Based on a recent study, Dr. Gordon Christensen gives advice on what to tell patients with ceramic crowns about acidic beverages.

By Gordon J. Christensen, DDS, MSD, PhD

Every dentist knows that patients drink and eat acidic foods and beverages frequently on a daily basis. It is well known that these beverages and foods dissolve tooth structure. It has been assumed that the same agents also negatively influence ceramic surfaces.

This study showed that agents such as pineapple juice and green mango juice leached various ions from the surfaces of VITA VMK 95, Vitadur Alpha, IPS Empress Esthetic, and IPS e.max Ceram. The specimens were analyzed under electron microscope. (Kukiattrakoon B, et al. The effect of acidic agents on surface ion leaching and surface characteristics of dental porcelains. J Prosthet Dent 2010; 103:148-162.)

Dr. Gordon Christensen comments:It is advisable to tell patients with ceramic crowns to limit their use of acidic beverages, drink them through a straw when possible, rinse after consumption, and consume them all at once rather than slowly.
