Microabrasion + Resin Infiltration

This approach is often used for superficial spots. If applicable, scaling and shade matching can be performed first. Typically, under strict isolation, a mild acid abrasive combined with micro-abrasion material is used to remove the stained surface layer, followed by the infiltration of low-viscosity resin into the enamel micropores and light curing to improve the optical appearance. Subsequently, polishing and evaluation of color and margins are performed. Early monitoring of sensitivity and color stability is essential, with additional infiltration or polishing as needed. The above is general health information, not medical advice; specific details depend on specialist evaluation and hospital protocols.
