Wearing Flipper after bone graft and dental surgery. Any suggestions?

I had an implant and bone graft done at the same time 2 weeks ago. I have been wearing a flipper previously to keep the space open. I am a bit paranoid that my teeth around the space have been moving. My surgeon made the tooth on the flipper a bit smaller. It doesnt hurt when it is in but I don't know if I should wear it for long periods of time. Will it damage the implant healing process? I notice when after immediately after taking the flipper out it hurts to swallow the first couple times.
