Bacterial action.: White spots associated with dental caries (cavities) are areas of the enamel that the bacteria have leached out the calcium. With calcium loss, you get a chalky-white appearance called decalcification.. Black, brown and tan represent the decayed aspect of the cavity. Decalcification can be reversed, decay can only be removed.
