skin tags and tooth whitening

hello,
I have some skin tags (acrochordon) on my back that I would like to get removed. Has anyone had that done in Japan? also how do you say "skin tag" in Japanese?
Another thing I'd like to get done is tooth whitening.
Has anyone had that done ? If so, how was it?
thank you.

It's called "ryousei sen'i shu" (benign fibrous... something) - those harmless but somewhat bothersome small protrusions on the skin. In general, "warts" would be "ibo." The exact nature would have to be diagnosed by a dermatologist.

I've had a small wart on my face laser-removed by a dermatologist. I have seen teeth whitening advertised at my dentist but have not tried it.

thank you AK! I will try the new word!
