What is the purpose of getting your wisdom teeth taken out?

Basically, most people's jaws are too small for them to come in and function properly as teeth. Sometimes it's too small for them to even develop properly, and often they'll wind up growing into awkward positions and/or ramming into your molars, causing extreme pain. A few people do have the space for them, but most people don't, so they have to come out. As for how to know if you need 'em out, when you get to be around 18 and you go for a checkup, the dentist might offer to take an x-ray to see where they're at. Or, in other cases, they'll start coming in and you'll know yourself from the resulting pain.

Sometimes they don't show up til the mid twenties, and yes - they are a problem for some, while no problem at all for others. The way they are a problem is if they grow in weird, or the most common, you don't have room for them. If you let it go too long like I did, it will push some of your teeth together and make them uneven.

Wisdom teeth can be impacted and get infected. They also can crowd your mouth and push your other teeth forward, sometimes they can cause your other teeth to crack. When you feel your teeth move or seem to have alot of soreness in the back of your mouth. Wisdom start popping thru in late teens, and it can hurt alot for some people. If you get alot of gum/throat infections or pain you will know. Your dentist will also notice if you do.

Not everyone needs their wisdom teeth pulled out. A lot of times they will need to be taken out if they are growing sideways or to where they will cause discomfort and never fully erupt. Sometimes if they are growing the wrong way they can be pushing your other teeth and cause them to shift, or cause crowding. If you have your wisdom teeth and they are grown in like your other molars sometimes having them back there makes your molars more prone to decay. Most of the time doctors will tell you that you need them out, other than that it all depends on the person :)

We only have enough space for 28 teeth, and the wisdom teeth make 32. It knocks out the alignment on some...not all, if you have the space for them

Our family dentist stated that wisdom teeth were no use an they were to far back to chew on

I went through oral surgery to remove my wisdom teeth at about 21. It is pretty important if you want to keep your teeth straight. As mentioned before, there is usually not enough room in the mouth cavity for the extra wisdom teeth, they are a leftover from a time when the human face was more elongated. Besides screwing up the alignment of you teeth, wisdom teeth coming in crooked can cause headaches and lethargy because your body may treat the extra teeth as a foreign body and attack them or infection of the wisdom teeth can cause toxic shock syndrome and blood poisoning.

well, are crowding your molars they could actually make your other teeth crooked. also if 1 or all of them start to hurt. if they already came in and there strait that's rare but then theres no problems. generally there natures bad joke .

well, i think the main reason is because they are so far back and hard to keep cleaner than the other teeth, plus you really don't need them much for chewing. Sometimes they push your other teeth ahead or cause pain. One of mine was SO rotten (and all my other teeth were great), that it caused pain. I had conscious sedation (I was pretty much asleep when I had mine done). It's up to the individual, I know some who still have theirs and have no issues.
