Mouthwash plays a crucial role in improving and maintaining oral health. When used regularly and correctly, it helps eliminate bad breath, heals mouth sores, and reduces the risk of gum disease. It is recommended to use it once or twice a day alongside brushing and flossing.

ToggleWhat Is Mouthwash?
Mouthwash is a liquid solution used to maintain oral and throat health by reducing bacteria and providing long-lasting freshness. It is commonly used to combat bad breath, treat mouth ulcers, and relieve gum discomfort. Both alcohol-based and alcohol-free versions are available. While it cannot replace brushing or flossing, it serves as an important complementary hygiene product.
Types of Mouthwash
There are two main categories of mouthwash: medical and natural. Each type serves a specific purpose. While medicinal rinses may be used for more serious gum issues, natural or herbal options can suffice for general freshness or minor discomfort. The choice should depend on individual needs.
Common types include:
- Antiseptic mouthwashes
- Fluoride mouthwashes
- Cosmetic mouthwashes
- Natural/herbal mouthwashes
| Mouthwash Type | 主要目的 | When to Use |
