Just because you brush your teeth doesn't make you immune from cavities.\n\nSudden sensitivity to cold is a sign of a cavity.  Suck it up and go to the dentist, or you'll have more than just an occasional pain.

It could be a condition known as Angular Stomatitis, sometimes it is a sign of anaemia. You should talk to your doctor and he will tell u.\nGood luck!

Hey I feel your pain! Had mine removed last fall.  For the first few days I just ate food I didn't have to chew so I didn't get food stuck in the wounds - yogurt, etc.  Also, and this is important!--  Ask your dentist's office for a special thing that looks like a clear plastic little syringe - you fill it with water and spray into your wounds to clean them.  That helped me a lot!feel better soon, good luck! :)

Yes, it is normal to experience some sensitivity after this has been done! If the sensitivity persists, tell your dentist!

hey sounds like tmj and you need to see a dentist or an oral surgeon.  I know.  Have been there.  Nope it is expensive but worth it.  You will prob have to get an appliance to stop the clenching at night.  Better an appliance than drugs to drug you.  hope this helps  J

No it should not.  Your filling must be very deep in your tooth near the pulp or nerve of your tooth.  If your sensitivity to cold lingers for more than a few seconds (which can be normal) or if you are sensitive to hot things you should see your dentist, or an endodontist.  You may need a root canal.  And root canals are not as bad as people say they are.

Tooth  movement can definitely occur as you get older and you loose the tone in your lips 60s and beyond.  The tongue can push it out.  If you are younger, 40ish, I would really suspect eriodontal disease, when you loose enough bone its like a deck of cards collapse begins to occur rapidly.

Ok, Sherm has a very good answer, but to put it in more simple terms. You will need to give it some time to heal. If you have hot or cold sensitivity, there could be nerve involement, meaning that you may need a root canal. In the event of a root canal on a molar you will need to also  have a crown placed on that tooth to preseve it. After having the nerve removed that tooth no longer has a blood supply and will become brittle and break off. A crown will protect you investment. At the very least you'll need to have your bite checked and possibly adjusted. With this, it still may take a few days to get better, it's kind of like a bruise. Take care of that A.S.A.P. Good luck!

I'm a dentist.\n\nAssuming that the tooth hasn't moved, your bite hasn't shifted causing the filling to be hit harder, or the filling isn't high, it could be that you cracked the tooth.  Does it hurt when you bite?  And if it does, does it hurt when you bite down, when you release the bite, or both?  Any hot/cold sensitivity?\n\nSee your dentist.

It might just be a canker sore. If you aren't in pain I wouldn't really worry about it, but if you are really concerned, then see your doctor.

Until it doesn't hurt to chew anymore. I got some molars taken out before I got braces when I was little, and I was on an all-liquid diet for just a few days. Keep ice cream around too- milkshakes are easy to swallow and the cold will numb you a little bit.\n\nGood luck! :)

probably because the gum tissue on that specific area has receded (reduced its height), exposing the cervical portion of the tooth, that contains millions of microtubules that directly connect to the pulp tissue(nerve )of the tooth, thus causing an instant response to the cold stimulus.

Happened to a friend. Your teeth develop hairine cracks running vertically. As you continue to chew ice the cracks expand exposing nerves and causing pain. In time you will need                  crowns. It takes several years for that though.

fillings are either made of metal or plastic.  both materials flex with a change in temperature.  when you drink extremely cold or hot beverages, the temperature change is communicated to the nerve of the tooth since the filling is in such close proximity to the blood and nerve supply of the tooth.  if the filling is really deep, such sensitivity is to be expected until the tooth heals.  sometimes, the tooth is unable to heal itself and the nerve tissue becomes infected necessitating a root canal procedure.  \nbottom line:  sensitivity is normal with extreme temperatures as long as the pain goes away immediately after the cold/hot stimulus is removed.  if the pain lingers for 30 seconds or more after the stimulus is gone, the tooth may be unhealthy.

Its probably a canker sore.  You pretty much just have to wait those things out.  Keep acidic foods away from it in the meantime.  I get one everytime I go to the dentist and the last time it took a week for it to go away.

First of all, have your teeth cleaned by a dental hygienest. Your general dentist should have several on staff. She and the doctor will examine you after your cleaning and determine how many cavities you have. They will also need to take x-rays to see inbetween the teeth that are too close together. A new/small cavity generally doesn't hurt. Once a cavity become sensitive to sweets and/or hot/cold, it may be time for a root canal. If it still isn't treated, the only option is usually extraction.

i am not a dentist, but i have extremely sensitive teeth.\nwhen i use any toothpaste that isn't made for sensitive teeth, the sensitivity gets worse.\ni use crest sensitivity.\ni use very little ice in my drinks and never drink anything that is really hot. i tend to stick with cool, warm, or room temp drinks. same with foods.\nasprin or ibuprophen sometimes helps with the pain.\ni even brush my teeth in slightly warm water.\nmy dentist told me that the cause of my sensitivity is two-fold:\n1. use of mentadent toothpaste stripped the enamel off my teeth\n2. i brush too hard\n\nfrankly, i have just gotten used to the pain.\n\ni really hope you get your question answered in the way you need!! tooth pain is one of the worst! good luck
