About sealents: Tooth decay is the most prevalent dental disease among children. Dental sealants can be safely reduce tooth decay and preserve a smile for years to come! Sealants are simply a thin plastic coating applied to the chewing surface of the back teeth as a means of helping to prevent tooth decay. The white film (plaque) that remains on the teeth over time causes tooth decay and without proper removal, it forms a cavity. Sealants are an effective way of blocking plaque from forming on hard-to-reach areas with your toothbrush. They are typically applied to permanent molars and premolars, but can be applied to baby teeth. Sealants can be clear, white or tinted and can’t be seen when you talk or smile, because they are only applied to the back teeth.
