yeah, you're going to need to replace it because when your bristles get worn out, they're not gonna clean your teeth as effectively.. you'll usually notice that your teeth don't feel as clean as they used to. it's the same as replacing a manual toothbrush when it gets worn out. if you think it's too expensive, you can wait a little to replace your brush head.. but you're gonna end up needing to change it eventually.

You should the change the head on an electric toothbrush as often as you would get a new manual toothbrush. The American Dental Association recommends changing toothbrushes every 3-4 months, but I just do it twice a year.

Just like any other toothbrush, it's important to change the head of your electric toothbrush to avoid bacteria build-up. Even though they are expensive, a good rule of thumb is to toss it out after each time you get sick.
If you get sick often, try to use a manual toothbrush each time you get sick. You'll be able to save the expensive toothbrush head for a little while.
Try to change them out every 3-4 months anyway.
Electric toothbrushes are great, but they shouldn't be excluded from the general rules associated with toothbrushes.

I would guess that you should change the head on an electric toothbrush just as often as you would replace an ordinary toothbrush, if not more often. I'm sure that the more intense beating the bristles on electric toothbrushes get would cause them to wear faster.

Every 6 months or after you get sick...powered toothbrushes may not show signs of wear on the bristles, but after about 6 months they are not as effective at removing the plaque.

Yes, very much so! First of all, the head gets a lot of bacteria on it from brushing. This bacteria could cause problems such as gingivitis or pariah. Second, bristles begin to fray and can rub the gums the wrong way. This constant rubbing can cause we gums to recess. You just want to buy disposable brushes if you find head replacements too expensive.

The bristles with thin out over time and not work as efficiently. The toothbrush companies say you should change them every three months. I change mine every 3-5.
You cant just never change it though. Its also just not very hygenic.

Of course. It's not good to use the same bristles for a prolonged period of time. It stops working as well over time. It's good to buy a new one every 6 weeks or so. Some will show wear & tear letting you know it's time to buy a new one.

It's just like getting a new toothbrush. They do get yucky.
You could probably extend their life by soaking them in mouth wash when not in use.
