Not all the gaps can be reduced by composite bonding ..it depends from case to case....sometimes an orthodontic treatment may be necessary to do the needful ...hence without knowing the oral condition its difficult to give a proper assessment ....if a composite bonding is possible ...it would cost anywhere between 1500 to 4000 per tooth depending upon your location

Go for zirconia crowns instead of composite buildup.

Hi, costs depends upon the hospital setup. However dental college hospitals are cost effective...
