Powersmile whitens well and tastes great. Cleaning action makes dental checkups easy. One downside is that powersmile contains no fluoride.
The flavor is something to note with the whitening capabilities and also value for money. I like pronamel better than other toothpastes as it dissolves better in the mouth. The enamel builder is gentle on the mouth, does its job and tastes good too.
Potassium nitrate component seems to particularly work for soothing nerve pain.
Sensodyne has been recommended by my dentist, have used it fir years. My dentist’s office always compliments my at home hygiene. It is so gentile and i love the feel of my teeth after brushing them.
Sensodyne is more difficult to rinse than colgate competitor. They imitate packaging of the brand name but then add cheap quality contents.
