food cause erosion? Do you believe??
Acidic food and drinks can cause erosion the gradual dissolving of the tooth enamel. The lower the pH number, the more acidic the product. Anything with a pH value lower than 5.5 may cause erosion. ‘Alkalis’ have a high pH number and cancel out the acid effects of sugars. pH 7 is the middle figure between acid and alkali.
mineral water (still) pH 7.6, milk pH 6.9, cheddar cheese pH 5.9, lager pH 4.4, orange juice pH 3.8, grapefruit pH 3.3, pickles pH 3.2, cola pH 2.5, red wine pH 2.5, Vinegar pH 2.0
It is better for your teeth and general health if you eat 3 meals a day instead of having 7 to 10 snacks. If you do need to snack between meals, choose foods that do not contain sugar. Fruit does contain acids, which can erode your teeth. However, this is only damaging to your teeth if you eat an unusually large amount. Try not to have a lot of dried fruit as it is high in sugar and can stick to your teeth.
If you do eat fruit as a snack, try to eat something alkaline such as cheese afterwards. Savoury snacks are better, such as: cheese, raw vegetables, nut, breadsticks.
The main point to remember is that it is not the amount of sugar you eat or drink, but how often you do it. Sweet foods are allowed, but it is important just to have them at mealtimes.
To help reduce tooth decay, cut down on how often you have sugary foods and drinks and try to have sugar-free varieties. Confectionery and chewing gum containing the artificial sweetener Xylitol may help to reduce tooth decay. Sugary foods can also cause a range of health problems including heart disease and being overweight.
