I am a 49 year old woman and have 2 crowns and 2 veneers for my four front teeth. The two front teeth are veneers and the two incisors are crowns. My two front teeth are old luminaire veneers and I want them replaced but I was told that I would have to replace all four teeth to get the best results. I would like to get the 2 front replaced with crowns and I would like to know the cost. I am visiting Istanbul in August and hoping to do the procedure then
