A chunk of tooth broke off of my tooth last night.  Why did that happen?

Usually it is because you are grinding your teeth in your sleep. Eventually it cracks your tooth and a piece may break off. You are pretty lucky if you are not in great pain, as the crack did not go though a nerve. No need to panic but it is probably a good idea to get to a dentist soon. He can fix the broken tooth, check for others that may soon crack or break and even get you a mouth gaurd to prevent it from happening again.

It certainly could mean a fracture which can be just as bad as a break. You didn't say how long ago this happened, but if you're feeling these symptoms a couple days after the incident you should see your Doctor about getting it X-rayed.

Yeah, ice is great for the swelling, but how about the trauma?  Any time a tooth is traumatized it is possible for the nerve of that tooth to become damaged.  This may lead to root canal therapy (RCT).  \n\nIt is important for you to make an appointment w/ your dentist.  An x-ray will be taken and your teeth will be evaluated.  Trust me....don't wait!  You should be able to be seen right away, b/c this is an emergency situation.  Your dentist should be aware of any situation going on in your mouth at all times.  These situations are recorded and can later on be used to evaluate a later condition or happening.\n\nThis is only a precautionary measure.  Yet, an important one.  It's always better to be safe than sorry!\n\nIf you don't take my advice, then watch out for discoloration of the traumatized teeth.  Now it is definitely time to make an appointment.  The teeth are necrotic (dead) and will need further treatment.

I know you don't want to hear this, but you must see a dentist.  You prob. have an abscess that needs attention. Putting off treatment by a dentist can put your health in danger, as well as your life.  Not getting help now will only make it worse.  I have once suffered a toothache from a hairline fracture in a wisdom tooth.  It was over the weekend and I thought I was going to go crazy from the pain.  No amount of Advil, oil of cloves, or any other remedy is going to help when it get's really bad.  I would never wish this kind of pain on anyone. There is nothing you can really do externally to help keep it at bay.  You need to have the infected tooth either extracted or opened up to let the infection drain out to relieve the pressure.  You also need an antibiotic to help get rid of the infection.  Don't wait, go as soon as possible.

please go to your dentist, he'll check on it without payment because it is his duty to do it. do not take a risk relying on others experience,it might came out for her but maybe not on you. you're right that there's a possibility to have an infection. it's your health! Be safe!

It's probably not a dry socket~ they usually hurt terribly!  As mentioned in other answers, it's likely a small piece of bone or tooth structure that broke off during the extraction.  These can act like a splinter in your finger that festers, then finally comes out and everything is better.  It could also be an abscess, which would need treatment ASAP.  You should call your dentist and schedule a quick "look-see" to be sure it's not an abscess.  In the meantime, rinse with warm salt water and it probably wouldn't hurt to message the area with a very CLEAN finger in case it's a retained piece of bone.  Sometimes it'll pop out with a bit of pressure.

It depends on the teeth around that one.  You may loose strength to nearby roots if you loose that tooth.  I am 30 and lost a back one on the bottom (and the dentist damaged the gum in that area).  Honestly only prob so far is every once in a while a sharp chip may get stuck back there, ouch.  Been out for like 6 years.

Was it a toy truck? how could that work out, exactly? If your tooth is a front tooth (Which I'm guessing it is) it isn't as strong as a molar. If it is a permanent tooth, you'd better hope it doesn't fall out. It probably won't though, unless its super wiggly.

Actually I don't really understand your question but im guessing you are talking about a fracture on your tooth. One of the way to test is to place a gauze on the tooth and bite on it. There will be pain when you release the gauze n not when you bite it. Once there's a fracture, it cannot heal by itself. It's the same like ur other body parts. You need to get it treated b4 it can heal. But if the fracture is only on the enamel, it's alright. You may want to visit a dental professional to find out how bad it is and whether something could be done. =)

Save the pieces. If the break was relatively clean, your dentist may be able to cement the tooth back together as a temporary measure. \nRinse your mouth well with warm water. If you were able to save the tooth fragment(s), rinse them under running water. \nIf an area is bleeding, apply a piece of gauze to the area for about 10 minutes or until the bleeding stops. \nApply a cold compress to the cheek or lips over the broken tooth. This will help reduce swelling and relieve pain. \nIf you can't get to your dentist right away, cover the broken surface of the tooth that is in your mouth with temporary dental cement, available in pharmacies. \nTake an over-the-counter pain reliever.

Please go to a dentist. There is nothing we can do for you. The dentist has to look at it. You may need it pulled or a crown.

First, you need to call your dentist.  Different things will be done depending on how bad it is damaged.  If you broke it off far enough then a root canal might be necessary.  If it is only chipped with little damage then the dentist might just repair it like it was a cavity by using the porcelain.

go to the dentist and have them take an ex-ray  i had problems with my teeth just as you i really didn't know what one was hurting so i had an ex-ray taken to find out.

see they don't lie to you that tooth needs to be pulled out:) Maybe it is psychological but I think it is mainly because your teeth are vulnerable or brittle. there are some enamel imperfections that enamel is very easly breakable... but how many times did it happened to you? 2? 3? it is not enough to make a connection.

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).

It occurs when the pulp (nerve) of a tooth is infected.  Yes it is dangerous if not treated because the infection can spread throughout the rest of your body.  More than likely, it'll just land you in the hospital.  Worst case scenerio... it could kill you.\n\nUmmm actually... to correct the person below me... it doesn't eat through your jaw, etc.  At the tip of each tooth is an apical foramen (an opening) where the nerves of the tooth flow out to the rest of the body.  If there is infection in the nerve of the tooth it can go out into the rest of the body through the apical foramen if it isn't treated.  And I would not compare it to cancer at all.

I had a similar problem before and it was an impacted wisdom tooth.   It happens when you don't have enough room in your mouth for the tooth to push through and it presses against your back teeth and puts pressure on your jaw.  It is very painful.  At the dentist they will have to take an xray to see if this is the case.  If you do have this going on they may have to cut them out, but don't worry they will give you a local anesthetic or maybe even sedate you completely before doing so.
