Is 2mg nicotine gum safe to use with dental implants?

I used to smoke about 10 cigarettes a day until about 4 years ago. I needed dental implants. research showed implants don't do well with smoking. So I used 2mg nicotine gum to quit smoking and underwent implant surgery. I have not smoked for 4 years. Now since the past month or so I've started smoking again. It started with one and now I get the urges to smoke and usually smoke 1 or 2 cigarettes a day. I wanted to know whether I can use 2mg nicotine gum to quit smoking now that I have implants?
