yes,it is advisable to remove the wisdom tooth.In your case since it seems to be in a position where it is causing food lodgement which has led to a carious lesion in the front tooth,its better to get it removed before the crown preparation in the front tooth is started,
Next Steps
Get the tooth removed as soon as the root canal treatment is done,before the crown preparation is started.I will take about two weeks for the gums to settle down,once they do,its better to get the crown preparation done.
