LO covering their ears - teething?

A • Mama🌈🎀💙

My 21 month old has been covering her ears (earmuff style) on and off for a couple of weeks now. I thought it was an ear infection at first but she doesn’t have one. Is this a sign of teething? This started when she was getting her “canine” teeth in. One is now fully through and the other is just a tiny slither. I can see one 2 year old molar under the gum line. Wondering if anyone else’s child does this? Thanks for any advice.
