As a first line of defence, stop doing things that could be leading to enamel erosion. For instance, stop eating acidic foods. Replace your toothbrush if it has hard bristles. Brush your teeth only after 30 minutes of eating.
If the enamel erosion is extensive (maybe you’re experiencing severe tooth sensitivity), visit a dentist. Often, they may recommend dental bonding or veneers. In any case, connect with the best dentist in Kolkata and seek timely treatment for enamel erosion before the condition worsens.
