One product that can help with tongue brightening is GuruNanda Advanced Oil Pulling with Tongue Scraper Inside The Box. It contains coconut oil and vitamin E as active ingredients, and claims to freshen, detox, whiten, clean, and eliminate bad breath. However, it is important to note that a white tongue can be a sign of trapped bacteria, debris, or dead cells on the tongues surface, and can be caused by poor oral hygiene, smoking, or chewing tobacco. To maintain good oral hygiene, it is recommended to get regular dental checkups and to control the production of dental plaque, which is formed by microbial action. Other products that can help with oral care include Cavex Fresh4Sure Tongue Gel, which reduces bacterial growth and preserves "good" bacteria that promote oral health, and Colgate® IN Whitening Solutions, which can help with tongue bacteria. It is important to read the ingredients and instructions of any oral care product before use, and to consult a healthcare provider if there are any concerns.
