I Have a Small Chip on the Bottom of my Front Porcelain Veneer. Will It Have to Be Replaced? (photo)

Is normally needed when a veneer chips. If you don't mind how it looks, it might be able to be smoothed, but repairs are not long lasting. 

There is a small chance that you could have it smoothed without it being noticeable.  It could cause a difference in length between the front two teeth though.  If this occurs, replacement would be your only other option.  

The chip is hardly noticeable. I would polish it and match the shape of the neighboring front tooth. I would advise the patient that if it chips more, we can still fix it probably without replacing the whole veneer. By the way, you have beautiful teeth!
