Cranberries ‘block tooth decay’ besides bladder infection
Cranberries may help prevent tooth decay and cavities, research suggests. Scientists have found a compound in the fruit can stop bacteria from clinging to the teeth, blocking the formation of damaging plaque deposits.
However, researcher Dr Hyuan Koo warned many cranberry-containing products were loaded with sugar and consuming large amounts could lead to tooth decay.

Cranberries can be enjoyed, they should be limited to mealtimes only to avoid potential problems

Dr Koo said people should not eat or drink excessive amounts of cranberry-containing products in an attempt to improve their dental health.
He said many cranberry products contained large amounts of sugar, which is the leading cause of tooth decay.
In addition, the fruit contains a natural acid that can strip away essential minerals in the teeth.

He said: “Scientists believe that one of the main ways that cranberries prevent urinary tract infections is by inhibiting the adherence of pathogens on the surface of the bladder.
“Perhaps the same is true in the mouth, where bacteria use adhesion molecules to hold onto teeth.”
Dr Nigel Carter, chief executive of the British Dental Health Foundation, said: “Cranberries are naturally very acidic, while manufacturers also tend to add sugar to cranberry products.
“Every time you eat or drink something acidic the enamel on your teeth is softened temporarily.
“If given time to recover, then your saliva will neutralise this acidity in your mouth and restore it to its natural balance.
“However, if this attack happens too often the mouth does not have the chance to repair itself and tiny particles of enamel can be brushed away. This is called erosion.
