Toothache is unpleasant, no matter what level you’re experiencing it at. However, it is the suddenness of the pain that is the absolute worst, especially when it starts out of nowhere.

Although the sensation itself is hard to describe, the intense wave of discomfort slowly spreading from one tooth to the next can make it extremely difficult to eat, sleep, talk, or even focus on menial tasks.

If you have ever felt like all your teeth suddenly started to hurt at the same time, it could be due to an underlying condition. To find out what causes it, carry on reading this blog.

Why Do All My Teeth Suddenly Hurt?

If your teeth suddenly start to hurt, it could be because of the following reasons:

Receding Gums

Gums protect your teeth and keep them safe in one place. But if they pull away, it could expose the tooth nerves and roots, resulting in dental pain.

Tooth Decay

Cavities are known to be excruciating, with the bacteria gradually chipping away at the tooth’s surface until reaching its core. Once the bacteria get to the tooth’s center, throbbing pain is soon to follow.

Weak Enamel

The enamel is what keeps your teeth well-protected, especially the dentin and pulp inside of them. Since it is the strong, sturdy outer layer of the tooth, when it wears away, it makes your teeth appear yellow and causes a ton of pain along with sensitivity.


Not all habits are healthy. Clenching and grinding your jaw is especially damaging since it weakens the teeth from their roots. Thus, once the teeth are loose enough, it can give way to a lot of pain every time you open your mouth to eat, speak, or drink.

TMJ Syndrome

The temporomandibular joint connects your lower jaw to the skull, but it can cause numerous jaw-related pain when damaged. In some cases, the pain can also travel to your teeth, ear, and neck, leading to sheer discomfort.

Oral Hypersensitivity

Sometimes the pain you feel is merely due to sensitive teeth. If all your teeth suddenly hurt after you drink something really cold or eat something extremely hot, it may as well be teeth sensitivity acting up.


Malocclusion occurs when your teeth are misaligned or too crowded due to insufficient space in the mouth. This can cause pressure and pain to erupt in your mouth, affecting all the teeth at once.


When your sinuses get inflamed, it results in a condition known as sinusitis. Given how sinuses are tiny cavities filled with air, every time pressure is applied, it can give way to immense tooth pain.

Cracked or Fractured Dental Crown

Not many people realize this, but the instant your dental crown falls off or suffers from a deep crack, it is considered a dental emergency. The purpose of a crown is to protect and cover a damaged tooth. Therefore, when it gets damaged, intense pain can radiate through your mouth and affect all teeth.

Long Story Short

For all your teeth to suddenly hurt is not normal. It could indicate that something is seriously wrong with your oral health and needs to be treated immediately. In some cases, it might be an emergency, whereas in others, it could be a result of poor oral hygiene.

No matter what the reason may be, let your dentist know. Only a dental expert can minimize the pain and help relieve it long-term. For more information, you can reach out to Signature Smiles at any of the following locations:
