Although dental crowns and dental fillings are both used to restore decayed or broken teeth, the way they treat decay is different. Dental fillings are used to fill holes in the tooth left by decay. On the other hand, a full coverage dental crown is generally used to repair larger decay than dental fillings. Here are a few more reasons Dr. Singla and his team at Singla Dental may recommend a dental crown.
Following a Root Canal
Once a tooth has had endodontic therapy, it is no longer vital, meaning the tooth is dead and no longer receives blood or nutrients from the body. In this case, the enamel becomes brittle and can wear down from everyday use. To repair larger decay, especially from a root canal or extraction, Dr. Singla may use a dental crown. Putting a dental crown over a tooth with a root canal can allow it to continue functioning as normal for many more years to come. The dental crown protects the tooth underneath from infection and decay.
Severe Decay or Fractures
To fill a tooth, the tooth needs enough structure to hold a restoration appliance without breaking. If you are repairing large decay, the filling may fall out or easily disassociated from the tooth. To repair larger decay, Dr. Singla may cover the tooth with a dental crown instead of using a dental filling. Dental crowns extend over the entire surface of the visible gumline. Consequently, covering a tooth to repair larger decay distributes pressure across its surface to maintain natural tooth function.
Replacing an Old, Large Filling
If you have a very large, old metal filling, it is only a matter of time before it starts to leak or give out. Unfortunately, once you remove a filling to repair larger decay, you also have to re-prep the area around it to re-fill the tooth. To repair larger decay, the tooth may, once again, not have enough structure to support the filling. The next step would be to put a dental crown on the tooth.
Delaying your dental crown can put your tooth at risk for continued fracture, decay, or wear to the point where it is no longer restorable. Many times, to repair larger decay, Dr. Singla recommends dental crowns to his patients.
