Hello. This question is incomplete. The full question is:
John Allen is scheduled for a diagnosis on tooth #20. This is Mr. Allen's first time to the endodontist, and his subjective comments describe pain when chewing on the affected side and a constant dull pain lasting for approximately a week.
How do you think Mr. Allan knew ro come to a endodentist for dental treatment?
Answer:
Mr. Allan learned that he needed treatment with an endodentist through consultation with a general dentist.
Explanation:
It is likely that when Mr. Allan felt discomfort in the tooth, he made an appointment with the general dentist. Through the analysis of Mr. Allan's case, the general dentist realized that Mr. Allan had a very specific problem and that he should be treated with a professional, someone who could deal with the problem directly and more effectively. For this reason, Mr. Allan's dentist suggested that he look for an endodentist who could help him, since Mr. Allan was having problems with dental pulp.
