Tooth or Epstein pearls?

Jovana

FTM here, so my 4 month old developed these two white spots on the bottom left of his gums just the other day and I’m not sure whether he’s teething or perhaps these are Epstein pearls (but I undestood these only appear in newborn babies)

? Sorry I couldn’t get a better photo, he screams bloody murder whenever I touch his gums!
