Hello, I can understand your concern. Not brushing teeth can cause decay in teeth along with deteriorating health of gums by plaque and calculus (tartar) accumulation. As your sleep was disturbed, it is a typical symptom of development of acute irreversible pulpitis due to decay of a particular tooth that pains. It might be present in both upper and lower tooth or one tooth may cause referred pain in the other arch. When we sleep, blood supply in the head region increases causing shooting pain in the teeth that are affected by decay and pulpitis. I advise you to visit a dentist for clinical evaluation of your oral cavity. You may need to go for root canal treatment of the decayed tooth or extraction depending on the extent of the decay. You should also go for ultrasonic scaling at the dentist s which is mechanical cleaning of the plaque and calculus accumulated over the gum margins. It will give you relief in bleeding gums. In addition, you should start toothbrushing twice a day, use of mouthwash, floss and gum paint. I hope this information helps you. Thank you for choosing HealthcareMagic. I wish you feel better soon. Best, Dr. Viraj Shah
