A few thoughts..: You may be grinding your teeth at night, causing stress on the support structures of the tooth. In addition, the tooth may have an abscess, and when you lie down, the blood pressure rises in your head, causing the tooth to throb as your heart beats. Either way see a dentist for a proper diagnosis and treatment.
