A simple filling is often sufficient to treat a cavity but this is not always the case and there will be times when root canal treatment is the only solution.
Your dentist will evaluate the problem and may advocate root canal work if the cavity:
– Is too deep or big
– Has penetrated down to the nerve
– Is causing severe pain or sensitivity
Taking good care of your teeth is paramount but the good news is that “root canal can be performed with no pain” and the tooth will be saved from extraction. A full article on the topic can be read at https://yourdentalhealthresource.com/is-a-filling-okay-or-will-i-need-a-root-canal/.
