ISO-Snacking… what will stain your teeth during these times of increased snacking!

Let’s be honest, isolation can be boring, so it’s only natural that we eat more to keep ourselves occupied! So, here are some common culprits that can cause tooth staining. Generally speaking, anything dark in colour can stain your teeth over time! There are two types of tooth staining: intrinsic and extrinsic tooth stains. Intrinsic stains come from the ‘inside’ of the tooth, underneath the enamel. Extrinsic stains sit on top of the enamel.


Foods/drinks that can cause extrinsic tooth staining:


  1. Red wine
  2. Dark/strong herbal teas (In my experience particularly dandelion tea and green tea can be big offenders when consumed regularly)
  3. Regular tea
  4. Coffee – Particularly black coffee
  5. Curries
  6. Berries – such as blueberries and blackberries
  7. Beetroot
  8. Cola drinks – these also can cause tooth erosion due to their low (acidic) pH
  9. Dark coloured fruit juices (blackcurrant, blueberry, grape etc)

In general, the majority of the time, extrinisic stains can be removed! (Yippee – you can still enjoy your favourite daily grind of coffee and a tasty curry to warm those winter nights!).

Extrinsic tooth stains can be removed by visiting us 6 monthly for your regular scale and clean appointments. You can also help to reduce the build-up of stains by brushing twice a day with an electric tooth brush and using a straw whilst drinking juice and cola drinks. Rinsing your mouth out with water after consuming any of the above can also help.
