Help protect your teeth against the growing problem of acid wear. Dentist have reported a growing dental health concern due to changing modern diets: 'acid wear'. Even teeth without cavities can be affected. Acids in everyday food such as some fruit and acidic drinks like orange juice and wine can dissolve minerals from our teeth, softening the enamel surface which is then more easily worn away. As the enamel becomes thinner, teeth can become visibly less white, weaker and sensitive.
