Can I use teeth whitening strips every day?
Yes, many whitening strips are designed for daily use over a short period, typically 7–14 days.

Does baking soda help with teeth whitening?

Using it too aggressively or too often can wear down enamel over time. - Baking soda can help remove surface stains but does not lighten natural tooth color. - Overuse can damage enamel; limit to once a week. - Professional whitening is more effective for significant color change.

It is strongly recommended to avoid smoking for at least 48–72 hours after teeth whitening. Tobacco contains tar and nicotine that can immediately stain freshly whitened enamel, and the heat and chemicals can irritate sensitive teeth and gums, delaying healing.
Why do my teeth look more yellow after whitening strips?
It is common for teeth to appear temporarily more yellow or blotchy immediately after using whitening strips.
