For repairing gaps in incisors, the fee varies depending on the method of repair. If a resin-based material is used to fill the gap, the basic cost is around 500-1000 RMB, depending on the size of the gap and the choice of resin-based material. If an aesthetic porcelain veneer is used for restoration, generally a veneer is around 4500 RMB. If the gap is large and 2-3 veneers are needed, the cost increases exponentially. If there is not only a gap but also a certain twist in the tooth and the direction of the twist needs to be changed, a certain number of teeth will need to be removed for the restoration of a full porcelain crown. Porcelain full crown restorations are charged per piece, depending on the porcelain crown material, from$900 a piece all the way to$6000 a piece, patients can choose according to their own consumption level and the degree of aesthetic requirements.
