Digital radiography (digital x-ray) is the latest technology used to take dental x-rays.
Dental x-rays play an invaluable role for an accurate diagnosis of dental problems. They are both diagnostic and preventive in nature. Dental x-rays reveal cavities between the teeth or hidden by fillings, infections in the bone, fractures, gum disease, abscesses, cysts, and tumors. As with all technology, it is constantly improving, and it is such with digital dental x-rays.
Today, digital x-ray technology uses a special sensor to capture an image which is scanned instantly onto a computer screen, and provides multiple advantages over traditional x-ray film. Most importantly, digital technology cuts the radiation exposure to the patient by 50-80%.We are also helping the environment because digital x-rays do not use chemicals to develop. And it can be fun to watch the system work.
How often x-rays should be taken depends on your present oral health, your age, your risk for disease, and any signs and symptoms of oral disease.
