Hey!! What are the reasons for cavities in baby teeth? My 3 years old DD has cavities and I was shocked when her dentist in Cambridge told me this. He said it might be because she falls asleep with the bottle. He asked me not to worry and assure me that she will be alright after undergoing baby teeth cavity treatment. I feel guilty for not taking proper care of my DD. Has anyone had a similar situation? How did you overcome this guilty feeling?
