A wheel bearing is a thing that sits between a stationary part of a car (like an axle) and a rotating part of a car(like a wheel), allowing these to move easily WRT each other.
It CAN be dangerous when they go out, as that can cause the wheel to lock up, or even to come off.
Either of which are likely to end with the driver losing control of the vehicle.
Cost to repair depends. Some cars allow only the bearing to be replaced, which tend to be quite inexpensive. Others have the bearing as a permanent part of the hub, and then the whole hub has to be replaced, which costs more.
Eventually the beraring can seize and lock the wheel. Also driving it will cause more damage and cost more to repair

If you're planning to do it yourself, you MUST get accurate information (preferably from a service manual) on how to do it. Also, specialized equipment (pullers, presses, torque wrenches) may be required to remove and replace the bearings. If you don't do it right, the bearing is likely to fail quickly, which could be dangerous, expensive or both.

Not knowing how bad the bearing is, I can't say how long it will last before the wheel falls off. Drive to your local garage for repair and don't take the highway.
The wheel bearing can overheat and fall apart causing the wheel to come off of the vehicle. This can happen with little to no warning. Have this repaired it is very dangerous to operate a vehicle with a bad wheel bearing.The bearing will usually make noise first then proceed to a vibration. If left long enough the bearing will either sieze or break apart, with the wheel coming off (but that last is an extreme case).I the worst case the wheel can seize up. Go get it fixed as soon as you can, if it is making a lot of noise and you have had it for a while you might even want to have the car brought in on a flatbed truck to the repair shop
In my experience, any noise coming from the wheel bearings is an indicator of wear - and ultimately a repair job in my future. See "Related Questions" below for questions/procedures on Windstar front wheel bearing replacement.
