Dentistry/Dentin hypersensitivity / enamel recovery?


Dear Howard,

In 2012, I asked you a question about my case which is dentin hypersensitivity as a consequence of tooth brushing with some soda. You answered that question here ( advising to use a desensitizing toothpaste. I have been doing it so far and it moderately helped, yet, I still have this sensitivity and sometimes it is really disturbing.

I am wondering if science and medicine have gone further in this issue of dentin hypersensitivity since 2012; if any techniques of enamel recover have become available since then? Do you know anything about that or perhaps you know where I could search for more information?

Thank you very much in advance for your answer.


Dear Sam,
sorry to hear you are still having sensitivity.
To my knowledge there is no enamel replacement or grower, despite what you might read.
The best advice I have is stop brushing the teeth for a week and see if that helps.
Although it is counter intuitive advice you might be very surprised to discover that the combination of dental plaque and saliva may be the only non-surgical solution to your problem.  Also during the week trial , chew gum, three or four times a day  it will stimulate salivary flow. The saliva is the only source of mineral for rebuilding and protecting your sensitive teeth.
Hope this helps a little , if not then your only alternative is dental intervention.
All the best,
Dr. Moss
