New Delhi (Desk), August 28, 2025 : Actor Nia Sharma recently shared a viral home teeth-whitening hack on Instagram, brushing her teeth with a mixture of baking soda, salt, coconut oil, and toothpaste. While she presented the experiment with her usual humor—joking, “Khoon woon aa gaya toh abhi bata dungi”—dental experts caution against such DIY trends, citing potential risks to oral health.

The combination of baking soda and salt is commonly promoted for removing stains. Baking soda, a mild abrasive, can temporarily brighten teeth by scrubbing away surface discoloration. Salt, similarly abrasive, may have a minor cleaning effect. Coconut oil, often used in oil-pulling remedies, is believed to support gum health. However, experts warn that the abrasiveness of baking soda and salt comes at a significant cost.

Dr Niyati Arora, BDS, MDS, a prosthodontist at Krown Hub Dental, explains, “Baking soda is effective at removing stains, but it can erode the protective outer layer of enamel. Over time, this exposes the underlying dentin, which has a yellowish tint, making teeth appear permanently yellow and sensitive to hot and cold.” Regular use of such abrasive ingredients can wear down enamel, leaving teeth vulnerable to cavities, staining, and long-term damage.

Enamel is crucial not only for aesthetics but also for protecting teeth from sensitivity and decay. Dr Arora emphasizes that once enamel is damaged, it does not regenerate, making protective care essential. While DIY hacks may offer quick results, they often compromise this natural defense, which is why dental professionals advise caution.

For those seeking whiter teeth without harming enamel, Dr Arora recommends safer alternatives such as products containing hydrogen peroxide. These work by oxidizing yellow and brown stains on the tooth surface. In professional dental settings, hydrogen peroxide treatments are carefully administered to protect gums and the tongue from corrosive effects. Over-the-counter whitening products can also be used, though results may take multiple applications and require patience. Improper or unregulated use can carry risks similar to abrasive DIY remedies.

Experts suggest consulting a dentist before trying any teeth-whitening method, especially if it involves abrasive or chemical ingredients. While viral hacks are tempting, understanding the science behind oral health ensures that the pursuit of brighter teeth does not lead to long-term problems such as enamel erosion, sensitivity, or permanent discoloration.

Nia Sharma’s experiment highlights the popularity of social media trends in beauty and wellness, but it also underscores the need for expert guidance. Using home remedies without proper knowledge can inadvertently harm teeth rather than improve them.

Ultimately, temporary whitening from abrasive ingredients may provide short-term satisfaction, but professional advice and safer methods are key to maintaining healthy, strong, and naturally white teeth over time.
