How to Achieve Natural Teeth Whitening with Baking Soda


Woman with a beautiful smile

A bright smile can be a true confidence booster. Unfortunately, professional whitening treatments can be expensive, and many over-the-counter products contain harsh chemicals. Luckily, there is a natural and affordable way to whiten your teeth at home using baking soda.

Baking soda, also known as sodium bicarbonate, is a common household item that could be the secret to natural teeth whitening. It's mildly abrasive, which helps remove surface stains from your teeth. Plus, it's alkaline, which can help neutralize acids in your mouth that contribute to tooth decay.

You might ask, "Does natural teeth whitening work?" Luckily, baking soda is one of the simplest ways to see real results without a complicated routine.

Your diet, daily habits, and even genetics play a role in how bright your smile looks. While baking soda teeth whitening can help, you'll still want to maintain a routine that protects your enamel long term.

How to Use Baking Soda as Natural Teeth Whitening: Step By Step

Here are step-by-step instructions on how to use baking soda for natural teeth whitening:

Step 1: Gather Your Materials

You'll need:

  • Baking soda (make sure it's food-grade)
  • Water
  • A small bowl
  • A soft-bristled toothbrush

Some people like to add a drop of hydrogen peroxide for extra whitening power, but that's optional. If you've been searching for how to whiten teeth naturally, this method is a good place to start since it only takes a couple of minutes to prepare.

Step 2: Make the Paste

Mix about a tablespoon of baking soda with just enough water to form a paste. It should be thick enough to stick to your toothbrush. If you're using hydrogen peroxide, you can substitute it for water.

If you want to know how to make a natural teeth whitener without any additives, you can simply stick with baking soda and water, since it's effective on its own.

Step 3: Apply and Brush

Dip your toothbrush into the paste and start brushing. Use gentle, circular motions and make sure to coat all of your teeth. Don't scrub too hard because baking soda is abrasive. Think of this as polishing your teeth rather than scrubbing them-you're gently removing stains over time, not forcing an instant change.

Step 4: Wait and Rinse

Let the paste sit on your teeth for about two minutes. Then, rinse thoroughly with water. Make sure to spit it all out - you don't want to swallow baking soda. It's important to thoroughly rinse out your mouth after whitening because leftover residue can leave a gritty texture on your teeth.

At this point, you might wonder, "What is a natural teeth whitener that freshens breath as well?" Following up with regular toothpaste helps give you that clean, minty finish.

How to Brush Your Teeth With Baking Soda

Brushing with baking soda is a bit different from using regular toothpaste. Here are some tips on brushing your teeth with baking soda:

  • Be gentle: Baking soda is more abrasive than toothpaste, so you don't need to apply much pressure.
  • Focus on stained areas: Pay extra attention to spots where you have noticeable discoloration.
  • Don't overdo it: Use this method no more than a couple of times a week to avoid damaging your enamel.
  • Follow up with regular brushing: After rinsing out the baking soda, brush with your normal toothpaste to get that minty fresh feeling.

Keep in mind that baking soda doesn't contain fluoride, so it's not a replacement for your typical oral care routine. Try to think of it as a supplement to your usual brushing and flossing routine.

If you've read about lemon juice or apple cider vinegar as alternatives, be careful. Acids can weaken enamel quickly, making baking soda one of the safer options for natural teeth whitening.

While baking soda can be effective in helping whiten your teeth, it's still important to maintain a healthy oral hygiene routine. You should brush twice daily with a fluoride toothpaste. Floss regularly, and don't skip your dental check-ups. It's also a good idea to eat a balanced diet that's low in sugary and acidic foods. Stains build up slowly, so the more consistent you are with your overall care, the longer your results will last.

Electric toothbrushes can be helpful in achieving a more thorough cleaning. If you're worried about tooth sensitivity or have existing dental work, you should talk to your dentist before starting any whitening regimen. They can provide you with personalized advice and suggest professional treatments if needed.

Asking your dentist how often to try baking soda teeth whitening can save you from overuse while still giving you the benefits of a brighter smile.

How Fast Does Baking Soda Whiten Teeth?

The results of using baking soda for teeth whitening vary from person to person. Some people notice a difference just after a few uses, while others notice a difference after a few weeks of consistent use. It depends on a few factors:

  • How stained your teeth were to begin with
  • What caused the stains (coffee, tea, smoking, etc.)
  • How often you use the baking soda treatment
  • Your overall oral hygiene habits

You can't expect a miracle to happen overnight because natural teeth whitening is a gradual process. With regular use, you might notice a difference and see noticeable improvement within a month.

Another thing to keep in mind is that, as a natural way to whiten teeth, baking soda works best on surface stains. For deeper discoloration, you might need to consider cosmetic dentistry. Professional whitening is the quickest way to see a dramatic change, but baking soda is a great option to help maintain results.

Final Thoughts

Baking soda is a great form of natural teeth whitening because it's affordable, readily available, and free of harsh chemicals.

Baking soda is a natural teeth whitening method that works for most - but could be too abrasive for people with sensitive gums. If you feel any pain or sensitivity, stop using it and give us a call. It's better to adjust early than risk wearing down enamel with too much at-home natural teeth whitening.

Also, remember that good oral hygiene is the foundation for a white smile, so it's important to keep up with your brushing and flossing routine. Natural teeth whitening methods are best thought of as boosters, not replacements, for your daily care.

If you have more severe tooth discoloration and are considering ADA-approved teeth whitening products or want to discuss professional teeth whitening treatments with your dentist, Smiles of Cary can help.
