My DS has just turned 2 and he has what looks like a build up of plaque on the back of his two bottom front teeth 
No amount of brushing will remove it. I've even tried to scrape it off (gently) with my nail but he won't co-operate.
I just don't understand how this has happened. We have brushed his teeth twice a day, every day since they first appeared. He only drinks water and milk and has a very healthy diet. Where am I going wrong?
I feel so guilty but I can't think of anything I should have done differently.
I'm trying to get him an appointment with the dentist but will they even be able to do anything? DH and I have to pin him down to brush his teeth so I can't imagine he's going to open his mouth for the dentist!
Has anyone had similar with their toddler and have any advice? This is probably a stupid question, but is there such a thing as an electric toothbrush for toddlers??
Any advice would be very much appreciated. I feel like a terrible Mother.
