My teeth keep getting more yellow even though I brush twice a day. Why won’t they stay white?

Hormonal changes, such as those occurring during pregnancy or menopause, can affect oral health and potentially contribute to discoloration. While these factors are largely beyond control, maintaining good oral hygiene can help mitigate their effects.

12. Professional Whitening vs. DIY Kits: Why Results Fade and What’s Safe
Professional whitening treatments offer more dramatic and longer-lasting results compared to over-the-counter kits because they use higher concentrations of bleaching agents. However, these results are not permanent and can fade over time, especially with exposure to staining substances.
DIY kits are often less effective and may cause sensitivity if misused. It’s important to follow instructions carefully and consult with a dentist to choose safe and effective whitening options.

13. Realistic Expectations: How White Can Your Teeth Actually Get?
Understanding that teeth have a natural limit to how white they can get is essential. Factors such as the natural color of your dentin and the thickness of your enamel set boundaries.

While whitening treatments can significantly enhance the brightness of your smile, achieving Hollywood-level whiteness may not be realistic for everyone. Setting achievable goals based on your natural tooth color can lead to greater satisfaction with whitening results.
