Doubt mouthwash would work. A water jet maybe.Ill admit it was my fault. I brushed every night before bed, but I ate lots of hard candy for the last couple of years. I had a cavity on that tooth and it was filled. A new cavity developed by the filling and resulted in the tooth you see above. Apparently the hard candy accumalted underneath the filling and wasnt completely removed with brushing alone. Ive only started using mouthwash as an extra precaution.
What they say about candy is true...watch it kiddos! D:
(Ive also been taking prednisone for years which made my teeth susceptible to this kind of thing)
And man, did that thing decay like crazy. On a side note, I pulled my wisdom teeth this morning.
