Erosion, Attrition, Abrasion

 

Erosion occurs when teeth become damaged by acids. So it is prudent to reduce the time our teeth are in contact with acids.· The source of the acid may be intrinsic (stomach acid reflux, vomiting, burping) or extrinsic (diet, drinks, environmental, occupational)· After your teeth have been exposed to acids, do not brush your teeth for two hours. It takes time for your saliva to neutralise the acidic pH. E.g. Brushing your teeth straight after vomiting when your teeth have been soaked in acid can accelerate tooth damage· Tap water containing fluoride is the best drink. Many other drinks are acidic, such as juices, sports drinks, soft drinks. If you consume these it is best to follow with water

 

Attrition is the damage of tooth surface caused by tooth to tooth grinding and clenching. As teeth are rubbed against each other, you wear down your teeth. Similar to when you rub two stones together, powder is formed and the stone is worn. So it is important that your do not grind or clench your teeth unnecessarily. Some persons grind their teeth when sleeping or stressed, these persons should use an occlusal spint (similar to a mouth guard) to protect their teeth.

 

Abrasion is when the tooth surface is damaged by a foreign object, usually a tooth brush. It is recommended you use soft or extra soft toothbrushes. Many people use Medium bristle toothbrushes because they polish the teeth and make the teeth feel smoother and cleaner. Long term this does damage to your teeth, and in many persons who brush aggressively damage is visible on the sides of the teeth. Usually right side of the upper right teeth, on right handed individuals.
