Cerec


I thought another tooth than the one that broke a couple of days was the target of today’s visit to the dentist but I was wrong. So the tooth probably felt it was about time it got a Cerec. A Cerec is sort of a filling/crown that is made from a ceramic block. The ceramic they use is almost identical in properties as the natural tooth and because of that it is extremely strong and will stay in my mouth for many decades.
The block of ceramic material is milled to the right shape in a mini robotic milling machine to the exact shape and size of the hole in my tooth. To define the shape of that hole the dentist took a picture with a special camera with 7 lenses. The computer then makes a 3-dimensional image of my tooth and the dentist forms the shape of the top of the filling on the computer screen, in a sort of 3-dimensional Photoshop application. It’s really easy (it’s done in one session with only one freezing), really fast (the whole procedure takes 2 hours) and very expensive (CAD $ 900).
Fortunately our dental insurance pays a part of that.

Diable
With the McGill Outdoors Club I went for a hike in the Upper Laurentians, about 250 km North-west of Montréal. It rains during the long drive but when we start the hike it miraculously dries and even the sun comes out. After a couple of hours we get a few showers but it is never totally awful.
And when we set up camp at a camp site, just after it got dark, and we start cooking meals on three stoves in three groups. I’m in the vegetarian group, and we even prepare a vegan meal, because one of us is vegan. While we are eating our couscous with vegetables and tofu we look in amazement to the stuff that comes out our fellow backpacker’s backpacks: someone brought a cook-set of pots with glass lids. Another thought she really needed a whole pound of butter, and we also spotted a full bottle of Tabasco.
No wonder they were so slow when going up the mountain. I, by far the oldest, and also one of the heaviest, was certainly not the slowest. Nobody even noticed that I was so much older, as they almost all asked what I studied.
