I have severe periodontal disease which was diagnosed in 2007, but only just treated (terrible dentist originally) I am only 32 - it's almost unheard of at my age. I was referred to a specialist when some of my teeth became loose.
Initially I worried that CD had had an impact on it. Now that I know a lot more about the disease I know that that's not the case. Do you smoke at all by the way or have you recently given up?
You teeth are likely to be bleeding more since starting CD because saliva helps to flush away the germs that can cause gum disease. As you are not eating you are not going to be salivating as much. That's probably why that's happened. Stopped smoking makes your gums bleed a LOT more! That's because smoking leads to inadequate blood supply and when you stop, as it returns to normal, your gums bleed.
You could try chewing gum, although on CD that's not recommended because it can stimulate the appetite.
Seeing that you posted 2 days ago, how did you get on at the dentist? Everyone has gum disease to some extent - some more than others. Bleeding gums is a symptom and once you are taught how to effectively and properly maintain dental hygiene you can usually halt it. If you're anything like me you maybe think you already know how to brush your teeth?
I used to brush for 4 minutes with my electric tooth brush and think I was doing a good job. Now I do that, as well as floss, clean the teeth that are proven to be neglected with another brush and interdentally brush. My teeth which had bled for years stopped bleeding within 3 days of this regime. Having had surgery a few weeks ago I am confident that I will keep most if not all of my teeth now
Sorry for the essay, but it's my new specialist subject lol
