The primary functions of mouthwash include cleansing the mouth, preventing bad breath, preventing tooth decay, and alleviating oral inflammation. However, it cannot serve as a substitute for brushing and flossing. When using mouthwash, one should exercise moderation and strictly follow the product instructions; specific populations require medical advice. Should any allergic reactions occur, discontinue use immediately and consult a physician.

 

The main functions of mouthwash are as follows:

 

1. Oral Cleansing: Mouthwash helps remove food debris and bacteria from the mouth, thereby maintaining oral hygiene.

 

2. Prevention of Bad Breath: Mouthwash inhibits bacterial growth within the oral cavity, thereby reducing the occurrence of bad breath.

 

3. Prevention of Tooth Decay: Mouthwash may contain ingredients-such as fluoride-that aid in the prevention of dental caries (tooth decay).

 

4. Alleviation of Oral Inflammation: Mouthwash can help soothe and alleviate oral inflammatory conditions, such as gingivitis and oral ulcers.

 

It is important to note that mouthwash is not a substitute for brushing one's teeth or flossing; rather, it serves solely as an auxiliary tool for oral hygiene. Furthermore, mouthwash should be used strictly in accordance with the instructions provided on the product label, and excessive use should be avoided. Specific populations-including children, pregnant women, breastfeeding mothers, and individuals suffering from oral diseases-should use mouthwash only under the guidance of a medical professional.
