Just brush with water only. The taste of the toothpaste can trigger a reaction in the brain which causes precious energy, I think the amount is 25% of the heart energy and blood, will be diverted to the digestion system in anticipation of being fed. So better to be safe than sorry, just brush with water.
I would also go without the deodorant especially, simply because the skin is part of the elimination system and should be left alone to eliminate. Anything you add to the skin will be absorbed through it. The only thing you should be adding is sunlight which is beneficial apparently. If you can wash your body with a face washer only too- no soap- that would be best as well. The shampoo would also be absorbed to some extent.
How diligent you are is up to you. The skin business is more opinion than the toothpaste, that is more bound in fact.
