but my problem isn't from decay or bulemia... it's from only TWO DAYS of crest whitening strips. needless to say, i ditched them, but my teeth are really sensitive now %26amp; it hurts to eat or drink anything :[





so tell me once %26amp; for all, if it's only from the cause i mentioned, will the surface enamel grow back or get stronger or whatever it does? i'm worried :[

Does lost enamel from tooth-whitening products come back?
The whitening strips actually do have bleach in them. Your teeth are made of carbon, and bleach is like acid on carbon. Your teeth have been weakened by the strips - but for it to have happened so quickly means that your tooth enamel was already thin. You may be one of the people who can use fluoride to help your enamel regenerate. Fluoride is known to sometimes encourage the cells to grow, but it doesn't always work. Try using fluoride toothpaste every night before you go to bed, and use a fluoride rinse afterward without drinking or eating before sleep. It may take many weeks for it to help - it only took me about two weeks to lose sensitivity, but I had prescription strength fluoride toothpaste. Teeth can look yellower when the enamel is weak and when you haven't been brushing your teeth. Make sure to floss and brush before bed every night from now on, and don't use whitening products or toothpastes that claim they can fill in cracks (they'll only prevent the fluoride from getting to the enamel cells).





Oh, and make sure to brush your tongue, too. The tongue can harbor bacteria and food that migrate to your teeth during the night and break down tooth enamel.





The remineralizing is myth. It's the cells that regrow. And yes, they can regrow. It all depends on your genes.

Reply:You didn't lose enamel when you use whitening strips.


Your sensitivity could be due to several different things. Overuse, are you using for longer than suggested time?? Do you have decay on your teeth??


Your teeth may be dehydrated by the strips. Take 200 - 400 mg of ibuprofen. If you have a fluoride rinse, you should use it. The sensitivity should be gone by tomorrow.


You might try the strips every other day...instead of every day

Reply:sadly, no. enamel doesn't grow back.





enamel is of epithelial origin and it is made from a type of cells called ameloblast.





these cells lay down enamel in microscopic layers from the core of tooth and move outwards. hence it is always on the outermost surface, these cells eventually die off and were rapidly removed when the tooth erupt into the oral cavity.





without these cells, it also mean that lost enamel will not grow back.





sensitive tooth suggest that the yellower 2nd layer, called the dentine is exposed. the dentine have a tubules-like microscopic feature. u felt sensitive because of osmotic movement of water into and out of these tubules which have nerve endings in close proximity to them. especially when ingesting hot/cold stuffs.





you may want to change the toothpaste that you were using to those types specially for sensitive teeth, like sensodyne.





this type of toothpaste is less abrasive and have ions that have plugging effects on the dentinal tubules to relieve sensitivity.





unlike enamel, the wonderful thing is that our body can build more dentine encroaching into the core of tooth, called secondary dentine. after a while you may feel less sensitive as secondary dentine build up.
Reply:Its not by the lose of enamel that you are having the sensitivity. Almost all tooth whitening products can cause this. When wearing be it strips, trays what ever you use don't use as long. By brushing with flouride like Act or a Dentist has a prescription type toothpaste called prevedent that will help with the sensitivity. Just slow down with the whitening.
