Unhappy with dental plate but what can be done?

Q. Hi I have 7 implants at the top of my mouth. At the moment we are only useing two of them, but unfortunately i am unhappy with the plate I feel that they are not right on one side and they make me look funny, also they tend to ache a lot is this normal. When i had them done i thought my sinus had been damaged as my nose kept running, this has subsided but still taking nurofen plus quite a lot for dull aches etc. Unfortunately i do smoke but do my best to cut down and to keep my hygene up to scratch.
