As a health care worker this would be great for very fragile or palliative clients where brushing effectively just isn’t possible. Fragile clients will often do a poor job or if you help them they don’t always tolerate how hard and long you need to brush to be effective. Not to even mention flossing. And with palliative patients they can often be bed bound and unconscious to you can’t really get in with a toothbrush and water and brush properly. Instead they get a small piece of foam attached to a stick basically and you rub it around their mouth and get any big chunks out. Very poor effectiveness. For me good mouth care for the palliative clients would be really nice to see.
