It is a good idea to avoid eating and drinking for the first few hours after your treatment because your mouth is still likely to be a bit numb from the local anaesthetic. After that you’ll be able to eat as normal but should try to avoid very hard or sticky foods. Your crowns and bridges will be fixed in your mouth so it’s important to brush and floss them just as you would your natural teeth. Although porcelain restorations are good at resisting staining, their composite equivalents are likely to experience some discolouration over time, so greater care should be taken over consuming some darker foods and drinks.
