Zirconia teeth should be brushed at least twice a day like normal teeth. Zirconium is a long-lasting material, but if oral hygiene is not taken care of, the natural teeth under the veneer can decay and because zirconium is a solid material, it may cause the decay to be noticed late. This can result in tooth loss.

Therefore, although zirconium crown is a very strong material, it must be brushed. Zirconium teeth is resistant to the formation of plaque and bacteria and therefore maintains both its color and strength even if it is not brushed.
