Why dentists use x-rays
Dental x-rays help show cavities between teeth, bone levels around teeth, infections, impacted teeth, and problems under old fillings or crowns. These areas cannot always be seen during a visual exam.
Digital x-rays use sensors and software to capture images quickly, often with lower radiation than older film methods.
Frequency is based on risk
A patient with recent cavities, gum disease, dry mouth, or tooth pain may need x-rays more often than someone with stable oral health. Children and teens may also need growth-related checks.
If you are unsure why an image is recommended, ask. A good dental team should explain what the image helps evaluate.
Tell the office if anything changed
Pregnancy, recent medical treatment, new medications, and recent x-rays from another office are worth mentioning. The dentist can decide what is needed for your situation.
Dental Care of Woodstock uses imaging to answer a clinical question, not as a routine add-on without purpose.
Common questions
Are dental x-rays safe?
Dental x-rays use low radiation, and digital imaging can reduce exposure. The dentist recommends images only when the diagnostic benefit matters.
Can I transfer x-rays from another dentist?
Often, yes. Recent clear x-rays can be useful, but new images may still be needed if symptoms or image quality require it.
