If your clean was a part of a routine maintenance appointment, it is not unusual to feel some sensitivity to both hot and cold afterward. This will subside within the next 2 days. If you had moderate to heavy build-up on your teeth the sensitivity can last for up to 3-4 days.
If your clean was treatment for gum inflammation, they will feel a little tender for a few days following the appointment. To aid in healing and improved gum health you can rinse your mouth 2 times per day with warm salty water
Patients can experience some bleeding on brushing and flossing for a day or two after having a clean. This is due to your body reacting to the increased bacterial load in the mouth. Do not let this deter you from your usual daily brushing and flossing.
If you are considering any whitening treatments after your clean procedure, it is best to wait for 2-3 days at least, or until any sensitivity has subsided, before commencing treatment.
