So why don't I just go and get a tube of existing toothpaste and smear that round my gums and get the same effect?

Presumably that takes a little while for that effect to be achieved, and therefore for the relief to come.

So how quickly upon beginning to use this would I, if I had sensitive teeth, begin to see a benefit?

And is is that what it is?

It's just used as a toothpaste.

So instead of using your normal brand, you would use your product and get the effect, or do you need to use this as an adjunct to existing tooth cleaning regimes?

How does a maxillofacial surgeon end up playing around with this stuff?

How did you stumble upon how to do this?

And it's completely safe.

There there are no health problems, it's biocompatible, you can put this in the body, no problem.

It really is an example of science meets art this, isn't it?

What does your brother say, having given you the idea?

Noel Kent, who's an oral maxillofacial consultant and also co-founder of Ozone, a new aerogel-based way to treat sensitive teeth.

Well that's it for today.

I did promise you last week though that I was going to report back on my taste test of Savour's Artificially Made Butter, which we talked about in a previous programme on Foods of the Future.

Do check that out.

It was a great listen last week, even if I say so myself.

The sample did eventually arrive, and I tried it on a bit of baguette.

It looked and tasted just like a pale butter.

In fact, I wouldn't have known it wasn't butter if I hadn't been told.
