Why do my teeth hurt after chewing

Reasons for Tooth Pain After Chewing

There are several potential reasons why your teeth might hurt after chewing:

  • Tooth Decay (Cavities): When decay penetrates the enamel and reaches the dentin, chewing can cause pain.
  • Gum Disease: Inflammation and infection of the gums can lead to pain while chewing.
  • Cracked or Fractured Teeth: Even small cracks can cause significant pain when pressure is applied.
  • Tooth Sensitivity: Exposure of the dentin or receding gums can make teeth sensitive to pressure.
  • Bruxism (Teeth Grinding): Grinding can wear down teeth and cause pain during chewing.
  • Dental Work: Recent fillings, crowns, or other dental work can cause temporary sensitivity and pain.
  • Infections: Abscesses or other infections in the teeth or gums can cause pain.
  • Misaligned Bite: An uneven bite can put extra pressure on certain teeth, causing discomfort.
  • Sinus Issues: Sinus infections or pressure can cause referred pain in the upper teeth.

It's best to consult with a dentist to determine the exact cause of your pain and get appropriate treatment.

Does Pain When Chewing Mean a Root Canal?

Pain when chewing does not necessarily mean you need a root canal, but it can be one of the signs that indicate a more serious problem that might require this treatment. Here are some signs and conditions that might necessitate a root canal:

  • Severe Tooth Decay: If decay has reached the pulp (the innermost part of the tooth containing nerves and blood vessels), a root canal might be needed.
  • Infection or Abscess: An infection in the tooth's pulp can cause significant pain and typically requires a root canal to remove the infected tissue.
  • Cracked or Fractured Tooth: If a crack extends into the pulp, it can cause pain and require a root canal.
  • Persistent Pain: Ongoing pain, especially when chewing or applying pressure, can be a sign that the pulp is damaged or infected.
  • Prolonged Sensitivity: Sensitivity to hot or cold that lingers after the stimulus is removed might indicate pulp damage.
  • Swelling and Tenderness: Swelling around the tooth or in the face can be a sign of infection requiring a root canal.
  • Discoloration: A tooth that has become discolored due to damage or infection might need a root canal.

However, pain when chewing can also be caused by less severe issues, such as minor tooth decay, gum disease, or a recent dental procedure. It's important to consult with a dentist to determine the exact cause of the pain and whether a root canal or another treatment is necessary.

A dentist can often pull an infected tooth on the same day, but it depends on several factors:

  • Severity of Infection: If the infection is severe and the surrounding tissue is significantly swollen or if there's an abscess, the dentist might need to prescribe antibiotics first to reduce the infection and swelling before performing the extraction.
  • Patient's Health: If the patient has certain health conditions or is taking specific medications, the dentist might need to take additional precautions before proceeding with the extraction.
  • Complexity of Extraction: If the tooth extraction is expected to be complex (e.g., impacted wisdom teeth), the dentist might refer the patient to an oral surgeon, which could delay the extraction.
  • Availability of Equipment and Staff: The dentist's office must have the necessary equipment and staff available to perform the extraction safely.

It's important to consult with your dentist, who will evaluate your specific situation and determine the best course of action. If an immediate extraction isn't possible, the dentist will typically provide pain relief and antibiotics to manage the infection until the tooth can be safely removed.

Will Pulling an Infected Tooth Stop the Infection?

Pulling an infected tooth can help stop the infection, but it may not completely eliminate it. Here's what generally happens:

  • Removal of the Source: Extracting the infected tooth removes the primary source of the infection, which can significantly reduce the infection and prevent it from spreading.
  • Drainage of Abscess: If there's an abscess associated with the infection, pulling the tooth can help drain it, which can also help reduce the infection.
  • Antibiotics: Dentists often prescribe antibiotics before or after the extraction to ensure that any remaining infection is fully treated. This is especially important if the infection has spread beyond the tooth.
  • Post-Extraction Care: Proper post-extraction care is crucial. This includes keeping the extraction site clean, following the dentist's instructions, and taking all prescribed medications.

While extraction is a key step in addressing an infected tooth, follow-up care and monitoring are essential to ensure the infection does not persist or spread. Always follow your dentist's advice and complete any prescribed course of antibiotics. If you notice any signs of continued infection, such as persistent pain, swelling, or fever, contact your dentist immediately.
