Why do my teeth randomly hurt
Teeth that hurt intermittently may have decay, a cracked tooth, irritated pulp, gum disease, exposed dentin, bite overload, or referred pain.
The short answer
Teeth that hurt intermittently may have decay, a cracked tooth, irritated pulp, gum disease, exposed dentin, bite overload, or referred pain. Tooth pain can start when pressure, temperature, sweet foods, or inflammation activates nerves in the pulp or tissues around the root. Pain that stops quickly differs from pain that lingers, occurs spontaneously, or worsens when biting.
What is the direct answer?
What does this question mean?
Record which tooth seems involved, what triggers the pain, how long it lasts, and whether it wakes you. Avoid extreme temperatures on that side, keep the area clean, and use only pain medicine suitable for you as directed on its label.
What can you do next?
Book an examination for repeated, spontaneous, lingering, or bite-related pain. Urgent care is needed with swelling, fever, pus, difficulty opening the mouth, or trouble swallowing or breathing.
When should you seek dental care?
Does the pain point to the pulp, a crack, the gum, or the bite? Ask whether testing with cold, tapping, bite pressure, and X-rays can identify the source.
