Although it’s true that dental bonding can produce an absolutely beautiful smile, it does have some limitations that you should be aware of when deciding whether or not this dental service is right for you. The bonding material itself doesn’t last forever and needs to be replaced every few years. Teeth that have been bonded can still be stained by certain foods, drinks and habits – like smoking or drinking too much coffee or red wine, for example. Bonding material can also be damaged, so you should avoid chewing anything hard, such as ice or hard candy.
