Dental Xrays Early detection of caries and gum disease

tooth decay can develop in areas you can’t see, even when looking in the mirror or during a routine dental check-up? This is where the Bitewing X-ray comes in — the magical tool that gives your dentist “an extra pair of eyes” to detect cavities and gum disease before they cause you any pain or major problems.In Dalily Medical, we’ll take you on a simple, informative journey to understand everything you need to know about Bitewing X-rays: what they are, when you need them, how they’re done, and whether they’re safe — plus tips to keep your smile healthy for years to come.

What is a Bitewing X-ray?

A Bitewing X-ray is a type of intraoral X-ray that shows the crowns of the upper and lower teeth in a single image, along with part of the alveolar bone that supports the teeth.
It is called “Bitewing” because the patient bites down on a small wing-shaped device during the imaging process.

When Does the Dentist Order a Bitewing X-ray?

Bitewing X-rays are used in several situations, including:

Detecting cavities between the teeth.
Assessing the level of supporting bone to check for gum disease.
Examining the condition of fillings and crowns after placement.
Monitoring the progress of dental or periodontal treatment.
Evaluating the spread of decay under old fillings.

Steps of Performing a Bitewing X-ray

1. Preparing the Patient

The patient wears a lead apron to protect against radiation.
The dentist explains how the device will be placed inside the mouth.

2. Positioning the X-ray Film or Digital Sensor

The film or sensor is placed inside the mouth to cover the target area.
The patient is asked to gently bite on the designated part.

3. Taking the Image

The X-ray machine is precisely aligned toward the film or sensor.
The image is captured within seconds.

4. Reviewing the Image

The dentist views the image on a screen (for digital X-rays) or on traditional film.
The results are analyzed immediately.

Advantages of Bitewing X-rays

Early detection of cavities before they cause pain or complications.
High accuracy in showing spaces between the teeth.
Quick and painless procedure.
Relatively low radiation dose.
Digital imaging option for faster results and easy image storage.

X-rays Safe?

Yes, Bitewing X-rays are considered safe, especially when using lead aprons and modern digital imaging techniques that reduce radiation exposure.
The radiation dose from a single image is roughly equivalent to what a person naturally receives from the environment in one day.

⚠️ Note: X-rays should not be repeated unless medically necessary, especially for pregnant women in the first trimester.

How Often Should You Have a Bitewing X-ray?

People with healthy teeth: Every 1–2 years, based on the dentist’s evaluation.
People at higher risk of cavities or gum disease: Every 6–12 months.
Children: Regularly, to monitor tooth development and detect cavities early.

Difference Between Bitewing X-rays and Other Dental X-rays

Type	What It Shows	Main Use
Bitewing X-ray	Crowns of upper and lower teeth in one area + supporting bone	Detecting cavities between teeth and gum disease
Periapical X-ray	Entire tooth from crown to root	Diagnosing root or deep bone problems
Panoramic X-ray	Full view of both jaws and all teeth	Comprehensive assessment before surgery or implants
Occlusal X-ray	All teeth in either the upper or lower jaw	Checking growth or abnormalities

Bitewing X-rays for Children

These X-rays are extremely important for children because they help:

Detect early tooth decay.
Monitor the growth of permanent teeth.
Prevent complications from untreated cavities.

Tip for parents: Don’t wait for pain before getting an X-ray — prevention is always easier than treatment.

Patient Preparation Before a Bitewing X-ray

Bitewing X-rays require no special preparation, but it’s best to:

Brush your teeth before the appointment.
Inform your dentist if you are pregnant.
Remove any metallic jewelry near your face.

Modern Technologies in Bitewing X-rays

Digital Bitewing X-rays
Provide instant, high-quality images with the ability to enlarge and highlight suspicious areas.
3D Imaging (in some advanced devices)
Offers more detailed views of the teeth and surrounding bone structure.

Cost of Bitewing X-rays

Costs vary by country and equipment used:

Egypt: 50–150 EGP per image.
Gulf countries: 20–50 SAR per image.
Europe & USA: $10–$30 per image.

Frequently Asked Questions (FAQ)

1. Do Bitewing X-rays cause pain?
No, the procedure is painless, although some patients may feel slight discomfort from the device inside the mouth.

2. How long does the procedure take?
Usually less than 5 minutes.

3. Can young children have these X-rays?
Yes, with special sizes designed for a child’s mouth.

4. Are there alternatives to Bitewing X-rays?
Panoramic X-rays or 3D imaging may be used, but Bitewing X-rays remain the most accurate for detecting cavities between teeth.

Conclusion

Bitewing X-rays are an essential tool in dentistry for the early detection of cavities and gum disease. Thanks to their accuracy and ease of use, they allow dentists to provide timely treatment before problems worsen, helping maintain healthy teeth for many years.

Remember: Regular check-ups with Bitewing X-rays can save you pain, time, and money in the long run.
