How To Whiten Yellow Teeth At Home (And Keep Them That Way)

Last Updated: 28th September 2016

Stained and dull yellow teeth are not what you want to see when you look in the mirror. You want a pearly white smile, right?

Sadly, instead of the spotless smile,you wish for, your teeth are becoming yellow and stained.

Yellow teeth can make you feel less confident and embarrassed when you talk to others – let alone smile.

I know I didn’t want to smile after months of drinking tea left my teeth embarrassingly yellow and stained.

However, I don’t want to restrict my tea or coffee, and I bet you don’t, either.

You want to have stain-free white teeth without sacrificing drinks you love, but you don’t want to pay for a professional cleaning every time or buy painful over-the-counter products.

Fortunately, you don’t have to.

You can whiten your teeth at home safelyand painlessly. I’ll show you how.

First, let’s look at what can be causing your yellow teeth:

Why Your Teeth Are Getting Yellow

    Acidic foods can eat away your tooth enamel and reveal the dentin, the layer below the enamel, which is yellow and can’t be whitened.

    Again, coffee, wine, and black tea are acidic, but so are sodas, soft drinks energy drinks, sports drinks, soy sauce, pickles, alcohol, lemon juice and vinegar. Soft drinks have been shown to cause severe tooth enamel erosion and caries.

  • Foods with colorants: The food colorants from processed foods such as hard candy, gummies, popsicles, breakfast cereals, and cake icing will attach to your enamel and stain your teeth.
  • As a rule of thumb, if what you eat stains your tongue, it can stain your teeth as well.


  • Smoking: Tobacco wreaks havoc in your oral health, including severe staining and tooth abrasion.
  • Cigarettes

    The nicotine in tobacco is responsible for the staining of your teeth because it turns yellow when it mixes with oxygen.

  • Poor hygiene: The American Dental Association recommends brushing your teeth, at least, two times per day and floss at least once a day. Not brushing regularly will lead to plaque accumulation, which is formed by bacteria, saliva, and food particles.2
    Oral Care

    Plaque can make your teeth look yellow, erode enamel, and cause cavities and gum disease.

    If you don’t brush your teeth for several days, the plaque can stiffen and turn into a more harmful substance called tartar, a yellow layer of hardened plaque that can erode your teeth even further.

  • Brushing too soon after meals: Brushing your teeth right after eating sounds like a good way to keep bacteria off your mouth, but it has been shown to erode tooth enamel.
  • Oral Care

    Here’s why: Whenever you eat, the acidity of the meal leaves your tooth enamel weakened and softened for a short period, and brushing in that moment can remove some of it. This is dangerous because enamel doesn’t grow back.

    It’s recommended to wait at least 30 min after finishing a meal before brushing your teeth.

    Also, the sensitivity of your enamel will be higher if you eat highly acidic foods such as soda, coffee, or soft drinks.

Fortunately, there are simple habits you can follow on a regular basis to keep your teeth clean, white, and stain-free. Let’s take a look:

Smart Habits To Prevent Yellow Teeth

1.Rinse your mouth after drinking dark-colored beverages

Iced Water

A great way to prevent drinks like wine, coffee, and tea from staining your teeth is to rinse your mouth with water or drink a glass of water afterward.

This way the pigments won’t sit on your teeth, and you’ll lower acidity as well.

Think of your teeth like a white tea mug. The leftover pigment you can see in the mug is also on your teeth, so rinse as soon as you can. Remember not to brush right after drinking because the enamel is sensitive like I mentioned above.

2.Eat crunchy foods that cleanse your mouth naturally

Crunchy Green Apples

Naturally crispy fruits and vegetables like apples, pears, carrots, celery, guava, and broccoli help remove food particles and plaque from your mouth. The fibrous texture does a great job at cleansing and gently scrubbing your teeth.

There’s a reason apples are often referred as “nature’s toothbrush”. Chewing apples have been shown to remove food debris, and other crunchy foods have a similar effect.

3. Clean your teeth more often

Oral Care

To prevent plaque from staining your teeth, you need to brush at least twice a day and floss once a day, according to the American Dental Association.

Flossing is extremely important to keep plaque off those hard to reach spaces between your teeth. Even if you brush regularly, lack of flossing can cause plaque to accumulate on the sides of your teeth and generate cavities and inflammation that can lead to gingivitis.

So how should you floss?

Well, some experts claim it doesn’t matter whether you floss before or after brushing, but a recent study concluded that flossing before brushing is more effective at reducing plaque than flossing after brushing.

The right way to floss is to hug the floss to the side of the tooth and scrape down away from the base.

4. Eat calcium and phosphorus-rich foods

Green Cruciferous Vegetables

What high acidity foods do your teeth is called demineralization. This happens when certain foods lower the natural PH levels in your mouth, which allows plaque bacteria to soften and erode enamel.

Saliva, which is saturated with calcium and phosphate, is in charge of remineralizing your teeth, a process that hardens tooth enamel strengthens teeth, and neutralizes acidity. A diet rich in bone-healthy minerals such as calcium and phosphorus will ensure your saliva can do its job.

Foods high in calcium and phosphorus include bone broth, broccoli, kale, tofu, sardines, sesame seeds, yogurt, spinach, sunflower seeds, salmon, and Brazil nuts.

Now that you know how to take care of your mouth daily to prevent yellow teeth let’s look at effective remedies that will get rid of stains and give you the pearly white smile you seek.
