If you prepare rice water specifically for oral use, make a fresh batch rather than keeping it at room temperature for extended periods. Fresh preparation reduces the risk of bacterial growth.
It is also important not to scrub your teeth with dry rice, rice powder, salt, baking soda, lemon juice, or other abrasive ingredients. Excessive abrasion can wear away enamel and make teeth appear more yellow because the naturally yellow dentin underneath becomes more visible.
For genuinely healthier-looking teeth, the most important habit remains regular brushing with fluoride toothpaste. Brush gently twice a day for approximately two minutes using a soft-bristled toothbrush. Pay attention to the gumline without pressing excessively hard.
Cleaning between the teeth is equally important. Floss or use another appropriate interdental cleaning method once a day to remove plaque from areas that a toothbrush cannot reach.
