Patient discussion about pit

Q. What are the dentists going to do if I have Pit and fissure caries? I look at my teeth and i see tiny black stuff on the fissures of my molars. I am so freakin scared. Are the dentists going to do something painful?

A. Well you will have to see a dentist if you want an answer on what kind of treatment they will offer you. Today dentists use good anesthesia so anything they will do is not supposed to be painful.

Q. tender protuding lymph node lump rt. arm pit aprox. 1/2" dia. any concerns or recommend treatment necessary?

A. lymph nodes can flare up any time you get infected in the armpit and all the area that it drains. i had it several times and it went away in the same manner that it came. i think that sometimes it caused because of a blockade done by deodorant. so i try to use this Chinese salt stone that doesn't contain aluminum.
