Parts of the crater walls eventually collapse back into the crater, the vent is filled with loose material, and, if the crater still is deeper than the water table, the crater fills with water to form a lake, the lake level coinciding with the water table.
Poor Dentition. My provider likes to use poor dentition in his assessment as a billable diagnosis, however there is not really a good code to select. Sometimes he is referring to a patient who is missing teeth due to poor oral hygiene, sometimes it is a patient with alot of tooth decay, in this case, he is referring to a patient with loose wisdom teeth.
Partial dentures are used when you still have some healthy teeth or it's not necessary to remove all of your teeth. Partial dentures are made with a plastic base, replacement teeth and metal framework to hold the structure in place. If only one or two teeth are missing, a permanent bridge is another option.
