Can bonding be used to make teeth larger/bigger? (photos)

Veneers are stronger than bonding, meaning it can withstand the forces of your bite, much better.Veneers are also more color stable, due to porcelain, or lab processed composite.If you want to lengthen your teeth, depending on your bite, Dental bonding can work, but again depends on your bite (occlusion).Looking at your before picture, there is going to be some teeth preparation needed even if you want to do bonding, in which with that in mind, due to the looks of your bitye, I recommend a stronger material to be used at the incisal edges of your teeth .Again tooth bonding will work great for the width of your teeth, but at the edge of your teeth prognosis is not as strong as porcelain veneers.Best of Luck.

Your one photo does not give enough info about your present post-op bite (occlusion). If in fact you are now upon closure ( as in the photo) almost biting edge to edge against your upper and lower incisors....then bonding or laminates would interfere with your closure and function.  In short they would either break or harm your bite.  Send more photos with your back molars in full contact and we may be able to re-assess.  But at present ( if the photo shows your new bite) the only way to lengthen your teeth is by altering the gum-line...not adding to the edges.
