Aching Molar

My molar is aching. I have replaced the filling but it is sore. I may need to cap it to have a more permanent repair. Taking care of teeth is so important. B3 is only nine and he has decay in his permanent molar. I hope he will start to listen and inculcate the habit of brushing his teeth at least twice a day. I did not go to a primary school that has regular dental checkup and oral hygiene instructions. I munch too much on nuts, chips and cookies. Enjoy junk food and pay and pay.
