I feel like a 💩 mom

My daughter went to her regular dentist checkup yesterday and I found out she has a cavity. She’s only five. I never had a cavity until I was an adult. I brush her teeth meticulously. We floss and use mouthwash. Dentist every six months. I don’t understand how it happened. I know this isn’t an end all and it happens but I’m still so mad at myself.

The hygienist was not nice to me and asked what her diet was like. I was honest, I don’t think It’s bad. She doesn’t drink juice, maybe a sprite every few months as a treat with pizza night. But when she heard I give her goldfish and crackers as snacks for school she went on and on about how bad they are for your teeth and carbs are just sugar. At five years old her diet is like 10 things total. I just felt so defeated.
