More foam does not mean more cleaning.
Foam is mainly produced by surfactants such as Sodium Lauryl Sulfate (SLS).
Their role is to spread toothpaste evenly and create that familiar “clean” sensation.
They do not mechanically remove dental biofilm.
Actual plaque removal depends on:
• Controlled mechanical movement of toothbrush bristles
• A full 2-minute brushing time
• Proper angulation along the gumline
• Mild abrasives that help disrupt biofilm and polish surface stains
• Fluoride that strengthens enamel and supports remineralization
Foam enhances perception.
Brushing technique determines effectiveness.
Excessive lather can create a false sense of completion — causing some people to stop too early, leaving biofilm along the gumline.
Clean teeth result from controlled mechanical disruption combined with protective chemistry — not from the amount of bubbles produced.
