I once asked the dentist why are there so many different toothbrush head shapes, with the bristles at all kind of angles and patterns, rubber inserts and so one. Surely by now we know what's the optimal shape?
And the answer was that yes, the optimal head shape is known, but since it's not that consequential this is not regulated as other medical stuff and basically everyone does weird shapes just for marketing and differentiation purposes (like colored specks in powder detergent which do nothing)

- 323 5y agoFrom 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.
