What causes decay?

Sugar and refined carbohydrates are used by plaque bacteria, producing acids which attack the tooth. Acid may penetrate below the tooth surface, and dissolve sorne tooth minerals.

Natural recovery (or remineralisation) will usually replace much of the tooth mineral lost below the tooth surface. This ʻattack and recoveryʼ process occurs every time we eat.

lf the ʻattackʼ outweighs the ʻrecoveryʼ process over longer periods of time, the damage becomes visible and looks like chalky ‘white spotsʼ on the teeth. Early ʻwhite spotʼ decay can often be seen on teeth along the gemlike. If the acid damage continues the white spot turns into a hole in the tooth.

Fluoride (from water and toothpaste) helps toughen the teeth to resist acid attack at the tooth surface, and also helps in the natural recovery rebuilding the damaged tooth.

To control and reverse dental decay takes some effort, but most gains can be made by developing a few routine habits.


Why does decay happen?

Not enough fluoride

SUGAR: too much - too often

Soft drinks, cordial and sports drinks, tea and coffee with sugar, sweets and highly sugared snacks e.g. sweet biscuits, health bars.

Dry mouth, which may be caused by some medications (e.g. anti-depressants), drugs and extreme stress

Saliva helps to protect our teeth by diluting the acid that forms after eating. Dry mouth may increase the chances of tooth decay.
