Although the composite is already hardened, you should avoid chewing heavily on your new restorations for 24 hours. All tooth colored composite restorations will pick up some staining or discoloration over time – usually from tobacco, coffee or tea. The new generation of materials we have used on your teeth tend to stain much less than those previously used. Daily brushing and flossing will also help to decrease the staining tendency. Decay can still develop around the edges of bonded restorations, and your gums will be become inflamed if plaque is not removed daily. So once again we emphasize the value of meticulous daily oral hygiene so as to protect the investment you’ve made in your teeth. Normal brushing will not deteriorate or damage bonded restorations.
