The exchangeability of the toothbrush proper enables anyone to; easily find the desired shape and hardness of the bristles and, when the bristles are worn out, it isV not necessary to buy a new handle portion.

1. A toothbrush, comprising in combination a tubular handle, constructed as paste container,

a brush body with bunches of bristles on the end of said handle and having a discharge channel with branch slots terminating between said bunches of bristles, and rubber tongue shaped mouthpieces of rectangular cross section projecting from said branch slots in transverse direction over the entire width of the brush body and having walls tapering and consequently more flexible towards their outer end.

2. A toothbrush, comprising in combination a tubular handle, constructed as paste container, a brush body with bunches of bristles on the end of said handle and having a discharge channel with transverse branch slots terminating between said bunches of bristles, and rubber tongue shaped mouthpieces extending one from each of said branch slots and each having a discharge slot situated between inclined longitudinal walls contacting with their inner sides at the outer ends and successively diverging towards their inner ends.
