Why Does Red Wine Stain Teeth?

Why Does Red Wine Stain Teeth?

And what can our Essex based cosmetic dentist do to correct the problem?

Among the more commonly mentioned teeth staining foods or drinks is red wine.

Whilst smoking is, perhaps, the worst thing that you can do for your teeth, both from a health and discolouration point of view; the dark ruby red colours of red wine can also take a toll on their appearance.


Why is red wine so responsible for tooth staining? There are actually three factors that contribute to red wine stains:

Firstly, and perhaps least surprisingly is the richness of the red colour itself. This on its own though should cause, perhaps, no more staining than other dark coloured drinks.

One of the problems that red wine has that many other dark coloured drinks don’t is that it is quite acidic. This leads to microscopic markings on the enamel of the teeth. This new ‘etched’ surface makes it much easier for the dark wine ‘molecules’ to attach to. In fact, white wine will also have this effect, but the results, whilst still there, are not as visible as is the case with the darker red wines.

The final factor is that red wine contains tannin which is an astringent and also has high bonding properties. Tannin, one of the major staining agents, and the combination of the other factors is why red wine is responsible for much teeth staining.


Apart from avoiding red wine, of course, there are a few other things which can help to ease the problem.

●  Eating cheese with your red wine can help to prevent the tannin from bonding to the teeth

●  Chewing gum afterwards helps to increase saliva flow which helps to ‘wash’ the teeth

● Cleaning your teeth as soon as possible afterwards will help to minimise any staining.


Of course, if you have been drinking red wine for a long period of time, eventually, your teeth are likely to become discoloured, and no amount of brushing will help when it reaches this stage.

To restore wine stained teeth to a whiteness that you will not have seen for many years, a fast acting teeth whitening procedure is now available at Blue Sky Dental. This procedure can be done in a single visit, taking approximately one hour and we are confident that you will be highly satisfied with the end result.
