Enamel erosion: the silent damage you might not notice
Enamel doesn't grow back. Understanding erosion is the first step to protecting what you have.
Dental enamel is the hardest substance in the human body, but it can't repair itself. Once eroded, it's gone. The good news is that erosion is largely preventable.
What causes erosion
- Acidic drinks: fizzy drinks, fruit juices, energy drinks, sports drinks
- Frequent consumption of citrus fruits
- Gastro-oesophageal reflux (GORD), where stomach acid reaches the mouth
- Excessive vomiting (including eating disorders)
- Some medications (effervescent tablets, vitamin C supplements)
Signs of erosion
- Teeth appear yellower (the dentine beneath shows through as enamel thins)
- Rounded, smooth-looking teeth (edges become less sharp)
- Increased sensitivity
- Small dents or indentations in tooth surfaces
How to protect your enamel
- Reduce acidic drink frequency (not necessarily quantity)
- Use a straw for acidic drinks to reduce contact with teeth
- Rinse with water after acidic food or drinks
- Wait 30 minutes before brushing after anything acidic
- Use a fluoride toothpaste and mouthwash to remineralise
- Discuss GORD with your GP if relevant
