why do teeth hurt when sick

Feeling under the weather and suddenly your teeth are aching? It's more common than you might think. While a toothache unrelated to illness is certainly possible, several factors can link sickness and tooth pain. This comprehensive guide explores the reasons behind this uncomfortable connection.

What Causes Tooth Pain When Sick?

The relationship between illness and tooth pain isn't always direct. It's often indirect, stemming from the body's overall inflammatory response to infection or the impact of certain illnesses on oral health. Let's dive into some key reasons:

1. Sinus Infection:

This is a frequent culprit. Sinus infections, or sinusitis, cause inflammation and pressure buildup in the sinuses located above and behind your teeth. This pressure can radiate into your teeth, causing pain, especially in the upper molars. The pain might feel like a dull ache or a sharp throbbing.

2. Weakened Immune System:

When you're sick, your immune system is working overtime to fight off infection. This weakened state can make you more susceptible to oral infections like gum disease or tooth abscesses, which can manifest as tooth pain. Existing dental problems become more aggravated under compromised immune function.

3. Dehydration:

Many illnesses cause dehydration, and a dry mouth can significantly contribute to tooth pain. Saliva plays a crucial role in protecting your teeth by neutralizing acids and washing away food particles. When you're dehydrated, saliva production decreases, making your teeth more vulnerable to decay and sensitivity.

4. Grinding or Clenching Teeth (Bruxism):

Stress and illness often go hand-in-hand. Increased stress levels can lead to bruxism – the unconscious grinding or clenching of teeth, especially during sleep. This puts significant pressure on your teeth and jaw, causing pain and potentially exacerbating existing dental problems. The pain associated with bruxism can be intensified when you are already unwell due to general discomfort.

5. Medication Side Effects:

Some medications taken to treat illnesses can have side effects that impact oral health. Certain medications can cause dry mouth, increasing sensitivity and the risk of infections. Others might directly affect the teeth or gums. Always check the medication's side effects list and consult your doctor or pharmacist if you have concerns about your oral health.

Is Tooth Pain a Symptom of a Specific Illness?

While tooth pain isn't a direct symptom of most illnesses, it can be associated with certain conditions, primarily those involving infection and inflammation:

  • Viral Infections: Flu or common colds can weaken your immune system, making you more prone to oral infections and related pain.
  • Bacterial Infections: Bacterial infections, like strep throat, can indirectly contribute to tooth pain through inflammation or general discomfort.

It's important to note that tooth pain associated with sickness is often not the primary symptom. The underlying illness usually manifests more prominently.

When to See a Dentist or Doctor:

If you experience tooth pain while sick, it's vital to determine the cause. Seek professional help if:

  • The pain is severe or persistent.
  • You notice swelling or inflammation in your gums or face.
  • You have a fever or other signs of infection.
  • The pain doesn't subside after a few days.

Your dentist can assess your oral health and determine if a dental issue is the primary cause of your discomfort. Your doctor can diagnose any underlying illness contributing to the pain.

Conclusion:

Tooth pain when sick is often a secondary issue, stemming from the body's response to illness or the impact on oral health. Understanding the possible connections – from sinus infections to dehydration and medication side effects – allows for appropriate management and timely professional intervention when necessary. Always prioritize comprehensive care by addressing both the underlying illness and any resulting dental complications.
