It depends on their location in the mouth and their relationship to each other. In some cases, we can spend almost as much time numbing the patient as we do the fillings.

If they are not large (for example, Class I or Class II, i.e., one or two surfaces) and are in the same quadrant/lower side, the entire appointment could take about 30 minutes. If they are spread across the upper and lower parts, and the right and left sides, more injections will be required, and therefore the appointment will be longer.
