Tongue brushing and mouth rinsing are basic treatment measures for halitosis, and as such are categorised as treatment needs (TN)-1. Although TN-1 is used for treatment of physiologic halitosis treatment, pseudo-, extra oral pathologic or halitophobic patients must also be managed with TN-1 as well as other treatments. Since the origin of physiological halitosis is mainly the dorso-posterior region of the tongue, tongue cleaning is more effective than mouth rinsing. However, practitioners should always instruct their patients on how to brush their tongues to prevent harmful effects. Another approach using a chlorhexidine mouthwash is most effective in reducing oral malodour. However, chlorhexidine should not be used routinely; therefore, zinc-containing mouthwashes have been recommended for use. People can also use chewing gum to reduce oral malodour. Surprisingly, however, it has been noted that sugarless chewing gum increased methyl mercaptan, one of the principal components of oral malodour. Mint did not reduce the concentration of methyl mercaptan either, although these products are widely used for their ability to mask oral malodour. There is a need for the development of a novel food or chewing gum that could considerably reduce VSC levels in mouth air to complement TN-1.
刷牙和漱口是治疗口臭的基本措施，因此被归类为治疗需求（TN）-1。虽然TN-1用于生理性口臭的治疗，但假性、口外病理性或口臭恐惧症患者也必须采用TN-1以及其他治疗方法进行处理。由于生理性口臭的根源主要在舌背后部，清洁舌头比漱口更有效。然而，从业者应始终指导患者如何刷牙以防止产生有害影响。另一种使用氯己定漱口水的方法在减少口腔异味方面最为有效。然而，氯己定不应常规使用；因此，推荐使用含锌漱口水。人们也可以使用口香糖来减少口腔异味。然而，令人惊讶的是，有人指出无糖口香糖会增加口腔异味的主要成分之一甲硫醇。薄荷也没有降低甲硫醇的浓度，尽管这些产品因其掩盖口腔异味的能力而被广泛使用。需要开发一种新型食品或口香糖，能够大幅降低口腔空气中挥发性硫化物（VSC）的水平，以补充TN-1。
