Totally depends on the situation. If you can turn up the power on the surrounding APs then do that, but that's rarely an option since most wireless networks are deployed at 100% power. That's certainly one of the benefits of deploying at 14 or even 11dBm, and if you did that then you should be in good shape here.

The simplest solution is to install a new AP to cover the hole. This has the downside of potentially requiring a complete recalculation of channels for your existing APs. However, if can certainly require less effort than shifting around APs. If you don't deploy a new AP, you'll need to completely shift your APs around until the coverage hole is filled, but you might open up new holes indirectly.

So deploy a new AP set to the minimum power level. If you're using CCX, mandate that the clients connect at a low power level too, otherwise they'll cause interference with the existing APs. Change channels as needed, and hopefully you don't create a domino effect and end up changing the channels on most your APs.
