My temporary filling came out and it is the weekend.

A temporary filling coming out is usually not an emergency, so you can come in as soon as possible after the weekend. Until then, 1) fill the hole with a temporary filling material from a pharmacy, 2) chew on the opposite side, and 3) avoid hot, cold, and sticky foods such as caramel and gum. If the space stays open for a long time, bacteria can get in and treatment may have to be redone. However, if you have severe pain, swelling, or fever, find a dental clinic or hospital offering emergency care even on the weekend.
