-Erosion
-Attrition
-Abrasion
Erosion is the progressive loss of tooth substance by
chemical or acid dissolution, and no bacteria are involved. Erosion of tooth
surfaces is mostly the results of too frequent or inappropriate use of
carbonated drinks (including sparkling water) and fruit juices with high levels
of acidity. This habit would appear to be particularly common amongst teenagers
and young adults.
Attrition is the progressive loss of hard tooth substances caused by mastication or grinding between opposing teeth. The extent of attrition will depend upon the use to which an individual puts their teeth. For example, it will increase in people who habitually clench or grind their teeth (a condition known as bruxism), e.g., during sleep.
Abrasion is the progressive loss of hard tooth substances caused by mechanical actions other than mastication or tooth-to-tooth contacts. Abrasion is commonly associated with incorrect toothbrushing technique, giving rise to notching at the junction of the crown and root of teeth. It will also be seen in individuals who use their teeth as a tool (e.g., to remove bottle tops, to hold pins, clips or nails). The long-term use of tongue jewelry also causes tooth abrasion, when the jewelry is hitting against the teeth.
To prevent tooth wear:
-Limit the amount of carbonated and sugary/acid fruit juices
-Use proper brushing technique as recommended by your dentist
-Be
evaluated for orthodontic treatment to correct an improper bite
In 100 years we hope that tooth wear will no longer be an issue if we educate people now.
