Getting a second opinion from the dentist

geek84

Good Morning Folks 

My dentist says I need to have one of my back teeth (I presume it's the wisdom tooth) removed.  However, I'm not so sure and would rather have a 2nd/3rd opinion. 

Do you think I should register with another dentist in order to get another opinion?  How would I choose which dentist to join?  

Should I then go to the new dentist and just simply ask him/her for a 2nd opinion or just go for a regular check up and let him/her tell me that I need to tooth removed? 

Thanks in advance
