A woman comes to the office to have a gold crown on tooth #3 placed permanently. However, she mentions that she has been experiencing a dull ache and temperature sensitivity in that area for the past 5 days. After the dentist examines the area, he informs the
dental assistant that he will cement the gold crown on tooth #3 with temporary cement. Why is this change in cementation needed?

The change in cementation from permanent to temporary may have been due to an infection or even a damage in the tooth cavity which she felt as a dull ache and temperature sensitivity.

Cementation is the process of using a certain dental cement to a tooth for restorative purposes. This process is used when there is the need to keep a damaged or loose tooth in place so as not to make it empty.

Dental cementation is done if a person wants to retain his/her tooth, or if the tooth is infected or damaged. This allows the tooth to be treated, with the dental cement acting as a cavity filling for the damaged tooth.Moreover, cementation helps restore the tooth and makes it easier for a person to consume foods.There are two types of dental cementation- temporary and permanent.While temporary cementation may be used for replacements or fillings with an easy removal process, permanent ones are less advantageous as they are hard to remove after the cement sets in.In the case of the woman who wants to have her gold crown permanently set, the dentist's decision to go for temporary cementation is because of the "dull ache and temperature sensitivity" that she experienced.Since these issues are detected in the tooth, there is a risk in permanently cementing the crown. This is because, with the ache and sensitivity issue, there might be a chance of infection or other dental issues, which can be hazardous if permanent cementation is done.

So, the dentist's decision to do temporary cementation rather than a permanent one is to ensure that in case of any infection, the removal process can be easily done and the infected tooth treated.
