1. Use an anti-aging toothpaste. Your dentist may have recommended an anti-aging toothpaste for sensitive gums, but these types of formulas can also be used by anyone who’s trying to make their teeth whiter naturally. While there are many ingredients that are marketed as whitening agents, studies suggest that fluoride is one of the most effective for removing surface stains from our pearly whites and preventing them from being deposited again on exposed areas of our teeth. In fact, a 2009 study published in Caries Research found that using a toothpaste with 1,100 ppm (parts per million) of fluoride helped subjects achieve whiter results than when they brushed with a 900 ppm version.

2. Mix baking soda with lemon juice. This common kitchen staple has actually been around since ancient times—the ancient Egyptians mixed it with water to clean their teeth! The mild abrasive property of baking soda makes it ideal for gently scrubbing away surface stains while the antibacterial properties of lemon juice get rid of bad breath and plaque. Still not convinced? A 2013 study published in International Journal of Cosmetic Science even demonstrated that brushing your teeth with a mixture containing 4% baking soda could remove coffee and tea stains better than commercial products designed specifically for stain removal!

3. Switch out your old habits. Maybe you’re already religiously brushing twice daily—but you’re doing it wrong! Only brush with fluoride toothpaste twice a day and never after eating sugary foods or drinking alcohol. Fluoride doesn’t break down easily, so if you eat something sweet or acidic after brushing, it might damage your enamel more than help it.

4. Flossing: Flossing’s importance cannot be understated because debris trapped between your teeth can cause serious dental issues over time if left alone—to say nothing of leaving unsightly food particles stuck along your gum line once they begin to decay! Even though most Americans are aware that flossing is important, just 53% reported flossing regularly according to the latest National Health Interview Survey conducted by CDC and US Department of Health & Human Services. If you want to start flossing today, consider investing in an electronic version like Waterpik. Its specially-designed handles work wonders for those with limited dexterity in their hands and its countertop models don’t require any batteries at all!

5. Choose chewing gum wisely. If you prefer avoiding oral hygiene products due to sensitivities or allergies, then chewing sugarless gum instead of eating sweets is a great idea…as long as you choose brands like Spry Xylitol Gum which are formulated to promote healthy teeth while helping fight cavities through neutralizing harmful acids produced by bacteria during digestion.

6. Eat healthy foods high in vitamin C. Many fruits and vegetables are rich in vitamin C, an antioxidant that helps strengthen teeth by making it difficult for bacteria to stick to their surface. This is especially true of citrus fruits like oranges and grapefruits, as well as some leafy greens like spinach. If you’re looking for an affordable way to eat healthier on a regular basis, ask your grocery store to place pre-cut bags of spinach in front of your favorite produce section—it’ll quickly become one of your go-to snacks that won’t cost much money or calories!

7. Drink more water. Most people will agree that it’s a good idea to drink plenty of water every day for proper digestion and strong muscles—you’d be surprised how many people still don’t consume enough H2O!
