Question about veneers...?

I am a dental istant and have been for ten years. It is really hard to tell without seeing your mouth but if you only need one veneer I dont see why the dentist is recommending 6 ,I am uming from canine to canine unless ther are some spaces or a severe shade difference in all of your teeth. If you are happy with your smile and just want the one veneer done and the dentist is just concerned about it matching properly the dentist can have you visit his/her dental lab that would be doing the veneer so that they can see your mouth and match a perfect shade. Please get a second opinion and don't be talked into anything you are not comfortable with. Good Luck!
