Sounds like you're doing everything right! As a kid, I was always the one to brush and floss but somehow always had to have a cavity filled. My brother on the other hand never flossed and didn't brush every but NEVER had a single cavity. 🤷🏼♀️🤷🏼♀️
Maybe try a dry brush (wet toothbrush, but no toothpaste) every time you collect his plate. You can let him do it. It doesn't have to be perfect if you are doing his main brushes. Being mindful about water after meals is great advice and just a great habit overall. I'm going to start today 😁
It’s not from breastfeeding….
Hey I’m a dental assistant! Don’t feel terrible please, some peoples genetics play a big role in the development of cavities. If you’re brushing and flossing and keeping sugar to a minimum then you’re doing everything you can! Biggest advice I can give is make him drink water after eating and drinking so nothing is sticking on his teeth for prolonged periods of time. Some pediatricians will apply fluoride varnish to the teeth at check ups so look into requesting that at his next doctors appointment
