I want to know which of my tooth is infected. I am sending my latest x ray. Is there any infection in first molar or second molar tooth or in both. Is my last molar in mouth is infected. If i go for rct then it will become dead tooth. And if i lost both of my molar then it will be problematic for me to chew from that side. Please suggest me for which treatment i want to go for. My first molar is in need of some kind of treatment. Is the cavity in my first molar (last molar in my mouth) deep into my pulp. Is there any other solution of this problem. I dont want to loose both of my molar tooth.
