Canine tooth ID

[Lizz6]

Hello,

Yesterday I came across this tooth on a beach local to me in south west Scotland. I first thought seal but have discovered it’s too large and can’t think what else is in the waters around Scotland that could fit a canine tooth so large. Any help is appreciated.

Looks like a horse incisor, to me.

Sorry to say, but I believe you are looking at it upside down, I agree with Fossildude on this one.
