ask what the recommended image is intended to show. If you are overdue for care or have a new concern, book an appointment with Patel Dental Center to discuss your dental imaging and care needs.
