Why do we grow wisdom teeth?

To give 0ral Surgeons their mansions and expensive cars!!!\n\nI guess it's the same question as why do people have an appendix?\n\nSome people's wisdom teeth grow down properly and so they can use them like normal teeth. The proplem with most people is that their mouths are too small to fit the teeth so they grow at funny angles.

Getting your wisdom teeth taken out will be easy!  You won't even be there very long.  Just take it easy for a few days after.

Wisdom teeth are third molars that usually appear between the ages of 18 and 20 (although they may appear when older, younger, or may not appear at all). They are called "wisdom teeth" because they appear so late—much later than the other teeth, at an age where people are supposedly wiser than as a child, when the other teeth erupt. Often they need to be removed when they impact against other teeth—colloquially known as "coming in sideways."\n\nWisdom teeth are sometimes described as an example of a "vestigial" trait. Some argue that recent changes to softer diets which cause less wear on the teeth may be causing the third molars to be less useful, and, in fact, problematic in many humans. Alternately, it is possible that wisdom teeth were useful when it was common for humans to lose several teeth to decay by the age when they appear.\n\nAlthough most people have four wisdom teeth, it is possible to have more or fewer. Absence of one or more wisdom teeth is an example of hypodontia. Any extra teeth are referred to as Supernumerary teeth. [1] [2]

safety in numbers, being omnivorous we need several types of teeth for different foods. Also like sharks, we are apt to lose teeth, unfortunately unlike shark we cant grow them back. so separate teeth  mean that each one has a potential for not falling out

Probably.  The case must be approved by Invisalign before they even make it.  If you have wisdom teeth that caused your problem in the first place, why try to fix the problem without addressing the cause.  They probably would not even make the case.

Not all cavities grow! By drilling into a small cavity you will have to make it larger and therefore create a bigger filling, so tiny cavities are left to see if the grow. The best way to stop it happening is to limit your sugar intake. Sugar rots teeth and the teeth take 3 hours to repair themselves after a sugar attack, so in short limit the amount of sugar to a minimum of 4 hour intervals. This includes tea & coffee (if you have sugar), all drinks except milk and water and most foods i'm afraid. At meals you can have as much sugar as you want, sweets, fruit, fruit juice etc as you meal will contain sugar. As I am a dental nurse, this is the advice we provide to our patients and have really noticed the difference in the patients that follow the advice. And the most important time to brush your teeth is before bed with an electric toothbrush.\nHope this helps

I'm a dentist.\n\nWisdom teeth do not cause crowding.  That is a common misconception.\n\nThey can, however, push against your second molars and cause resorption of the roots.\n\nThere are many reasons for which wisdom teeth are removed.  If your dentist recommended it, the you should have it done.  Certainly, if your dentist referred you to an oral surgeon you should go for the evaluation.

I have seen wisdom teeth erupt as early as age 14 althout it's usually around the age of 18 when they begin to erupt.  As a general rule, if they have not erupted by the time you are 24, then they are not going to.  See a dentist so a panoramic xray can be taken to determine if you even have 3rd molars and if they will erupt fully.

Human teeth don't grow back. As most mammals, we are diphyodont, that is, we have 2 generations of teeth (milk teeth, and definitive teeth). We change our incisors, canines and premolars once during childhood, and our molars (which have no replacement) grow later and slower (some people never get their 3rd molar). \nSo if you lose your milk teeth, you get a second set; but if you lose your definitive teeth, it means dentures.\n\nOther vertebrates are polyphyodont (or oligophyodont), that is, they have multiple generations of teeth and constantly replace them.

My wisdom teeth did not completely come in until I was in my 20s.  They took forever to fully grow in.  I did not have to get them removed.  But because they are so far back in my mouth, it is a challenge to brush them properly.  Four years ago I got a cavity on the surface of one facing the back of my mouth.  The dentist could not reach it to fill it (partly below the gum line) so he pulled the tooth.  It was in the top of my mouth, he only used Novocaine.  The noise of the extraction was horrible (crunching) but the pain was minimal.  The upper molars only have one central root. The bottom molars have four roots on each corner.  Most complications arise from not completely getting all of the roots out, dry bone (when there is not flesh over the extraction site), and infection.  Also some people have bone in the way of the extraction or it is damaging nearby teeth.  After my extraction, my dentist used a laser to cauterize the wound and kill the bacteria.  I went home that day with Tylenol and was a little sore for a couple of days, but it was not that bad.

WISDOM TEETH: IS IT WISE TO REMOVE THEM?\n\nCommon misunderstandings surround their name origin, removal reasons and pain sources\n\nWisdom teeth, also known as third molars, are the last teeth to grow in the back of\nthe mouth. Common misunderstandings surround their name origin, removal reasons and\npain sources, according to the Academy of General Dentistry, an organization of\ngeneral dentists dedicated to continuing education. \n\n"The name 'wisdom teeth' is age related - third molars don't erupt until teenage\nyears and beyond, when people theoretically are more wise to the world," says Trey\nPetty, DDS, FAGD, spokesperson for the Academy of General Dentistry.\n\nCommon reasons for wisdom teeth removal include impaction, pain and crowding of the\nother teeth, which are typical tooth growth characteristics.\n\n"If wisdom teeth are not visible, they are impacted or unable to erupt due to space\nand size limitations," says Dr. Petty. "Impacted teeth don't have enough room to grow,\nand will lay beneath the gums, which may or may not be a problem." \n\nPain and tooth crowding are also top wisdom teeth problems. "Adults have forgotten\nwhat normal pain from a growing tooth feels like," says Dr. Petty. Complications also\ncan arise when wisdom teeth partially erupt. The broken gum acts as a breeding ground\nfor bacteria and germs. \n\n"When wisdom teeth partially erupt, food gets caught in the gums and may cause an\ninfection, swelling, growth of a tumor or cyst and pain," says Dr. Petty. "If this\nhappens, consult a dentist before problems worsen and affect overall oral health."\n\n"If wisdom teeth have erupted, the key to preserving them is maintaining good oral\nhealth by brushing twice a day and going to see a dentist twice a year," says\nDr. Petty.

Usually, wisdom teeth are erupted in the late teens/early twenties. If yours have not erupted, but you're feeling discomfort, go to your dentist. The only way you're going to know what is happening is by having an xray. You could have impacted molars, cysts... a whole range of things. Only your dentist can tell you this. However, not all people have all of their wisdom teeth (I have none... they are congenitally missing). So... again, only a dentist will be able to tell you how many wisdom teeth you have, if they are going to grow in and if there are any problems. Request a panoramic xray.

Because they never stop growing them. Their survival has evolved to depend upon their teeth, so their supply of teeth never ends. They have row after row of teeth, which keep growing back as they are lost. If you lost teeth like a shark did (because yours don't grow back), you'd have dentures by the age of 22.\n\nGood Luck!

most often the oral surgeon that removes the wisdom teeth put you under general anesthesia.\nYou don't feel anything.\nWhen you wake up later you will feel some discomfort, but the oral surgeon will give you pain pills and an anti-biotic for the infection...impacted or erupted wisdom teeth or bony impacted teeth have to be cut out and need stitches\nThe top ones are a piece of cake, but the bottom ones stay sore longer, or on me they did..

If your wisdom teeth are unable to fully erupt, then yes, it is best to have them removed.  If they are partially impacted then food and bacteria will eventually caused them to become infected causing pain because you are not able to clean them properly.  Even if they are fully impacted, it is still best to have them removed because they are pushing your against your other teeth which will cause problems later down the road for those other teeth.
