Which of the following is NOT a method of dental restoration?

The process of dental restoration involves repairing or replacing damaged or missing teeth to restore function and aesthetics. Typically, methods of dental restoration include fillings, crowns, and bridges. Each of these methods serves to address specific dental issues, such as cavities, severe decay, or tooth loss, by providing materials or structures that rehabilitate the natural tooth structure.

Fillings are used to repair cavities by filling in the decayed portion of a tooth. Crowns are caps that cover damaged teeth, providing strength and improving appearance. Bridges are applied to replace one or more missing teeth by anchoring to adjacent teeth.

Extraction, on the other hand, involves removing a tooth rather than restoring it. This procedure may be necessary due to extensive decay, infection, or orthodontic reasons, but it does not contribute to the restoration of dental function or aesthetics. Thus, extraction does not fit within the scope of dental restoration methods.
