Although diet coke has no sugar in it and therefore does not cause tooth decay, all cokes and fizzy drinks contain carbonic acid which means you are essentially bathing your teeth in a weak acid and this destroys the enamel (dental erosion). This causes disfiguring tooth loss, pain and sensitivity. The odd can of coke is not a problem but we know that many people drink up to a litre a day! Not only does the carbonic acid damage your teeth it also damages your bones….so please try and reduce your intake or better still stop completely. Use a straw and never ‘swish’ drinks around your mouth to reduce tooth damage. Alcopops and fruit juices can also be damaging. Water and milk are the best drinks. Sometimes the damage can be repaired using tooth coloured fillings bonded to the teeth or in more severe cases using porcelain veneers. Duraphat toothpaste which contains high levels of fluoride can help prevent further damage.
Diet health tip
The most common cause of tooth decay is refined sugars, which by encouraging plaque build up can also lead to gum disease. Examples of refined sugars include sucrose, glucose, dextrose, corn syrup and glucose syrup. Even natural sugars such as those found in fruit and honey can cause plaque acids. Examples of natural sugars include fructose, lactose and maltose. Acid in plaque builds up only seconds after eating sugars but may take 30 minutes to return to safe levels. It is not only the quantity of sugar that can cause damage but the frequency, so if you do eat sweets, avoid spreading them out over a long period of time.
