Full coverage crowns are usually recommended when a tooth is too weak, damaged, or too worn to be repaired with a simple filling. Full coverage crowns cover the visible part of the tooth and help protect it from breaking down further. If your dentist has told you that you need a crown, there is usually a specific reason behind it. Read on to learn more about when a full coverage crown may be needed.
What is a full coverage crown?
A full coverage crown is a tooth-shaped cover that fits over the entire visible portion of a tooth. It restores the tooth’s shape and helps it handle normal chewing again. Crowns are used when the tooth still has enough structure to save, but not enough to stay strong on its own. The goal of a full coverage crown is to keep the tooth in place and prevent more serious problems later.
Why does someone need a full coverage crown?
There are several reasons why someone might need a full coverage crown. The most common are:
- Severe decay or damage: One of the main indications for a full coverage crown is extensive decay. A small cavity can usually be treated with a filling. When decay is larger, however, too much of the tooth may be missing for a filling to work well.
- Cracked or broken teeth: Full coverage crowns are also used for a cracked or broken tooth. Cracks can be difficult because they may continue to spread when you bite or chew. This is especially true for molars, since they take on more pressure.
- After a root canal: Many teeth need crowns after root canal treatment. A root canal removes infected or damaged tissue from inside the tooth. This can save the tooth, but the tooth may be weaker afterward. Back teeth are more likely to need crowns after root canals because they do most of the chewing. Without the added support, the tooth may be more likely to fracture.
- Large fillings: Teeth with large fillings may also need crowns. When a filling takes up a large portion of the tooth, the remaining tooth structure can become thin or weak. Over time, the tooth may crack around the filling.
- Worn teeth: Some teeth become worn down from grinding, clenching, acid wear, or years of normal use. When teeth are severely worn, they may become shorter, weaker, or more sensitive.
- Dental bridges: Full coverage crowns are also used with dental bridges. A bridge replaces a missing tooth by using the teeth on each side of the gap for support. Those support teeth are covered with crowns, and the replacement tooth is attached between them.
What’s the bottom line?
Full coverage crowns are a common dental appliance that is used when a tooth needs stronger protection than a filling can provide. It may be recommended for decay, cracks, root canals, large fillings, worn teeth, or dental bridges. If your dentist recommends one, ask what problem the crown is meant to solve and what material is best for your tooth.
