An aching tooth is often an indication of infection and should be investigated by your dentist as the problem will not simply resolve itself. However, teeth can sometimes be infected without resulting in any pain, sensitivity or swelling of the gums.
Tooth infections occur for a number of reasons including gum disease and cavities. But these take time to develop and are usually accompanied by mild to severe pain.
Tooth infections that have no noticeable symptoms can often be attributed to bacteria that has:
- Destroyed the tooth's inner pulp and connecting nerve tissue
- Caused the entire tooth and the underlying nerves to die
- Triggered an immune response from the body that prevents or masks any pain
Tooth infections often begin with some form of trauma to the tooth that results in a crack, chip or break. Although the damage may seem insignificant, any such trauma should be discussed with your dentist.
Even the smallest hole or crack will allow harmful bacteria to enter and spread to the inner pulp and down to the root. Symptomless tooth infection is impossible to self-diagnose which makes regular check-ups at the dentist of extreme importance.
Early detection is vital if the infection is to be contained and treated before the situation deteriorates -- and becomes more expensive to fix. Read more in the article at https://yourdentalhealthresource.com/can-a-tooth-infection-be-painless/
