Why do fillings hurt when they get cold?
459643
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.

This may sound goofy, but you may want to rule out a dental infection/problem.  They can often cause body aches, lethargy, etc.  Be sure to see your dentist.

If it hurt a lot and then suddenly stopped hurting, it suggests that the tooth died. That means it was really badly decayed underneath the filling and the decay reached the nerve and then killed it. Even though the tooth stopped hurting because the nerve was dead, the decay was still there and it must have been really severe and the dentist decided the tooth couldn't be saved with a filling or a root canal.

It could be an ear infection or a toothache.  I know it sounds odd, but I had similar pain and it was because I needed a filling!

Finding some bits of metal after a filling is normal.  Don't panic.  If it keeps it up after you've brushed tonight and tomorrow morning, then I would call my dentist.\n\nYou should be able to brush and eat on that side as soon as it feels okay.  There aren't restrictions with that type of thing as far as I know.  I always did afterward though you might want to wait a day to be sure..  You might have some sensitivity to cold for a bit afterward, so be careful of that.

Yes, unfortunately you can have a cavity in a tooth even if it looks fine to you. You can get cavities that form in between your teeth (especially if you don't floss enough) and you wouldn't be able to see that looking in a mirror because you're looking at the top of your tooth. Unfortunately, a tiny cavity on the surface of a tooth can make a big cavity inside the tooth and you don't know anything about it until it starts to hurt.\n\nIf you have a toothache, you must go to your dentist - it won't just go away, it will get worse if you don't get it fixed. Yes, you'll most likely need a filling if you hae a cavity, but don't worry, it doesn't hurt because they make you numb first.

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.

if it hurts really bad you could have dry socket. it happens when you smoke or drink from a straw or basically suck anything too hard. you need to go back to your dentist, because it won;t just go away.

ROUGHLY speaking, cavity pain progresses as follows:\n1. Cold sensitivity - small to medium hole. Probably able to be repaired with a filling.\n2. Hot sensitivity - medium to large hole. May be very close to the nerve and require a Root Canal Therapy or extraction.\n3. Hot sensitivity with throbbing - RCT or extraction.\n4. Dull ache - tooth nerve (pulp) may be dead and infected, and you are feeling the development of an abscess. RCT or extraction.\nThe longer you have had the pain, or the more intense it is, or the longer it lasts each time it affects you, then the more likely an RCT or extraction.\nPlease only take this as a rough guide, and seek dental treatment ASAP. The ssoner you seek help, the better your prognosis.

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.

from my experience of visits to my dentist, the tickly sensation you talk of, arises from an injection which kind of disables all the nerves (pain receptive nerves to be precise) , in your gums area so that you feel less pain while he is working on your teeth.

First let me say I'm sorry you are in pain. Why does it hurt? you could have a cracked tooth, so when something very cold or hot gets in there it lets you know it. Sometimes people have gum problems that cause their teeth to ache. Try flossing around the area you might have some food lodged in there. Rinse your mouth often with one of those good mouth washes that is antiseptic. Always have good dental hygiene it will pay off in later years.

Signs that you grind your teeth:  teeth are sensitive to cold, they are tender when you wake up in the morning, jaw is sore, either your canines or your molars appear to be getting flat.  Have your dentist look at your teeth & check for these signs. They can make you a night guard to wear so that you are grinding on the acrylic rather than your tooth structure.  Good luck

The first stick of the novacaine hurts, but after that, the most uncomfortable thing is when they have you bite down on the flouride trays and they dig into your gums.  The drilling and filling does not hurt because they numb you.

When your body feels really cold stuff at the roof of your mouth, your pheno-palantine ganglion send off signals to your brain which cause vessels to swell. Thats what hurts, so if you do get a brain freeze, the fastest was to rid yourself of it is to stick your tongue to the roof of your mouth to warm up the pheno-palantine ganglion so they send out good sgnals and tell your brain to stop swelling.

If its an upper tooth,its most likely your maxillary sinus since the roots of our upper teeth often sit right at the maxillary sinus.Even allergies can make your teeth hurt because allergies can cause sinusitis and fluid levels in your sinuses
