The Science Behind It
Rice flour acts as a mild abrasive that can help remove surface stains, similar to baking soda. Lemon juice contains citric acid, which may dissolve stains but can also erode enamel over time, increasing sensitivity and yellowing teeth. Olive oil may reduce bacteria slightly, but it won’t protect enamel from acid damage. Toothpaste adds fluoride, which strengthens teeth and helps prevent cavities.
Short-Term vs. Long-Term Effects
You might see a temporary brightness from physical scrubbing or acid-induced dehydration. However, repeated use of lemon juice with abrasives can permanently damage enamel, leading to more serious dental issues. Enamel, once lost, does not regenerate.
