What is a bitewing X-ray?
A bitewing is a small dental X-ray of the back teeth that shows both the upper and lower teeth in one image. It is mainly used to detect cavities between the teeth and to assess the bone level around them. Because cavities between teeth are often difficult to see, bitewing X-rays are an important part of dental check-ups.
What is the difference between a bitewing and a periapical X-ray?
A bitewing mainly shows the crowns of several back teeth at once and is commonly used during routine check-ups. A periapical X-ray focuses on one specific tooth or molar and also shows the root and surrounding bone. This helps the dentist assess whether there is, for example, an infection or damage.
How often does a child need dental X-rays?
How often X-rays are needed depends on your child's oral health and risk of dental problems. Children with a higher risk of cavities may need check-up X-rays more often, while those with healthy teeth may need them less frequently. X-rays help the dentist detect small problems before they become bigger ones.
When are X-rays used for dental problems?
X-rays are often taken when the dentist suspects a problem that cannot be seen directly, such as a cavity between the molars or an infection near the root. They help determine which treatment is needed, for example for cavities (caries) in children or a damaged tooth after dental trauma.
