These are very effective in reaching all the corners and hidden areas in the mouth. I’ve tried these myself and can confirm of good quality and effectiveness.

I tend to not buy these for myself as they are just too big for my mouth they take up too much space otherwise good qaulity

Colgate Zig Zag medium toothbrush is a very affordable brush that cleans our teeth very good,we use the toothpaste and when this one goes on special we buy it.

This has to be the most comfortable and easy to use toothbrush created. It is gentle on gums yet cleans well.

Colgate Zig Zag Toothbrush Medium is my preferred Toothbrush. It is great to get right to the back teeth and has a tongue cleaner that I think is an important part to oral health. Always leaves my teeth feeling nice and clean.
