2 year old hardly brushed teeth..should I be concerned?

Omg I’m so worried!!! My 26 month old literally hardly ever wants to brush his teeth. The odd time he allows me to get a good cleaning. But most of the time its just him wanting to suck the tooth paste off 🤦🏻‍♀️ (fluoride free btw!)

I try to always give him water after milk and such. But I’m so so worried. Is this normal? Should I be concerned? Any ideas? Anything that helped you?

I bought him a tooth brush that vibrates like ours and bought him woody and buzz tooth brushes since he’s obsessed with toy story, and these all made him have an interest in putting the tooth brush in his mouth, but that’s about it.
