I have been getting tooth pain whenever I drink cold/normal water. I usually discuss these things with my friends. One of them suggested to use Betadine Gargle for a few days, saying it helps remove any particles stuck around the tooth. He also mentioned that he uses it every night before going to bed.
When I asked why regular water wouldn't be enough, he said, “Can you remove dirt from clothes with only water? You need detergent.”
Based on his advice, I bought Betadine Gargle and started using it. After using it, I felt a lot of relief.
