How much bleach gel is used for teeth cleaning?

None: I can't say i've used bleaching gel for normal cleanings. We normally scale the teeth with either hand scalers or an ultrasonic scaler and then polish with a toothpaste-like medium.

None: Bleaching gel is used to whiten the internal part of the tooth or the dentin. Cleaning is done with various forms of toothpaste. If you are bleaching, the most common mistake is to use too much bleach. If your gums are irritated and painful after bleaching you are using too much. The bleach should cover the teeth but not touch the gums.
