Are your teeth at risk of tooth decay or tooth wear? In this post we explain how tooth surfaces are affected by what we eat and drink and what you can do to help keep your smile in tip top shape.<\/p>

If you follow Growing Smiles on social media you may have noticed the post about Stephan curves. Stephan Curves show what happens to the pH in our mouths when we eat\/drink. The pH in our mouth is important as it can lead to loss of tooth surfaces by a process called demineralisation (dissolving tooth surfaces). Our mouths are in a constant see-saw motion between demineralisation and remineralisation (re-hardening of the surface).<\/p>
Enamel is the outer covering of our teeth and the hardest substance in the body. Dentine is the layer beneath the enamel and makes up the majority of the tooth surrounding the pulp chamber which houses the nerves and blood vessels.<\/p><\/div> When pH drops to 5.5 or below enamel will start to dissolve (demineralise), dentine starts to demineralise around pH6.4. This means exposed dentine e.g. on root surfaces are at increased risk from acid attack. The longer teeth remain in ‘danger zones’ of acid attack where demineralisation occurs, the more damage to teeth. <\/p><\/div><\/div> While there are other causes of tooth surface loss (tooth wear), tooth surfaces demineralise most commonly as a result of tooth decay (dental caries) or acid erosion.<\/p> Bacteria in dental plaque digest dietary sugars (particularly free sugars) to produce acids = pH drop. These acids demineralise the tooth surface and over time the result is a cavity (tooth decay). As the pH rises calcium phosphate ions remineralise the tooth surface. The more time teeth spend in \u2018danger zones\u2019 without enough time between acid attacks for tooth surfaces to remineralise, the more damage will occur.<\/p><\/div><\/div> The difference between tooth surface loss from acid erosion<\/strong> and tooth decay is the presence of bacteria in the plaque biofilm. Erosion occurs without <\/strong>bacterial plaque present. Acids from the stomach or from the diet – e.g. food\/drink, but also medication and supplements (anything with low pH), come in contact with tooth surfaces = demineralisation. Erosion is also affected by titratable acidity. Titratable acidity is the effort required to return pH to a neutral\/safe environment. The higher the titratable acidity the longer it takes for pH to return to neutral.<\/p> A process called remineralisation is the natural repair process for teeth. Think of it as hardening the tooth surface after acid attack.<\/p> Saliva is extremely important in the process of recovering a neutral pH to the mouth by remineralising (hardening) tooth surfaces after acid attack. Calcium and phosphate minerals are depositing back into the tooth surface by saliva. Lack of saliva or saliva that is thick, ropey or sticky increases the risk of developing tooth decay (caries) and\/or erosion.<\/p> Tooth surface either from decay or erosion is a balancing act between how long the teeth are bathed in acid v the time it takes for the teeth to recover and stay in the \u2018safe\u2019 zone.<\/p> Diet <\/strong>\u2013 too much decay causing sugar<\/strong>, too often<\/p>\n\n Lack of fluoride<\/strong> around teeth<\/p>\n\n Lack of saliva<\/strong> and its buffering capacity<\/p><\/div> Non decay related tooth wear<\/strong> is related to various factors. It is important to identify the cause of tooth wear to ensure appropriate management.<\/p><\/div><\/div> Speak to your dentist<\/strong> to find out if high fluoride toothpaste, topical fluoride therapy or fissure sealants are appropriate.<\/p><\/div><\/figure><\/div>
