Composite bonding can be done in one visit, and is the least expensive option to fix a tooth. While composite bonding will have to be redone at some point, it is a permanent material, so if you are happy with how the bonding looks you won't need to do anything else immediately. The price for a bonded filling is usually based on the number of surfaces. It could range from $160 to around $200, maybe a little more, in my practice. Fees vary depending on where you live. If the tooth has a large amount of decay or tooth structure missing, a crown or even a root canal with core build up and crown could be needed. There’s just no way to say without an exam and x-ray.
