Is it bad or good to gargle non alcoholic mouthwash for a swollen tonsil to help kill the bacteria??

Last night i brushed my teeth and gargled crest alcohol free mouthwash and this morning it didnt hurt as bad to swollow like every other morning i would wake up it would be the worse. but just wondering if i keep doing this n maybe gargling warm salt water n drink hot stuff if it would help with clearing my swollen tonsil??
