Brushing after breakfast

[Fabsyd]

Hi. Just wondering what is so bad about brushing after breakfast? Is it the act of brushing or is it the chemicals in the toothpaste that react to the acid that could be in the did eaten?

When you eat anything acidic (tomatoes, most fruits/citrus, etc) it etches the enamel surface which makes it vulnerable to mechanical abrasion. It is usually best to rinse after meals with plain water and wait about 15 minutes before brushing to allow the acidity to diminish. It is not necessarily bad to brush after breakfast, but you asked about possible harm from it.
