A toothache can strike unexpectedly, disrupting your day and causing significant and frustrating discomfort. Some of the most common toothache triggers include: Decay - Cavities form on your teeth due to bacterial buildup. This buildup damages the enamel and causes sensitivity and pain. - Gum disease - When your gums swell up as a result of plaque and tartar accumulation, they expose the delicate roots of the teeth. This exposure causes significant discomfort. - Abscess - This painful condition is caused by a bacterial infection that creates a pus-filled pocket around the tooth. - Fractures - Broken or cracked teeth can expose the surrounding nerves and pulp, causing severe pain. - Teeth grinding - Grinding your teeth frequently, particularly while you sleep, can wear down the enamel and cause tooth sensitivity. - Impacted wisdom teeth - Wisdom teeth that don't have enough space to emerge properly become impacted, leading to pain, swelling, and infection. - Temperature sensitivity - If your tooth enamel is compromised, consuming hot or cold foods and beverages can cause a toothache. Your most effective lines of defense against toothaches are proper oral hygiene, routine dental exams, and a healthy lifestyle. If you experience a toothache, it’s recommended to consult a dentist promptly to determine the underlying cause of your discomfort.
