Preventive Resin Restoration (PRR or Sealant)

A Preventive Resin Restoration (PRR) is a gentle, protective coating that we apply to the chewing surfaces of molars, premolars, and other areas with deep grooves—also known as pits and fissures. Since more than 75% of dental decay starts in these hard-to-reach spots, PRRs offer an easy way to keep those vulnerable areas cleaner and better protected.

By sealing the deep grooves, a PRR creates a smoother surface that’s easier to brush and less likely to trap food or bacteria. It’s a simple but powerful way to help prevent cavities and keep your smile healthy.

While PRRs can last for many years, we’ll keep an eye on them during your regular visits to make sure they’re holding up well and giving your teeth the protection they deserve.

Reasons for Preventive Resin Restoration:

• Children and teenagers – As soon as the six-year molars (the first permanent back teeth) appear or any time throughout the cavity prone years of 6-16, protecting your teeth from cavities, particular for little ones who may not be doing a great job of brushing.

• Adults – Tooth surfaces without decay that have deep grooves or depressions.

• Baby teeth – Occasionally done if teeth have deep grooves or depressions and child is cavity prone.

What do Preventive Resin Restorations involve?

PRRs are easily applied by your dentist and the process takes only a couple of minutes per tooth.

The teeth to be sealed are thoroughly cleaned and then surrounded with cotton to keep the area dry.  A special solution is applied to the enamel surface to help the sealant bond to the teeth.  The teeth are then rinsed and dried.  Resin material is carefully painted onto the enamel surface to cover the deep grooves or depressions.  Depending on the type of resin used, the material will either harden automatically or with a special curing light.

Proper home care, a balanced diet, and regular dental visits will aid in the life of your new sealants.
