The main reason for the staging is to prevent your pet from being under anaesthesia for an excessively long period of time (the charting, scale and polish, and full mouth x-rays can take up to one hour alone)
Extended anaesthetics can lead to low blood pressure (hypotension), as well as the development of a reduced body temperature (hypothermia), both of which can be harmful to your pet’s anaesthetic safety and recovery.
Two planned, shorter procedures increase the likelihood of smoother and timelier recovery at both stages.
It also allows for proper planning of the required oral surgery, rather than unexpected diseases being identified during dental radiography, and these having to be addressed immediately.
It also allows for proper planning of appropriate and pre-emptive pain relief, which is more effective if given ahead of the time needed.
Performing a Stage Two on a separate day allows the oral surgery to be performed in a cleaner environment, rather than immediately after the descaling process.
