Toothaches happen when the nerve in or around a tooth becomes irritated. According to recent information, the most common reasons for this irritation include dental infection, tooth decay, injury, or tooth loss. Pain can also occur following a tooth extraction.
Common Causes of Toothaches
Here's a breakdown of common causes of toothaches, based on the provided information:
- Dental (Tooth) Infection: Infections can inflame the nerves and tissues around the tooth.
- Decay: Cavities expose the inner layers of the tooth, irritating the nerve.
- Injury: Cracks, chips, or other damage can expose the nerve.
- Loss of a tooth: The empty socket can be sensitive and prone to infection.
- Post-Extraction Pain: The area where a tooth was removed can be painful as it heals.
In summary, anything that irritates the nerves within or surrounding a tooth can lead to a toothache.
