Teeth whitening

I saw it somewhere before.

For teeth whitening, use powdered dried lettuce.

It is effective to brush with toothpaste when brushing your teeth.

They said they did it.

Some components in lettuce on the surface of the teeth

It works to produce a whitening effect.

But whether this is really feasible or not

I'm not sure.

I want to try it, but I can do it continuously in the long run.

I haven't tried because I wasn't sure if it would be there.

It might just be that I am the only one who misunderstands.

I suddenly remembered, so I'm writing it down.
