It could be that is really a minor issue right now, something that is asymptomatic and will only progress slowly. Could be at some point in the future you may not be in as good health overall, and unable to go to the dentist. Murphy's Law says that is when that minor issue will turn into a major issue. Fix it sooner than later. Small problems require small fixes that are usually easy to do, not very painful or expensive. Big problems take big fixes that are much less fun, much more expensive, and might not be as successful. Do it sooner as opposed to later.
