**How to choose the best description:**

* **Consider your audience:** Who are you writing for? Are they general readers or more health-conscious individuals? This will help you determine the appropriate level of detail and tone.
* **Think about your blog’s focus:** What specific aspects of oral hygiene do you cover most often? Reflect these in the description.
* **Keyword optimization:** If you want to improve search engine visibility, consider including related keywords (e.g., 刷牙技巧 (shua ya ji qiao – brushing techniques), 牙刷品牌 (ya shua pin pai – toothbrush brands)). However, keep the description natural and readable.

I recommend **Option 2 or 4** as a good balance of detail and clarity for most WordPress blogs. Remember to replace the placeholder text inside the descriptions with your own information! Remember to add these descriptions in the tag descriptions field in WordPress.
