POINT 3

Oral Environment Must Be Healthy!
pH Neutral Gargle

The acidity in the mouth dries out the oral cavity, creating an environment where bacteria can easily thrive.
This over-gargle was developed as a pH neutral formula, with a neutral concentration similar to saliva, to minimize irritation inside the mouth and create an environment that prevents tooth decay and enamel erosion.

*The above data is certified and measured by Allpassbio.

POINT 4

Goodbye to the Burning, Irritating Sensation in Your Nose
0% Alcohol

This product does not contain alcohol, which often causes dryness in the mouth and worsens bad breath. It does not cause dryness or irritation inside the mouth. Experience the refreshing new world of mouthwash without alcohol.

Q & A

The developer of Rebrush, Seongjun Go, speaks directly.

Q. Is it better to use the mouth rinse before or after brushing?

For cavity prevention, it is better to use it before brushing. If you rinse after brushing, the cavity-preventing ingredients on the toothpaste wash away. Regarding bad breath and gums, it is safe to use before or after brushing.

Q. Should I rinse my mouth with water after using the mouth rinse?

Rebrush concentrated mouth rinse contains zinc. Zinc captures bad breath gas, so it is recommended to rinse your mouth with water once or twice to remove the captured bad breath gas.

Q. The mouth rinse has a slight color. Why?

Because real fruit extracts and natural ingredients are used, it naturally has some coloring. It is free of artificial coloring, so you can use it with confidence.

Q. How many uses does one bottle provide?

One pump provides up to 100 uses. The concentration is 100 times that of regular mouth rinse, equivalent to about 2 liters of usual mouthwash volume.

Q. Can pregnant women and elderly people use this product?

This is a low-irritation product based on natural ingredients that exclude alcohol, coloring agents, and harmful substances, so it can be safely used by anyone.

Q. Can children use this product?

It is recommended for children 6 years old and above who can rinse their mouths on their own. It contains no fluoride or alcohol and uses a hypoallergenic formula, allowing children to safely start oral care.
