Yes: Acute pulpitis is an inflammation of the nerve or the pulp inside your tooth if it's just mildly irritated throughout the day when you're active and you're concentrating on everyday activities you may not notice the pain so much but at night when you relax and you're not thinking about everyday decisions minor aches and pains are more noticeable to the body.

Vascular engorgement: Inflammation causes increased blood flow in the vessels of the pulp. When you lie down, this engorge ment can increase. The pulp is limited in space and confined within the hard tooth structure, so the increased volume of blood causes pressure and pain.

True. Your blood pressure will increase to your jaw(teeth) when you lay down. Therefore, as Dr Grossman explained, this pressure affects the blood vessels increasing pain.

Nerve: The nerve is dying and when you lay down the blood pressure change causes the tooth to hurt more. See the base endodontist.
