How can I remember the root canal morphology of every single permanent tooth?

You can't. Most up-to-date dentists use digital pictures of teeth, that cup abuse much less exposure to radiation, and are permanently stored on the computer. They are accessible any time to the dentist, or dental assistant, or hygienest; and very importantly can be transmitted to any other specialist, person, including you, that you authorize.
Impossible. Root canal morphology can vary to infinite degrees in different teeth and people...Dentists are trained to know the basic morphology of certain teeth, and then how to read radiographs of specific teeth. But actual root canal morphology is not known for sure until the actual tooth is opened and the root canal system explored/cleaned/filled.

Hi, My daughter is 7 year old and the dentist is suggesting to do root canal on her 14th tooth, saying it would be better as this is a permanent tooth.

Child dental care. Tooth #14 is the upper left 1st molar. This tooth is part of the overall foundation of the bite. Root canal treatment would only be necessary if the nerve of the tooth is either inflamed or infected. Doe your daughter have pain? Does she have sensitivity to hot and cold food or very sweet food? If you are unsure of the need for root canal treatment, take her to an endodontist (root canal doc) Read more...
Yes. #14, the upper left 1st (6 year) molar, is an exceptionally important tooth. As it is a permanent tooth, there is no tooth under the gums to come in to replace it. At 7 the root canals will still be very wide, and as such it is recommended that she see an Endodontists, a root canal specialist, for the treatment. Also, bas she is 7, see an Orthodontist to see if the tooth can be replaced. Read more...
RCT #14 ? Generally speaking it would be very important to save tooth #14 (upper left first molar) rather than taking it out. Important that the tooth be treated by an Endodontist at her age. Also the tooth would need to be restored properly (a crown when older), but something strong at this age or she may loose the tooth after all. Make sure that she is in good hands and you trust the dentists involved. Read more...
