This patient is a 26 year old woman who uses an Advair asthma inhaler. The inhaler causes dry mouth which allowed these cavities to form. If you use an inhaler always rinse out with water after and brush your teeth as soon as you can following inhaler use. Make sure to see your dentist regularly to check for tooth decay. The cavity in the last molar was to the nerve. I was able to avoid a root canal by placing a vitrebond pulp cap over the exposed nerve and a ceramic composite restoration to restore the tooth. Looks great!!!
