Due to the current Covid-19 scenario, it is quite obvious and rational of clinics to charge extra for consumables items like PPE, understand that it's for your own safety. Expect a price hike of upto 2000 on your usual RCT charges, at a well - equipped, ideal clinic with specialist consultants, expect charges upto 8000 for single-sitting RCT
Next Steps
I suggest you get a post-RCT permanent filling done atleast, and then you can wait to get a crown
Health Tips
you are NOT advised to chew on a RCT treated tooth, as it may fracture
