My little sister has a tooth that needs a root canal, that is affecting the teeth near it and she's in constant pain. She also needs several tooth fillings. I took care of 2 fillings today, tooth 19 and 20 in the picture. She still needs about 7 to 8 more. 3 on her lower right, 4 on her right upper side and the tooth that needs a root canal on the upper left also 1 cavity in the upper mid section. Currently we are focusing on the teeth that needs a root canal and any help would be very appreciated. God bless you and Happy holidays.
