Back teeth pain is one of the most common dental complaints people experience at some point in their lives.
If your back teeth hurt, it can make everyday activities like eating, drinking, or even talking uncomfortable.
Many people ignore pain in their back teeth, assuming it will go away on its own. In reality, back teeth pain often signals an underlying issue that needs attention.
Because molars do most of the chewing work, they are more prone to damage, decay, and pressure related problems.
Understanding why your back teeth hurt is the first step toward finding lasting relief and protecting your oral health.
This guide explains the most common causes of back teeth pain, how to manage discomfort at home, and when it is important to visit a dental professional.
Early dental guidance can prevent minor discomfort from turning into serious dental problems.
Why Do My Back Teeth Hurt?
When back teeth hurt, the pain can come from several different sources.
The molars are larger teeth with deep grooves, which makes them more likely to trap food particles and bacteria.
They also absorb most of the pressure when chewing, increasing the risk of wear and tear.
Pain in the back teeth may be sharp, dull, throbbing, or sensitive to hot and cold foods.
Sometimes the discomfort develops slowly, while in other cases it appears suddenly.
Identifying the exact reason behind the pain helps determine the right treatment approach.
Common Causes of Back Teeth Pain
Tooth Decay or Cavities in Back Teeth
Cavities are one of the leading reasons why back teeth hurt.
Molars have pits and grooves that make them harder to clean properly.
When plaque builds up, bacteria produce acids that weaken the tooth enamel.
Over time, this leads to decay and painful cavities.
If left untreated, cavities can reach deeper layers of the tooth and cause intense pain.
Early signs include sensitivity to sweets, cold drinks, or pressure while chewing.
Wisdom Teeth Pain and Eruption Problems
Wisdom teeth often cause discomfort when they begin to emerge.
These teeth usually appear in the late teens or early twenties.
If there is not enough space in the jaw, wisdom teeth may grow at an angle or become trapped under the gums.
This can cause swelling, pain, and infection around the back teeth.
Wisdom tooth pain may also radiate to the jaw or ear.
Gum Infection or Gum Disease
Gum disease is another common cause of back teeth pain.
When bacteria accumulate along the gum line, inflammation can develop.
Early gum disease may cause redness, bleeding, or tenderness.
As it progresses, the gums may pull away from the teeth, exposing sensitive roots.
This exposure can make the back teeth hurt, especially when eating or brushing.
Tooth Sensitivity in Back Molars
Tooth sensitivity occurs when the protective enamel wears down.
This allows hot, cold, or acidic foods to reach the inner layers of the tooth.
Back teeth sensitivity can cause sudden sharp pain when consuming certain foods or drinks.
Common causes include aggressive brushing, enamel erosion, or gum recession.
Cracked or Broken Back Tooth
A cracked or broken molar can cause ongoing discomfort.
Cracks may develop from biting hard foods, accidents, or teeth grinding.
Sometimes cracks are not visible but still cause pain when chewing.
The discomfort may come and go, making it difficult to identify the problem.
Sinus Infection Causing Back Teeth Pain
Upper back teeth are located close to the sinus cavities.
When the sinuses become inflamed or infected, pressure can cause pain that feels like a toothache.
Sinus related back teeth pain often comes with congestion, headaches, or facial pressure.
Treating the sinus issue usually helps relieve the dental discomfort.
Teeth Grinding at Night
Grinding or clenching teeth, also known as bruxism, places excessive pressure on molars.
Over time, this pressure can lead to tooth pain, jaw soreness, and worn enamel.
Many people grind their teeth during sleep without realizing it.
Morning jaw pain or headaches may be signs of nighttime grinding.
Back Teeth Hurt When Chewing or Biting: What It Means
Pain when chewing is often a sign that something is wrong beneath the surface.
It may indicate a cavity, cracked tooth, or infection affecting the tooth root.
When pressure is applied, inflamed tissues react with pain.
This type of discomfort should not be ignored, as it often worsens over time.
Early evaluation helps prevent more extensive dental issues.
Back Teeth Hurt on One Side: Should You Worry?
Pain limited to one side of the mouth usually points to a localized problem.
This may include a cavity, impacted wisdom tooth, or gum infection affecting a specific area.
Jaw issues or sinus pressure can also cause one sided discomfort.
If the pain persists for more than a few days, it is best to seek dental advice.
Back Teeth Hurt Suddenly: Possible Reasons
Sudden back teeth pain can be alarming.
It may occur due to a newly cracked tooth, exposed nerve, or infection.
Sudden sensitivity can also result from enamel erosion or gum recession.
Any sharp or severe pain that appears without warning deserves prompt attention.
How to Relieve Back Teeth Pain at Home
While home care cannot replace professional treatment, it may help manage discomfort temporarily.
Home Remedies for Back Teeth Pain
Rinsing with warm salt water can help reduce inflammation and cleanse the area.
Applying a cold compress on the outside of the cheek may reduce swelling and numb pain.
Over the counter pain relievers may offer short term relief when used as directed.
Avoid applying heat directly to the affected area, as it may worsen inflammation.
What to Eat and Avoid When Back Teeth Hurt
Soft foods are easier to chew and reduce pressure on sore teeth.
Avoid hard, sticky, or sugary foods that can irritate sensitive areas.
Limiting extremely hot or cold foods may also help reduce discomfort.
Maintaining gentle oral hygiene is essential even when teeth are sore.
When to See a Dentist for Back Teeth Pain
Persistent or severe pain should always be evaluated by a dental professional.
Signs that require prompt dental care include swelling, fever, difficulty chewing, or pain lasting more than a few days.
Ignoring symptoms may allow infections to spread and cause further complications.

Early dental visits often result in simpler and more effective solutions.
How to Prevent Back Teeth Pain in the Future
Preventive care plays a key role in avoiding back teeth pain.
Brushing twice daily with fluoride toothpaste helps protect enamel.
Flossing removes plaque from areas a toothbrush cannot reach.
Regular dental checkups allow early detection of cavities or gum issues.
Wearing a night guard may help prevent damage caused by teeth grinding.
Maintaining a balanced diet and limiting sugary snacks also supports oral health.
Frequently Asked Questions About Back Teeth Hurt
Can stress cause back teeth pain?
Stress may lead to teeth grinding or clenching, which can cause molar pain over time.
Managing stress and using protective dental appliances can help reduce symptoms.
Why do my back teeth hurt at night?
Pain at night may feel worse due to increased blood flow when lying down.
Grinding during sleep can also contribute to nighttime discomfort.
Is back teeth pain always a cavity?
Not always.
While cavities are common, pain may also come from gum disease, sinus issues, or tooth fractures.
A dental examination is the best way to identify the cause.
