There is nothing more annoying to a guest (whether they say so or not) than having your dog bite their hands, arms, clothing, etc. - whether they are hurting/harming or not. It is not socially accptable, and the puppy needs to learn this.
Since you say you didn't know how to teach the pup not to mouth you, you might have your work cut out for you. But the alternative is going to be either, a) a worstening condition where the pup's behavior gets more and more aggressive or annoyingly playful; b) people no longer wanting to visit you; c) someone getting annoyed and smacking your pup.
At 8 months, you should have some basic obedience down, so you need to teach the pup that this is not acceptable. Ask the victims of the behavior to assist by staying calm and not acting like it is cute, etc. A firm "No!" might be enough, or you might have to pinch the upper lip into the teeth to release (along with the "no"), etc. Learn what works best for your dog.
Actually, the best thing to do is put the dog into a sit/stay or down/stay when guests are present until he calms down. Let him learn that petting and affection is initiated by the humans - not by him.
Best of luck! Post your progress....
