However, there are other factors that may contribute to a toothache, such as:
Dental sensitivity: Some toothaches can be from teeth whitening. Generally, this type of toothache is temporary and is caused by the irritation of dental nerves from the active ingredient in the whitening formula.
Cracked or chipped tooth: A cracked or chipped tooth can lead to a toothache. Emergency dental care may be required in order to reduce your pain and restore the damaged tooth successfully.
Sinus infection: A sinus infection can cause pressure in the sinus cavities, temporarily leading to toothaches until the infection is resolved.
Abscess: A dental abscess is usually caused by a bacterial infection in the nerve of a tooth. A root canal or extraction is required to resolve this dental problem.
