Visiting the dentist is important. It can allow them to pick up problems early and hopefully stop them developing in to bigger issues. For example, if you have a cavity in your tooth you will most probably be able to have a filling where as if left it may be that the whole tooth needs to be removed.
Taking your child to a dentist from an early age is a good idea, not only can they check over their teeth to make sure that they are brushing properly but also to get them used to going so they do not develop a phobia of going to the dentist later on in life, especially when they get to the age that they may require work to be done.
Making sure that you get your child to brush their teeth properly twice a day is important along with choosing the correct toothbrush and also tooth paste.
