Has my 16 month toddler got a rotten tooth?
If the spot scrapes off and leaves white then it was just plaque or food stuck to his tooth. If he hasn’t been for a regular check up, I would start taking him. As soon as my kids got teeth I started getting them regular checks. My son has plaque on his teeth at his gum line, but the dentist says we’re doing everything right. I’m brushing closer to the gums now to help prevent any more buildup. As for my 2nd child, her teeth are so white all over. I believe some people are just prone to have bad teeth and have to work harder to keep them up.
