saliva is not just a liquid in our mouths; it plays an essential role in maintaining our oral health and overall well-being. 🦷 Firstly, saliva helps to break down food particles, making it easier for us to digest our meals. Secondly, it acts as a natural cleanser, washing away bacteria and food debris that can cause tooth decay and bad breath. Additionally, saliva contains enzymes that help prevent infections in the mouth. Lastly, it keeps our mouth moist, which is crucial for speaking and swallowing. In essence, without saliva, our daily activities would be much more challenging!漱口水不仅存在于我们的口腔中，它还在维持我们的口腔健康和整体健康方面发挥着重要作用。牙齿是我们口腔中的重要组成部分，唾液帮助分解食物颗粒，使我们更容易消化食物。此外，它还起到天然清洁剂的作用，清除可能导致蛀牙和口臭的细菌和食物残渣。唾液中含有的酶还有助于预防口腔感染。最后，它保持我们的口腔湿润，这对于说话和吞咽至关重要。简而言之，没有唾液，我们的日常生活将变得更加困难！
