Wisdom teeth pain

Hey y’all I had my wisdom teeth taken out in 2015. I occasionally have pain back there or it will feel sore. The only thing that seems to make it feel better is massaging the area but that obviously isn’t always an option. I also have an area of the left side of my mouth where I thought a filling had came out but apparently there never was one there. That affected part also will hurt and get sore. I did see the dentist and was told to use a mouthwash for sensitive teeth twice a day. My mouth is hurting pretty bad right and now and it’s making my cheeks swell a bit. Is there anything else I should try until I can get back to see the dentist?
