Your dentist will tell you that certain foods like snacks and fizzy drinks are just naturally bad for teeth but there are others that can also be damaging unless carefully monitored. Some food and drink to be wary of include:
• Bread. Saliva converts the starch in bread to a sugary paste and this can stick to teeth and lodge in crevices.
• Dried Fruit. Healthy but sticky, dried fruit sticks onto and between the teeth depositing large amounts of sugar.
• Alcoholic drinks. Alcohol dries the mouth and reduces the amount of saliva significantly.
