A. Dental implants are only used when teeth are missing, so you shouldnt be considering this as an option at this point!!! The upside down V is more commonly caused through erosion. When you drink lots of fizzy/acidic drinks- acid can wear awat your teeth- often into a V shape. This can be corrected with veneers/composite build ups, but idealy you need to reconside your diet habit and limit your acidic foods/drinks to mealtimes. Costs may vary- composites can cost approx £150+ per tooth. Porcelain veneers may cost £500 + per tooth
