Find some scientific evidence to back up the view that you need to actually brush your teeth. If he still doesn't believe that, then tell him having decayed teeth isn't fun. His mouth is going to get real nasty, real soon.

#46 Cavities aren't the only problem. His breath will reek and his tongue will get plaque too. He'll be more likely to get mouth infections. Also some people are prone to get plaque growth in the folds of their tonsils and sometimes clumps fall out and there's this awkward moment where your throat can't decide if you should cough it up or swallow it. Which is why there's mouth wash.

Actually, he is totally wrong. The only way for toothpaste to damage your teeth is to brush directly after you're finished eating. This is because the acids in your food are at their peak, and will react to the acids in the toothpaste, hurting your teeth as a result. So wait 10-15 min before brushing, because that is the only way your teeth can be damaged by toothpaste.

Had a former teacher who was kind of...quirky. She had a thing about brushing her teeth A LOT, but her dentist told her she had to stop brushing so excessively because she was literally thinning down her teeth. Of course I doubt most people are obsessive about it like she seemed to be.

23 - Fluoride in the toothpaste has two main roles. First, it's incorporated into the inorganic crystals that make up the enamel, converting them from hydroxyapatite to fluorohydroxyapatite. Fluorohydroxyapatite is much more resistant to the acids that the bacteria make than hydroxyapatite is, so it's harder to erode away during an acid attack. Secondly, the fluoride is transported in small amounts into bacteria in the form of hydrofluoric acid, which kills the bacteria. If you use "natural" ingredients (fluoride is natural), you miss out on both of these things, leaving your teeth more vulnerable to decay. Use a soft bristled toothbrush and a fine grained toothpaste or toothpaste for sensitive teeth (not whitening!) to avoid wearing down teeth while brushing.
