Cavities or Wisdom Teeth? Understanding Why Your Back Teeth Hurt

Back tooth pain can sneak up on anyone. One day you’re enjoying your lunch, and the next you’re wincing with every bite. It’s natural to ask: Why do my back teeth hurt? The truth is, there isn’t one simple answer. Pain in the back teeth can come from a variety of causes, from common cavities to impacted wisdom teeth.

The good news is that understanding the reason behind your discomfort helps you know what treatment to seek and how to prevent future problems. Let’s break down the most common reasons your back teeth may hurt, what else could be happening, and how dentists can help.

Common Causes of Back Tooth Pain

Back teeth work the hardest. They crush, grind, and chew—so they’re more likely to develop problems over time. Here are some of the biggest culprits:

• Cavities
• Tooth decay is one of the major causes of pain. When bacteria eat away at the enamel, sensitivity and sharp pain follow, especially when eating sweets or drinking cold beverages.
• Wisdom Teeth
• If you’re in your late teens or twenties, erupting wisdom teeth might be to blame. These molars can push against other teeth, grow at odd angles, or become impacted, all of which cause throbbing pain in the back of your mouth. Many patients need wisdom teeth extraction in Calgary, AB, to relieve pressure and prevent long-term issues.
• Gum Problems
• Gum inflammation or early gum disease can cause soreness near the roots of back teeth. Swelling and bleeding when brushing are also common warning signs.
• Tooth Fractures
• Cracks in molars are more common than you think. Biting on foods like ice or nuts can lead to tiny fractures that expose sensitive inner layers.
• Old or Failing Fillings
• Back teeth often have fillings from earlier cavities. If those fillings wear down or loosen, they may expose the tooth underneath and trigger pain.

Other Possible Reasons Your Back Teeth Hurt

Sometimes, the cause isn’t obvious. Here are a few additional possibilities you might not think of right away:

• Clenching and Grinding (Bruxism)
• Many people grind their teeth at night without realizing it. This puts constant stress on the back teeth and leads to soreness or even cracked enamel.
• Sinus Pressure
• Believe it or not, sinus infections can mimic tooth pain. Because the sinuses sit close to the upper molars, pressure in this area may feel like dental pain.
• Food Trapped Between Teeth
• It may sound simple, but trapped food particles can cause surprising discomfort. Left untreated, they may irritate gums or contribute to decay.
• Jaw Alignment Issues
• If your bite isn’t lined up properly, certain molars may take on more force than others. Over time, that imbalance can cause pain and uneven wear.

Treatment Options for Back Tooth Pain

The right treatment relies on the root cause. Dentists first run exams, possibly with X-rays, to figure out what’s happening. Here are some treatments you may encounter:

• Fillings for Cavities
• If decay is caught early, dentists clean the tooth and restore it with durable materials. Many patients in the area benefit from composite fillings in Calgary, AB, which are tooth-colored and blend naturally.
• Wisdom Tooth Removal
• Impacted or painful wisdom teeth are usually extracted. This prevents future infections, crowding, and persistent pain.
• Gum Care
• Professional cleanings and deep scaling help control gum disease and protect back teeth from further damage.
• Crowns or Onlays
• Severely cracked molars may need protective crowns to restore function and strength.
• Nightguards
• For patients who grind or clench, a custom nightguard relieves pressure and protects the enamel.
• Lifestyle Adjustments
• Sometimes small changes help: improving brushing and flossing, reducing sugary snacks, and staying hydrated.
