Coffee is well-known for it’s teeth staining capabilities and for good reason: it’s both darkly coloured, thanks to a substance it contains called tannins, and it’s highly acidic. It’s dark colouring can transfer to teeth through prolonged and frequent exposure, giving teeth a yellow coloured stain. The acid in coffee eats away at tooth enamel if not properly and quickly removed. Once the enamel is weakened, the layer below the enamel, known as the dentin, and it’s more yellow colouring is exposed, giving teeth a stained look. So, when you catch up with someone over coffee during the holidays, consider adding milk to your java to tone down its staining affects or switch it out for another beverage entirely.
