probably fake tooth- any idea of species?

hello!! hoping this is the right subreddit? this showed up on my craft desk in the garage about a month ago and i assumed it was a random find my dad had gifted to me,, i finally got around to asking him and hes never seen it before. i'd love to know what animal its from or is trying to replicate . im 99% sure its plastic but not 100%. the brown marks do seem very realistic and the lower part seems quite real, but the top (root?) part is very plastic-like. its about 4cm long (nail polish for scale in last photo)

thankyou !
