In theory as soon as they have teeth I’ve never taken my son he got his first teeth at 5 months and now has 12 teeth but speaking to others have older kids they said they didn’t really feel it was necessary until 2ish and I brush my sons teeth twice a day so unless there’s an issue I’ll wait a bit longer. I don’t go as I don’t have any issues (I went once when pregnant as hadn’t been in 9 years and they said my teeth were perfect) so I can’t take him in for that x
As soon as they have teeth! It's more to get them used to going than for any actual treatment. My LO comes with me every 6 months. He sits on my lap and the dentist just had a look in his mouth then gave him a sticker x
