4 different “whitening” formulas
Charcoal toothpaste
Toothpaste for bad breath
Toothpaste for sensitive teeth
Toothpaste + mouthwash combined
Deep clean toothpaste
Plaque-shield toothpaste
Overnight toothpaste that you use before going to bed
I wondered how hard it’d be to make a toothpaste that does all of those things?? Maybe there’s a covenant against it. I read about with old light bulbs, where there was a gentleman’s agreement to keep sales strong, so despite it being easily doable anyone who made a light bulb that lasted more than 1,000 hours was bullied out of the industry
In the end I bought the basic toothpaste on the bottom shelf for 99p
