Acidity of the modern diet coupled with popular consumption habits is causing increasing concern among dentists, who say the problem can lead to acid erosion which can cause considerable long-term consequences for the health and appearance of teeth.

Many everyday foods and drinks are acidic including many fruits, fruit juices and fruit teas, sauces and dressing. When consumed, the acids temporarily soften the tooth’s hard enamel surface. Over time, this acidic softening can lead to significant wear, resulting in the enamel becoming thinner.

The thinned enamel can lead teeth to become sensitive to hot, cold or sweet food, which may be the first sign of acid erosion. In the long term, acid erosion can also change the appearance of teeth, such as showing up as a darker yellow appearance, as transparency near their biting edges or as small cracks on the edges of teeth. The effects of acid erosion cannot be reversed – so protection is the best policy.

To help combat acid erosion, Sensodyne has launched a fresh new addition to the Sensodyne Pronamel range – Sensodyne Pronamel daily mouthwash. Used with the Sensodyne Pronamel toothpaste, it offers superior protection against the effects of acid erosion.

Monica Abdilla, country manager consumer healthcare for GlaxoSmithKline, manufacturers of Sensodyne, said: “It is important for people to recognise that some everyday foods are highly acidic which can lead to permanent damage to teeth. Some of these items such as fruit and fruit juices are an important part of a healthy, balanced daily diet so we would never recommend cutting these food groups from your diet. Instead, simple changes to your daily routine can help to protect teeth from the acids in our diet.”

Tips to help protect teeth from acid erosion

• When having an acidic drink, use a straw angled towards the back of the mouth to help keep teeth protected.

• Drink water after eating or drinking anything acidic to help wash the acid away, or chew gum to stimulate the production of saliva which can neutralise the acid.

• After an acidic meal, consider eating some enamel friendly foods like low fat cheese or nuts, to help restore the pH balance in your mouth.

• After consuming acidic food or drinks, wait at least an hour before brushing your teeth – because this is when enamel is at its softest, and so most at risk.

• Visit your dentist regularly – only a dental professional can diagnose acid erosion.
