This morning, I woke up and my teeth were covered in blood. Parts of the blood were dry, some parts weren't. This is common for me, I am not quite sure why. This morning, however was different. I sat on the toilet (before brushing my teeth) and felt my mouth fill with blood. I spat it out and there was quite an excessive amount and it was bright red, there was even tiny clots. I spat a few more times and still, excessive bleeding. I then started to brush my teeth and the bleeding stopped. There were no blood on my tooth brush, so I am worried that it didn't come from my gums. Surely if it had have come from my gums, brushing would have irritated it further. I am confused. I am not sure what is happening. Do I call the doctors or my dentist? Should I leave it? If anyone can help somehow, I'll be forever grateful. Thanks.
