One of my gums was swollen for a few days, when it came down, there was this white little bump on it. What is it?

I don't smoke nor drink, unfortunately due to the pandemic, I haven't been able to go to the dentist for checkups. I feel neither pain nor fever, I have no loose teeth,

and there's no bad taste in my mouth. What is this thing? Is it an abcess?

Good day
This could be the draining sinus of an abscess. Sometimes a tooth can have a cavity in between the teeth that you can't see. A draining sinus also prevents a pressure build up, and this might be why you aren't experiencing any pain. For a better evaluation, a x-ray of your teeth will be required. Best to make an appointment with your dentist. You can try rinsing with some saltwater in the mean time.
