One question worth asking
Which teeth are being sealed today, and how long do these usually last?
Small preventive filling with sealant
D1352. A tiny filling in a groove that has started to decay, finished with a sealant over the top.
A sealant is a thin protective coating brushed into the grooves of a back tooth so food and bacteria cannot settle there. It is painless and takes a few minutes per tooth. Related codes cover repairing a sealant and a very small filling done with a sealant.
The tooth is cleaned and dried, the coating is flowed into the deep grooves on the chewing surface, and a light hardens it. Nothing is drilled and no numbing is used. Sealants are counted per tooth, and separate codes cover repairing one that has chipped and a very small filling placed with sealant material. Most plans file this as Preventive. What they actually pay varies by plan.
