Enamel erosion explained: acidic foods, drinks and tooth sensitivity
dentalhealth
Enamel wear can quietly lead to sensitive teeth. Learn how acid wears it down and the everyday habits that help protect it.
Enamel is the hard outer layer that shields your teeth. When it thins, the dentin beneath can react to cold, heat and sweets. Here's a closer look at how erosion happens and what helps.
How acid affects enamel
Foods and drinks with acid can temporarily soften enamel. Over months and years, repeated exposure can wear it down. Stomach acid from reflux can have a similar effect.
Everyday sources of acid
- Soda and sparkling water with added flavours
- Sports and energy drinks
- Citrus fruit and juices
- Wine
- Frequent sipping through the day
Signs enamel may be thinning
- Sensitivity to cold or sweets
- Teeth that look slightly yellow as dentin shows through
- Edges that look rounded or translucent
- Small dents on chewing surfaces
Habits that help protect enamel
- Enjoy acidic drinks with meals rather than sipping all day
- Rinse with water afterward
- Wait about 30 minutes before brushing
- Use a fluoride, sensitivity-friendly toothpaste
- Brush gently with a soft brush
What your dentist can do
An exam can show how much wear is present and what's causing it. Options may include protective products, bonding to cover worn areas, or advice on reflux or grinding. See our dental treatments for more, or read the main post on why teeth are sensitive to cold.
