Yesterday while I was brushing my teeth I felt an urge to scratch a part of my gums. So I did. And it started to bleed, but it's still so ichy, so when I sratch it, it bleeds more. Do you think it's a alergic reaction?? If you don't think so, tell me what you think it is.

I would think if it were an allergic reaction ALL of your gums would be itchy. Have you recently started to do a better job with your brushing and flossing? Sometimes you can get an itchy feeling when your gums start to get healthy. Instead of using the toothbrush to scratch them just use your fingertip and gently massage the area. You can also rinse with some warm water and salt.
