Dental impressions on the margins of the tongue

A tongue with teeth marks at the edges. Dental impressions develop when the tongue becomes enlarged. They are a sign of insufficiency of the spleen’s yáng qì with exuberant dampness. Since the tongue body is usually pale, the term pale enlarged tongue with dental impressions (舌质淡胖有齿痕 shé zhí dàn pàng yǒu chǐ hén) is often encountered in the literature.
