Big tooth brushes prevent me from brushing my molars. There are many similar size Asian women and Latinas in the United States. I doubt my jaw size is smaller than theirs.
Every time I go to a dental appointment, the dentist tells me "Don't brush your teeth so hard. Your gum line is receding." I bought a tooth brush labeled "soft" at a drug store, but the bristles weren't really soft.
Americans are known to spend money on their teeth. I wonder why they are using tooth brushes which are so harsh on their teeth and gums.
For a while I was ordering particular expensive tooth brushes with soft bristles on-line, but soon I started to buy tooth brushes in bulk every time I went back Japan. There are a wider variety of tooth brushes in Japan at a good price, from big and stiff to small and soft.
However, it doesn't mean that Japan is the progressive country of oral hygiene. They spend less money on teeth than Americans, and fewer people floss every day.
