Rinse your mouth and teeth with copious water to remove residual whitening materials, but wait for a couple of hours before brushing.
Short answer, Yes. The whitening process opens the “pores” in the teeth to allow the chemicals to infiltrate and whiten the structure. It does not damage or weaken the tooth structure. In an ideal scenario I recommend you use a topical fluoride gel immediately after removing the whitening trays. To do this, remove the trays and rinse them well, then either place the fluoride gel in the trays or brush it directly onto your teeth, then place the whitening trays back on your teeth for about 20 minutes. This will help take advantage of the open structure of your teeth and allow the fluoride to integrate and strengthen your tooth structure. After that, as long as you are using a soft or ultra-soft toothbrush, brush away.
I recommend brushing before you insert the trays. then when finished whitening just rinse your mouth out and drink water to rehydrate the teeth. You can brush after whitening but I would make sure to use a toothpaste that is white in color.
You should brush your teeth before using the whitening trays and after using the trays.
I would suggest that after you remove the trays, just spit out the excess bleach. If you brush your teeth you may stop any residual action of any bleach left on the surface of your teeth.
I hope this helps.
It is best NOT to brush your teeth after the whitening. 

You should brush your teeth at least 6 hours after whitening trays. The whitening procedure has an effect on enamel and may make it more porous, so when you brush right after, you may strip off some enamel. Waiting a few hours allows for the enamel to re-mineralize through saliva.
You must brush and floss yr teeth prior to bleaching your teeth. After your bleaching, you need to rinse your mouth thoroughly, but not required to brush your teeth.
No brush and floss PRIOR
