Avoid eating and drinking until the numbness due to the anesthetic has subsided. If supervising children who have had a filling placed, take care that they do not bite their lips, inner cheeks, or tongue. Serious injury to their tissues may result.
It is normal to experience temporary sensitivity to cold, hot, and pressure following the placement of a filling, as well as some soreness to the gum tissues. This usually subsides in a few days. Such sensitivity is usually related to how extensive the decay or cavity is, and its proximity to the dental pulp or nerve. Usually, with greater or deeper decay, post operative sensitivity is magnified and requires a longer time period to subside.
In the days that follow the placement of a restoration, should the bite feel uneven (the teeth on one side seem to touch before the opposite side), or there appears to be some interference in biting, a fine adjustment of the new restoration may be required to balance the bite properly.
