as far as I know only the essential things, so check-up twice a year, and repairing teeth, not the whitening, since that is cosmetic, not medical
I asked my husband, a dentist, and he said the medication can cause dry mouth, so be sure you get your teeth cleaned regularly. Also, when you go to a dentist tell him you are taking the medication because some antibiotics can cause adverse reactions (like erythromycin) when taken together. Thye dentist will know to prescribe an antibiotic that is safe to take with Geodon.
