Question
Am I allowed to rinse my mouth with mouthwash on Yom Kippur morning? The mouthwash has a warning on it that it should not be swallowed.
Answer
One is not allowed to rinse one's mouth with water or mouthwash on Yom Kippur. However, if you will find it very uncomfortable to fast and pray, and you add something to the mouthwash to make it's taste unpalatable, it is allowed.
