Do not let it be. Get it fixed now, while it's small. The drilling will be less invasive, you'll need less of the terrifying pricky needles with painkillers, and more of the tooth will be intact to withstand the ravages of time -- because I'm starting to think that once a tooth has a filling it's only a matter of years before it degrades further, I'm sorry to say; there's no perfect way to keep bacteria and decay out of the joint between enamel & dental work.
