hi are the front teeth pointy like shark teeth on the front chain rings if they are and not blunt then they are worn.
how old is the running gear because if its months then I would try just change the chain first and test ride it
if years and never been cleaned then I would do the chain and cassette its normally these two part that wear first
and like dicki said if you had pictures I might help more
