How would i get rid of saliva when i have whitening strips on?

Spit: You don't want to swallow much of the peroxide used in the whitening strips, so spit out your saliva for at least the first few minutes to prevent an upset stomach.

Spit!: Spit or if you're in the subway, you better expectorate into a cup.

Spit: Whitening strips and trays can cause some to over produce saliva. Best if you spit most of it out. If you swallow some it won't be harmful but you might not like the taste.

Swallow: You can swallow normally while you have the strips in.
