A visibly noticeable benefit of Brexit is that we will be able to have whiter teeth. The problem lies with EU bureaucracy. The EU allows less than 0.1% of hydrogen peroxide in over-the-counter products, which means that their effectiveness is low. In America, up to 10% is considered safe, and Americans have whiter teeth. A further benefit of a post-Brexit move to allow effective home whitening kits would be to reduce the high income inequality caused by dentists charging high fees for whitening while lobbying Brussels to maintain the low concentration limit for home products.

And white teeth are the only benefit I can think of in this extraordinary example of casual self-harm, called Brexit.
