WHAT CAUSES YELLOW TEETH?
Extrinsic stains are more commonly known stains caused by certain foods, drinks, or smoking. They can cause staining because teeth have a porous surface.
“We eat and drink staining compounds every day and this is the reason why regular brushing is so imperative.
Foods and drinks that can cause teeth to yellow and stain include:
• coffee
• red wine
• sodas and energy drinks with added colors
• darkly pigmented fruits
• acidic sauces and condiments
Staining can also occurs from the dentin (inner layer) of teeth. The dentin darkens and it’s hard to change the color.Sstains can be yellow or brown, but they can also be gray or white. This kind of staining (extrinsic stains) can occur from injury, medications, and thinning of the enamel from age.
CAN WE FIX IT?
Extrinsic stains can be removed by a chemical reaction with peroxide that breaks the bonds of the chromogen, rendering them colorless.
However, intrinsic stains are much harder to change and usually need porcelain veneers, crowns, or bonding.
There are natural ways to whiten teeth (lemon juice,charcoal, baking soda). But dental hygienists say that they come with harmful effects on your tooth’s natural structure. For that reason, you’re probably better off passing on them.
Tips to achieve your brightest, whitest smile yet without risking tooth sensitivity or damage:
– Drink dark liquids through a straw
– Rinse your mouth with water after consuming staining foods
– Eat strategically. Fo example, try eating a salad or dark greens (like kale or spinach) before drinking or eating a staining food.
This will help create a film over the teeth to lessen stain penetration. Similarly, some food can also help by acting like a natural toothbrush (apples, pears, celery, carrots, cauliflower, cucumbers).
– Be careful with harsh “whitening” toothpastes loaded with harsh abrasives.
– Invest in an electronic toothbrush
– Follow a solid dental hygiene routine
