Why Do My Teeth Hurt When I Wake Up?

Why Do My Teeth Hurt When I Wake Up?

There are three main reasons why your teeth may hurt when you wake up.

First, your teeth may hurt because of the pressure you put on them while sleeping. This can be due to snoring or teeth grinding.

Second, your pain may be caused by dental nerve sensitivity. This is when the nerves in your teeth become irritated and inflamed.

Third, if the pain is mild and sudden, it could be due to dry mouth or other non-serious conditions like an infection or tooth decay. This article will look at the possible causes for your teeth hurting when you wake up.

Sinus Infection

A sinus infection is a bacterial or viral infection that affects the sinuses. It can also cause pain in the teeth and face, fever, headache, and a blocked nose. Sinus infections can result from a cold or flu-like illness, allergies, nasal polyps, chronic sinusitis, and other conditions.

When the sinuses are infected with bacteria or viruses, they become inflamed and produce excess mucous. This excess mucous builds up in your nose and blocks your nose passages, causing your breathing to be difficult, forcing you to breathe through your mouth instead of your nose, which dries out the inside of your mouth, causing pain in your teeth on waking up.

Night Grinding or Clenching

Certain movements and activities can cause tooth pain in the morning. Night grinding or clenching is the most common reason for this.

When you grind or clench our teeth, it causes severe wear and tear on the top and bottom of the molars. The enamel breaks down and eventually wears away. This causes sensitivity in your teeth and pain when you wake up.

Gum Disease

Gum disease is a long-term oral health problem affecting the tissues and bones surrounding and supporting the teeth. People with gum disease often experience pain when they eat or brush their teeth.

The most common symptom of gum disease is bleeding gums. If you notice blood in your toothbrush after you brush, or if your gums bleed when you brush your teeth, it could be a sign of gum disease. Some people with gum problems also experience bad breath or loose teeth.


Many women experience this discomfort during pregnancy. The hormones released in pregnancy cause your teeth to become more sensitive.

A regular toothbrush will not do the trick, so you should use a very gentle toothpaste and an electric toothbrush with a rotating head. To avoid sensitivity, use cooler water than usual when brushing your teeth.

Sleep Position

It is not uncommon for people to wake up with a throbbing toothache after sleeping in an awkward position. The first thing you should do upon waking up is brush your teeth and rinse out your mouth.

You should also consult a dentist if you are experiencing pain that doesn’t go away after a day or two because sometimes, the problem might be more serious.

Nerve Damage

Nerve damage can cause your teeth to hurt when you wake up because it’s a symptom of an injury to a nerve that controls sensation in your teeth.

When you have this condition called paresthesia, it means that some type of injury has occurred to one of these nerves that carries sensory information about your teeth or mouth.

Overuse of Mouthwash

Overuse of mouthwash can cause your teeth to hurt when you wake up due to tooth erosion. This tooth erosion occurs because the chlorine in mouthwash destroys tooth enamel which is crucial for healthy teeth.

To prevent this from happening, rinse with water after using the mouthwash instead of brushing your teeth with it.


You may feel like you have a pounding headache when you wake up or that your teeth are throbbing. This feeling may be caused by dehydration.

Although it can happen to anyone, people with higher-than-normal blood pressure are more at risk of dehydration because the kidneys cannot eliminate enough fluids. If you do not drink enough water, your body will turn to other sources for hydration, such as tissue in your mouth and stomach lining.

Acidic Foods

Acidic foods can cause your teeth to hurt when you wake up because of the acidity level. When you eat acidic foods such as orange juice, wine, and many fruits and vegetables, the high acid level can stay in your mouth overnight, which causes tooth sensitivity or pain.

You Frequently Vomit

Frequent vomiting can cause your teeth to hurt when you wake up. That’s because the acid in your stomach is regurgitated and lands on your teeth. This causes changes in the pH of your mouth, which causes pain.

Many people think that it’s just their morning breath or dry mouth, but it could be something more severe like GERD, heartburn, or chronic vomiting. You should consult a doctor if you have any of those symptoms and those from frequent vomiting.

Tips to Reduce Tooth Pain in the Morning

While tooth pain in the morning may make you feel like you are the only one, many others suffer from it. You don’t have to live with this feeling anymore!

Here are some tips to reduce tooth pain in the morning:

  • Do not brush your teeth right before you go to bed.
  • Maintain healthy oral habits and stay away from sugary drinks and candies.
  • Avoid drinking excessive alcohol or coffee before bedtime.
  • Make sure you get enough sleep and eat a balanced diet (which includes calcium).

Saltwater Rinse

The introduction of saltwater into the mouth is not a new idea. It is used in many cultures, particularly in communities that do not have access to good dental care. Saltwater can help to kill off any bacteria and maintain good oral health.


Many people will wake up and brush their teeth without even thinking about the pain in their gums. Ignoring the pain for too long can lead to more severe problems like tooth decay and gum disease, leading to the loss of teeth.

You should never ignore this problem or delay possible treatment. You should always try to take care of your teeth as soon as possible because they are essential, and loss of any teeth can be painful and permanent.
