How eating and drinking habits affect our teeth
Eating affects your oral health
The reality is our eating habits play a major role in tooth decay, which is
a diet related disease. Sugars in the food and drinks we eat are taken up
by bacteria, producing acids that attack the outer layer of tooth enamel
to cause decay.
Our saliva helps our teeth recover from these attacks through a process
neutralising the acids. However, if we frequently snack between meals,
there is no rest period for teeth to undergo this recovery process, which
means that, over time, a cavity forms as a result of these sustained acid
Water, water everywhere
Drink it up! It’s calorie free, there are no ingredient labels to stress over,
and it’s almost free! Even better, tap water in most areas of Australia
contains fluoride, one of the easiest and most beneficial ways to help
prevent tooth decay. Making water your beverage of choice and
regularly sipping it throughout the day, including with and right after
meals, makes a real difference to the health of your teeth.
Watch what you eat
It is not just the obvious sweet foods and drinks such as lollies and soft
drinks that can cause decay. Frequent snacking on foods with hidden
sugars like biscuits, crackers, cereals, chips and even dried fruit (these also
break down into sugars in the mouth) can cause acid attacks on your tooth
Here are two teeth friendly habits you can adopt to reduce your risk of
• Have three regular meal times a day, rather than snacking and grazing.
• Limit your sugary treats to be part of a meal, rather than as a snack.
Limit snacking between meals
A key component in helping to prevent decay is saliva which helps your teeth recover from these attacks by neutralising the acids. Its good work, however, can be undone if you snack frequently between meals, which means your teeth don’t get a break from the acid attacks that occur when you eat. Also, limit sugary treats to meal times, rather than between meals.
Chewing sugar-free gum (and that’s the crucial qualifier, it must be
sugar-free!) may not be the first thing that springs to mind when you’re
thinking about good dietary habits to benefit your teeth. Studies have
shown that chewing sugar-free gum for 20 minutes after eating can
prompt your mouth to produce more saliva, which helps neutralise
decay-causing acid attacks.
WHAT YOU CAN DO TO MAINTAIN HEALTHY TEETH:
1. Limit sugary treats to meal times, rather than between meals.
2. Drink fluoridated tap water throughout the day and after meals.
3. Chew sugar-free gum after eating.
Before you make any dietary changes, particularly if you have
any ongoing medical conditions, it’s best to first check with a
