Visiting the dentist for cleanings and exams is part of maintaining a healthy smile. But what about dental X-rays? If you’ve been wondering why some people get X-rays during every visit to the dentist while others don’t, you’re not alone. Understanding the reasons for dental X-rays can help you appreciate the role they play in your oral health.
Regular dental X-rays allow your dentist to look deeper than what’s visible to the naked eye. X-rays help identify potential dental problems early, they explain changes in your teeth or jaw, and they provide insight into your oral health. Knowing what’s happening beneath the surface of your gums and teeth can also help your dentist monitor any changes that may be happening in your teeth.
The Importance of Regular Dental X-Rays
X-rays are an essential diagnostic tool in dentistry, as they provide a closer look at the unseen areas of your teeth, gums, and bone structure. They allow your dentist to detect potential issues that may not yet cause discomfort or visible symptoms like oral cancers.
Most dental problems do not cause pain or discomfort until the problem is well underway and marinated with time.
What Do X-Rays Reveal?
X-rays provide detailed images that uncover concerns that a visual examination alone cannot, such as:
- Tooth decay between teeth or beneath existing fillings.
- Bone loss due to gum disease.
- Abscesses or infections at the root of the tooth under the gums.
- Positioning issues of incoming teeth (especially in children and teens growing wisdom teeth).
- Health of tooth roots and jawbone structure.
By detecting issues early, X-rays help prevent minor dental concerns from escalating into major oral health problems, saving time, discomfort, and money in the long run.
How Often Are X-Rays Needed?
The frequency of X-rays depends on factors like your age, dental history, and overall oral health. While some patients may require X-rays every 6–12 months, others with no history of cavities or gum disease might need them less frequently.
Children, for instance, might need X-rays more often to monitor the growth of their teeth and detect cavities early, as their teeth and jawbones develop quickly. Adults with ongoing dental issues, such as tooth decay or gum disease, may also require more frequent imaging.
At Northwest Dental Centre, we personalize X-ray recommendations to suit your unique health needs, ensuring your smile gets the care it deserves.
Are Dental X-Rays Safe?
If you’ve hesitated about getting X-rays due to concerns about radiation exposure, it’s important to know that dental X-rays are very low-risk. Modern equipment uses minimal radiation, and safety protocols like lead aprons and thyroid collars add extra protection.
For context, the radiation exposure from a set of dental X-rays is comparable to the amount you’d naturally absorb from natural environmental sources in a single day.
Your dentist is always happy to discuss any concerns you have. Transparency and comfort are central to the care we provide at Northwest Dental Centre. No radiation is good radiation, so we try to do only what is necessary for your health needs.
What Can You Expect During a Dental X-Ray?
Dental X-rays are quick, painless, and non-invasive. Here’s a step-by-step guide to what typically happens during the process:
- Preparation: Your dental technician will provide a protective lead apron and, if needed, a thyroid collar to shield your body. The aprons aren’t necessary with our advanced digital technology, but they make people feel more comfortable.
- Positioning: You may be asked to bite down on a small device that holds the X-ray film or sensor while the machine captures images of your teeth and jaws.
- Imaging: The technician takes several images from different angles, ensuring a comprehensive view of your oral health.
The entire process takes only a few minutes and seamlessly integrates into your regular dental exam.
If specific concerns arise, such as ongoing tooth pain or a suspected cavity, additional X-rays may be taken to focus on those areas.
The Types of Dental X-Rays
Different types of X-rays serve various purposes, helping customize the care you receive:
- Bitewing X-Rays reveal decay between teeth and monitor alignment.
- Periapical X-Rays show the entire tooth, from crown to root, to detect root infections or bone changes.
- Panoramic X-Rays provide a full view of your mouth, showcasing teeth, jaws, and the surrounding structures—ideal for detecting impacted teeth or planning orthodontic treatments.
- CBCT - Cone Beam provides a three dimensional view to find the best bone to place implants, helps us find teeth with dead nerves, and to map vital structures to increase safety during surgical procedures.
Beyond X-Rays: Dental Exams
While X-rays are vital, they’re just one part of maintaining oral health. Your dental exam also includes a range of checks to ensure your teeth, gums, and mouth are in good shape.
During your visit at Northwest Dental Centre, we’ll examine for:
- Cavities and cracked teeth.
- Signs of clenching or grinding.
- Gum inflammation or recession.
- Indicators of oral cancer.
We pair these checks with professional cleaning to remove plaque and tartar buildup, polish your teeth, and provide fluoride treatment as needed.
