No, composite veneers, when installed by an experienced practitioner like Dr. Katz or Dr. Glazarov, are safe and effective. The mistaken belief that veneers can hurt your teeth or damage your oral health may stem from individuals who had either composite or porcelain veneers incorrectly applied. This can occur when the dentist takes out too much tooth enamel, possibly making the teeth in question more vulnerable to damage or decay.
