Prior to a month ago, difficult child was brushing his teeth most nights (not well), but now it's like he doesn't even bother. It doesn't matter how much we remind him, he will lie and say he did it. I take him in every 4 months for a cleaning, and i imagine that will change to 3 months soon. Looking to the future, i see many problems due to his negligence, and i'll be darned if I'll be shelling out thousands of dollars for root canals, etc, etc... In the past i paid for two years of ortho expanders to fix his underbite & cross-bite, however, due to his "mouth breathing" his underbite is back completely. I can't do braces due to his not brushing or caring. I will be telling the dentist "pull it!" in the future if they even think about telling me he needs a root canal or $$ whatever!
