An upper molar is very painful and gums are swollen around it. clindamycin was perscribed, is this an abscess? - clindamycin gum

Dentist offers a root canal treatment or extraction. I am trying to extract because of the costs and the molar is missing in the other side of my mouth, so that the difference is to see if I will smile, what are the disadvantages of mining? I have about 12 root canals / caps. Thank you for any input
