A few months ago, a piece of my first molar in my upper broke off, and it turned out that a root canal treatment was required. On the x-ray, you can already see the apical parodontitis. First, the tooth was drilled and left open for a few days, and I was given antibiotics. I later received a lining for a week in order to kill the nerve. Then an antibacterial agent was placed in the tooth and will remain there for a month. If the tooth is odorless by then, the root canal treatment will be completed.
Is it possible to forgo other antibacterial linings (if the tooth is not odorless) by performing a one-time microscopic root canal? Or could – depending on the circumstances – a repeated microscopic treatment with intermediate antibacterial linings be required if the canal is severely contaminated with bacteria?
Since my dentist does not use cofferdam, does a conventional with a cost more?
Would you recommend a conventional or a microscopic treatment for a molar with normal canals? Is the investment in a microscopic treatment worth the trouble?
