I drink minimum 2 cups black coffee daily for many years. Besides coffee, I also drink black herbal tea. As a result my teeth are stained heavily. I bought Oral Botanica Teeth Whitener to try to remove the yellow stains.
I followed the instructions to brush my teeth for 2 minutes twice a day using the teeth whitener for 5 days, followed by brushing with Oral Botanica Classic. Once a week, I use the teeth whitener to maintain white teeth. I followed this for 2 weeks.
The results are amazing, as the yellow stain was 75% gone within 5 days. I’m happy with the performance of the Oral Botanica Teeth Whitener, as it is effective and simple to use.
