Some primary teeth will remain until the age of 12. The tooth that needs a filling may very well be one of those teeth. Broken and infected teeth can affect your child's health and self-esteem.
When repairing a tooth, the dentist removes the decay and fills the tooth with an amalgam or composite material. A filling can be an easy and economical way to remedy a problem that, if left untreated, could cause the child pain. Repairing the tooth will also stop the cavity from getting bigger.
If the tooth is not repaired, and the decay spreads, it may be necessary to extract the tooth. When a primary tooth is missing, the teeth around it may take its place and thus prevent the permanent tooth from growing. To maintain the space, your dentist can place a plastic or metal space maintainer on the adjacent teeth which allows the permanent tooth room to grow.
