Dental crowns are essentially cases or covers placed on top of a severely weak or damaged tooth. You might be asked by your Keller dentist to opt for these devices if your teeth require some extra care and protection. These crowns act as a shield and protect your damaged teeth till they heal and gain strength. There are several cases when you might need to opt for dental crowns. Our dentists at ABC 123 Dental will give you a clear understanding of the situations where you must choose dental crowns.
