Why do people get sensitive teeth?
In nearly every case, gums have receded due to heavy-handed brushing or long-term gum disease. Either way the tops of the roots become exposed to the mouth and there is no enamel covering the roots. Think of roots (i.e dentine) like a sponge with lots of holes leading inside to the nerve. In order to sort out the sensitivity in the short term, you ought to use some kind of densensitising toothpaste like Sendsodyne. Teeth dont like to be sensitive so when they are, the nerve inside the tooth shrinks away deeper inside and lays down extra dentine inside the tooth as insulation. The problem with most people is that they brush too vigorously and the tooth wears away quicker than the nerve can shrink away so the problem remains. Remeber well that it doesnt really matter how much or how fast you brush your teeth. It simply matters that you smear toothpaste all over your teeth and dont rinse out. Hope this helps
Reply:Loss of enamel on the tooth for various reasons. Makes them sensitive to hot and cold.
Reply:There's no accounting for taste.
Reply:some people actuallly have more nerves per tooth than others, but the more common reasons are enamel breakdown and decalcification of the tooth -





braces, acidic foods, health problems - all can cause the outer layer of enamel to break down which lets the irratant (cold, heat, ect) get closer to the nerves located in the tooth
Reply:too much sugar


not brushing properly


not using mouthwash


not flossing





it may be sensitive gums...
Reply:smoking causes gum disease. the gum recedes leaving the teeth exposed. then they get very sensitive.
Reply:As people age, their enamel wears down for a variety of reasons, not taking care of teeth, acid erosion, sweets, junk food, etc.
Reply:Well first one has to rule out a cavity, a hole in the tooth, by 'paying' (pardon the pun, I know, corny :) a visit to the dentist. A cavity can turn into an absessed (infected) tooth which would warrant an antibiotic from the dentist. If a cavity is ruled out as the cause for tooth sensitivity, then it may be due to receding gums and perhaps due to brushing one's teeth too hard or with a toothbrush with bristles too hard (one is supposed to use 'soft' bristles). I use sensodyne (original formula) toothpaste as per my dentist due to my own tooth sensitivity. One is supposed to brush an up-and-down motion when using sensodyne as directed by the dr. (dr is how one addresses a dentist ;) It does help with my tooth sensitivity.
Reply:Receding gums and abrasive brushing. Use a soft toothbrush and use with soft , circular motions. Try using Sensodyne toothpaste.
Reply:gum recession, roots exposed and so sensitive, not nice.
