@drnatphoon: If your teeth are turning yellow, it’s not always because of coffee. Tooth colour is influenced by what you consume, how your enamel changes, and even natural aging. Some stains sit on the surface and are easier to remove. Others sink deeper into the tooth structure and become much harder to treat over time. That’s why whitening doesn’t work the same for everyone. And why some cases need professional guidance before choosing a solution. If you’re unsure what’s causing your tooth stains or what your best options are, drop a comment or book a consultation through the link in my bio.
