How to make a toothpaste at home
Avoid swallowing the toothpaste
Warning! Only under adults supervision.
Reagents and equipment:
- 50 g of baking soda;
- 20 ml of glycerin;
- 15 ml 3% hydrogen peroxide solution;
- 15 ml of water;
- 1 drop of mint flavoring;

Particles of baking soda act as an abrasive and remove plaque, and the glycerin makes the mixture paste-like. Hydrogen peroxide kills bacteria and eliminates bad breath. The mint flavoring gives the paste a pleasant taste.
