I noticed half her back tooth missing when I brushed her teeth tonight(shes 4). She was at childminders/nursery today but don't think she had a fall bad enough to break it. I feel awful- casn't help thinking was it me not brushing her teeth properly that it's deteriorated? She says its not painful but is very jagged. I'm going to call the dentist in the morning. Thing is I was about to make her first appointment and now she may end up having a filling, poor scrap. Any ideas what they may do please? Thankyou.
