Radiation is very hard on your teeth. Without using flouride trays you run the risk of destroying your teeth and eventually losing them.

Shortly after finishing my 2nd round of OC, I ended up losing my teeth due to radiation damage. I am not a candidate for implants or even dentures so will live the rest of my life without teeth.

I suggest you immediately find a new dentist! Any dental professional who is not familiar with treating OC patients is not experienced enough to continue to treat you. Especially with the info they are already giving you. They are causing you and any other OC patient that comes thru their doors harm by being ignorant about OC and radiation. If I were you I upon getting a new dentist, inform your current dentist exactly why you left their practice. Ignorance is NOT an excuse! They are a professional and their lack of knowledge could cause you or other OC patients great harm.
