My 10 week old kitten has really bad fleas and I am concerned. He has been treated for fleas, but there seems to be a lot. What can I do to get rid of them fast and effectively?

You need to rid them from everywhere too. The yard, the house, the furniture,
I have used a lice comb and given them baths to try and get rid of them. '
The Advantage shots are the only thing that really seems to work especially when they are really bad.

Make sure you get rid of them even if it means taking them to the vet for the flea shots because I have had a few liters die from flea bites.

Wash everything that he has come in contact with(blankets, towels, clothes... ) and what can not be hand washed or washed in the washing machine I suggest to throw in the garbage. Its like that commercial 1 turns into 10 , 10 turns into 100 and they just keep multiplying, they aren't just on your cat but your furniture, your clothing, your floors...
