Do dentists write down exactly where each cavity is on a tooth?

No, dentists do not usually write down the exact location of each cavity on a tooth. Instead, they typically use a diagram or chart to indicate the general area of the tooth where the cavity is located. This is because the exact location of the cavity is not always important for treatment purposes, and it can be difficult to accurately pinpoint the location of a cavity on a small, irregularly shaped tooth.

In addition, dentists often use a variety of different instruments to examine and treat teeth, and some of these instruments may be difficult to use if the dentist is trying to write down the exact location of a cavity. For these reasons, dentists typically use a diagram or chart to indicate the general area of the tooth where the cavity is located.
