About the Symptom
Toothache describes the painful sensation in or around a tooth.
When to See a Doctor
Seek professional care if you experience any of the following symptoms
- Fever
- Swelling of the affected area
Possible Causes
Generally, Toothache can be related to:
- Dental Caries
Dental caries occur when the hard outer layer of your tooth, the enamel, gets destroyed, sometimes forming small holes or cavitations. Common causes include eating and drinking sugary foods, frequent snacking, dry mouth and poor oral hygiene.
- External Dental Fistula
A dental fistula is a pathway formed between the oral cavity and the bone surrounding the affected tooth to drain an infection. It is typically found on the gum tissue near the affected tooth. It can look like a pimple in the gums and mainly occurs after an abscess due to trauma or infection.
- Subacute Thyroiditis
Inflammation of the thyroid gland which causes high levels of thyroid hormone in the body. It usually occurs after a viral infection. It presents as pain in the neck because of the swollen and inflamed thyroid gland. Can also have difficulty swallowing, hoarseness, fatigue and fever. It can also go on to cause symptoms of high thyroid hormone such as weight loss, increased bowel movements, palpitations, sweating.
- Trigeminal Neuralgia
- Temporomandibular Joint Osteoarthritis (TMJ)
- Migraine
- Shingles (Herpes Zoster)
- Sinusitis
- Ear Infection
Related Serious Diseases
Sometimes, Toothache may be related to these serious diseases:
- Myocardial Infarction (MI) / Unstable Angina
These are often grouped together under the term "Acute Coronary Syndrome" (ACS) and are potentially life-threatening. This occurs when a blood vessel supplying the heart is blocked, usually by a blood clot. Risk factors include high cholesterol, high blood pressure, a sedentary lifestyle, diabetes, and a family history of cardiovascular diseases (e.g., stroke, heart disease).
