Excellent dental treatment for emergency root canal from a medical perspective, but despite pleading for nitrous to be administered Dr Chasen kept insisting it was not necessary. When multiple shots of novocaine proved insufficient and I had literally grabbed his arm to pull it out of my mouth several times, he finally relented. The results were excellent and utterly professional, but my own personal experience from a pain and fear perspective was quite horrible. If you suffer from dentophobia, you may want to consider my regular dentist - Dr Daniel Tseng of the Danbury Dental group who has performed root canal surgery on me previously with a far better experience but was unable to take me at short notice and referred me to Dr Chasen.
