Our patient was having sensitivity on several teeth while eating and drinking sweet things. We found several large cavities in the pits and grooves of her molars.We used a green dental dam to isolate the teeth and prevent anything from contaminating the teeth. We then removed the cavities and rebuilt the teeth using white, tooth-colored composite filling material. We adjusted the bite after removing the dental dam and polished to make sure there were no rough areas. These fillings should last a long time with excellent home care and routine cleanings.
