why does my tooth hurt and my face feels numb?

Depending on how old you are, it could be various things. I'm 18, and for me it's my wisdom teeth. Just about a week ago they started, and sometimes the pain is there, sometimes it isn't. It's a bitch, but go to the dentist, and chances are they'll tell you if it's a cavity, infection, or what. If you bite down and that eases the pain, your teeth are moving (wisdom teeth). If it hurts no matter what, and it's a sharp numbing pain, it's an infection or a cavity.

Your brain processes emotions, thoughts, impressions, physical sensations by releasing chemicals. Saying that depression is caused by a chemical imbalance is an oxymoron; your whole body relies on it’s own internal chemistry to regulate everything: we are chemical! When you are happy your brain releases endorphins, which is a chemical that makes you feel good. When you are depressed your brain sends signals to you in the form of chemicals to tell you, you are unhappy.\n\nLook at it this way. If your tooth aches because of a cavity and you take Advil or some other pain supressant, this chemical stops the signal of pain. But it won’t take care of the cavity. Keep taking pain killers everyday and you won’t feel a thing but that does not mean the cavity is going away.\n\nIf you are depressed that means you are not happy with something. By just taking medication you are stopping the signal, but you’re not taking care of the real cause.\n\nTaking the medication helps you stop feeling depressed, but if you don't examine your situation then you’re not really dealing with whatever is causing that depression.

It could be that you have a bit of gum recession in that area, or that the tooth was carved right down to the gums.  In both situations you will have sensitivity for for a few days to a few months.  Your dentist could also have possibly nicked your root a bit but I'm not sure; that's something another dentist will have to tell you.

Yes, allergy or diseases causing allergic-like symptoms (such as mast cell diseases) can cause the numbness. I have experienced this many times, sometimes in conjunction with headache, swollen eye, stuffy sinus, sore throat, ear pain, loss of hearing, and even swollen lip, all on one side of my face only. The weirdest is the half throat soreness, it feels like you can draw a line right down the middle and one side doesn't hurt at all while the other side is so painful it hurts to swallow. \n\nIt is extremely important, as others have suggested, to have this checked out, since some very serious conditions can cause this as well, including Bell's Palsy, stroke, transient ischemic attack, heart disease, and even migraine. If it allergy related, it could lead to anaphylactic shock, so be aware and don't shrug it off when it happens.

it doesnt matter whether its 3 teeth or 13 that are getting filled on the same day - your mouth will feel pretty much the same. The sensation will return a few hours later than usual because they will have to numb your entire mouth as opposed to just one side, etc. But other than that you will have to be careful for a few days to chew very selectively and slowly - because it will be harder to get used to the new levels of your teeth (fillings have sealants placed on top of them to make sure they stay in place longer and those sealants may feel really high to you for a day or two)

The size of the area of numbness depends on the path of the nerve that has to be numbed to work on that specific tooth.  Also, the nerves may lay in slightly different pathways in different individuals.  Sometimes (depending on tooth and nerve location), only a small area needs to be numbed.  Other times a larger area needs it.  Often, the dentist will give a numbing injection, wait a few minutes then tap the tooth and ask you if it is numb.  This is because he wants to be sure the right nerve "got" the medication.  It is annoying when a large area must be numbed, but sometimes this cannot be helped.  It is not a matter of "how much" of the med is given, it is what area and nerve it affects.  Talk to the dentist, I'm sure he can explain it better.   Hope all goes well for you today.  Oh, and the medication has only a temporary affect and does not damage the nerves.

I feel it like the whole DAY after I go to the dentist!  I hate when they floss for you and like dig way deep in your gums, that hurts so bad.  It's like "Thanks, I know how to floss."\n\nI wouldn't be worried.  If it lasts more than a day, call your dentist and tell them your concerns.

Root canal treatment is not painful if it's done under proper anesthetics.  But sometimes, if the tooth has been inflammated for a long time and even the bone around the tooth has started to decay due to the bacteria, the anesthetics might not work properly.  It's because of the acid environment the inflammation causes and the fact, that the solution of anesthetics can't dissolve in an acid environment, therefor can't give the proper level of numbness.  But it's only possible to feel something on the first visit, when they're taking out the nerve.  The following treatments (if further visits are needed) should be pain-free.  Also, there has been some research, that if You are very much afraid of the dentist, Your body produces more of the chemical, which might not let the anesthetics to work, so be as calm as possible and trust Your doctor. :)

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

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.

It is quite possible that the tooth has some kind of infection and it is affecting this gland.\nWhen a tooth or gland is infected or swollen it causes pain to radiate along the nerve that supplies that tooth or gland\nBefore you have a tooth removed,if it is infected you need a course of antibiotics or pulling an untreated tooth can spread infection to proportions that would amaze you.\nIf it is a swollen gland that is affecting the tooth,antibiotics will treat this as well.\nTry some warm salt water mouth rinses 3-4 times a day and try some hot packs on that side of your face. May not work but it certainly won't hurt.

My dentist uses a special CompuDent Wand that numbs the entire path of the needle and the tooth.  Sharp pain often occurs when a manual needle and its fluid compresses already sore tissue.  ComPudent is truly painless dentistry.  Even root canals are no sweat.  See the source (and insert your zip code to see if it is avaialable in your area).  Good luck.

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

if you originally had a toothache- a dry socket will hurt 10 times worse than the original toothach- if you didn't and you can feel your heart beating in the tooth and if you are- you know it! go straight to your dentist so he can apply a simple medication and fix you right up

hmm, it sounds like 3-4 hours, that would be when you might have eaten something?  What are you eating?  It could be something you are chewing or crunching that is irritating your TMJ.  The TMJ ones I get are similiar to migraines but not as bad and pain meds don't touch them.  \n\nFeel around the jaw and joint, do you feel any hard spots like spasmed muscles?  Anything hurt?  Do your temples hurt?  \n\nTry warm, moist heat on the temples and jaw area.  Also inside your mouth way back behind your upper molars or if you have wisdom teeth, there is a muscle that you can press on like a trigger point that helps.  I get alot of pain in my forehead too, another thing that helps is to rub something with menthol on the forehead and jaw area and right where the jaw line meets the ears, it helps relax the muscles and deaden pain.\n\nhope that helps.

Yes, any severe pain can cause you to feel nauseous. See your dentist ASAP to get the tooth sorted and hopefully that will make you feel better.
