I have several small white bumps no bigger than a fine point pen tip on my gum and then there is one big bump. My gums are pink, but where these bumps are that region of my gum is whitish/pale. And the side of my mouth is swollen. What does that mean
This means that you are most likely having pus in your gums which can indicate gum disease. If you are systemically healthy and have no medical complains and you're swelling has been persisting then you can start antibiotic amoxicillin 500\u00a0mg thrice a day and visit you dentist who would rule out the cause for such a pus which would be forming either due to a decay or gum disease and either of it warrants further treatment. Do not delay this further since you already have a swelling, and it may worsen the state of tooth as well as your general health.
