Experiencing tooth sensitivity a week after i had two fillings replaced. is this normal or am i experiencing this sensitivity due to my receding gums?

Most likely fillings: If your sensitivity started or worsened after the fillings were replaced it is most likely not the receding gums. This Can happen when using white filling and is related to many issues regarding the depth of the restoration, the technique used or the material itself, some time a simple adjustment of the bite can solve the problem. Go back to your dentist .

Tooth pain: Absolutely expected It shoul get better as time goes on. If it doesn't or gets worse see your dentist again

Sensitivity: Working on a tooth can cause inflammation in the pulp or nerve and blood supply within the tooth. in most instances our bodies respond very well and experience little to no sensitivity post op. some instances where the fillings were deeper, or larger could result in more inflammation that could take longer to subside. if the bite doesn't feel quite right you want to go back and have that fixed.

Be patient: Some people feel sensitivity after they receive a filling. In most cases, the sensitivity will decrease over two to three weeks.
