Two years ago, i had a tooth cleaning at a dentist. Last week , i went to clean my teeth again. But this time the dentist told me that i have 5 decayed teeth. I cannot believe it at the beginning. Of course i had my 5 decayed teeth filled. I was also told that there are 4 wisdom teeth need to be pulled out since my teeth hurt because of that. I blame myself for not taking good protection of my teeth. If i had tooth cleaning more frequently, maybe i will not suffering so much more nowadays. So i want to know how often did you go to the dentist for a tooth cleaning?
