A few tips:
Start dental care early and brush baby teeth with a fluoride toothpaste as soon as the first teeth appear.
Do not get used to your children, before falling asleep, drinking milk, fruit juice or a bottle-fed drink. These sugary fluids remain long on the surface of the teeth and can lead to the “tooth decay of the bottle”.
Brush your teeth at least twice a day with fluoridated toothpaste.
And if possible, clean your teeth with dental floss or toothpick once a day. Do not eat in the evening after brushing your teeth, as the saliva flow decreases during sleep.
Visit your dentist about every 6 months for a check-up.
And consult your dentist before resorting to cosmetic products (e.g., whitening agents), which can damage teeth.
