My 1 year old started grinding her teeth about 2 months ago. About a week and a half after grinding her teeth she had 3 more pop up! In her case, she was grinding because it also felt good on her swollen gums...and it helped the other teeth break through. When it got really bad, I would take a cool wet washcloth and rub her gums...she seemed to stop grinding for a while after that. My pedi said that grinding is very common in this age group!
Doesn't it just sound terrible?!!! Like nails on a chalk board! Yikes!
