smooth a gear profile

Hi everybody,

I have a series of data forming a 2-d gear profile, however, the plot is too noisy and I need to smooth it and remove the irregular areas shown by black circles in the figure. Is there any way to accompolish that?

Here's the coordinates of the gear profile.

Best regards
