why there is blood in teeth?

I'm not really sure what you're asking.  But, there is in fact blood in everyone's teeth.  You shouldn't be able to see the blood from the outside of the tooth in a healthy tooth.  Every tooth has a pulp chamber (the root canal) filled with blood and nerves.  The teeth need nutrients and hydration just like every other part of your body.  \n\nIf you see blood when you are brushing your teeth, then you have gingivitis.  Bleeding gums are not healthy.  Brushing twice daily and flossing once a day will treat the gingivitis.  Also rinsing ONCE a day with Listerine or Crest Pro-Health Rinse can treat gingivitis.  Do not rinse with Listerine three times a though as suggested above.  Listerine contains alcohol which can really dry your mouth out if used too often.  If you can't stand the burn of Listerine try Crest Pro-Health rinse.  It does not contain alcohol, and works as well as Listerine.

You might have a bad tooth and not know it. See a dentist. Your teeth can also bleed from brushing to hard.

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!

Nothing really. It does indicate that you may have an iron deficiency. We call it pica. \n\nBe careful that you don't damage your teeth.

Because it can make the socket bleed more and delay healing, making you more prone to a Dry Socket (not pleasant)\n\nhttp://www.dentalhealth.org.uk/faqs/leafletdetail.php?LeafletID=42

Good question. Yes it's bad for your teeth to be brushed hard and that may be the reason your gums are bleeding. The other reasons could be, you have gingivitis or your toothpaste isn't good. Don't worry about having gingivitis though, if your gums are only bleeding a little bit you probably don't have it. And a good cheap whitening product is Crest Whitestrips, even though they taste nasty. Hope this helps. Bye!

Either you're brushing your teeth too hard or not often enough.  You should brush twice a day with a soft bristle toothbrush.  And floss daily.  Most people hold their toothbrush with a death grip and scrub hard.  Try holding your toothbrush with just your fingertips while brushing.  If your gums still hurt, then you probably have gingivitis.  If your gums are red, swollen, or bleeding, then they are infected.  Brush twice and floss once everyday, and rinse with Listerine or Crest Pro-Health Rinse daily also.  If you floss daily for a couple weeks, the bleeding should go away.  If left untreated, gingivitis can lead to periodontal disease, which causes tooth loss.  Periodontal disease can also contribute to the development of heart disease, pre-term low-birth weight babies, and complications with diabetes.  Take care of your teeth and gums.  Healthy gums do not bleed.  They are just like any other part of your body.  If your finger was always hurting or bleeding, you would be concerned.  You should also be concerned about your oral health.  Go see a dentist.

Assuming that the gums around your other teeth are not bleeding, I would have to say that it is not normal.  Maybe for a day or two, but not for a couple of months.  I would suggest that there may still be a piece of resing cement stuck to your tooth or maybe the crown is "less than perfect" where it meets the gums.  I think you should call your dentist to have this checked out.  Tell him/her that "no place else bleeds and this never used to bleed" and you just wonder what is wrong.  Good luck, though.\n~

you have an abcess probably of some type. it could be a periodontal abcess which is basically an abcess in the gums along the tooth you should see your dentist pronto

very possible from the numbing injection alone. There is no way for the dentist to see where every capillary or nerve is in the gum tissue when giving the shot. If the needle happens to penetrate a large vessel during penetration the dentist will see blood when he pulls back on the syringe and then withdraw it and inject somewhere else.(possible to get bruising and swelling from that too)So, if the blood supply was small, there may not be any blood when the dentist aspirates but as the medicine is placed(alot sometimes for a crown prep)this causes some tissue displacement and thus the bruising and swelling. This is just a side effect of getting the numbing shot. Very rarely is swelling and bruising from the procedure itself unless it is some kind of a extraction or a problematic root canal.

Wait until tomorrow, this is not an emergency.  Nothing will be done at the ER other than wast your time and money.\nHe has hit the tooth hard enough to cause blood to squirt from the pulp of the tooth into the dentin.  Blood has iron and that is why the tooth is changing color. Don't sweat it if it's a baby tooth.  If it is a permanent tooth he may eventually need RCT (but not always) and he may want to have something done to improve the way the tooth looks.\n\nDr. R, DDS

if its not bleeding so much then thats normal, it could also mean that ur gums are sensitive to it, maybe gumdisease/Gingivitis.\n\nHealthy gums are pink and firm, fit snugly around the teeth, and do not bleed easily. Early-stage gum disease (gingivitis) causes:\n\nGums that are red, swollen, and tender. \nGums that bleed easily during brushing or flossing. \n\nGingivitis also causes red, swollen gums that bleed easily when brushed or flossed. gingivitis usually doesn't cause.\nif you think u  may have gingivitis you may also need to check if:\nGums that pull away or recede from the teeth. \nPersistent bad breath. \nPus coming from the gums. \nA change in how your teeth fit together when you bite. \nLoose teeth. \n\nif you think you may have gingivits you mayneed to contact your dentis, and you may need to get deep cleaning (root planing and scaling)\n\nhope this helped!!

According to my dream dictionary, losing teeth means financial difficulties.As for the blood, it translates to 'Avoid controversy with friends and family."So I guess, in the big picture, be careful who you loan money to for a while.

Are you on any kind of medications? Some will make your gums inflamed. If not, then it depends on the area of bleeding. If it is in the lower front and upper first molar area you may just need a deep cleaning. If it is general and all bleed and you aren't taking any meds it could be from improper nutrition. Are you a candy and soda user? Do you eat healthy foods? Do you get proper sleep? If not, start. Your dentist can tell you for sure what the problem is by looking in your mouth and asking you a few questions. \nGo see him, healthy gums never bleed.  Oh, and you may want to invest in a water pik, they are great and can keep the gums between your teeth clean and stimulated. Floss once a day too.

Probably a cavity. Yes cavities do occur on the gumline, and no it is not dried blood from a rotting tooth! The other possibilities are: poppy seed, piece of pepper from dinner last night, or just staining.

Blood cells contain hemoglobin which carries oxygen. When blood breaks down, iron is released and causes a metallic taste in mouth. Bleeding can be from the gums, sinuses or nose. The taste can get especially bad when someone has post nasal drip and the dried blood sticks to the back of the throat. If bleeding gums are the cause there is often bad breath associated with the bad taste.\n\nAnother uncommon reason for a metallic taste in mouth is due to small electric currents in the mouth. When two types of metals are used in two different dental fillings a battery can be created. Some believe that it's due to the mercury leakage from dental silver/mercury fillings.\n\nMany oral or IV medications such as thyroid medicine, penicillin, and lithium can give a metallic taste in mouth. When someone is allergic to a specific food, the food can often be detected even in extremely small amounts. Food allergies, such as with sulfur dioxide, can also cause this. Some gastrointestinal disorders can be aggravated by food allergies and cause burping, dry mouth, thirst, rectal itching and a metal taste. High protein diets can cause benign dietary ketosis. This has also been associated with a metal taste.\n\nChemotherapy, radiation therapy, or cancer itself can cause a metallic taste in mouth. It has also been associated with B 12 deficiency, zinc deficiency, Bell's palsy, Strep throat and Sjogren's disease along with anything that causes dry mouth. \n\nhttp://www.atlantadentist.com/metallic_taste_in_mouth.html\n\nAND:\n\nA metallic taste in the mouth can be caused by infections of the mouth or teeth, skin conditions that affect the mucous membranes in the mouth such as lichen planus, or other problems, such as Crohn's disease.\n\nA metallic taste also may be caused by a substance present in the mouth. Medications that are chewed, rather than swallowed, may cause a temporary metallic taste at the back of the tongue. Other medications, such as Flagyl, tetracycline, penicillamine, Biaxin, ethambutol, biguanides, or allopurinol, can cause a metallic taste because they get into the mouth through salivary secretions or directly from the blood. \n\nhttp://www.webmd.com/hw/health_guide_atoz/not257897.asp

Teeth loose their whiteness due to age,\ncavities and eatingfood like coffee,tea,\ncola which stain the teeth.Tobacoo and \nsome antibiotics also cause stains.\nCommercial tooth whiteners use hydrogen\nperoxide and are expensive and inconvenient.\nA cheap and natural tooth whitening home \nremedy uses few strawberries but certain \nprecautions have to be taken.I found the \ninformation at http://tinyurl.com/ep7yg
