Thank you in advance for your help. I have tried to prepare this email by looking up proper terms. I am a lay person.
In June 2009 a dentist performed the advanced cleaning procedure they identified as a full mouth debridement, 4355. The dentist also measured the distance between the enamel and the gum. This was painful as the measurement device pressed into what I assume was soft enamel or dentin.
The reason for my concern and my question here follows. Before the cleaning, my gums completely filled the gaps between my maxilla 7, 8, 9 and 10. After the cleaning, between 9 and 10, a 1.5 millimeter gap exists. And, between 9 and 8, and between 8 and 7, a 0.5 mm gap exists. In other words it appears that the dentist created gaps during the cleaning process, and accelerated the process of receding gums. I definitely had a lot of blood when I rinses after the cleaning. Did the dentist make a mistake?
The dentist recommended that I come back for the second part of the cleaning including having the undersides of my gums cleaned. Another dentist during another previous appointment recommended the same. Based on the apparent damage to my gums, I have ignored this. I have not had my teeth cleaned since.
