    Tooth decay
    Bangkok Hospital Sanamchan
    Updated on: 18 Jul 2025

    Tooth decay is a disease that should not be underestimated because if not treated promptly, it may eventually lead to tooth loss.

    Causes of the Disease

    It is caused by bacteria commonly found in the mouth that break down starchy and sugary foods, producing acid, which damages the tooth structure. If left untreated, it will worsen, causing the teeth to break, form holes, and if it worsens further, it can cause pain or tooth abscess and may ultimately require tooth extraction.

    Severity

    • Tooth decay will spread from the enamel to the dentin. If it has not reached the dental pulp, it can be treated by removing the decayed part and filling the tooth to restore the damaged area.
    • Untreated tooth decay will continue to spread to the dental pulp, causing inflammation at the tooth root, which requires root canal treatment or extraction.

    Symptoms of Tooth Decay

    • Early stage decay appears as a cloudy white or brown color with a rough surface.
    • As it progresses, it begins to break into decayed holes.
    • Advanced tooth decay results in greater tooth structure loss, making treatment more complex and costly.

    Diagnosis

    In addition to visual and tool examination, another recommended standard method is taking X-ray images, as it can detect tooth decay in areas that are not visible and also indicate the depth of the decay progression.

    Treatment of Tooth Decay

    Treatment starts by removing the decayed part and then filling or restoring the damaged area with various types of filling materials such as amalgam, resin composite, gold, or ceramic. However, if the decay has led to significant tooth loss, a crown may be necessary, or if it has penetrated the dental pulp, root canal treatment is required.

    • Amalgam fillings are strong and durable.
    • Resin composite fillings are aesthetically pleasing.
