Nothing is as important as routine teeth cleaning. We tend to put this off because it is not an emergency and often families do not cover this in their budgets.. But the famous San Francisco Cosmetic Denist will help you with the costs. It is kind of what we do with car maintenance. This is a real shame because often the children are then faced with tooth decay or gum disease.Childen.are at high risk for tooth decay and so today a sealant can cover the chewing surfaces to prevent decay. This is a simple and fast procedure and it is certainly worth the cost. One sealant application can last for as long as 10 years.
