DS is nearly 23 months. We brush his teeth thoroughly every evening before bed (and before his bottle of milk, too...) and occasionally in the morning (which is more of a struggle because it's just me and you sort of need two people). He's not at all keen on brushing, and very reluctant to show me his teeth without biting fingers. But recently I've noticed that his side incisors and canines have browny stuff on them. I can't tell if it's plaque or discolouration or what, because he won't let me check again after I've tried scraping with a fingernail! If it's plaque, it's pretty old and nasty, and I'm surprised it hasn't been brushed off. Do toddlers get other discolouration on their teeth like this?
His canines have got white blotches too, but it's the brown stuff that's bothering me. DS eats a lot of fruit between meals (he couldn't exist without snacks) as well as cheese and carrot sticks and raisins (cue cries of 'worse than chocolate!' but I'm not sure I agree). He also has the odd sweet biscuit or small piece of chocolate, but not that often. Do I need to take him to see a dentist? Am really at the idea that I might have let his teeth get manky.
