Over time some of our teeth with old fillings will become susceptible to problems such as decay and cracks. Large old fillings, especially on the back molars, in some cases fillings or bonding will not be sufficient. The back molars should be strong enough to withstand the hard pressures of chewing. That is why crowns are necessary.
A computerized assisted Zirconia crown is created by the laboratory to maintain a natural appearance and be extremely strong. A wide range of shades are used to match the existing color of your teeth.
