♠Lestat is confused as to why you’re directing your questions to me, he’s trying to force me to answer what he would answer, but I am pointedly ignoring him. 

It’s not of great interest to me, but I will note that he has gone to considerable research about brushing teeth, he and Daniel bring home these little “self-care” packages: toothpaste of different flavors, devices that spray water or have vibrating bristles, and they test these items out on fruit or each other. I sometimes participate. 

There are nights that Lestat returns to me from hunting and his breath is truly atrocious, so he has to do some level of cleansing to be permitted within my personal space. I follow the same etiquette for his sake.

In the past, we would have a basin and would wash before going out, and before going to sleep for the day. Little mortal rituals like these keep us feeling that we have some semblance to humanity still, and perhaps, it is also restorative in the way many acts of taking care of oneself are restorative. 

However, it’s not necessary for us to brush our teeth in much the same way, I suppose, as it is unnecessary for wild animals. Perhaps it’s because we do not consume cooked meat, refined sugars, or flavored drinks. Fareed suggests that we have saliva with a high Ph value, which protects the enamel from demineralizing and thus prevents cavities.
