Chances are, you're not. Like many people, you likely apply far more toothpaste than necessary to your brush.
For thorough cleaning, a small dab is all you need.
TV commercials depict a full brush of toothpaste for two key reasons:
1. It looks appealing on screen.
2. It encourages using more product.
This overapplication adds up, leading to substantial annual savings for families.
Standard tubes cost around €1.30 (link to Amazon).
