Review on Pack of 6 COLGATE 🪥 Extra Clean Toothbrushes, Full Head, FIRM #40 by Heather Shaw

Finally found hard toothbrushes. Medium and soft leave my teeth less clean. Since I brushed with this hard brush, I no longer have tartar. I would have to brush my teeth with a medium brush after brushing, but this stiff brush does an excellent job of removing tartar and getting below the fitness line. My teeth seem so clean and my gums are healthy. I believe dentists have recommended light to medium job security so they can bill for their dental hygienists cleaning every two years, but that's just my opinion.
