If your teeth hurt suddenly, some of the most common reasons are:
- Tooth sensitivity (pain is triggered by hot or cold because of weak or worn tooth enamel)
- Gum disease (might have already changed how you bite or resulted in loose teeth)
- Dental cavities or abscess (can cause sudden severe pain out of nowhere or you felt it when you chewed something)
- Tooth grinding (also called bruxism, this wears down tooth enamel and makes your teeth sensitive or completely damaged)
- Temporomandibular joint syndrome (TMJ, a musculoskeletal syndrome where pain can also radiate to the teeth)
- Crowded and misaligned teeth (this can cause pressure and pain)
- Sinusitis (sinuses are inflamed and the pain might radiate to the teeth)
Notice there are several potential causes. It’s important to visit a dentist as soon as possible so you can be sure of the reason. Also, this is a way for you to receive on-the-spot treatment so that you won’t feel the pain anymore and you will immediately gain peace of mind and comfort (so you can eat normally again without worrying about the pain).
