Toothache or Sinus Infection? How to Tell the Difference

Many people feel pain in their teeth or face and wonder, “Is this a toothache or sinus infection?” Both can cause discomfort, but they are not the same. Toothaches often come from dental problems, while sinus infections affect the spaces near your nose. Knowing the difference is important for the right treatment. In this blog, you will learn how to tell if it’s a toothache or sinus infection, the main symptoms, causes, and how to get relief.

What Is a Toothache?

A toothache is pain in or around a tooth. Usually, it happens when the nerve inside the tooth gets irritated. Often, this pain is sharp or throbbing. Sometimes, it gets worse when you eat or drink something hot or cold. Toothaches can make it hard to chew or even talk. If left untreated, the pain may spread to your jaw or ear.

What Is a Sinus Infection?

A sinus infection, also called sinusitis, happens when the spaces near your nose get swollen or infected. These spaces are called sinuses. When they fill with fluid, germs can grow and cause pain. Sinus infections can make your face feel heavy or sore. Sometimes, the pain spreads to your upper teeth, which can be confusing. According to the CDC, sinus infections are common and often follow a cold.

Key Symptoms: Toothache vs. Sinus Infection

It can be hard to know if your pain is from a toothache or sinus infection. However, some signs can help you decide. Here are the main symptoms for each:

  • Toothache Symptoms:
  • Pain in one tooth or area
  • Sharp, throbbing, or constant pain
  • Pain when biting or chewing
  • Sensitivity to hot or cold foods
  • Swelling around the tooth or gum
  • Bad taste in the mouth
  • Sinus Infection Symptoms:
  • Pressure or pain in the cheeks, forehead, or behind the eyes
  • Stuffy or runny nose
  • Pain in several upper teeth at once
  • Worse pain when bending over
  • Fever or tiredness
  • Thick yellow or green mucus
  • Sometimes, sinus infection tooth pain relief comes when you treat the sinus problem, not the teeth.

    Causes and Risk Factors

    Understanding the causes can help you know if you have tooth pain vs sinus pain. Here are the main causes and risk factors:

  • Toothache Causes:
  • Cavities (holes in teeth)
  • Gum disease
  • Cracked or broken teeth
  • Dental abscess (infection)
  • Teeth grinding
  • Sinus Infection Causes:
  • Colds or flu
  • Allergies
  • Nasal polyps (small growths in the nose)
  • Deviated septum (crooked nose wall)
  • Weakened immune system
  • For both conditions, smoking and poor hygiene can increase your risk. However, sinus infections often follow a cold or allergy attack.

    How to Diagnose: When to See a Dentist or Doctor

    Sometimes, it is hard to know if you have a toothache or sinus infection. If your pain lasts more than a few days, you should see a dentist or doctor. Here are signs you need help:

  • Severe or spreading pain
  • Swelling in your face or jaw
  • Fever that does not go away
  • Pus or bad taste in your mouth
  • Pain that does not improve with home care
  • Often, dentists use X-rays to check your teeth. Doctors may look at your nose or order scans to see your sinuses. Early diagnosis helps you get the right treatment.

    Treatment Options

    Treatment depends on the cause of your pain. For toothaches, dentists may:

  • Fill cavities
  • Clean infected gums
  • Prescribe antibiotics for infections
  • Recommend pain relievers
  • For sinus infections, doctors may suggest:

  • Decongestants or nasal sprays
  • Saline rinses
  • Antibiotics if bacteria are present
  • Pain relievers
  • Sometimes, sinus infection tooth pain relief comes after treating the sinus problem. If you are unsure, always ask a professional.

    Prevention Tips

    While you cannot prevent all toothaches or sinus infections, these tips can help lower your risk:

  • Brush and floss your teeth daily
  • Visit your dentist twice a year
  • Avoid smoking
  • Wash your hands often to prevent colds
  • Manage allergies with your doctor’s help
  • Drink plenty of water
  • Good habits can keep your teeth and sinuses healthy.
