Tooth fillings can be performed using either direct or indirect methods.
In the direct method, the filling is applied directly in the patient’s mouth in a single visit. This process can be carried out under local anesthesia to ensure it is entirely pain-free. Typically, a composite resin is used as the filling material, which is cured in place using an LED light. The procedure can take anywhere from a few minutes to half an hour, depending on the size of the filling.
The indirect method follows a similar approach to the direct method, but the filling is fabricated outside the mouth. Initially, an impression of the prepared tooth is taken. This can be done using traditional impression materials or, alternatively, the tooth may be digitally scanned with an intraoral camera. This impression is then used to precisely create a permanent filling at a dental laboratory or via a milling machine, which is then securely cemented onto the tooth.
