A crown, or, cap, is used when a tooth has worn down or to prolong its life if it has a large filling.
I certainly did not realise that a crown could make a tooth last longer. I also wrongly believed that having a crown made you needed a root canal filling. This is not the case.
A tooth with a large filling in the middle will have two cusps, front and back, which are liable to crack off. This is because of the pressure down on the filling from the tooth above, which tends to spread the filling, pushing the cusps outwards. I had a number of teeth with large filling – a remnant from childhood when dentists seems to drill big holes in all your teeth.
When you have a large filling in a tooht, by having a crown which completely covers the tooth the pressure from the tooth above is absorbed by the crown, protecting the underlying tooth. This makes the tooth last longer.
As it is my aim to live to be at least 150 I need to have my teeth lasting as long as possible. This certainly makes it a longevity issue – and so a suitable topic for this blog.
My second trip to the dentist a couple of weeks later was to have the crowns fitted. I knew what to expect now so was not as apprehensive as the previous time.
The crowns had been made and they were sitting there fitted to a copy of my jaw.
Removing the temporary crowns from my teeth seem to require a huge amount of pressure to me. But it was not painful, and I suppose the glue used has to be quite strong so they don’t fall out before the patient returns.
Fitting each new one in place was a long job, longer than the job of fitting the temporary crown.
The fit is incredibly precise, and I was glad I was in the hands of a specialist in this area. I suppose the crowns are made slightly oversized, and then the trims them very slightly so that there is a perfect fit. She chopped off bits here and there, drilling off tiny pieces to make my bite absolutely perfect. She then checked it four or five times each side for each of the two crowns.
Eventually, she was happy, and I was happy. The necessary filling was done to a back tooth, and then it was just the extraction of the broken tooth to be done.
For the extraction, I was ready for quite a fight to pull out this broken tooth, only a small piece of which protruded above the gum line. In the event, I felt absolutely nothing.
I was stunned. The dentist fiddled about for about five minutes sticking something down into the gum, then out came the broken root. I felt nothing! I could have sworn that removing it would involve more discomfort than that. She assured me it should not.
Now I had to wait a few months for the bone to heal whether rooted come out. I would then have a visit to a surgeon who would assess how best to apply the titanium pin into the jawbone which would hold the implanted tooth to fit in the space. The ideal time to leave this was between three and six months, to heal up.
I emerged from dentist feeling a little bit number than the previous time, but still not too bad.
I still felt that I was in excellent hands, and did not regret my decision to proceed with this expensive treatment.
I approached my first proper treatment with a little apprehension. I knew it was going to be two or three hours long, and that there was work to be done on both sides of my jaw. I could see me walking out with no feeling at all in my mouth.
You will remember I was to have two crowns fitted, a filling, and the removal of a broken root.
One thing you get in Harley Street (at least in this surgery) is a flat-screen TV fitted to the roof above your dental chair, and the remote control in your hand. This was a first for me!
During this first treatment temporary crowns were to be fitted. This dentist is a specialist in this area.
The injections were fairly painless. The dentist worked on the teeth to be capped shaping them to receive the crowns. She would fit temporary crowns to the teeth once they had been shaped so that they were ready to receive the proper crowns once they had been made.
After 2 1/2 hours I emerged with all the shaping work done, and temporary crowns made in the surgery, and fitted. It was noticeable the great amount of care that went into creating the temporary crowns and ensuring that they did not interfere with my bite.
The anaesthetic was not quite as strong as I had feared, indeed it was nothing like as bad.
I headed for the train and the hour-long trip home.
After a week I received a detailed plan of recommended treatment from my dentist. I had explained that I would not be doing everything at once, and so she prioritises the treatment to do the most important first.
One tooth had broken off a cusp and so obviously needed doing quickly. Another tooth had dropped out having had a broken for a few months. My previous dentist said wait till it falls out. Unfortunately, the tooth had become infected in the meantime and was oozing pus. Yuck! Probably a bad call to leave it so long.
So, removal of the root was also a high priority.
The two is next to the broken root had a large filling which was disintegrating. This was also prioritised for early treatment. Finally, back to is have a chunk which have fallen off, and so this was going to be repaired.
This was the initial treatment. The total cost was lower than it might have been because of who recommended me. The first chunk of treatment worked out at a total of £2750.
Having arrived at the dentist in Harley Street I went through the then a thorough examination. The dentist was very pleasant and friendly and made me feel completely at home.
After the consultation she took me through her findings. These were made much more comprehensible by the use of photographs. It was incredible to see excellent photographs of my teeth as she explained what was going on.
I have mentioned before that the photographs showed decay all-rounder large filling which no previous dentist had mentioned to me. This had obviously been going on for quite a while, and needed sorting out.
This alone was enough to convince me that I have come to the right place. Added to the strong recommendation of someone I trust, my decision was made I would certainly trust this person and go through their recommended treatment.
It is quite expensive, though, so I would spread it out over the course of a year.
Ray Kurzweil says that scientific advances are happening faster and faster. He points out that whereas evolutionary changes used to be very slow, it is in their nature to accelerate. Ten years ago hardly anyone used search engines! Ten months ago hardly anyone used Twitter!
These accelerating changes will make for more dramatic changes in the next few decades than most of us can imagine. With Kurzweil’s help, we can get a flavour of what these changes will mean for us.
As always, this interview with Ray Kurzweil is fascinating.
I have been going to what I considered was a good dentist for a couple of years for my dental treatment. A month ago, he said that one of my teeth was heading towards needing a crown. A cusp had cracked off and he said just to leave it.
Let’s face it, it is tricky to decide on a healthy diet. (It is even trickier to stick to your healthy diet!)
I like very much the intelligent and considered approach of Michael Eades MD to, among other things, healthy diet. As I do, he believes a high carb/low fat diet is neither good for health – nor for the weight reduction for which it is often adopted
In this blog post, Michael Eades displays a YouTube video of a Stanford University researcher discussing the merits of four popular diets. He then discusses the recorded analysis at length, making clear his own well thought out views.
The four diets discussed are the Atkins diet, the Ornish diet, the Zone diet, and the LEARN diet.
This is a chunky post! But if you are prepared for a long watch (YouTube), and a longish and intelligent read, you can learn tons about the best diet for you from a thorough read of this post.
I will certainly be keeping an eye on Michael Eades’ blog from now on. Very interesting and well informed.
Genius Ray Kurzweil has long predicted the time when a computer will be able to think at the same rate as a human.
He predicts that this time – which he calls the Singularity – will occur around 2045. It will have tremendous repercussions for humanity. Kurzweil explores the Singularity on this video.
