What is an old root canal?
Old root canal is not a strict name. The correct term should be the root canal after root canal treatment, which we call ‘old root canal’. In fact, after root canal treatment, only the root canal cavity is left inside the tooth and the dentist has removed the pulp. The root canal cavity contains only the filling and it can no longer be considered a root canal.Old root canal infection symptoms
Old root canal infection symptoms
Weakness in chewing
The old root canal is infected, but the pulp has been removed. Pulpitis does not reoccur, so the patient does not feel pain. However, the inflammation spreads to the gum area, and the gums affect the teeth. The tooth will become abnormally floppy and will not have enough strength when chewing food.
A toothache does not occur with a really old root canal. If the dentist gets sidetracked while removing the pulp and the pulp is not completely cleaned. The tooth will still develop pulpitis at this point. During an acute attack of pulpitis, the pressure inside the tooth is so high that the patient feels a burst of swelling and pain coming from the location of the tooth. In severe cases, the patient’s cheeks may swell up and even affect speech.
There are abnormal sounds
Bacteria that infect the tooth have a very powerful penetrating power. Therefore, the filling left during root canal treatment can be destroyed by bacteria. But it takes some time for the bacteria to destroy the filling. It takes six months after the root canal treatment for the patient to gradually feel the filling being destroyed. There is also a possibility that the tooth chews food with too much biting force and the root of the root canal breaks off. In both of these cases, the patient will feel an abnormal ringing in the tooth.
What causes old root canal infections?
Bacteria are the biggest enemy of teeth. And bacteria like unclean oral environment the most. After root canal treatment, the patient’s pain disappears. Patients also do not pay attention to oral cleaning, and the oral environment gradually becomes suitable for bacteria to multiply. After the bacteria multiply to a certain number, the old root canal is re-infected by bacteria.
How to prevent old root canal infection
If the oral cavity is not suitable for bacterial reproduction, the old root canal will not be infected. Patients should use mouthwash and other products that clean the mouth after meals. Brush your teeth more than three times a day so that bacteria cannot multiply in your mouth.
