In many situations, CEREC same-day crowns have virtually replaced conventional crowns. Many dentists recommend CEREC crowns in every situation where a ceramic crown is appropriate.
Generally, these crowns are used to protect a tooth that has sustained extensive damage, either from advanced decay, internal treatment like a root canal or an injury.
Your dentist may recommend a conventional crown rather than a CEREC crown if you need an alloy dental appliance rather than a ceramic one. These alloy crowns are stronger and therefore are better suited for patients with bruxism.
