When properly cared for, a dental crown should last about 10 years. They can last longer, but 10 years is about average. A crown will last a shorter period of time if not properly cared for. You should treat your crown as you would your normal teeth. Make sure and follow your dental hygiene routine of brushing, flossing, and rinsing. Make sure you do not chew on hard objects, as it could result in a cracked or broken crown. If a crown breaks, cracks, or falls off, please call our office immediately.
