The frequency of dental x-rays depends on your individual oral health condition. Typically, a healthy adult without recent cavities or dental issues may not require x-rays at every appointment. However, if your dental situation is less stable and your dentist is closely monitoring your progress, more frequent x-rays may be necessary.
If you're uncertain about the purpose of a specific x-ray, don't hesitate to ask your dentist. It's important to note that dental x-rays involve minimal radiation exposure and serve as a crucial diagnostic tool for your dentist to identify and prevent minor issues from escalating into major problems.
