Preventive Resin Restoration (PRR) is a term used to describe a composite filling material placed into the deep groove on the top side of a tooth to prevent cavities from forming in the groove. Preventive Resin Resotrations are often referred to as Sealants but differ in two significant ways. The first is the tooth grove is mechanically cleaned and shaped by Dr. Greg. This step makes sure no decay or organic material is left under the filling material and is sometimes diagnostic of occult caries. The second difference from sealants is the resin itself. We use a Flowable Composite for our PRRs. This material has a sintered glass particle content of over 60% that give the filling material strength and wear resistance over traditional sealant materials.

While sealants can be placed by school programs without dentist supervision, expect them to chip out of the tooth at an average rate of 10% per year. Preventive Resin Resotrations are much more durable and expected to last a lifetime. We maintain our PRRs over the years a patient sees us, and we guarantee them for coverage until a patient “graduates” from our office. Careful placement and continued monitoring of the PRRs are what you are paying for.

We recommend that your child have preventive resins placed on the permanent molars as they come in. This is because we want to fill the grooves of these teeth with their larger biting surfaces. Occasionally we will do preventive resins on other teeth as needed. For example, we may choose to recommend a preventive resin on a tooth that has particularly deep grooves.

As always, please feel free to call our office if you have any questions. Thank you for allowing us to help you raise happy, healthy children.

Fondly,

Greg
