Yay, I'm not the only one!!!  Have you noticed that happens less in the Winter?  It's mostly allergy related, my dentist said I have an extra bone in the roof of my mouth that is common, and that, with the addition of allergies, even if you don't think you have them, the "skin" there strethches, gets tiny little tears and then itches when it's healing...a fast solution is to lightly brush the roof of your mouth so that you don't ake any more tears, rinse with Listerine, and then rinse or drink sips of ice water.  If all else, fails, and if yours seems worse at night like mine, take a Benadryl allergy---awesome stuff and gets rid of it completely!!  this only happens to me maybe once a week during the spring.summer and maybe once a month in the winter

Ultimately by not taking proper care of your teeth.  Also, I cannot express enough the need to floss every day!  I have seen people that brush their teeth reguarly and have had very few if any cavities and yet they develop periodontal disease and lose their teeth because they didn't floss.  So make sure to brush 2-3 times a day, floss at least once a day and see your dentist every 6 months for a cleaning and exam.

I'm a dentist.\n\nAttrition, my good friend.  Attrition.\n\nAs we age, our teeth tend to wear a little, but just a little.  Not enough to significantly alter the shape of any tooth.\n\nDid you know that the only time that our upper teeth and lower teeth should come into contact with each other is when we swallow?  Other than that, they should never touch.  Not when chewing your food.  Not when talking.  And certainly not at rest.  This is a fact.  The key words here, however, are "should never".  Unfortunately for most people, they touch much more frequently.\n\nWhat really changes the shape of our teeth is wear against the opposing teeth.  Many people grind their teeth or have some sort of habits that involve touching teeth together.\n\nAdditionally, dental work (with the exception of metallic materials) wears away the opposing teeth more quickly.  Porcelain crowns are notorious for causing excessive wear on teeth opposing them, as porcelain is much more abrasive than enamel.\n\nCanine teeth, both upper and lower (but especially the upper) serve an extremely important job in the mouth, and it is why any good dentist would make every last effort to save a canine tooth rather than extract it.  To explain this, I have to give you a little info about our masticatory system.  We have various muscles that close our jaws: masseter, temporalis, and medial pterygoids, all of which are controlled by the mandibular branch of the trigeminal nerve (Cranial nerve 5).  This nerve originates in our brainstem, if memory serves.\n\nTeeth do not sit directly in bone.  They are suspended by the periodontal ligament (PDL for short), which has many nerves in it, some of which are pressure sensors that tell your brain how much pressure is being applied to the teeth.  That's how you know to chew hard on beef jerky and softly on ice cream.  When your molars' PDLs pressure receptors are stimulated, your brain knows that it is ok to provide full biting force with your muscles of mastication.  After all, they are thicker, more robust teeth that can withstand those forces.\n\nIn contrast, your front teeth (canines included) are less robust and are not suited to withstanding heavy biting forces.  As a result, when the PDLs of your front teeth are stimulated, feedback is sent to the brain causing your muscles to reduce their force.\n\nWhen your jaw is in its "neutral" position (for lack of a better word that the lay person can understand), your molars will occlude with each other, but your anterior teeth won't (i.e. the shouldn't, unless you have some abnormality).  Your teeth are safe this way.  Move your jaw side to side or even forward a little, and what happens?  Your canines start to hit eachother, and through feedback from the canines' PDLs your brain knows to relax the muscles.  It is a protective mechanism for both your teeth and your jaws that prevents you from biting hard with your jaw in a position that can cause damage to the teeth or TMJ.  This is known as "canine guidance".\n\nIndividuals who, for one reason or another, move their lower jaws more than usual are rubbing their canines more, hence the attrition.\n\nThis is about as simple as I can make the explanation.  I hope it helps.  I'll bet you never knew there was so much to the profession of dentistry!

Because there is absence of any (coloring) pigment present in teeth. That's why they are always white. Geography doesnt much manipulate the biological composition of humans.\n\nThe color of calcium is also white, which is the prime substance present in the teeth.

You are good!!! Thats exactly what you are experiencing. When the cold air touches your tooth you feel pain. That is the stimuli from exposed dentin. Usually the first sign people feel when they know they have a cavity. Get to your general dentist! Good Luck

HONEY I AM 25 AND STILL NO TEETH IN SIGHT. WE ALL WORK AT OUR OWN PACE ... DONT RUSH IT. SOME PEOPLE DONT EVEN GET THEM OR NOTICE WHEN THEY DO IT DEPENDS ON IF YOUR MOUTH HAS ENOUGH ROOM TO COME IN.

Itching is low grade pain. Sometimes a change of temperature balances the nerve endings just enough to change the natural signal for awhile.

Well, three quesses.\n According to your hypothesis we rub in dirt and bacteria, so maybe nature is doing this on purpose to make us get bateria on us to build up our immune systems. \n Or maybe there are chemicals or enzymes in things that bite us or touch our skin (like being allergic to metal) that cause the itch. \n But I think the most popular answer to this queston would have something to do with the fact that during a months time your skin is completeky recycled meaning, the layer that was on the very bottom at the begining of that month is now the top layer of skin. You itch because dead skin is needing to be scracted off.

when a bug bites you it injects a bit of its saliva and sometimes poison into your skin which causes itchyness so when you scratch any itch it feels better but try not to, it will keep the wound from healing because itching also means its healing and if you keep any wound open it is vulnerable to bacterias and infection.

look at this ewbsite, they explain how each constituent works, improving blood supply may be the reason but there is no scientific data suggestiong itching from improved blood supply to the skin, if itching persists or worsens, see a doctor, good luck

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.

It could be that the temporary crown is a little high and may need to be adjusted... get back in to see your dentist.  You shouldn't be experiencing any sensitivity to cold, etc if you have had a root canal... sensitivity is normal for a tooth that has not had a root canal, but not normal for a tooth that has.

Get some ambesol. When I got my wisdom teeth it itched instead of hurting, and that's what I used. Apply it with a cotton swab so that your entire mouth doesn't become numb.

hmm...that's weird. that only happens to me if I eat food that is too hot before it cools down some. but, sometimes the insides of my gums get a slimy coating, and I discovered that was from using a toothpaste that was too strong. I use crest multi care cool mint and the problem has gone away. maybe you should try to use a sensative toothpaste or google your symptoms

Nah but your teeth feel weird at first.  It takes some getting used to the smoothness of teeth

Because their teeth and gums are extremely sensitive and in many cases they use dentures.
