Tooth decay occurs when plaque bacteria react with sugars in our diet to produce acids which dissolves tooth enamel. If this happens continuously, a hole appears in the tooth called a cavity.
Teeth can be under attack every time you eat something sugary for up to an hour afterwards, therefore try to eat sugary foods only at meal times and between meals only eat foods that do not contain sugar. Cheese, fruit and vegetables are ideal.
Plain water or milk is ideal as a drink as fizzy drinks can dissolve tooth enamel or the sugar in them can cause decay. Sugar free squashes are less damaging to teeth especially if well diluted if water seems tasteless. You can neutralize acids on your teeth by eating something alkaline like cheese afterwards.
Brushing with a fluoride containing toothpaste is best done twice a day before breakfast and just before you go to bed. It is not a good idea to brush just after a meal as enamel is at its weakest and the surface of it can be easily damaged.
Remember many processed foods contain high levels of sugar. Get used to reading labels on foods and drinks; the higher up it is mentioned in a list of ingredients the bigger the amount of sugar it contains. Also remember no added sugar means none has been added but still may contain sugars already in the food in the form of carbohydrates.
Chewing sugar free gum after meals will stimulate saliva which neutralizes acids produced by plaque.
Finally remember it is not the amount of sugar you eat it is how often you eat it in between main meals that is important.
Don’t forget sugary foods not only affect the health of your teeth. Too much sugar can cause heart problems and cause you to become overweight.
