Tooth wear
Tooth wear refers to the loss of the hard, outer layer of the tooth, known as the enamel. This can occur as a result of several factors, including abrasion, attrition, erosion, and abfraction. Tooth wear can lead to a variety of dental problems, including sensitivity, pain, and tooth loss.
Causes[edit | edit source]
Tooth wear can be caused by a variety of factors. These include:
- Abrasion: This is the process of wear caused by something rubbing against the teeth. The most common cause of abrasion is brushing the teeth too hard or using a hard-bristled toothbrush. Other causes can include habits such as nail-biting or pen-chewing.
- Attrition: This is wear caused by the teeth rubbing against each other. This can occur as a result of grinding or clenching the teeth, a condition known as bruxism.
- Erosion: This is wear caused by acid attacking the teeth. This can occur as a result of consuming acidic foods and drinks, or from stomach acid in people with conditions such as gastroesophageal reflux disease (GERD).
- Abfraction: This is a type of tooth wear that occurs near the gum line. It is believed to be caused by stress on the tooth, such as from biting or chewing.
Symptoms[edit | edit source]
The symptoms of tooth wear can vary depending on the cause and severity of the wear. They can include:
- Sensitivity to hot, cold, or sweet foods and drinks
- Pain or discomfort when chewing or biting
- Changes in the appearance of the teeth, such as discoloration or changes in shape
- Tooth loss
Treatment[edit | edit source]
The treatment for tooth wear depends on the cause and severity of the wear. It can include:
- Changing brushing habits or using a softer toothbrush to reduce abrasion
- Wearing a mouth guard at night to reduce attrition from bruxism
- Avoiding acidic foods and drinks or treating underlying medical conditions to reduce erosion
- Dental procedures such as bonding, crowns, or veneers to repair worn teeth
Prevention[edit | edit source]
Preventing tooth wear involves addressing the underlying causes of the wear. This can include:
- Using a soft-bristled toothbrush and not brushing too hard
- Seeking treatment for bruxism
- Limiting consumption of acidic foods and drinks
- Regular dental check-ups to catch and treat wear early
