X-rays are an invaluable tool for us, allowing us to assess the cause and extent of problems that might not be immediately visible to the eye. They help us to identify which tooth is causing dental pain as patients often find it difficult to locate the offending tooth due to referred pain or infection.
There are two main types of x-rays: intra-oral and extra-oral x-rays. Intra-oral (taken inside the mouth) are the most common type and show the different aspects of the tooth or root. Extra-oral x-rays (taken outside the mouth) are used to detect dental problems in the jaw or sinuses and help in the extraction of wisdom teeth and orthodontic treatment.
