IT would be ideal if teeth could be and stay white for a lifetime.

But in reality, there are a number of things that can cause your teeth to become discolored, with yellow being the most familiar color.

Are your teeth white? If not, Chief Orthodontist at Impress, Dr Khaled Kasem reveals why

Identifying the cause of discoloration could help you to improve the shade of your smile.

But it could also give an indications of your health;

Here, chief orthodontist at Impress, Dr Khaled Kasem, reveals the difference between teeth colors.

1. Yellow

Teeth naturally become more yellow with age, because the white enamel on the surface of the teeth is worn down over time, exposing the yellow core beneath.

But it's also as a result of what we eat and our attention too oral care.

Dr Khaled said: “Yellow is the most common color for stained teeth. 

“Yellow stains will often mean you’re consuming large amounts of dark-colored food and drinks, such as coffee, tea, soy sauce and curry.

“It can also be an indication that you’re not paying enough attention to your oral health care routine, and need to make sure you’re flossing, brushing and attending regular dental health care check-ups.”

The standard rule for teeth brushing is twice per day for two minutes.

2. Purple

If your teeth are purple it’s usually just because you have been drinking red wine.

But Dr Khaled said: “Not only can purple stains on the teeth indicate a sign of a good night, but it could also mean you’re consuming too many dark-color fruits, such as pomegranates or berries. 

“However, it’s important to not dismiss purple stains completely, as it could also be a sign of internal bleeding caused from dental trauma. 

“If you're not sure where the stains have come from then it’s best to check with your dentist.”

‘Dental trauma’ can include falls, car crashes or sports-related injuries.

3. Grey

When teeth go grey, it could be because the blood supply to the tooth has been cut off. 

This can happen over a long period of time.

Dr Khaled said: “If you’ve developed grey stains or spots on your teeth, then you must visit your local dentist for a thorough examination. 

“This is because grey spots or stains can often be an indicator of nerve damage caused by dental trauma. 

“Seeking dental advice will properly address the issue and make a plan to restore the appearance of the teeth.”

Materials used to fill cavities may also turn grey, and ageing can also grey the teeth.

4. Black 

Any indication of black in your teeth should be investigated because it suggests “high levels of decay”, said Dr Khaled.

“This discolor, unfortunately, means your teeth are in an advanced stage of deterioration,” he added.

“If you ignore this, then it could lead to more serious dental health conditions, ultimately leading to tooth loss.”

Other signs of tooth decay include toothache, sensitivity and gum infection.

When tooth decay is spotted early, through regular dentist trips, you can usually reverse it or get a filling in holes.

But if the decay is severe, you may need root canal treatment or have the tooth removed.

How to avoid teeth staining

Having good oral care can lessen the likelihood of staining. 

Dr Khaled said you could also limit your consumption of teeth-staining foods and drinks.

And stop smoking, as this accelerates staining among causes dozens of other health conditions, including mouth cancer.
