Bonded teeth should be brushed and flossed daily, and professionally cleaned here at the dental office twice per year, just the same as the rest of your teeth. The most important thing to keep in mind about caring for your bonded tooth is that composite resin can absorb stain, just as natural teeth can. Therefore, you will want to avoid smoking, red wine, coffee and tea to the extent possible. Also, while composite can darken, it cannot be lightened. So if you are thinking about having your teeth whitened, it should be done before your tooth is bonded so that a composite shade can be selected to match the lighter color of your whitened teeth. If you whiten your teeth after bonding, the bonded tooth may not match all the rest. Finally, try not to bite your nails, hold writing implements in your mouth, or use your teeth in other ways that could put excessive force on the bonding material and chip it. With proper care, a bonded tooth should stay beautiful for 3 to 10 years.
