No, the same wick can be re-lit multiple times until it runs out completely. Each 3 inch wick goes on for 10 hours. The wicks can also be cut up till the used part and the remainder can be used for a fresher look. Keep in mind cutting the wick will shorten the burn time. Turning the used wick upside down and burying the solidified wax is also an option, for zero wastage while still making your candle look brand new.
