Yes, tea can make teeth yellow over time. It contains tannins that stick to enamel and cause surface staining. Proper oral hygiene and professional cleaning can help reduce and prevent tea stains.
Tea is one of the most widely enjoyed drinks in the world. Many people ask whether tea can stain their teeth. The answer is yes — tea can cause yellowing over time. This happens due to natural compounds found in tea. The good news is that stains can often be prevented or reduced.
Why Does Tea Stain Teeth?
Tea contains tannins. Tannins are natural plant compounds that give tea its slightly bitter taste. When tannins mix with proteins in tooth enamel, they attach to the surface. Over time, this leads to yellow or dull staining. If staining becomes noticeable, professional Teeth Whitening in Aberdeen may help improve the appearance of discolouration caused by regular tea consumption.
