A biological cleaning is not more painful than a traditional cleaning. If you have moderate to severe gum disease or sensitive teeth, a cleaning (whether traditional or biological) may be uncomfortable due to inflammation of the gums or sensitivity of the teeth. However, there are ways to work through this discomfort such as topical gel, or splitting the appointments into multiple sessions. If discomfort is a result of gum inflammation, regular cleanings will help to reduce this inflammation and each cleaning will become easier and more comfortable as the gums become healthier.
