6 Mo old w/double canines

So, my 6 month old cat/ Kitten has double canines. Both upper and lower. the hasn't lost the original set yet and his adult ones are growing in in front of the old ones. Here is a picture:


Is this something that will Solve itself or do they need to be taken out?

Usually it fixes itself, but sometimes the milk teeth need to be taken out.  I'd give it a week or so.
