Problems solved by technology

However, the conventional toothbrush still has following drawbacks.
If the conventional toothbrush is provided with hard brush hairs, the hard brush hairs easily injure the gum of the user.

Therefore, the conventional toothbrush does not have enough cleaning effect and causes some dregs remaining in the mouth to incur dental disease.
