几乎每个人都偶尔会有坏口气的经验。早上刚起床或刚吃过含有大蒜和洋葱等食材的一餐都会产生口臭。然而，有些人并不是偶尔才有口臭，而是长期为口臭所苦。大部分的案例显示口臭是可以消除的。在你决定从众多疗法中择一来消除口臭之前，你也许会想了解自己的口气闻起来如何。
检查自己是否有口臭的常见方式是对着双手呵气，然后再闻一闻。不过这个方式并不绝对可靠。比较有效的方式是舔一下手腕，稍后片刻再闻味道。如果味道很糟，你可能就有口臭。最好的办法就是找一个你信得过的人，要他∕她闻一下你的口气再告诉你意见。
形成口臭的原因有很多种。有时候只是因为食物的残渣留在牙缝或是口腔问题所造成。经常刷牙有助于保持牙齿清洁，但用牙线清洁牙齿也同样重要。对有些人来说，消除口臭是难上加难。口腔的细菌在分解蛋白质的过程中会产生不好的味道。为了消除细菌，记得要刷上颚，并务必轻刷舌根，但不要伤了舌头后方的味蕾。试试看不含酒精的漱口水，平常还要多喝水以免口干舌燥。
保持口腔清洁和口气清新是很重要的。但也别整天提心吊胆，连偶尔吃一点大蒜和洋葱都不敢。
