Understanding and preventing acid erosion of teeth
Tooth erosion is the permanent loss of the outer enamel layer of your teeth. Unlike tooth decay, which is caused by plaque bacteria, erosion occurs when enamel is dissolved by a chemical reaction with acids. Once enamel has been dissolved, the inner softer dentine is exposed and dissolves at a much quicker rate.
As enamel wears away, teeth may appear yellower because the underlying dentine shows through. Teeth can look shiny with rounded edges, and front teeth may appear see-through with transparent edges. Biting edges can become chipped and uneven, small hollowed out pits may appear on the surface (often on the back molars), and fillings may appear higher than the surrounding tooth.
As the enamel thins, teeth become increasingly sensitive to hot and cold temperatures. This is usually a short, sharp pain lasting just a few seconds.
The most common cause of tooth erosion is dietary acids. Fizzy drinks, carbonated water, lemon water, fruit juices, smoothies, alcohol, citrus foods, and vinegar-based salads all contain acids that dissolve tooth enamel over time.
Stomach acid is another significant cause. Gastric reflux, frequent vomiting, and eating disorders can all expose teeth to strong stomach acids, leading to erosion of the enamel.
Once enamel has been lost, it cannot grow back. However, fluoride treatments can help to strengthen the remaining enamel. Dental Composite Bonding is a modern, conservative technique that can repair uneven surfaces without drilling. For severely damaged teeth, veneers or crowns may be necessary, although these are more costly and require drilling of the tooth.
Tooth decay is caused by sugary bacteria, while erosion is entirely acid-driven. Diet fizzy drinks may have no sugar but are still acidic — they are less likely to cause decay but will still damage teeth by erosion. Understanding this distinction is important because it means that even sugar-free drinks can harm your teeth.
