This Sensodyne toothpaste that contains Novamin which is supposed to renew the teeth's enamel coating...
Personal experience. Previous visit to dentist I mentioned some sensitivity to cold foods, dentist recomended using Sensodyne, I did.

Of course it could just be the change of toothpaste to one less abrasive or any other change related to the toothpaste, different Ph?

Basically, on your teeth, under the enamel, are tiny channels that goes through to the nerve area. If the enamel gets worn down, or you have receding gums, these channels get exposed and you have a quick path for hot/cold/sweet straight to the nerves, which are very sensitive [1]. Once the nerves get hit once, they for some reason become super-sensitive.
What the Sensodyne stuff contains is some chemicals that can block these channels, allowing the nerves to calm down. And yes, it can take several weeks to desensitise them.

And since they are shielded with great chunks of teeth, they have to have the gain turn way up.HomeOwnersHub website is not affiliated with any of the manufacturers or service providers discussed here.
