Save Money on Toothpaste, Says Dental Hygienist.

A dental hygienist on TikTok has revealed that toothpaste doesn't actually clean teeth, but rather protects them from decay and acid erosion with fluoride. She advises using an electric toothbrush, floss, and interdental brushes to remove plaque build-up. The recommended amount of fluoride in toothpaste is 1,450 parts per million, and it's important not to rinse with water or mouthwash after brushing to allow the fluoride to work for 30 minutes. While some people may need specific toothpaste for sensitivity, expensive toothpaste is unnecessary for everyday use.
