The main reason lies in the contenttannin(tannins) in green tea. Tannins are natural plant-based polyphenolic compounds that give tea its slightly astringent taste. These compounds easily adhere to tooth enamel. When tannins bind to natural proteins on the tooth surface, over time, thin stains (stain) which causes the color of the teeth to appear increasingly yellowish or dull.
Besides tannins, green tea also contains a certain acidity level (pH) that can erode the thin layer of enamel if consumed excessively. When enamel is eroded, the layer underneath—called...dentinand is basically yellowish in color—it will be more visible on the surface.
What Drinks Make Teeth Yellow?
Besides green tea, there are various other popular beverages that are the main culprits behind tooth discoloration. If you want to maintain a bright, white smile, it's best to limit or be mindful of your consumption of the following beverages:
- Coffee:Contains high tannins and chromogens which easily stick to tooth enamel.
- Black Tea:It has a much higher concentration of tannins than green tea, so its effects on tooth stains are more quickly visible.
- Carbonated Drinks / Soda:Besides containing concentrated artificial coloring, soda is rich in acid which can significantly erode the protective layer of teeth.
- Red wine (Red Wine):The combination of concentrated chromogens, tannins, and acidic properties makes this drink very aggressive in changing tooth color.

- Enamel Erosion (Acid Erosion): Brushing teeth directConsuming acidic foods or drinks is actually dangerous. Acid softens enamel; brushing immediately will erode and thin the enamel.
- Deep Stain (Intrinsic Stain):Use of certain medications during childhood (such as antibiotics)tetracycline), excessive fluoride consumption (fluorosis), or physical trauma to the teeth can cause the yellow color to originate from within the tooth structure, rather than just surface stains.
- Smoking Habit:Nicotine and tar in cigarettes stick to teeth very quickly and are difficult to remove with just regular toothpaste.
