What Causes Teeth Discolouration & How to Treat It?

Most of us, looking in the mirror, would love to have whiter teeth and a brighter smile. Did you know as you get older, your teeth will naturally discolour over time?

One of the main reasons this happens is your teeth’s dentin layer becomes more yellow, and the outer enamel layer becomes thinner, revealing the dentin below. This natural discolouration can be made more prominent by certain life choices, like the consumption of certain foods, drinks, and smoking.

There could be a number of other reasons that cause discolouration, so it’s important to know how to limit these potential causes when you're looking to improve and maintain a pearly white smile.

Foods & Drinks that Cause Discolouration


This one won’t come as any surprise, it’s been well documented that soda isn't great for your teeth. Though it’s probably best to leave the soda on the supermarket shelf, if you must have it, try to drink it in moderation to limit it's acidic effect on your teeth enamel.


Whilst berries are great for delivering your body antioxidants, they contain carotenoid, the pigment that gives them their colour. Unfortunately, this pigment can also stain your teeth.

Dark Sauces

Yes, they taste great but their pigmentation can stay on your teeth for hours after you’ve finished your dinner. Soy sauce and balsamic vinegar in particular have very dark pigmentations that can lead to teeth staining, so keep that in mind when you consume these delish sauces.

Now that we’ve looked at some of the causes above, it’s time to let you in on our best tips to slow down the natural discoloration process.

Brush and Floss Your Teeth Daily

We know you already knew this one, but you’d be surprised at how many people still don’t follow the cardinal rule when it comes to keeping your dental hygiene at an appropriate level.

Make sure that you’re brushing your teeth after you wake, and before you sleep for roughly two minutes. Also, don’t forget to floss away the food and plaque that your brush can’t get to.

Eat Foods that Strengthen Your Enamel

There are several healthy foods that you can consume as part of your diet that will prevent and combat your unsightly stains.

Most know that dairy products are a great source of calcium, which is essential for healthy teeth and bones. But they also contain casein, a protein that can help repair and stabilize teeth enamel.

This includes food such as yogurt, cow’s milk, and cream cheese.
