Dental X-rays are essential diagnostic tools we use at London Dental Specialists to examine what's not visible during a routine check-up. These images reveal your teeth roots, jawbone, nerves and sinuses, helping us detect issues before they become serious problems. We offer various types including bite-wing X-rays for detailed views of upper and lower teeth, periapical X-rays showing the entire tooth structure, and occlusal X-rays for comprehensive tooth development assessment. Many patients have questions about safety, frequency and necessity of these procedures. While the American Dental Association suggests annual X-rays, your specific needs may vary based on your oral health condition. Rest assured, we prioritise your safety, using modern equipment with minimal radiation exposure to provide the best possible care for your dental health.
What are dental X-rays and why are they important?
Dental X-rays (radiographs) are diagnostic images that show the internal structures of your teeth and jaws that cannot be seen during a visual examination. They are important because they help dentists at London Dental Specialists detect problems that may not be visible during a routine check-up, such as decay between teeth, infections in the bone, gum disease, abscesses, and abnormal growths. Early detection through X-rays allows for more effective and less invasive treatment options.
What types of dental X-rays does London Dental Specialists offer?
London Dental Specialists offers several types of dental X-rays, including:
- Bite-wing X-rays: Show details of the upper and lower teeth in one area of the mouth, particularly useful for detecting decay between teeth
- Periapical X-rays: Display the entire tooth from crown to root, showing how the tooth is anchored in the jawbone
- Occlusal X-rays: Larger images that show full tooth development and placement
- Panoramic X-rays (OPG): Provide a broad view of the entire mouth, including all teeth, jaws, sinuses, and temporomandibular joints
- Cone Beam CT scans: Advanced 3D imaging for complex cases and treatment planning
How often should I have dental X-rays taken?
The frequency of dental X-rays depends on your individual oral health needs. For patients with good oral health and no recent dental issues, X-rays may be recommended once every 12-24 months. Patients with active dental conditions, history of gum disease, or ongoing treatment may require X-rays every six months. At London Dental Specialists, our dentists evaluate each patient's specific needs, dental history, and risk factors to determine the appropriate frequency for dental X-rays.
Are dental X-rays safe?
Yes, dental X-rays at London Dental Specialists are safe. Modern digital X-ray equipment uses very low radiation doses—up to 90% less than traditional film X-rays. We follow the ALARA principle (As Low As Reasonably Achievable) to minimise exposure. Protective lead aprons and thyroid collars are provided for additional safety. The health benefits of detecting dental problems early through X-rays far outweigh the minimal risks associated with the very low radiation exposure.
Can pregnant women have dental X-rays?
While dental X-rays use very low radiation doses, at London Dental Specialists we take extra precautions with pregnant patients. We generally recommend postponing routine dental X-rays until after pregnancy. However, if you have a dental emergency or a condition requiring immediate attention, X-rays may be necessary. In such cases, we use double protective shielding and the most advanced low-radiation equipment. Always inform our team if you are pregnant or think you might be pregnant before any dental procedure.
What is an OPG X-ray and when is it needed?
An OPG (Orthopantomogram) is a panoramic X-ray that captures a complete view of your entire mouth, including all teeth, both jaws, sinuses, and temporomandibular joints in a single image. At London Dental Specialists, we recommend OPG X-rays for comprehensive evaluations, especially before complex treatments such as orthodontics, implants, or wisdom tooth extraction. OPGs are particularly useful for assessing tooth development, bone loss patterns, impacted teeth, and jaw abnormalities that cannot be fully visualised with standard dental X-rays.
Do dental X-rays hurt?
No, dental X-rays are completely painless. The process simply involves positioning small sensors in your mouth or standing/sitting still for panoramic images. There is no discomfort during the actual X-ray exposure. At London Dental Specialists, our experienced team ensures the process is quick and comfortable, typically taking just a few minutes to complete all necessary images.
How should I prepare for dental X-rays at London Dental Specialists?
No special preparation is required for dental X-rays at London Dental Specialists. We recommend maintaining your regular oral hygiene routine before your appointment. You may be asked to remove metal objects such as jewellery, eyeglasses, or removable dental appliances that might interfere with the X-ray image. If you have concerns about X-rays or have had recent X-rays at another practice, please inform our team beforehand and bring any existing X-ray records to your appointment to avoid unnecessary duplication.
Are there alternatives to dental X-rays?
While visual examinations are important, there are currently no effective alternatives that provide the same diagnostic information as dental X-rays. At London Dental Specialists, we use advanced digital imaging technology that significantly reduces radiation exposure while providing superior image quality. For specific concerns, we may use intraoral cameras or transillumination devices to supplement X-rays, but these cannot replace the comprehensive view of internal structures that X-rays provide for proper diagnosis and treatment planning.
