Did you know that acid erosion is the gradual loss of tooth enamel caused by acids, not bacteria?
Unlike tooth decay, erosion happens when acid directly wears away the surface of the tooth. And once enamel is lost, it doesnât grow back. Thatâs why recognising it early and focusing on prevention is so important.
Acid can come from everyday dietary sources such as fizzy drinks (even sparkling water), energy and sports drinks, wine and vinegar-based foods. It can also be linked to medical factors, including acid reflux, where stomach acid flows back into the mouth, particularly at night.
Frequent vomiting can also affect enamel. This may be seen with pregnancy-related morning sickness, gastrointestinal illness or eating disorders.
Signs to look out for include:
đڎTeeth appearing thinner or more translucent
đڎYellowing as the underlying dentine shows through
đڎIncreased sensitivity
đڎSmall dents on biting surfaces
đڎRoughness or fine cracks
Prevention is always better than repair.
Try to limit acidic foods and drinks and keep them to mealtimes rather than sipping throughout the day, as this reduces repeated âacid attacksâ on the teeth. Where possible, use a straw and rinse with water afterwards.
After consuming something acidic, enamel is temporarily softened. Wait 30-60 minutes before brushing to avoid brushing softened enamel and causing further wear.
Finally, protect your enamel by using a fluoride toothpaste (or hydroxyapatite if you are fluoride-sensitive) to help strengthen and remineralise the tooth surface.
If youâre noticing any of these signs, do book an appointment. Early intervention can make a significant difference, and if needed, your dentist can liaise with your GP where a medical cause is suspected. Give us a call on 020 7221 1680 to book.
We look forward to welcoming you.
