Yesterday, I felt a sensation in the back tooth with the large cavity that you had seen earlier (molar, I believe, which was pictured above in my post on April 26th). To be precise, the feeling was in the gums. I felt it after I drank something cold (and the same when I eat certain things), and I felt the sensation continue until I used an antiseptic, at which point the sensation subsided significantly but not entirely. Does this indicate that the nerve is damaged?
Also yesterday, I talked with my doctor about that back tooth and she suggested drilling into it to find out. Does this sound like an appropriate approach to you, given the trickiness of having 4 nerve canals in a molar? In other words, is it necessary to drill the tooth because of the difficulty of identifying damages to the nerves?
Lastly, would be okay to ask where your practice is located? If not, no worries. Thanks again for your thoughts.
