DON’T RINSE YOUR TEETH

SPIT out excess toothpaste but don’t rinse after brushing. ‘Swishing out your mouth straight after brushing as many people do washes away much of the protective fluoride and other beneficial ingredients in toothpaste, thus reducing its effectiveness,’ warns Dr Reena Wadia, a periodontist from RW Perio clinic in London.

But you should always give your toothbrush a thorough rinse with tap water to remove plaque and food debris after use. Some dentists suggest soaking it in antibacterial mouthwash or even running it through the dishwasher to kill off bacteria.

Then store it in an upright position so the bristles can dry (damp bristles are a breeding ground for bacteria).
