How come after you brush your teeth, water is extremely cold tasting?

this is purely because of the presence of the mint in toothpaste. this menthol in toothpaste makes the mouth numb by which the water or anything is felt too cold. you can even test this too. \nif u brush ur teeth with something else. say with salt or some other farooky or dabur danthmanjan, you will not face that. \nin the same way, eay polo and then drink water, u will face the same experience. \n\nthis clears shows that this is only because of the menthol in the toothpaste.

it's frostbite. the water melting off the ice cube is because salt lowers the freezing point and so the water on your skin is very cold <32 so it freezes the skin. kinda like making ice cream except more painfull

Strangely enough, the HOT water would freeze first.  There is a chemical explanation for this.

If your going in for a cleaning, I'm sure when they take the x'rays the Hygienist will find your problem with your molar. Get it treated as soon as possible, before a Root Canal, comes knocking! \n\nAs far as sensitivity is concerned... the cold water, might give you a good jolt! Good luck on that, there isnt anything we can do about it. We dont get options in offices when it comes to hot or cold water. We ONLY get cold. Sorry..... \n\nGood Luck...

There are number of causes for a metallic taste in the mouth. The most common causes are as follows:\n1) Oral problems: when blood breaks down iron is released and causes a metallic taste in mouth. common causes of bleeding could be gingivitis or periodontal disease (gum disease), it could also be from sinuses or nose. If the cause is the post nasal drip tastes can get specially bad. Metallic restorations like amalgams (silver fillings) could be leaking and breaking down have your dentist check them and if you have older silver fillings have them replaced with bonding, porcelain veneers http://www.nwsmilespecialist.com\n\n2)medications: \nAmong the drugs that can cause a metallic taste in your mouth are antibiotics like Biaxin (clarithromycin) and Flagyl (metronidazole), used to treat a wide variety of infections; drugs used to treat an overactive thyroid; captopril, used to treat high blood pressure; griseofulvin, used to treat skin infections; lithium, used in bipolar disorder; penicillamine, used for rheumatoid arthritis, kidney stones, and too much copper in the body; plus some drugs used in cancer treatment\n.http://www.drweil.com/drw/u/id/QAA350574\n\n3) Impaired taste (Dysgeusia): common causes of impaired taste are:\ncommon cold, nasal infection, nasal polyps, sinusitis, salivary gland infections, influenza, viral pharyngitis, mouth dryness, aging, vitamin B-12 deficiency, gingivitis, bell's pasy, sjorgen's syndrome, strep throat\nhttp://www.nlm.nih.gov/medlineplus\n\n4) Excessive copper intake:\nExcessive copper intake can cause nausea, vomiting, stomach pain, headache, dizziness, weakness, diarrhea, and a metallic taste in the mouth. Copper toxicity is rare but can cause heart problems, jaundice, coma, and even death. \nCopper overload may occur from using copper cookware and from water supplied by copper pipes on a regular basis. Copper can leach out of pipes into water, especially hot water, if it sits in copper pipes for an extended period of time. It is best to always cook with cold water. Flushing the system by running cold water for 2 to 3 minutes is an effective way to reduce copper. Also, it is best to avoid unlined copper cookware since copper can leach into acidic foods such as vinegar, tomato, or citrus. If you have blue-green stains around your faucet or sink, or if you detect a metallic taste to your water, you may want to have your water tested by a certified laboratory.\nhttp://www.umm.edu/altmed/ConsSupplements/Coppercs.html\nBest of luck.

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

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.

Your mouthwash might be irritating the insides of your cheeks.  Usually mouthwashes have a high concentration of alcohol.  I have to dilute mine with water whenever I rinse. You should also check and see if your toothpaste is irritating you, too.\n\nTry stopping the mouthwash and see if you stop sloughing. If not, then, it's your toothpaste.\n\nNothing to be overly concerned with. Just switch toothpaste brands to see which one works the best.

water doesn't actually repel from toothpaste.  It is absorbed.  The toothpaste absorbs the water very quickly, making it disappear.  This looks like the water is repelling from it, but that is just an illusion.\n\n\nIf you look at the ingredients in toothpaste, the first one listed is water.  If toothpaste repelled water the toothpaste would separate itself in the tube, which would lead to you brushing your teeth with nasty gunk.\n\nSorry for the wordiness, I did my best.

As in Alaska -- the moisture from your nose and mouth can crystalize as they escape from your mouth when speaking outside in the sub-zero temperatures.

yes it is possible to have that removed from your water by reverse osmosis.\nI dont know how you can stand the taste of your water.\nYea, that sounds bad to me also.  Get yourself a good filter (not the cheap kind) for your sink, it's cheaper in the long run than bottled water.  Get the filter which filters down to the smallest micron and that's about all you can do.  Best Wishes!

Don't flavor it. Our bodies have specific taste buds in our throat that taste pure water. After a few days of drinking water, you will learn to appreciate that flavor. And as other answerers said, the temperature of the water will make a difference. Some people like it ice-cold, some like it tepid. If you want to buy water to get the purest, some brands you might like are Dansani and Pellegrino, they have some natural minerals in them, which make them taste both pure and flavorful.

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

I would say drink more water. Do you rinse your mouth after brushing your teeth? (if you brush before bed). Do you have any teeth problems.? do you eat a lot of sugary things before bed? That would coat your tongue.

Movies make out that the tounge is stuck for good.  A couple examples: "A Christmas Story," and, "Dumb and Dumber."  But you just need to exhale heavily and the tounge tip is defrosted.  It still isn't good for the tounge so it is unadvisable.

The whole reason to brush your teeth in the first place is so get rid of plaque and bacteria. By that, if you brush before you eat you're getting rid of germs, then by eating after you brush you're only inviting more bacteria to grow until the next time you brush. The bacteria is what makes your breath smell bad so....you should definately brush AFTER you eat in the morning. Any dentist will tell you the same.

Once you are over the cold, dispose of the toothbrush. Also, you should change your toothbrush frequently during cold and flu season to keep from getting sick.
