How Lifestyle Habits Affect the Colour of Your Teeth

It’s no secret that we all want a bright, confident smile. But over time, you might start to notice your teeth looking a little dull or discoloured. That’s because many of our everyday habits, from the foods we eat to our lifestyle choices, can slowly change the colour of our teeth.

At West London Orthodontics, we specialise in teeth whitening treatments that reverse the effects of staining and restore your smile’s brightness. But first, let’s take a look at what might be causing your teeth to lose their shine.

1. Diet and Food Choices

Your diet plays a significant role in tooth discolouration. Drinks like coffee, tea, red wine, and fizzy drinks are known for their staining power. Dark-coloured berries, soy sauce, and tomato-based sauces can also gradually affect the brightness of your teeth.

While it’s not necessary to give up these favourites, enjoying them in moderation and rinsing your mouth with water afterwards can help minimise staining.

2. Smoking and Tobacco Use

Tobacco products are one of the most common causes of yellow or brown-stained teeth. Smoking doesn’t just discolour your enamel, it also affects your gums and overall oral health. Patients who quit smoking often see an improvement in the appearance of their teeth as well as their breath and gum condition.

3. Poor Oral Hygiene

Brushing and flossing daily is key to preventing plaque build-up, which can trap stains and make your teeth appear dull. Regular hygiene appointments with your dentist in Hammersmith are also essential to maintain the best appearance of your teeth.

4. Ageing

As we age, the enamel on our teeth naturally wears down, revealing the yellow-toned dentin underneath. While this is a normal process, it can make your teeth look darker than they used to. Luckily, dental teeth whitening can help restore a more radiant smile.

5. Certain Medications

Some antibiotics and high blood pressure medications can cause tooth discolouration as a side effect. If you’re concerned about how your medication may be affecting your teeth, speak to your GP or teeth whitening dentist for advice on your options.
