In a recent test of supermarket own-brand toothpastes, a surprising discovery emerged: a 50p tube outperformed a £3 Colgate variant. The reviewer, long loyal to the Colgate brand, decided to investigate cheaper alternatives due to rising costs. This prompted a head-to-head comparison of the toothpaste from well-known UK supermarkets including Tesco, Morrisons, Asda, Sainsbury's, and Aldi, seeking to uncover if these budget options could offer a comparable quality.
