Common Causes of Sudden Tooth Pain

Top Reasons You May Develop Sudden Tooth Pain
Tooth pain can strike at any time—whether you’re enjoying a meal, waking up in the middle of the night, or simply going about your day. Sudden tooth pain can be unsettling and may be a sign of an underlying dental issue that needs immediate attention. At Friendly Dental, we know how disruptive and uncomfortable unexpected tooth pain can be. Understanding the root causes can help you take the right steps to find relief and prevent future problems.
If you’re experiencing sharp or persistent pain, don’t ignore it—reach out to the best dentist in Aberdeen, NJ for prompt and professional care.
1. Tooth Decay
One of the most common causes of sudden tooth pain is tooth decay. When cavities form, they can expose the sensitive inner layers of your tooth, including the dentin and pulp. This can lead to sharp or throbbing pain, especially when eating or drinking something hot, cold, or sweet.
Early-stage cavities might not cause noticeable symptoms, but once the decay reaches deeper layers, it can trigger intense discomfort. Regular dental checkups can catch these issues before they progress.
2. Dental Abscess
A dental abscess is a serious infection that forms at the root of a tooth or in the gums. This can cause severe, throbbing pain that may radiate to the jaw, ear, or neck. Other symptoms include swelling, a foul taste in the mouth, fever, and sensitivity to pressure.
Dental abscesses require immediate attention. If left untreated, the infection can spread to other areas of the body. Friendly Dental offers emergency dental care to treat infections quickly and effectively.
3. Gum Recession
Receding gums expose the sensitive roots of the teeth, leading to increased sensitivity and sudden pain. You may feel discomfort when brushing, flossing, or consuming hot or cold foods.
Gum recession can result from gum disease, aggressive brushing, or even genetics. Our team at Friendly Dental can assess your gum health and provide treatment options to protect your smile.
4. Cracked or Fractured Tooth
A cracked or fractured tooth can cause sudden, sharp pain—especially when biting down. Cracks can be hard to detect and may not always be visible to the naked eye. You might also notice sensitivity to temperature changes or intermittent discomfort.
Even a hairline crack can allow bacteria to enter the tooth and lead to infection, so it’s important to see your dentist right away if you suspect damage.
5. Tooth Sensitivity
Sometimes, sudden tooth pain isn’t due to a major dental issue but rather increased tooth sensitivity. This can be caused by:
Worn enamel
Gum recession
Using whitening products
Brushing too hard
Desensitizing toothpaste and fluoride treatments can help, but it’s always best to consult with the best dentist in Aberdeen, NJ to rule out other potential issues.
6. Impacted Wisdom Teeth
If your wisdom teeth are starting to come in and don’t have enough room, they can become impacted—trapped under the gum or pressing against other teeth. This pressure can cause sudden pain in the back of your mouth or jaw.
Regular dental exams can monitor the development of wisdom teeth and help determine if removal is necessary.
7. Sinus Infection
Surprisingly, sinus infections can cause pain that feels like it’s coming from your teeth—especially your upper molars. When your sinuses become inflamed or filled with fluid, they can put pressure on nearby nerves.
If you have tooth pain along with sinus pressure, congestion, or a headache, it could be sinus-related. A dentist can help determine the true cause and rule out any dental conditions.
8. Teeth Grinding (Bruxism)
Grinding or clenching your teeth—often during sleep—can lead to worn enamel, tooth fractures, and jaw pain. Over time, this habit can cause tooth sensitivity and sudden discomfort.
A custom mouthguard from Friendly Dental can protect your teeth and help alleviate pain caused by bruxism.
