FAQ

How long should the etchant stay on the tooth?
A common total-etch protocol is roughly 15-20 seconds on enamel and 10-15 seconds on dentin, but always follow the specific bonding system's instructions.

Why does the tooth need to stay moist after rinsing?
Over-drying etched dentin can collapse the collagen network and reduce bond strength, so most bonding systems call for a slightly moist ("wet bonding") surface.

Can Top Etchant be used before both composite and porcelain repairs?
This is a phosphoric acid gel for enamel/dentin; for porcelain surfaces, MedSTA separately stocks TOP Porcelain Etch, which uses hydrofluoric acid chemistry suited to ceramic.
