Meanwhile, yellow teeth\u2014although not always unhealthy\u2014can sometimes signal underlying issues such as plaque buildup, tartar, or lifestyle habits. Importantly, tooth color is not purely cosmetic\u2014it can reflect oral health conditions that may require attention. <\/p>\n\n
What Causes Yellow Teeth? <\/h2>\n

Expert Insight by Dr. Pitchaya Vadhanakrai <\/h2>\n
After professional teeth whitening, the first 48\u201372 hours are crucial for maintaining results. During this period, the enamel is more receptive to staining, so it is important to avoid deeply pigmented foods and beverages such as coffee, tea, red wine, and certain sauces. Allowing time for the color to stabilize helps achieve a more even and longer-lasting result. For long-term maintenance, safe touch-up whitening can be performed annually under professional supervision to preserve brightness without compromising enamel health. <\/p>\n\n
