If I have pericoronitis, than when should I get it checked out by a dentist??

Without any improvement within 5 days, usually after that you should make an appointment with your dentist.

Within 5 days, is when you should get it checked out

Could you elaborate?

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
