The effects of acid erosion can lead to a general wearing away of the tooth's surface and edges, which can make the teeth look older (for example, yellowing, rounding and cracking of the teeth in later stages). There are many factors which contribute to the progression of acid erosion, most notably the frequency and concentration of the acids in contact with the teeth and the volume and defence of an individual's saliva.

The wear caused by acid erosion can lead to reduced thickness of enamel and a change in texture, shape and appearance of teeth, which may also cause teeth to become sensitive.

Sensodyne Pronamel has been specifically formulated to help protect teeth from the effects of acid erosion. It works in a number of ways: It is specially formulated for people with sensitive teeth – which can be a sign and a symptom of acid erosion

When tooth enamel (the tooth’s hard surface) is exposed to acids (from food, drinks or the stomach e.g. due to sickness or regurgitation), it temporarily softens and loses some of its mineral content. Saliva will help neutralise acidity, restore the mouth’s natural balance and slowly re-harden the tooth enamel. However, because the tooth’s recovery process is slow, if the acid attack happens frequently, the tooth does not have a chance to repair.

Plaque is a colorless, sticky film of bacteria that constantly forms on teeth. If left undisturbed, it hardens to form tartar. The bacteria in the plaque produce byproducts that can not only irritate the gums and make them bleed, but it can also lead to periodontal disease. A daily regimen of proper brushing, flossing and rinsing (plus, regular dental visits), will help you keep your teeth healthy.

Milk teeth are very much at risk from acid erosion because they are less mineralised and therefore the enamel is softer than adult teeth to begin with. Therefore great care should be taken with the acidic content of a child’s diet.

To help protect your teeth against the effects of dietary acids, there are several steps that can be taken: Avoid brushing teeth immediately after consuming acidic food or drinks as this is when the enamel is at its softest. It is best to brush teeth before meals or wait at least 1 hour after eating before brushing teeth Drink acidic drinks quickly – don’t swish them around or hold them for prolonged periods within your mouth.

In the 20th Century, dental diseases, for example tooth decay and gum disease, were widespread. This greatly affected the life span of teeth and meant that the majority did not retain their teeth for life. Improved oral hygiene and restorative treatments have extended the life span of teeth in the 21st Century. However, as teeth are lasting longer they are subject to the effects of wear, particularly from acids and tooth brushing for prolonged time periods.

Your diet during the nine months of pregnancy directly impacts the development of your baby -- including teeth. Because your baby's teeth begin to develop during the second trimester of pregnancy, it is important that you receive recommended amounts of calcium, protein, phosphorous, and vitamins A, C, and D. Consult your physician and dentist for information about proper diet nutrient levels during your pregnancy. [TOP]

AquaDam? is flexible and conforms to the ground and surrounding area to provide an effective seal. Even if the ground is eroded away after installation, the AquaDam? will fill the gaps to maintain the seal. The AquaDam? itself is not susceptible to erosion and does not use fill materials that can be washed out. By eliminating the use of fill materials, AquaDams? also meet the demands of EPA guidelines and Clean Water Act laws that prohibit fill discharge.

The chemical reactions that sulfur dioxide and nitrogen oxides undergo in the atmosphere lead to the formation of particles that can reduce the distance we see and the clarity of our scenic vistas These particles account for over 50 percent of the visibility problems in the the eastern United States. In the West, such particles also have been blamed for visibility problems in the Grand Canyon and other national parks.

GlaxoSmithKline Consumer Healthcare is committed to improving oral health and well-being through unique and successful industry-professional partnerships, working with dental professionals in the front line of care in dental practice; with dental scientists in creating greater understanding of oral care needs and to develop new products; and with dental educators in developing the practitioners and leaders of tomorrow.

Diet, and the way that acidic food and drinks are consumed, is the most likely cause of acid erosion. However it can also result from stomach acids in the mouth, for example, as a consequence of bulimia (vomiting) or indigestion (regurgitation / gastric reflux). There are also instances - as a result of occupational or industrial exposure - where acid erosion has been brought about, for example, by prolonged inhalation of acidic fumes.

tooth enamel is worn away, the underlying dentine may be exposed. This is a softer part of the tooth and as it becomes exposed, teeth may be more sensitive. As nerve endings in the teeth are activated, a slight twinge can be felt when consuming hot, cold or sweet foods and drinks.

Experts agree that nearly everybody with natural teeth will develop some signs of acid erosion. Many will show the mild, early signs of acid erosion, however increasingly significant numbers of people are showing advanced signs. In October 2005, 91% of UK dentists reported seeing cases of acid erosion on a weekly basis.1 The number of people showing signs of acid erosion is rising due to the number of people keeping their natural teeth for longer, combined with the acidity in the modern diet.
