抗敏牙膏可長期使用嗎? 牙齒沒過敏,用抗敏牙膏好嗎?

沒差吧，如果買了就用，沒買不用特別買，抗敏感牙膏通常比較貴

Not recommended.

First - so called "sensitivity" toothpaste is not as effective as most believe. If you have a tooth problem, seek help instead of using this kind of toothpaste.

Second - they are generally more expensive than typical toothpaste.
