Can you tell me reasons why i have toothache when i lay down?

Pressure: When you lay down the blood vessels get dilated with a little more blood. This can place more pressure on the nerves. When you are sitting upright the blood has to work a little harder going uphill to get to the jaw. When lying down the blood flow is a little greater (no gravity to fight) and blood vessels can dilate a little bit.

Blood circulation: When one lies down, the blood circulates to the neck and the head area. That's why toothache is more likely to get worse during night when you lie down.

Blood flow, but: Changes in blood flow to an infected area. Key is see your dentist to determine problem with the tooth.
