I know, it can be overwhelming. Eventually everything will fall into place.

As far as all your teeth being removed, that's not done automatically anymore. It depends on the condition of your teeth, and gums, and if compromised can they be repaired or then extracted. Before my initial radiation I had one extraction, one root canal and filling. During and after radiation utmost oral care is needed, including prescription fluoride for life.

On another note, after treatment, dental care is not covered such as the case with Medicare. Before treatment, if any dental work needed to have treatment is covered.
