What does early tooth decay look like?

Early tooth decay is usually the first stage of tooth decay, when enamel demineralisation occurs but no visible holes or cavities are yet apparent.

Signs of early tooth decay may include:

• White spots on teeth: One of the first signs of early decay is whitish, dull spots on the enamel, which indicate demineralisation (loss of minerals). This condition may be reversible if teeth are cared for properly, for example through regular fluoridation.
• Sensitivity: Teeth may be sensitive to cold, hot or sweet foods and drinks. This sensitivity occurs when the tooth enamel begins to weaken and exposes the more sensitive layer underneath (dentine).
• Light dental plaque or discolouration: A fine plaque or discolouration may appear on the surface of the tooth, which may be caused by the accumulation of bacteria that produce acids and damage the enamel.

If early tooth decay is not detected and treated in time, it can progress and lead to deeper decay, which would require more complex and costly treatment, such as a filling or other procedure. That is why it is important to have regular check-ups at the dentist.
