Newer dental fillings include ceramic and plastic compounds that mimic the appearance of natural teeth. These compounds, often called composite resins, are usually used on the front teeth where a natural appearance is important, as well as on the back teeth depending on the location and extent of the tooth decay.
Direct or Indirect fillings?
- Direct fillings are fillings placed immediately into a prepared cavity in a single visit. They include glass ionomers, resin ionomers, and composite (resin) fillings. The dentist prepares the tooth, places the filling and adjusts it in just one appointment.
- Indirect fillings generally require two or more visits. During the first visit, the dentist prepares the tooth and makes an impression of the area to be restored. The dentist then places a temporary covering over the prepared tooth. The impression is sent to a dental laboratory that creates the dental restoration. At the next appointment, the dentist cements the restoration into the prepared cavity and adjusts it as needed.
