Do You Wet Toothpaste First?

Published in Oral Hygiene 2 mins read

Whether you wet your toothbrush before or after applying toothpaste is a matter of personal preference.

The Great Toothpaste Wetting Debate

There's no official recommendation from dental authorities like the ADA (American Dental Association) on whether to wet your toothpaste before brushing. The practice mainly boils down to individual preference and habit.

The Case For Wetting

Some individuals prefer wetting their toothbrush prior to applying toothpaste. Here are some reasons they may choose to do so:

  • Creates Lather: Wetting the bristles might help the toothpaste foam up more easily, giving the impression of more effective cleaning.
  • Softer Bristles: A wet brush can feel softer against the gums, which some find more comfortable, especially if they have sensitive gums.

The Case Against Wetting

  • Dilution: Wetting the toothpaste can dilute the concentration of fluoride, which is the primary agent for preventing cavities.
  • Unnecessary: The water from your saliva will mix with the toothpaste when you brush anyway, therefore making the water from the wet toothbrush unnecessary.

The Bottom Line

According to information available in the provided reference, wetting your toothbrush before brushing, and therefore wetting your toothpaste, is purely based on personal preference. There is no official guidance from dental authorities that dictates that it is either necessary or harmful to do so.
