Dental crowns are a go-to solution in restorative dentistry because they are versatile and provide many benefits. A crown is intended to serve as a long-term method of repairing a damaged tooth or protecting a weakened one from breaking. However, a restoration can be used along with other procedures, like root canal therapy. No matter the reason, a crown can last for a decade or longer before needing to be replaced, but many things will affect its lifespan. Here’s how long you can expect your crown to last and what you can do to maximize your investment.
