1. I had my tooth # 20 totally decayed. 2. #20 got removed and bridge work was suggested. 3. once my #19 and #21 were ground for bridge work, it seems i am being thrown to get root canal done on 19 and 21 before the bridge work. (remarks - my teeth are small and structured this way) 4. I feel angry now that i have two of my natural teeth are tampered. 5. Is this normal when bridge work is done? Need a second opinion
