When does dental decay require a crown instead of a “filling”? This is a question on many patients’ minds as they sit in the dental chair while the dentist is doing his check-up.
The answer isn’t simple – it is a judgment call on the part of the dentist.
Dental fillings are perfect for small cavities. Today these fillings are almost always done with a tooth colored (composite) material so that the repair isn’t visible to non-professionals.
When the destruction (cavity/caries) of a single tooth is too wide or covers too many surfaces the dentist makes the judgment call to recommend a crown. Large fillings put the tooth structure at risk. When the patient bites, a large filling will act as a wedge and can split the tooth, causing a multitude of problems. The crown actually serves as protection to the tooth. It is a little “cap” that fits over the prepared tooth and is ultimately bonded onto the tooth.
The crown is usually fabricated in a dental lab, although some dentists have a machine in the office to make the crown. If it is a lab prepared crown, a second office visit, which is shorter and included in the crown fee, is necessary for placement. If your dentist fabricates the crown in his office, only one visit is required.
At your exam, your dentist may identify old fillings that are beginning to break down. These fillings can be likened to “landmines” in your mouth – you don’t know when they are going to explode (break the tooth and/or become infected)! It is usually prudent to deal with them as soon as possible, to minimize the stress, problems and expense.
Whether it requires a crown or a filling, a skilled dentist and his team can resolve a dental problem and help you bring your smile back to life!
