Teeth erosion, also known as dental erosion, is the gradual loss of tooth enamel due to the action of acids on the teeth. Tooth enamel is the hard, protective outer layer of the teeth, and when it wears away, it can cause a range of dental problems, including tooth sensitivity, cavities, and even result in tooth loss.

Acidic foods can have a significant impact on the health of your teeth, especially if consumed frequently or in large quantities. The acid in these foods can erode the enamel on your teeth, leading to tooth decay, sensitivity, and other dental problems.

Teeth may become more yellow as you get older, especially when the tooth enamel wears away from chewing and after exposure to acids from food and drink. Teeth turn yellow as the enamel thins with age, but may become a greyish shade when mixed with food stains.
