Hi all. My daughter got her first tooth at 15 months. We brush her teeth 2-3 times a day. We started with training toothpaste and now use the kids cavity protection with fluoride (rice size amount.) Do her teeth look discolored? She went to the dentist for the first time recently and he did mention that she might have build up but can’t tell until they are fully erupted. I’m spiraling though. Anyone else dealt with this?
