Dental x-rays are crucial in helping dentists examine areas between your teeth and under your gums that we cannot see with the naked eye. ‘Best practice’ guidelines suggest that routine dental x-rays should be done every 18 months to 2 years, depending on your age and dental disease risks.
Sometimes dental x-rays need to be repeated more frequently, but this is the exception to the rule and your dentist will specify when this applies to your particular situation.
