Using toxins is bad!
But why is it done? The answer is simple: time!
You walk into the dentist’s office with a toohache, but without an appointment, since you cannot plan for a toothache. But getting rid of the pain for good requires thorough root treatment, for which there is just not enough time right then and there. So the tooth is opened up and a toxin injected in the hope that the tooth, and you as a patient, will not cause any more trouble before your next appointment. This process is known as „incomplete“ root canal treatment.

This need not be a problem, sometimes a dental nerve just cannot be filled immediately, it is necessary to perform intermediate steps. But a toxin should not be administered, as it also ends up damaging healthy tissue, e.g. the bone around the root tip, eventually leading to a root tip resection. Instead of toxins, it is also possible to use medicines such as CaOH – Calcium hydroxide!

Regular check-ups can help prevent both – toothaches and incomplete treatment!
