Sensitivity Training

So I decided to go to the dentist a few months ago. I had a dream of whitening these otherwise dreamy teeth (thank you, braces) so that there would be no turning back. The dentist was actually insistent that (a) laser whitening was "bullshit", (b) professional whitening should be a last resort, and (c) Crest White Strips were great and are a cost-effective alternative that generally works pretty much as well as the pro treatments for most people. However, she also discovered my extreme level of dental sensitivity. She recommended a course of action: use at least one entire tube of Sensodyne F (and continue using it forever), then give the strips another shot before booking an appointment for the pricey whitening treatment. So after finishing the tube of paste a week ago, I started trying to get up the nerve to do it again.

Well, I got up the nerve. And now the nerves of my teeth want me dead. No, the pain isn't life-threatening, but it sure seems like a lot to go through just to pretty up. I'm only on day two of seven, and I've only done one of today's two treatments. That's only 3/14 of the way through! I have to do one more today and am avoiding it like the bloody plague. It's just so... gads, gads, gads, I have to press on them to stop the ouchness. I have to stop thinking about it. I have to train myself to stop listening to these icky signals. I desperately want to get through three days of this crap so that I can start seeing results and then maybe switch to just one treatment a day, but I don't know if I have the will power.
