Sir,
I have doubt in my mind -
Eight month before I have gone under root cannel treatment of one of my teeth and after the one month of RCT my TWO teeth were covered with Nikil cap. The cap was uncomfortable (infection was developed in one gum) and the cap was removed after the three months and infection in gum was continue till December 09.
Since last 6 month my health is detoriated
I feel pain in stomach when touched / ESR is 70/very weekness/Lamellar pleural effusion on left side.
Now Sir, Please reply,
1. Whether teeth (RCT teeth) infection may cause stomach pain and may increase ESR level up to 70/Pleural effusion (Reason for/ doubt --because after one month of RCT my stomach trouble started and continuing.
2 Can nikil metal cap is harm full as it has spoiled my third tooth
3. Should I immediately go for removal of thhe RCT and infected teeths.
.

You need to see a medical doctor and have your stomach problems assessed. It could very well have nothing to do with your tooth but is just a coincidence.

Infections in your mouth can cause all kinds of systemic issues.

I have had stomach pain due to a severely infected failed root canal. I also had many other symptoms due to the infected tooth and root canal. After taking antibiotics and having te root canal retreated, the symptoms quickly vanished. A tooth or gum infection can cause many secondary health issues, including death.
