What's the optimal shape?

• 323 4y ago
  From my research the most important thing is for it to have soft bristles with round bristle heads (obviously you can't check bristle heads with your eyes, too small). Most you find in supermarkets have medium or hard bristles. The head shouldn't be too big, so that it can reach even in the back. Rubber inserts are not recommended, as they tend to irritate the gum. Typically the better ones look more plain - no multi colored bristles or spaceship looks. However, since this becomes more known, it becomes a marketing signal in itself - like "plain brown paper package" chocolate, etc.

    Are there any brands with these characteristics?
