My Teeth are extremely sensitive, Why?

If you are referring to your teeth being sensitive during or slightly after you have been actively bleaching your smile, then here is the most sensible reason. Most people think of their teeth as being solid enamel structure. Actually , under a high microscope you would see your teeth are actually porous. They can and will maintain , water, stains etc. Sort of like solid enamel sponges.

As you begin a whitening procedure, these "pores" in the teeth are being cleaned from the insides out. It is very natural to feel increased sensitivity to cold sensations as well as hot. Spontaneous little "zings" are not entirely uncommon either, I do know this personally. This is a sign that perhaps the whitening procedure should be slowed down-not entirely abandoned. Hot and cold, air temperature even will be a short-lived nuisance. These symptoms do and will go away at the end of your treatment. Get excited, this is a common sign that the procedure is working to clean out the stains "inside" your teeth not just outside.

If you are referring to sensitive teeth that you have before beginning a whitening treatment then it could be due to a couple of reasons. Some people just have naturally sensitive teeth due to the fact that over the years, enamel of the teeth has thinned, -no worries- this can be a normal factor of age. Also, some people just have "thicker" enamel on their teeth.

Think- thin hair or thick hair. My concern would be that you rule out the possibility that your teeth are not sensitive because you have outstanding dental work that needs to be addressed, such as cracked or loose fillings, abrasion of the teeth(the wearing down of chewing surfaces). Please have your smile regularly maintained and checked by professionals. One tip I could give you to help with tooth sensitivity either before you've decided to bleach, or during the procedure. It may help to rinse with a fluoride mouth rinse, these types of rinses can actually cut down on sensitivity by giving your teeth a healthy boost of fluoride, tooth paste that is specifically sold to help with sensitivity is also available. These items can be found anywhere dental supplies are sold, but it is helpful to ask your dentist/hygienist what she recommends.
