Sudden Tooth Pain? Here’s What Might Be Causing It Sudden tooth pain can be alarming and may indicate various underlying issues. Here are some possible causes: Tooth Decay: Cavities can expose the sensitive inner layers of your tooth, leading to pain. Gum Disease: Inflammation and infection of the gums can cause discomfort, especially if left untreated. Dental Abscess: A pocket of pus caused by a bacterial infection can develop at the root of the tooth, causing severe pain. Tooth Fracture: Cracks or fractures in the tooth can expose the nerve, resulting in sharp pain when chewing or biting. Sinus Infection: Sometimes, a sinus infection can cause pain that feels like a toothache, especially in the upper back teeth. Bruxism (Teeth Grinding): Grinding your teeth can lead to tooth sensitivity and pain. Impacted Wisdom Teeth: When wisdom teeth don't have enough room to emerge, they can become impacted, causing pain and swelling. If you're experiencing sudden tooth pain, it's important to see your dentist for an evaluation to determine the cause and appropriate treatment.
