As with any medical procedure involving anesthesia or incisions into the tissue, there can always be a risk; however, most patients experience little or no side effects when dental veneers are placed over their natural teeth. Possible risks include allergic reaction to materials used during treatment (i.e., porcelain), sensitivity due to enamel removal during preparation, and gum irritation resulting from incorrect placement of adhesives/bonding agents; however, these issues can usually be prevented with careful planning by both patient and dentist before the beginning treatment protocol.
