How to change period in title to hyphen

Hi, i would like to know how to change sanitizing in wordpress. As default wordpress remove period (“.”) from post title when creating permalink so permalink for post with title “Hi.my.little.brother” becames “himylittlebrother”.
I need to have hyphens (“-“) instead of periods so title “Hi.my.little.brother” becames as permalink “hi-my-little-brother”.
Thank you.
