Root Canal - A big Pain

This post will be a biased view on root canal because of the fact that I am currently undergoing a root canal treatment and am not able to enjoy home food (which I hoped to enjoy in these holidays).

RCT is explained very well in simple language in this link

This is the second or probably third thime, I am undergoing root canal treatment and I've come to a conclusion that the treatment is not long term. The tooth on which I had my previous RCT has been badly damaged despite the RCT. The cap put up has been dislodged and is now causing me even more pains. Now the dentist had come to a conclusion that the tooth on which RCT was done can't survive for long and now must be removed to prevent infections spreading to other nearby teeth.

Even today as I am undergoing the pain of the RCT of a different tooth and the removal of my older tooth, I know that this supposedly RCT reinforced tooth will not last for long and I'll have to again visit the dentist in some years probably 3 or 4 at max.

So, why is RCT being regarded as a long term solution to teeth problems. Why is it always projected as the ultimate treatment for a damaged tooth? Weren't the older methods like silver amalgam filling and the white cement filling
( bisphenol A-glycidyl methacrylate ) good enough? Atleast, they weren't projected as a long term solution and they weren't very expensive either.
The root canal treatment is really expensive Rs.2000 per tooth at Sangli and Rs. 4000 at Pune).
Yet, because the RCT being the ultimate saviour of teeth is taken up by so many people because of the dentist's recommendation.

Actually, I feel that RCT is small part of a cycle which helps a dentist fill his pockets at every stage. The first phase of the cycle is the RCT. Gradually, the crown dislodges and because of the food entering the RC, it infects the bone of the teeth. Now, comes the next stage, the dentist tells that the tooth is badly infected and nothing can be done. The only way to relieve the pain the the uprooting of the tooth. Because, we cannot eat without teeth, we go for dentures or other prosthetic measures - (the next stage of the cycle). These are toh more costly. Again these devices come in various variants like - nickel (for middle class) and ceramic (for upper class). These devices require maintenance and we need to go to the dentist atleast once every 2 years wherein he will always find some or the other defect in the dentures and make some more money. This goes on till the end.

What I feel is that we must ensure that the atleast the 1st stage of the cycle is eliminated. We must ask the dentist to uproot the damaged tooth directly and go for artificial tooth (prosthetic devices). Atleast money to the extent of Rs. 4000 can be saved.

It is said do what you preach. But I myself have not been able to do so - Partly because the dentist is my distant relative and partly because my parents do not reject his recommendation. So, inspite of my refusal to undergo the RCT, I have to go throught the pain.
