BrushPeople wonder why a dead tooth is painful, yet the nerve endings are dead. The reason is, when you have a dead tooth, pus builds up in your pulp, thus causing pain.
Key takeaways:
– A dead tooth occurs when a tooth is severely decayed or there has been trauma that cuts off blood supply.
– Symptoms are swelling, headaches, bad taste and odour and discolouration.
– For treatment, your dentist will extract the tooth or carry out root canal therapy.
Keep your mouth clean and see the dentist regularly for checkups.
