How to Get Rid of Yellow Teeth

If your teeth are yellow because of something you ate or the plaque is building up on your teeth, you’re in luck. You can restore these stains just by taking proper care of your teeth and brushing them. If your teeth seem like they’ve turned yellow though, your white enamel has worn away a little and you’ve exposed the dentin, which is a layer of pulp behind the enamel. This is a normal part of getting older so it doesn’t mean you’ve done anything wrong, but it’s understandable that you’d like to have a whiter smile. While you cannot technically replace enamel once it’s gone, you can protect the existing enamel and help it remineralize to make your teeth look beautiful and white.

Taking Care of Your Teeth

  1. Brush first thing in the morning when you get out of bed, and last thing at night before you go to sleep. Use a small dollop of toothpaste and brush in gentle, smooth circular motions and vertical strokes. Spend at least 2 minutes brushing each time you do it and avoid brushing too hard. This is the best way to protect your teeth’s enamel and keep your mouth healthy and clean. [1]
    • Give your tongue a few brushes or use a tongue scraper to clean your tongue after you’re done with your teeth.
    • Regular toothbrushes are fine, but electric toothbrushes can make it easier to maintain a proper brushing technique. They won’t make your teeth cleaner or anything, but they don’t require as much effort to use correctly. [2]
    • Brushing more than twice a day can actually wear the enamel on your teeth down. Your teeth won’t get cleaner if you brush too hard or too often.
  2. There is no good replacement for fluoridated toothpaste. Fluoride strengthens the enamel naturally and helps remove stains, which is essential if you’re looking for a beautiful, white smile. While some naturalists worry about fluoride’s effect on the body, there’s no evidence that fluoridated toothpaste is dangerous to use. [3]
    • While you can’t replace enamel, fluoride can help strengthen weakened enamel. This will make your teeth whiter, even though you aren’t technically bringing any enamel back. [4]
    • If you have sensitive teeth, feel free to opt for a fluoridated toothpaste designed specifically for sensitive teeth.
    • When it comes to the flavor, style, and texture of the toothpaste, it’s entirely a matter of personal preference. None of these qualities impact the toothpaste’s ability to clean your teeth so long as the toothpaste has fluoride in it.
    • There isn’t much evidence that whitening toothpaste is particularly productive. There’s nothing wrong with using it, but don’t get upset if you don’t see major results. [5]

  3. Pull out a 12–18 in (30–46 cm) length of floss. Wrap the floss around a tooth and slide it back and forth gently while moving it up and down the tooth. Do this for 20-30 seconds and repeat the process with each of your teeth. Floss at least once a day to keep food and plaque from building up in the gaps between your teeth, since food particles and plaque can erode enamel. [6]
    • A lot of people think flossing is optional, but it’s not. Flossing is essential when it comes to protecting your teeth and keeping them shiny and white!
    • If your gums bleed when you floss, it means your gums are inflamed. This is basically a form of gum disease, but it may go away on its own with regular flossing and brushing. If you keep bleeding every time you floss, contact your dentist and go in to have them look at your gums.
  4. Use mouthwash twice every time you brush. Swig a capful of mouthwash around in your mouth before brushing to loosen up any food debris in your mouth. Swig another capful after brushing to rinse the toothpaste out and keep your breath fresh. [7]
    • Mouthwash comes in two styles: cosmetic and therapeutic. Cosmetic mouthwash has hydrogen peroxide to help whiten teeth, but there isn’t a lot of evidence that it helps with this. Therapeutic mouthwashes are designed to curb bad breath. Either option is fine.
    • Mouthwash will help your teeth stay healthy and clean, but it isn’t a replacement for brushing or flossing.
    • If your mouth has a tendency to dry out over the course of the day, mouthwash may help with this.

Whitening Your Teeth

  1. While they aren’t going to solve your problems overnight, the whitening strips will help remove yellowing stains. Pick up some whitening strips to make your teeth a shade or two lighter without visiting the dentist. Keep in mind, you cannot use whitening strips if you’ve had any restorative work done, since the strips may damage the repair. [8]
    • The strips won’t whiten restorative work anyway, so any crowns or implants will stand out more if you use whitening strips.
  2. Brush your teeth before applying the strips. [9] Then, peel the adhesive backing off of the first strip and line it up with your gum line. Press the strip against your teeth and wrap the bottom around the backside of your teeth. Repeat this process with the second strip on your bottom row of teeth. Follow the directions on the box regarding how long you leave the strips on for. [10]
    • Depending on the brand and style of whitening strips you use, you’ll need to leave them on for anywhere from 5 to 45 minutes.
    • Some brands of whitening strips need to be reapplied every day for up to a week.
  3. In your research, you may stumble across a variety of teeth whitening methods involving baking soda, hydrogen peroxide, lemon juice, turmeric, or coconut oil. Avoid all of these treatments. While some of them may make your teeth whiter, they can damage your gums or wear away tooth enamel. Talk to your dentist before using any of these whitening tricks. [11]
    • Anything involving citrus is going to eat away at your natural enamel, which can weaken your teeth over time. Strawberries are a popular whitening method, but they don’t actually do anything. [12]
    • Hydrogen peroxide can irritate your gums and damage the roots of your teeth. Dentists do use peroxide for whitening treatments, but it’s a very unique concentration and formula that you can’t mix at home.
    • Turmeric probably won’t harm anything, but there’s not a lot of evidence that it does anything for the whiteness of your teeth.
    • There’s no evidence that coconut oil or oil pulling have any impact on the whiteness of teeth. [13]

Keeping Your Teeth from Staining

  1. Yes, you should even throw a straw in your hot coffee or tea! It may feel silly drinking everything through a straw, but this is a seriously helpful way to protect your teeth and keep them clean. By using a straw, you keep liquids from coating your teeth, which will protect your enamel. [14]
    • The one exception is water. Water naturally has trace amounts of fluoride in it, which is good for your teeth.
  2. Anything that will stain your carpet will stain your teeth, so try to cut back on your coffee and red wine consumption. Anything high in citrus is also bad for your teeth, since citric acid will eat away your enamel if you consume too much of it. Swap out that lemonade for an ice water the next time you’re cooling off on a hot summer day. [15]
    • You can dilute coffee with cream or milk to reduce the odds that it stains your teeth. Drinking rosé or white wine instead of red wine will help for similar reasons.
    • Soy sauce, curry, and tomato sauce will also cause teeth to stain. These things are fine in moderation, but you may want to rinse your mouth out after eating anything with one of these ingredients in it. [16]
  3. Sugarless gum helps stimulate saliva production, which can help wash out any food particles that are stuck in your teeth. Roughly 20 minutes after your meal, any food particles stuck in your teeth are probably staying there. Throw in a piece of sugarless gum and chew on it for a few minutes. This will help clean your mouth and keep whatever you ate from damaging your teeth. [17]
    • If you use gum with sugar in it, the sugar can wear away your teeth’s enamel which can further expose the yellow dentin underneath.
  4. Tobacco will stain your teeth over time and it will make your teeth turn yellow or brown with prolonged use. Smoking also dramatically increases your risk for lung and oral cancer, so talk to your doctor about how you can quit smoking if you’re a regular tobacco user. [18]
    • There are prescription medications, nicotine patches, nicotine gum, and other options available. Quitting is hard, but it’s well worth it if you want your fabulous smile back!

Working with Your Dentist

  1. Keep a regular schedule with your dentist and see them at least twice a year to get a cleaning and have your teeth examined. There’s no replacement for a good dental cleaning from a professional, and your dentist will catch potential problems ahead of time before they get out of hand. [19]
    • At a dental cleaning, your dentist or hygienist will physically remove any plaque, tartar, and food debris. Then, they’ll polish your teeth and remove any stains. This process is painless, and there’s no good substitute, so don’t skip your dental appointments!
  2. At your next cleaning, ask your dentist about a whitening treatment. Depending on the condition of your teeth, a dentist can apply a mixture of hydrogen peroxide and other whitening agents to remove deep stains and brighten your teeth. They may also give you a mouth guard that fits your teeth and prescribe a whitening gel for you to do this at home. After a few treatments, your teeth will be a few shades brighter. [20]
    • This is always going to be more effective than using at-home whitening strips since a dentist will be able to oversee the treatment and customize it for your teeth.
    • Unfortunately, dental insurance rarely covers whitening procedures since they’re cosmetic.
  3. If your enamel is wearing away because you grind your teeth at night, ask your dentist for a protective mouth guard. They’ll take a mold of your teeth and have a custom mouth guard made to keep your teeth safe while you snooze. When you go to bed, put the mouth guard in to protect your teeth. [21]
    • At first, it may feel a little weird wearing a mouth guard at night. Stick with it, though! You’ll get used to it after a few nights.
  4. Ask your dentist if porcelain veneers are a good idea. This is the best way to get rid of yellow teeth and restore your smile, but it can be an expensive procedure. To get veneers, your dentist will take a mold of your teeth and have a custom cover built for your teeth. Then, they’ll bind the veneer to your enamel to permanently cover it in a layer of shiny, white porcelain. [22]
    • Veneers can cost $400-4,000 a tooth depending on the specific type of material you choose and the dentist performing the work. [23]

    Dental professionals seem to have reached a consensus with whitening strips; they tend to universally recommend Crest’s Whitening Strips as the safest and most effective option.

    If your enamel wears away, the layer of dentin underneath will show through, which is what causes your teeth to appear yellow. Over time, you may experience more sensitivity and you may eventually need a crown or a dental filling, but if you aren't in any pain it isn't the end of the world.

      Tips

      • Outside of whitening strips, teeth whitening products are not regulated particularly well. If you see something on a pharmacy shelf that claims it will whiten your teeth, don’t assume it will work. [24]
