Why Does It Hurt When I Bite Down? Uncovering the Causes of Tooth and Jaw Pain
Experiencing pain when you bite down can be incredibly disruptive, making even simple tasks like eating uncomfortable. This pain can stem from various sources, ranging from minor irritations to serious dental issues. Understanding the potential causes is the first step towards finding relief. This comprehensive guide explores the common reasons behind biting pain and offers insights into diagnosis and treatment.
What are the common causes of pain when biting down?
Pain when biting down, also known as occlusal pain, can originate from several sources within your mouth and jaw. Let's examine some of the most frequent culprits:
-
Tooth Decay (Cavities): Decay weakens tooth enamel, leading to sensitivity and pain, particularly when pressure is applied during biting. The deeper the decay, the more intense the pain.
-
Cracked Tooth: A crack, even a microscopic one, can expose the sensitive inner layers of your tooth, resulting in sharp pain upon biting. This pain can be intermittent or constant, depending on the severity and location of the crack.
-
Abscessed Tooth: A tooth abscess is a painful infection at the root of a tooth. The pressure from the infection can cause intense pain that worsens when biting down. This is a serious condition requiring immediate dental attention.
-
Gum Disease (Gingivitis or Periodontitis): Inflammed gums can be sensitive to pressure, causing discomfort when biting. Advanced gum disease (periodontitis) can also damage the supporting structures of your teeth, further exacerbating the pain.
-
Temporomandibular Joint (TMJ) Disorders: The TMJ connects your jaw to your skull. Disorders of this joint, such as TMJ syndrome, can cause pain in the jaw, ear, and face, often worsened by biting or chewing.
-
Bruxism (Teeth Grinding): Habitual teeth grinding, often done unconsciously at night, can wear down tooth enamel and cause jaw muscle pain. This pain is typically felt when biting down, especially after a period of grinding.
-
Dental Injuries: A previous injury to a tooth or jaw can lead to long-term pain that's aggravated by biting.
-
Sinus Infection: While less common, a sinus infection can sometimes cause referred pain that mimics toothache, particularly in the upper teeth. The pain might intensify when biting down.
-
Wisdom Teeth: Impacted or partially erupted wisdom teeth can cause pain and inflammation, affecting your ability to bite comfortably.
What are some less common causes of pain when biting down?
While the causes listed above are the most frequent, some less common reasons can also contribute to pain:
-
Osteoarthritis or Rheumatoid Arthritis of the Jaw: These conditions can affect the TMJ, causing pain and stiffness.
-
Dental Malocclusion (Misalignment): Improper bite alignment can put uneven pressure on teeth, causing pain when biting.
-
Dental Implant Complications: Problems with dental implants, such as infection or implant failure, can also lead to pain.
When should I see a dentist about pain when biting down?
If you experience persistent or severe pain when biting down, you should schedule an appointment with your dentist immediately. Don't delay seeking professional help, as many of the underlying causes require prompt treatment to prevent further complications. Pain that is accompanied by swelling, fever, or other systemic symptoms warrants immediate attention.
How is pain when biting down diagnosed?
Your dentist will conduct a thorough oral examination, including checking for cavities, cracks, abscesses, gum disease, and any signs of TMJ disorders. They may take X-rays to identify underlying problems, such as impacted teeth or bone loss.
What are the treatment options for pain when biting down?
Treatment depends entirely on the underlying cause. Options can range from simple fillings and cleanings to more complex procedures like root canals, crowns, extractions, or TMJ therapy. In some cases, medication may be necessary to manage pain and inflammation.

Regular dental checkups are crucial for early detection and prevention of problems that can cause pain when biting down.
