There is no home remedy for the pain originating around the wisdom tooth, which is coincidentally considered one of the severest pains. Even if you take strong antibiotics and pain Killers they will subside the paint temporarily which is bound to recur again and that can even happened with the high intensity than the previous episode. Extraction of the offending tooth is the only permanent solution and should not be delayed till the symptoms aggravate further. An x-ray called as OPG will be required to assess the position of the root before planning the extraction. Warm saline rinses can help by slightly reducing the inflammation in the gums but it is not going to provide you substantial relief. Regards.
