Why does my tooth pain get so much worse after each antibiotic dose?

Secondary infection at the site of a few month-old root canal in a back molar. Infection caused by bruising from a bite occlusion (teeth shifted). They ground down the parts that were hitting. I'm on antibiotics (amoxicillin) three times a day, which I've been taking for four days now.
Every time I take my antibiotics, the pain flares up about half an hour to an hour later. I thought it was from chewing during eating, but I don't always take them with food now and it still happens. I missed my morning dose today and didn't have as much pain. Took my antibiotics later in the day and the pain flared up shortly after. As of today, I'm also on Vicodin for the pain. It has helped, but the flare up still happened after the latest dose of antibiotics.
I'm not looking for medical/dental advice. I plan on following my dentist's instructions and saw him earlier today because the pain had gotten worse (turns out they hadn't gotten everything adjusted properly last time). It's really just a curiosity thing, because I've always had an armchair interest in medicine and biology. It seems like a weird thing to happen. I'm just wondering if it could really be the antibiotics causing this, and if so, what is the mechanism for why it does this. When I search online, all I find is how antibiotics are used to treat flare-ups of dental problems, not the opposite.
