When a person has a moderate amount of dental decay, Dentists in Providence RI, may not be able to stabilize the tooth with a standard dental filling. However, the tooth does not need to be covered with a dental crown. Dental inlays and onlays are a middle ground. They are a custom filling made from porcelain, resin, or gold. They are sometimes referred to as indirect fillings or partial crowns. Because they use less material and the tooth does not need aggressive preparation, dental inlays and onlays are usually less expensive than dental crowns.
Once the dentist has cleaned the decay and older dental filling from the tooth, he determines if he will use an inlay or an onlay. An inlay is placed only in the middle of the tooth. An onlay is placed both in the center of the tooth and over the biting surface of the teeth. The dentist then takes an impression of the tooth, as well as the teeth above or below it. This is sent to a dental technician who will craft the actual inlay or onlay. If the inlay or onlay will be visible when the person speaks or smiles, resin or porcelain will be used to create it. These materials match the tooth material. If the inlay or onlay will fit in or over a back tooth, gold or another metal might be used. Metals are harder and are more able to stand up to rigorous chewing. While the patient is waiting for his inlay or onlay, he will wear a temporary crown to protect the tooth.
Before the dentist permanently cements the inlay or onlay in place, he carefully checks the fit. It might be necessary for him to change the top surface so the bite between upper and lower teeth is comfortable. Once the dentist is satisfied with the appearance and fit, he cements it into place. dentist in Providence RI, also give the patient instructions for proper care. If the patient brushes and flosses the teeth and has regular dental checkups, it increases the likelihood that the inlay or onlay will last for many years.
