I tried Dr. Oral Medicated 3D Whitening Paste. It contains 33% of Bio 3D Apatite, a proprietary eggshell-derived apatite. This quasi-drug toothpaste is recommended for those who want to whiten their teeth, prevent cavities and periodontal disease, or are concerned about bad breath. Bio 3D Apatite was developed for thorough whitening of teeth. It apparently reaches the backs and innermost layers of the teeth, even between the teeth and gums, for three-dimensional whitening. I tried it right away. I was excited because it's Dr. Oral's first quasi-drug. The white cream foams, but not too much, so I was able to brush thoroughly. The Prime Mint flavor is refreshing and cool, without being too spicy. The refreshing mint flavor is refreshing and pleasant. I think my child, who doesn't like spicy toothpaste, could use it. It's also great that it's colorant-free, alcohol-free, paraben-free, mineral oil-free, and synthetic fragrance-free. If you're interested, check it out. * Hydroxyapatite (cleaning agent)
