Yellow or discoloured teeth are a common cosmetic concern. Some people notice gradual changes over time, while others feel their teeth look darker than expected despite good oral care.

Monitoring involves noticing whether colour continues to change.
It’s sensible to book a dental visit if:
Discolouration affects confidence
One tooth looks darker than others
Colour change appeared suddenly

Identify external vs internal staining
Check for decay or trauma
Discuss cosmetic and clinical options
Tooth discolouration is common and often manageable.
Understanding the cause helps guide safe and effective treatment choices.
