Small wounds could be very dangerous.
Please consult a doctor.
By the way I like to share this with you:
I had bleeding gum decease for many years.
I went to this dentist (he is very unconventional) and he ask me to apply hydrogen peroxide (3% solution) using tiny tooth brushes.
I was cured within a week.
Now I use HP as mouthwash (diluted) when I have sore throat and apply to small wounds too.
HP is a cheap over the counter medicine.
