On May 23rd, I Had A Large Cavity Filling Replaced

Question : On May 23rd, I had a large cavity filling replaced because it had fallen out of an upper tooth. My bite wasn’t correct after the procedure, though, and I went back on XXXXXXX 12th to have it adjusted. I also had to have my night guard (which I use for teeth grinding) adjusted, because my tooth was hitting it hard. Everything then felt fine after the adjustment. For a few days now (maybe since the 20th or 21st), though, the right side of the gum of the lower tooth below the upper one that had the filling replaced has been sensitive. The tooth isn’t sensitive, but the right side of the gum is. I don’t feel any discomfort when I eat but I do if I touch the gum (and definitely do when I brush the area). Also, the side of my mouth by that gum is a little sensitive (I mean the inside part of the cheek). Note that I have had mild gum inflammation throughout my life but not actual gum disease. So my questions are: Do the current symptoms (sensitive gum and side of mouth) seem unrelated to the May 23rd procedure? Should I call the dentist again or give it a few days and see if the symptoms go away? I have a five-day vacation scheduled this Friday. So I’m wondering if I should be seen before then or just wait. I’m not in any pain unless I touch the area. Should I temporarily avoid brushing the area that is sensitive? Is it unlikely this is oral cancer? I don’t smoke and have no reason to think I have cancer. I had a dental check up about a month ago. I just always worry about the worst-case scenario.
