Dentists use crowns and fillings to repair decayed or damaged teeth. Fillings are generally used to repair small areas of damage while a crown is more appropriate for repairing a tooth with more extensive damage. Fillings are less expensive than crowns and in a borderline case, your dentist may give you the option of choosing a between ac crown or a filling to repair a damaged tooth. Understanding the difference between the two types of restorations can help you decide which is the better option for you.
A filling is commonly used to repair a tooth with a relatively small area damaged by tooth decay. Your dentist will remove the decayed portion of the tooth while preserving as much of the natural tooth as possible. The area will then be filled with either a silver colored filling material called amalgam, or a type of high-tech plastic tooth colored material called a composite.
If a large amount of the tooth has to be removed, the tooth becomes weak and there is the chance that the tooth with crack after it has been filled. In these cases, a crown is a better alternative. A crown is like an upside down cup placed over the natural tooth. A crown is shaped to look like a tooth and is made of a metal base covered in porcelain or all porcelain material.
A crown is more expensive than a filling, but it provides much better protection for the tooth. A filling typically lasts ten to fifteen years and a large filling could cause the tooth to crack even sooner, but a properly placed crown could last a lifetime without any problems. Filling a large cavity may save you money in the short run, but there is a high likelihood that a large filling will eventually need to be replaced with a crown.
