failure of a mother.

I'm writing anonymously because I'm so embarrassed and ashamed. I just got done at my almost 2 year olds dentist appointment and she already has 2 cavities. I hate myself I'm such a failure im terrified because she has to be put to sleep and get an IV in to get caps or crowns I dont even remember im bawling my eyes out I have done everything I could to keep her teeth healthy I have never had a cavity in my life I dont know how this could happen. Please tell me I'm not the only parents whose young child has a cavity and has to go thru this pain to get it fixed. I'm so fucking upset I want to fucking die I ruined my poor baby
