Thanks for posting your query.
From what you've explained, I presume that you have a decayed tooth on your lower left side which could be the cause of your pain.
Did you visit a dentist? If so, were antibiotics and painkillers prescribed by your dentist? If an xray of the affected area was taken, can you upload a photo of that xray?
If you have not visited a dentist yet, I advise you to visit one immediately. I understand that you may have a deacyed tooth with an abscess
. This means that your tooth has a decay which has reached the pulp and has got infected. Long standing tooth decay
leads to losing the vitality of the tooth [tooth becomes dead in layman's terms].
This in turn causes abscess formation in the root area, which you're seeing as a white spot in your gums. In a few days, there might be sinus
formation (opening) in the bone as the pus tries to drain out that way.
Your dentist may advise you to take an xray. Based on analysis and severity of the infection, you may need a root canal treatment
or the infected tooth may even need to be extracted out.
I hope your queries have been answered.
Take care, and wish you good health.
