Tooth bonding is able to withstand everyday functions, allowing you to eat and live without worrying about your teeth. How long the bonding lasts can depend on many things, including how you care for your teeth. If you perform good home care and routine dental check-ups, dental bonding lasts for many years. If you are not consistent with home care or professional cleanings, the bonded teeth will not last as long as they could. Bonded teeth are susceptible to staining just like normal teeth, so you should avoid smoking and limit intake of wine, green tea, and other staining products.
