The frequency of dental X-rays depends on your individual oral health needs and risk factors. For most patients, bitewing X-rays are recommended once a year to detect cavities between teeth, while a full set of X-rays is typically taken every 3-5 years. If you have ongoing dental issues or a higher risk of dental problems, your dentist may recommend more frequent X-rays. Digital X-rays are safe and use minimal radiation to provide detailed images for accurate diagnosis.
