Ask a Doctor and Get an Answer to Your Medical Question ASAP
Thank you for contacting Justanswer.
My name is***** khan. I am board certified family physician with specialist training in dermatology. I shall try and help you today with your query.
Let me have a quick read through and I’ll get back to you shortly.
please send me the pictures and also give me a brief back ground. how old are you? male or female? are you a smoker?
any pain burning etc currently with this spot?
Ok bear with me.
right! Ok, is this the little white spot on your lower gum on the left side that we are talking about?
does it feel sore?
Ok, This appears to be something called apthous ulcer or a canker sore.
following are the common causes for this :
I can understand your anxiety around your maternal history of cancer, however, this sore is not related to cancer. It has a very short history and a straight forward cause of you having a tooth abscess and being run down with it.
Not at all. mouth cancers do not suddenly appear overnight. you are not a smoker , which is further reassuring.
These sores can also come back from time to time due to the same factors as mentioned above. some people are more prone to it.
if its not painful you may just leave it alone, other options are bonjella gel, lidociane cream or antibacterial mouth wash that you can try to have it healed quickly.
any ulcer which is non-healing and persisting should be seen further generally. Give it about a week to 10 days.It should go away on its own.
you are welcome.
yes it can cause itching, so you might want to try the lidocaine cream or a mouth wash for that.
I hope this answers your question.
If you are happy with the response, Can I ask you to take some time to rate the consultation? Your feedback is very important for my professional growth and also for the fact that until you have rated the consultation we do not get paid for our work.
This does not mean that your query gets closed after that. You can come back as many times as you like through the thread and ask me further questions regarding this problem.
Best wishes and good luck.
thank you. have a good day.
