Why Do My Teeth Hurt at Night? Understanding the Causes and Solutions

There are several possible reasons why your teeth may hurt at night, including tooth decay, grinding or clenching, gum disease, sinus infections, or nerve damage. It’s important to see a dentist to determine the exact cause and receive appropriate treatment.

Possible Causes of Nighttime Tooth Pain

As someone who has experienced nighttime tooth pain, I know how frustrating it can be to try and get a good night’s rest.

There are several possible causes of nighttime tooth pain, and understanding them can help you find relief.


One possible cause of nighttime tooth pain is bruxism, which is the grinding or clenching of teeth.

This can put pressure on the teeth and cause pain, especially at night when you may not be aware that you are doing it.

Bruxism can also lead to other dental problems, such as worn-down teeth and TMJ disorder.

Gum Disease

Gum disease, also known as periodontal disease, is an infection of the gums that can cause tooth pain.

This is because the infection can spread to the roots of the teeth, causing them to become sensitive and painful. Gum disease can also cause other symptoms, such as bleeding gums and bad breath.

Tooth Decay

Tooth decay, also known as cavities, is another possible cause of nighttime tooth pain.

This is because the decay can expose the nerves in the teeth, causing them to become sensitive and painful. In severe cases, tooth decay can also lead to infection and abscesses.

Sinus Infection

A sinus infection can also cause tooth pain, especially in the upper teeth.

This is because the sinuses are located close to the roots of the upper teeth, and the pressure from the infection can cause pain in the teeth.

Other symptoms of a sinus infection include congestion, headache, and facial pain.

Overall, there are several possible causes of nighttime tooth pain, and it is important to see a dentist if you are experiencing persistent pain.

They can help diagnose the cause of the pain and recommend the appropriate treatment.

Prevention and Treatment

Good Oral Hygiene Habits

I always make sure to brush my teeth twice a day, in the morning and before bed. Brushing assists eliminate plaque and food particles that with canning cause tooth rot and gum sickness.

I also floss once a day to remove any food particles that may be stuck between my teeth. In addition to brushing and flossing, I try to limit my intake of sugary and acidic foods and drinks.

These can erode tooth enamel and cause sensitivity and decay.

I also make sure to drink plenty of water throughout the day to help flush away any bacteria and food particles that may be lingering in my mouth.


If you grind your teeth at night, a mouth guard may be recommended by your dentist. Mouth guards can help protect your teeth from damage caused by grinding and clenching. They can also help relieve any pain or discomfort associated with bruxism.


Over-the-counter pain relievers such as ibuprofen or acetaminophen can help relieve minor tooth pain. Numbing pastes or gels containing benzocaine can also be applied to the affected area to help relieve pain.

Professional Dental Care

Regular dental checkups and cleanings can help prevent tooth pain and identify any potential issues before they become more serious.

Your dentist may also recommend treatments such as fillings, root canals, or extractions to address any underlying issues causing tooth pain.

In addition to regular dental visits, professional teeth cleaning can help remove any plaque or tartar buildup that may be contributing to tooth pain.

Your dentist may also recommend fluoride treatments to help strengthen your tooth enamel and prevent decay.

Overall, maintaining good oral hygiene habits, using mouthguards if necessary, taking pain relievers or numbing agents when needed, and seeking professional dental care can all help prevent and treat tooth pain at night.
