You should wet your toothbrush before applying toothpaste

Okay, so I’ve always wet my toothbrush before putting toothpaste on it. Always. But lately, I’ve been seeing stuff online that says you shouldn’t. Like, it dilutes the toothpaste too much or something, and you don’t get the full benefit of the fluoride.

Is that true? Am I brushing wrong my whole life? What are the actual pros and cons of wetting your toothbrush beforehand? Like, does it really make a difference in how clean your teeth are? What about different types of toothpaste? Does it matter more or less with whitening toothpaste, or sensitive toothpaste, or kid’s toothpaste?

Also, I have a manual toothbrush. Does wetting make a difference vs. using an electric toothbrush? I’m really curious about the science behind it!

Answer

Yes, it’s generally recommended to wet your toothbrush before applying toothpaste. There are several reasons why this is considered a good practice:

• Softens the Bristles: Water softens the bristles of the toothbrush, making them less abrasive against your gums and teeth. This can be particularly helpful if you use a toothbrush with medium or firm bristles, reducing the risk of gum irritation or enamel wear.

• Activates the Toothpaste: A small amount of water can help to activate the ingredients in the toothpaste, such as fluoride, and allow them to spread more evenly throughout your mouth during brushing. Some people feel it helps create a better lather, although this is often a minor effect with modern toothpaste formulations.

• Improves Distribution: A wet toothbrush helps the toothpaste adhere better to the bristles and distribute more evenly across your teeth when you start brushing. It prevents the toothpaste from clumping in one area and ensures that all surfaces of your teeth are exposed to the beneficial ingredients.

• Reduces Toothpaste Waste: Wetting the toothbrush slightly can help prevent you from using too much toothpaste. It allows a pea-sized amount of toothpaste to cover the bristles more effectively, reducing waste.

• Personal Preference: While there are some benefits, it also often comes down to personal preference. Some people simply find the sensation of brushing with a wet toothbrush more comfortable.

It’s important to note that the amount of water needed is minimal. Just a quick rinse under the tap is usually sufficient. Soaking the toothbrush for a prolonged period is unnecessary and may not provide any additional benefits.

In summary, wetting your toothbrush before applying toothpaste is a simple yet effective practice that can contribute to better oral hygiene by softening the bristles, activating the toothpaste, improving distribution, and preventing waste.
