how to remove dot in an url through htaccess

I'm getting 403 Access Forbidden error for certain urls. I found the root cause of the issue. wherever there is a dot(.) in an url, i'm getting the 403 forbidden.

There are thousands of urls have been indexed by google and hence i wanted to resolve via htaccess.

For e.g

I want to remove (dot) for the following url

FROM

http://www.example.com/zero/one/two/three/four/five/six./seven/eight.html

TO

http://www.example.com/zero/one/two/three/four/five/six/seven/eight.html
