Prevention can help to save a lot of problems in the long run.
Prevention and good oral hygiene should start at an early age. Even before teething, babies should only have breast milk, formula or tap water to drink. At around 8 months old, the transition from bottle to cup is recommended as a bottle gives more exposure to natural milk which causes decay.
Baby teeth should be brushed from about 18 months of age with a small amount of low-fluoride toothpaste (children's toothpaste).
Diet is a big factor to preventative care, as it is clear that high sugar drinks and foods cause decay. Limiting high sugar foods is crucial to good health and less chance of decay.
In saying this, 6 monthly check ups are also vital as dentists have the ability to see problems underneath the tooth surface using x-rays, and are able to see which spots are being missed while brushing.
