I have experience with it.
of course, my dentist prescribed a bleeding gums treatment for me.
her prescribed a mouthwash containing chlorhexidine, and I find out that this is one of the most common treatments.
he told me that we will try with this, but he also mentioned me that sometimes he prescribes some other antibiotics, that can be inserted below the gum line.
but when he told me this, he also mentioned to me that this type of antibiotic is used in concert with a deeper cleaning called scaling and planning and this is something that he recommends in more difficult cases.
so, visit your dentist and let him determine the treatment for you.
