What To Do After Using Whitening Strips

Published: Nov 14, 2024

After using whitening strips, it's natural to want to maintain that fresh, radiant look. By following a few simple steps, you can preserve your bright smile and care for your long-term oral health, all while protecting your teeth from sensitivity. With the proper post-whitening routine, you can keep your smile as vibrant as your personality and allow your confidence to shine through every time you share it with the world. 

Key Takeaways

  1. Avoid Immediate Brushing: After using whitening strips, wait before brushing your teeth. Brushing too soon can irritate your enamel, which may be temporarily more sensitive.

  2. Avoid Stain-Causing Habits: For at least 48 hours after whitening, steer clear of foods, drinks and habits that can stain your teeth. This includes avoiding coffee, tea, alcohol and tobacco products, which can all dull your smile and counteract your whitening efforts.

  3. Maintain a Comprehensive Oral Care Routine: Keep your smile radiant with a consistent oral care regimen. Regular brushing with whitening toothpaste, flossing and incorporating practices like oil pulling can help you preserve your results.

Immediately After Using Whitening Strips

Once your whitening strips have done their magic, it’s important to remove them carefully. Gently peel them off and rinse your mouth with water or an alcohol-free mouthwash to clear away any leftover residue.

When To Brush Your Teeth

You might be tempted to brush right away, but most dentists recommend to wait at least 30 minutes. Whitening strips can make your enamel temporarily more porous, so brushing too soon can lead to sensitivity or irritation and even erosion of the enamel. When you do brush, opt for a soft-bristle brush for gentle cleaning. Be sure to rinse off all the whitening gel thoroughly. Leaving it on for too long can:

  • Damage your enamel
  • Increase sensitivity
  • Cause uneven whitening (which no one wants)

What To Avoid Post-Whitening

To keep your smile shining bright after your whitening treatment, being mindful of certain foods, beverages and habits is essential. Your teeth can be more porous and more susceptible to staining in the first 48 hours, so it's important to take extra precautions during this period. Here’s a detailed look at what you should avoid to ensure long-lasting results:

  • Dark Beverages: Drinks like coffee, tea, red wine and soda are notorious for their staining abilities. These beverages contain chromogens, pigment-producing substances that can easily cling to your teeth’s surface, leading to discoloration. While it's best to avoid these drinks in the days immediately following your whitening treatment, there are steps you can take if you can’t resist your daily cup of coffee or tea.

    To minimize staining, make sure to rinse your mouth with water after consuming these beverages. This simple step can help wash away lingering pigments before they settle on your teeth. Drinking water alongside dark beverages can also dilute the chromogens and reduce the risk of staining.

  • Dark-Colored Foods: Certain foods, such as berries, beets and sauces like soy sauce, tomato sauce and curry, are packed with pigments that can dull your freshly whitened smile. During the initial post-treatment phase, opt for lighter, less pigmented foods like bananas, plain yogurt and steamed vegetables.

    For sauces, while alternatives can be limited, you can try alfredo sauce, olive oil-based dressings or a light cheese sauce. If you enjoy curry, consider turmeric-free or coconut milk-based versions, which are less likely to stain. To further protect your smile, rinse your mouth or drink water after meals.

  • Tobacco: Smoking or using chewing tobacco can quickly stain your teeth and undo all the hard work you’ve put into whitening them. Tobacco not only causes discoloration but also leads to more severe oral health issues. Avoiding tobacco products entirely is the best way to maintain both the brightness of your smile and your overall oral health.

  • Acidic Foods and Drinks: While less commonly mentioned, acidic foods and drinks like citrus fruits, vinegar and energy drinks can weaken the enamel and make your teeth more vulnerable to staining. Consider avoiding these, especially in the first few days post-whitening, to protect your enamel and keep your teeth looking their best.

In the first 48 hours after whitening, avoiding these items helps maintain your bright smile and reduce the chance of immediate staining. By continuing to be mindful of these habits, you can preserve your bright smile and reduce the need for frequent whitening treatments over time.

Tips For Keeping Your Teeth White Long-Term

Maintaining your bright smile goes beyond just avoiding stains. Here are some practical tips to help keep your teeth white and healthy:

  1. Stick to a Consistent Oral Care Routine: Brush your teeth twice a day with a whitening toothpaste and floss daily to remove plaque and food particles that a toothbrush might miss. Use a gentle soft-bristle brush to prevent irritation and sensitivity while removing unwanted stains.
     
  2. Consider Oil Pulling: Oil pulling is a natural method that involves swishing coconut oil around your mouth before brushing. Coconut oil contains lauric acid, which has natural antibacterial properties. Swishing a tablespoon (10-15 ml) of coconut oil in your mouth for 10-15 minutes helps break down bacteria and plaque buildup, which might help whiten your smile. This remedy can be a great complement to your post-whitening care and overall oral health.

  3. Stay Hydrated: Drinking plenty of water throughout the day does more than just keep you refreshed — it helps rinse away food particles that can stick to your teeth, reducing the likelihood of bacterial buildup. Water also helps dilute acids in your mouth, making them less harsh on your enamel.

  4. Visit Your Dentist Regularly: Professional cleanings and check-ups can help keep your teeth healthy and free from stains that might be hard to remove at home.

By following these tips, you’ll not only help keep your teeth white but also maintain overall oral health. Consistency is key, and with the right habits, you can enjoy a bright, confident smile every day. 

When To Touch up and Re-Whiten Your Teeth

Wondering when it’s time for a touch-up? The ideal time for touch-ups depends on the type of whitening treatment you use and your personal habits. Here’s a more detailed breakdown:

For the best results, it’s always a good idea to consult with your dentist or healthcare professional. They can offer personalized advice to prevent overuse and keep your enamel safe while achieving the bright smile you want.
