A 36-year-old male asked:
Ive been using 3% hydrogen peroxide with half parts water, once a day, for weeks, as mouth wash after brushing my teeth. i now have sensitivity at the tips of a few teeth when chewing food. if i caused enamel damage, can my teeth heal over time?

The teeth are not damaged...You have had penetration of the hydrogen peroxide into the pulp of the tooth causing some microscopic bubbles there and when they expand and contract due to temperature changes with food and drink it causes the pain you are experiencing. You can discontinue for a week and see if that helps..could also have gotten there from some areas of receded gums..

When used correctly, small amounts of hydrogen peroxide are safe and effective. Higher percentages of hydrogen peroxide are often used professionally to whiten teeth.. The amount of peroxide you are using really shouldn't hurt your enamel. You can't restore enamel as it is "dead tissue." You can reinforce enamel by a process called “mineralization." Try the Sesodyne products for your sensitivity.

May be , you have exposed dentin
due to presence of decay or fractured teeth .Stop using peroxide
