I'm worried about my 18mth D's teeth. For the last 8 months she has been using the Easiflow cups (ones which don't drip and the child has to bite on the spout to release drink). The dentist commented on the fact her front teeth are further back than her other top teeth. Since then I have noticed that her middle lower teeth are also further back and I am now convinced that it is the result of the beaker spouts. I tried to drink from one to see and there is definitely a lot of pressure on those teeth to get liquid out.
Has anybody else experienced this and if I stop using them now, is it too late for her teeth to correct themselves?
