Sugar free gum does not have any sugar in it. The taste is added using natural sweeteners such as Xylitol, and therefore the gum does not cause tooth decay. Xylitol can be found in some berries, fruit, vegetables and mushrooms. Xylitol is usually made from birch bark, it prevents the bacteria sticking to your teeth and can help replace minerals found in enamel.
Chewing sugar free gum can help protect your teeth and gums in between meals when it may not be possible to brush your teeth.
Your teeth are more at risk after you have eaten. The acid is produced by plaque bacteria, and the sugars in our food and drink, and it slowly dissolves away the enamel and dentine of the tooth, to produce a hole or cavity.
You can reduce this acid attack by chewing sugar free gum, as it helps the mouth produce more saliva- the mouth’s natural defence against acid. Acid is found in the things we eat and drink, such as citrus fruit, fruit juices and fizzy drinks. These start to eat into the enamel, and remove some of the minerals making up the enamel. Chewing sugar free gum helps us produce more saliva therefore helping us reduce this type of attack.
It takes about one hour to replace the minerals that the enamel has lost. Chewing sugar free gum for 20 minutes after eating or drinking can increase the flow of saliva, and help replace the minerals more quickly.
