Thanks for posting your query,
there are a few things that a pain sufferer can do to bring temporary relief. Rinsing the mouth with warm salt water, germ-killing mouthwash, or peroxide-based mouthwash may help people who have pain that seems to be caused by an infection. Rinses and mouthwashes can usually be found near the toothpaste in a grocery or other store.
If tooth decay
has caused any cavities, or if fillings have loosened or come out entirely, tiny particles of food may become lodged in these areas, leading to pain.
Taking an over-the-counter pain reliever can be helpful as well.
Gels or drops designed for mouth pain are good options as well.
I hope this information has been both informative and helpful
