Hello Sir, Smile makeover is done to improve your smile as the name state by improving your teeth size,shape ,colour or alignment. It can be done either with filling like composite or with crown (caps) , bridge or veneers

This would be best answered by a cosmetic dentist.

A smile makeover is a process in which the shape, colour, size or all of these can be changed with regards to the teeth. It is purely for cosmetic purposes. It can make a drastic difference in appearance. If done with ceramic veneers or crown, it’s permanent but can be done temporarily in composite also, though, even composite can eventually be used as a permanent material.
