What Happens When You Brush Your Teeth?

Brushing your teeth with a fluoride toothpaste is essential for:

Removing plaque and bacteria
Strengthening your enamel
Preventing tooth decay and gum disease

Fluoride is a key ingredient in most UK-recommended toothpastes because it helps remineralise enamel and protect against cavities. However, how you brush and what you do afterwards can affect how well the fluoride works.

Should You Rinse After Brushing?

No — you should not rinse your mouth with water immediately after brushing.

Why? Because rinsing washes away the fluoride left on your teeth by the toothpaste, reducing its protective effects.

Instead, you should spit out the excess toothpaste and leave the remaining thin layer on your teeth. This allows the fluoride to continue working long after you've finished brushing. Rinsing with water immediately after brushing dilutes and removes this fluoride, which can make your brushing less effective.

By not rinsing, you allow fluoride to remain on your teeth longer, giving it more time to strengthen the enamel and fight off decay.
