Brushing your teeth before breakfast could weaken enamel, according to a leading dentist. Dr Lawrence Smith, a Bupa dentist at the Bryer Wallace practice in Knightsbridge, advises waiting at least 30 minutes after eating before brushing. 'Brushing before breakfast can weaken your enamel and any acidic or sugary foods consumed afterwards may have a negative effect,' he said.
If waiting is not possible, Dr Smith suggests using a fluoride-fortified mouthwash before eating or a soft-bristled toothbrush afterwards to minimise abrasion. He also recommends avoiding mouthwash immediately after brushing, as it can remove concentrated fluoride from toothpaste. 'It is best to wait at least 30 minutes before using mouthwash,' he added.
Dr Smith highlighted common culprits for tooth staining, including red wine, tea, coffee, berries, and curry, due to their tannins or vibrant colours. He drinks water after coffee to neutralise acids. While sparkling water is less acidic than sugary drinks, he cautioned that sugar-free fizzy drinks contain carbonic acid that can weaken enamel.
For optimal oral hygiene, Dr Smith uses an electric toothbrush and fluoride toothpaste, and flosses daily. He visits a hygienist every six months and uses at-home whitening kits. He warns against aggressive brushing, which can damage enamel and gums, and advises against chewing ice, which can crack teeth.
