Are Epstein Pearls sharp and wide? Or is it a tooth?

My 6 month old son has had a tooth it looks like coming in for two weeks now but I read about Epstein pearls and now I’m not so sure! I’m a ftm. I’m just wondering cause it’s like long in his gum line and it’s on the side and it’s extremely sharp. It feels like a tooth trying to break through.
