< Why Does My Teeth Hurt After Crying? >

Experiencing tooth pain after crying is a common issue that many people encounter. This discomfort can be mild or severe, and it often leaves individuals wondering about the cause behind it. There are a few factors that contribute to this phenomenon, including changes in blood flow, sinus pressure, and teeth clenching during emotional moments.

Changes in Blood Flow:

When we cry, our body undergoes several physiological changes. One of these changes is an increase in blood flow to the face and head. This can cause a temporary rush of blood to the teeth and gums, leading to a sensation of tooth pain.

Sinus Pressure:

Another factor that can cause tooth pain after crying is sinus pressure. Our sinuses are located near the upper jaw and cheekbones. When we cry, the tear ducts can become blocked, resulting in increased pressure in the sinuses. This pressure can radiate to the teeth, causing discomfort.

Teeth Clenching:

During crying episodes, some individuals may unknowingly clench their teeth or jaw. This can happen due to stress or emotional tension. Teeth clenching can strain the jaw muscles and put pressure on the teeth, leading to pain or sensitivity.


Crying can often lead to dehydration as tears are released from the body. Dehydration can cause dry mouth and a decrease in saliva production. Saliva is crucial for maintaining oral health, as it helps to protect the teeth and gums. When saliva levels are low, the teeth can become more susceptible to pain and sensitivity.


In some cases, individuals who grind their teeth at night, a condition called bruxism, may experience increased tooth pain after crying. The extra strain on the teeth and jaw muscles during crying can exacerbate the effects of bruxism, leading to heightened discomfort.

Other Contributing Factors:

Aside from the factors mentioned above, there are a few additional elements that can contribute to tooth pain after crying.

  • Sinus infections or allergies can cause inflammation and pain in the sinuses, which may radiate to the teeth.
  • Inflammation of the temporomandibular joint (TMJ) due to stress or tension can result in pain in the jaw and teeth.
  • Underlying dental issues such as cavities, gum disease, or cracked teeth can also be a source of tooth pain.

Solutions and Prevention:

To alleviate tooth pain after crying, it is essential to address the underlying causes. Here are some tips:

  1. Practice stress-reducing techniques like deep breathing or meditation to reduce teeth clenching during emotional moments.
  2. Stay hydrated by drinking plenty of water to prevent dehydration-related tooth sensitivity.
  3. Use a warm compress or saline rinse to relieve sinus pressure and decrease tooth pain.
  4. If you suspect bruxism, consult a dentist for a custom mouthguard to protect your teeth while you sleep.
  5. Maintain good oral hygiene and visit a dentist regularly to identify and treat any underlying dental issues.

In conclusion, tooth pain after crying can be attributed to various factors such as changes in blood flow, sinus pressure, teeth clenching, dehydration, and bruxism. Understanding these causes and implementing preventive measures can help alleviate discomfort and ensure optimal oral health.
