Genuine ask as I don't know if this is normal or not.
Friends 4yo has 5 tooth cavities and has to have coatings put on their teeth. Seems to me like a lot but as my child is only 1 ive no experience apart from my own and according to my mum me and my siblings never had any.
A few days after the dentist visit she has been contacted by her hv calling her younger child in for a check up. Might be a coincidence but possibly linked?
I know kids dont have great brushing technique and its hard to get their teeth properly cleaned if they don't like it, and I know that 1st teeth dont need to last that long anyway so might not be that big of a deal but just wondering really whether its common or not for kids teeth to deteriorate by this age or whether its something you can prevent?
