More than foam
Cleaning particles help remove deposits and external stains. More foam or a stronger flavour does not automatically mean better cleaning.
Different ingredients, different aims
Fluoride supports cavity prevention. Other ingredients may target sensitive exposed dentine, for example; a label cannot identify the cause of symptoms.
Need before marketing
Children, exposed root surfaces and sensitive teeth may need a tailored choice. Toothpaste cannot simply regrow missing tooth structure or fill a cavity.

Often confused
Cleaning or repairing?
Toothpaste supports cleaning and, depending on its ingredients, protection. It does not automatically repair an existing structural defect.
Quick answers
Is whitening toothpaste the same as bleaching?
No. It often mainly removes external stains. Lightening the tooth substance itself is a different procedure.
Is fluoride-free always better?
No. Fluoride toothpaste is an established cavity-prevention measure, used in an age-appropriate way.
How much should children use?
The amount and fluoride concentration depend on age and guidance. Do not automatically use an adult-sized amount.
