The most common cause of tooth pain or toothache is nerve irritation, but there are various other factors that can contribute to one’s toothache. Some additional factors are gum disease, plaque, infections, damaged teeth, wisdom teeth, rotting teeth, bruxism, and temporomandibular joint (jaw joint) disorders.
Sometimes, the pain felt in one’s tooth actually originated elsewhere, but the pain radiated outwards to towards it. This can occur when there is an issue with one’s ear, sinuses, nerves, muscles, or TMJ. Sensitivity to cold or hot exposure to the tooth can be a sign of a potential issue.
Thankfully, the majority of these issues described above can be alleviated through basic oral hygiene – daily brushing and flossing. Make sure that the products you are using in your oral routine contain fluoride and xylitol, such as toothpastes or mouthwashes.
You must also visit the dentist every few months, typically two times a year and sometimes more depending on the condition of your oral health.
