Do I really need to have x-rays when I get my teeth cleaned?
First, taking x-rays has gotten a lot easier with modern technology. Digital x-rays are a lot quicker and also lower your exposure to radiation.
Radiographs help the doctor to properly diagnosis the presence of disease, and we are not just talking about cavities. Radiographs help a dentist detect abcesses, cysts, and tumors that many times are symptom free. Also, many times waiting until a dentist can see you or until symptoms develop means that the cavity is large and most likely requires additional treatment other than a filling.
