No hard, chewy, or sticky foods on the same side as the temporary is. Avoid: gum, caramels, carrots, apples, gummy bears, jelly ranchers, etc. If you have a temporary in the front, do not bite into any foods. Break or cut your food into chewable pieces.
Brushing and flossing:Brush area well and keep the tooth as clean as normal. By not keeping the tooth clean will cause gum disease and bleeding. Rinse with warm, salt water if your gums are sore. When flossing, pop the floss through the area , clean in-between, and then slide through the side. Don't pop the floss back out as this may dislodge your temporary crown. You can also tie a knot in the floss and slide the floss through the side to help dislodge any stubborn food particles.
