Preventative care encompasses a regular check-up and clean, fluoride treatments and fissure sealants. Fluoride treatments are provided at the end of every clean to help strengthen your teeth against the acidic food and drinks we ingest. Fissure sealants are placed on teeth with deep fissures and grooves to prevent them from becoming plaque traps that can lead to decay. They are also commonly placed during adolescence as children are often at the highest at-risk age group for getting decay.
