Is it common for a tooth to be sensitive after a cavity has been filled in it??

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.

A cavity basically feels just like what it is--a sore, painful hole in your tooth.  If you have any doubts, go see a dentist--don't wait!  \nI doubt anyone here can tell you without examining your mouth first.  Is there a dentist in the house......?  I don't think so.

Chances are you will need a root canal due to the significant microleakage of the resin material.  DON'T TAKE THEM OUT!!!\n(Unless your restoration is failing!)  These restorations are extremely technique sensitive.  Over-drying the tooth before the resin is placed can also cause extreme sensitivity.

That sounds like a cavity.  They will numb your tooth and you will hear the drill and feel the pressure, but its not that bad (wink).  Some dentist will put you to sleep if you request it.

I do too. My dentist said it was from the fillings. Have it checked out very soon to be sure.

It's normal to feel pain after a temorary filling has been placed. The gum and nerves are still healing from drilling and all the work done to have that filling placed. You're just experiencing a temporary sensitivity to hot, cold, even in some cases...if you go outside and breath in through your mouth, air can irritate it also. If the pain persists, suggest to your dentist that he should place a transparent cap on the tooth instead of a temp filling.

sensodyne tooth paste, or other such products, work by blocking the tubulents in the dentin. Tubulents are tiny little holes in the dentin of your teeth, that lead to the pulp chamber. These holes are natural, but when they are exposed, the will make your teeth feel sensitve. Therefore, by using sesodyne, you can block these holes, and prevent the sensitivity, but often times, when you stop using the toothpaste, the holes will be exposed again, and the sensitivity will return. In this case, I would advise you to see your dentist and explain your concerns. There are several options, depending on your condition, that he/she will be able to offer as a more permanent solution.\n\nI hope this helps,\n\nCraig

give it a little more time and if it doesn't get better, go back to your dentist again since you may need your bite adjusted again, or the filling just wasn't enough and you may need a root canal. There's various reasons your tooth could still hurt, but it shouldn't hurt for no more than a couple of months at most. If it does, the dentist needs to do more work on it.

I've had 4 done in the past and I need a whole lot more done soon. Two of my cavities were quite big, and it was a bit uncomfortable getting them filled, but the other two were small and I didn't feel a thing, so don't worry about it. Even if your cavity is deep and close to the nerve, it's not excruciatingly painful, it's just a bit uncomfortable. As far as how long it takes, again it depends whether it's a small filling or a larger one that has to go on two or more surfaces of the tooth. It shouldn't take more than about 20 miutes or so I wouldn't have thought. Good luck!

Cavity. That's the word no one wants to hear at the dentist's office. A cavity (say: kah-vuh-tee) develops when a tooth decays (say: dih-kaze), or breaks down. A cavity is a hole that can grow bigger and deeper over time. Cavities are also called dental caries (say: kar-eez), and if you have a cavity, it's important to get it repaired.\n\nBut why would your tooth develop a hole? Blame plaque. That's a sticky, slimy substance made up mostly of the germs that cause tooth decay. The bacteria in your mouth make acids so when plaque clings to your teeth, the acids can eat away at the outermost layer of the tooth, called the enamel (say: ih-nah-mul). \n\nIf you don't go to the dentist, the acids can continue to make their way through the enamel, and the inside parts of your tooth can begin to decay. If you've ever had a toothache or heard an adult complain about one, it may have been because there was a cavity that reached all the way inside a tooth, where the nerve endings are. Ouch!\n\nYour dentist will carefully examine your teeth and may take X-rays. If your dentist discovers a cavity, he or she can repair it for you by first removing the rotted part of your tooth with a special drill. The dentist then fills the hole in your tooth with a special material. It's called a filling. \n\nDoes it hurt? Sometimes it does, but your dentist can give you an anesthestic. That's a kind of medicine that will numb the area around the problem tooth while you're getting your new filling.

I hope not! I've noticed I've been doing it since my mid-twenties, but I was able to "deal" with the dull pain. In the past six months, though, a filling came out of one of my molars and then a molar on the other side actually cracked! My dentist repaired both, but said it was due to my grinding, as were the cavities developing from all the wear and tear on my teeth enamel. So next month I'm getting fitted for a mouthguard to wear when I sleep.

I can't tell you that, but if you go to the dentist they can. If you can handle a little pinch, than you can handle getting a cavity filled. The shot of novacain is fairly painful, but not extreme. Then let it work it's magic, and tell them if you can feel them drilling. It's really not that bad at all. I'm ashamed to say I have had four cavities filled!

No, it's not normal!  Go back to your dentist and get x-rayed.  If he again says it's nothing, go to your doctor.  Something is clearly wrong that is causing the area to be inflamed (the swelling).

I'm a dental hygienist.  It depends on how big the "chunks" are that your losing and whether or not its tooth or an old filling.  If its tooth then you probably have a lot of decay and it would be best to get it checked out before the decay gets too deep and you need a root canal and a crown.  If the decay is small, you might only have to get a filling.  Only the dentist will be able to determine that.  But I wouldn't wait for it to get worse.

White patches are not signs of cavities. Usually it will be a darker colour. No, cavities do not spread from tooth to tooth. Brush your teeth at least twice a day, and floss

Well, first of all if your dentist said it was normal, it probably is. However, whenever I get anything done to my teeth that requires anesthesia, my mouth swells up at the site of the injection. I found out that it was a minor allergic reaction to the novocaine. This allergy is extremely common and will clear up in a few days. However, if after about two weeks the swelling doesn't go down, as much as you probably don't want to, you need to go back to the dentist, because there might be a real problem. In the mean time, take your dentist's advice and take some ibuprofen to reduce the swelling. Good luck!

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!
