Ever wondered what the colour of your teeth says about your health? Science has uncovered fascinating insights into how different shades can reveal underlying health conditions, lifestyle habits, and even genetic factors.
The Science Behind Tooth Colour
Teeth aren’t naturally pure white—their shade varies based on genetics, diet, and oral care. However, unusual discolouration can signal health issues worth investigating.
Yellow Teeth
While slight yellowing is normal with age, excessive yellowing may indicate:
- Poor oral hygiene leading to plaque buildup
- Frequent consumption of staining foods like coffee, tea, or red wine
- Smoking or tobacco use
- Thinning enamel revealing the yellowish dentin beneath
Grey Teeth
Greyish teeth could point to:
- Tooth trauma causing internal bleeding or nerve damage
- Certain medications like tetracycline antibiotics taken during childhood
- Excessive fluoride exposure during tooth development
White Spots or Streaks
These may suggest:
- Early signs of tooth decay (demineralisation)
- Fluorosis from excessive fluoride intake
- Enamel hypoplasia (underdeveloped enamel)
When to See a Dentist
While some discolouration is harmless, sudden changes or dark stains warrant professional evaluation. Modern dentistry offers solutions like whitening treatments, veneers, or improved oral care routines to restore your smile’s brilliance.
Remember, your teeth are windows to your overall health—don’t ignore what they’re trying to tell you!
