My dentist recommended toothpicks instead of floss. But the toothpicks hurt the corners of my mouth and create little wounds. Any tips on how to avoid that?

You may want to first find out if you have gum issues. But floss is much better overall. Use what you are comfortable with

If toothpicks hurt, then stop using them. Tell your dentist about the issue and have them recommend another, less painful option.

I’ve never heard of that. Did he say why toothpicks?? If it’s hurting you, stop. Good ole’ floss is proven to help I’m not sure if this is even a real question.

Have you thought about using floss stick like plackers?
They work well for me, and even have a toothpick part if you absolutely need it
