If you brush teeth in bed, then once finished swallow the leftover toothpaste before falling asleep, is this bad over a long period of time?

I'm specifically asking about the health effects to the teeth of not rinsing, but also any other negative health effects to the body.

The toothpaste in question is Sensodyne.

Yes, and yes. Sensodyne contains fluoride (which is a neurotoxin; such as lead, cadmium, and arsenic).  Therefore, I would say yes, it is bad to swallow this toothpaste, leave any reside on your teeth, or even to use it at all.

Concerning other health effects; I consider that ingesting only food is a critical step toward optimum health.  If the toothpaste were composed of things resembling food, such as hydrogen peroxide and baking soda, then toxicity would be of nil concern.  You could also use plain hydrogen peroxide and omit the baking soda. I use only straight 3% hydrogen peroxide.  It seemed rather strong the first many times I brushed with it, leaving many small and mostly painless white spots on my tongue and gums, but now it seems largely comparable to plain water.

    Welcome to health SE :-) While you have provided some references, most of your claims are not substantiated by them. The statement that using toothpaste at all is bad for health is a very strong one and calls for a reference. Besides, your first reference is about fluoride in water, which is very different from fluoride in toothpaste (because toxicity largely depends on doses, and we ingest much more water than tooth paste). Also, if you recommend an alternative to conventional oral hygiene, you should provide references for that as well. Personal experience doesn't cut it. – Lucky Apr 27 '16 at 3:15

    This answer goes against the majority of recommendations by dental experts. It ignores the marked difference between fluoride amounts in toothpaste and the level needed for toxicity. It recommends practises with noteworthy potential for negative outcomes. – Nij Jun 30 '16 at 14:16
