If your teeth still appear yellow after whitening treatments, the cause may be deeper than surface stains. While whitening works well on many external stains, intrinsic discoloration caused by aging, medications, enamel thinning, or tooth trauma may not respond as effectively. Yellow stains often improve, but results vary depending on the type and depth of the discoloration. Professional evaluation can help determine whether additional whitening or alternative cosmetic treatments are needed.
