Q. I had an infection in my impacted wisdom tooth lower left side. I have been give antibiotics for 7 days which I finished 5 days ago. When I rub my gum with my finger it still has the same unpleasant smell as before albeit milder. I was told to use Corsodyl on it which I am doing. I am almost 60 years old, there is no pain, but……….before taking the antibiotics I developed a swelling under my arm, the doctor said it was my gland but didn’t seem too worried and said “keep an eye on it”. Whilst taking the antibiotics the swelling reduced in size to about a third, but now I think it is getting a little larger although hard to tell. Could this swelling be connected to the tooth? The swelling is on the opposite side.
