I am getting more confident with my teeth and smile since I started using Biomin C toothpaste. I am in my 50’s and I have had white spots on my two front teeth since childhood and I was also noticing a darkened tooth and small black spots in the corners of my bottom teeth from using Charcoal toothpaste. It’s been nearly two months now and I have just noticed a significant change; the enamel really does look thicker, feels smoother and is whiter, and I can’t see the white spots. The darker tooth is getting lighter too so I’m 100 percent happy with the science behind Biomin and the improvements so far. It does take a little getting used to spitting out the toothpaste with no rinsing but I brush my teeth as normal then brush with Biomin toothpaste in the morning and evening. Will definitely continue to use Biomin. Fiona C
