Question: Hi. I saw an Endodonrist nearly 3 weeks ago after tooth pain/Infection. I had a root canal procedure earlier in the year on this tooth. The Endodontist recommended the root canal be done again so he did the procedure immediately. Pain virtually went away. However the guy area above this tooth has now become sore and a small blister has developed. I have started to take antiseptic mouthwash Curasept but is there anything else you would recommend? I took a course of Metronidazole before and during the treatment. Would you recommend some further antibiotic like Amoxicillin to heal the gum? Not sure what would cause the gum soreness. I’ve also seen a dental hygeniest.

This is Dr. Priyanka tiwari answering your query.

I have read your query and understand your concern. As far as soreness and blister on gum is concern after root canal therapy this can be due Periapical or Periodontal infection.

Can you upload the picture of gum blister that would be more helpful for me to give you proper dignosis.

Inmeantime i would suggest you to maintain good oral hygiene.
- You can take medicine like Amoxicillin with metronidazole by consulting with local doctor.
- Take Cap. Vitamin b complex once daily.
- Avoid hot and spicy food.

Awating for pictures to comment further.

Hope this will help you.
Thanks and regards.

i went to the dr. yesterday for sore throat, body aches. was told it was not strep but viral infection. she did notice a pus pocket on the right side of my throat, I was prescribed antibiotics (Z-pack) for 5 days. My dr told me to gargle with salt / warm water. My question is should I try to remove the pus pocket myself with a q-tip, as that is what I have been reading online that several people remove the pus pocket with q-tip.

Hello. 3 days ago, I had a short-lived stomach virus,around 24 hours long, and vomited a total of 21 times, causing me to lose some weight and become dehydrated. Ever since then, I have had this continuing bad taste in my mouth. I tried drinking a lot of water, brushing my teeth and tongue constantly, and using mouth wash, but it doesn't seem to work. Originally, the bad taste originated in the left side of my mouth, along my tongue, and now it has spread to my entire tongue. I thought it may have been oral thrush, but I saw no film or change in my tongue's appearance.

I have been for the last several months over the incision were it was drained forming a pus filled pimple that will grow then pop on it owns and the cycle repeats itself. Now another pus filled pimple has grown close to it as dose the exact same thing.
