You’ve just stepped out of the studio, glanced in the mirror, and seen that brilliant, new smile staring back at you. It’s a confidence booster like no other. At We Whiten, we specialize in delivering these dramatic results through our professional treatments, often lifting stains by up to 10 shades in a single 90-minute session. But achieving that dazzling look is only half the battle; maintaining it is where the real work begins.
Just like a great hair color or a fresh manicure, your new smile requires maintenance to stay pristine. Without the right habits, those pearly whites can fade back to their previous shade faster than you’d like. That is why understanding the proper aftercare for teeth whitening is essential for protecting your investment and keeping your confidence high for the long haul.
The First 24 Hours: The “White Diet”
The first 24 to 48 hours following your appointment are critical. During the whitening process, the pores of your tooth enamel remain open, making them highly susceptible to staining. Think of your teeth like a dry sponge during this window, they are ready to absorb whatever color touches them.
What to Avoid
To ensure your aftercare for teeth whitening is effective, We Whiten experts recommend sticking to a strict “White Diet” for at least 24 hours. If a food or drink would stain a white t-shirt, it will stain your teeth.
- Beverages: Steer clear of coffee, tea, red wine, and dark sodas. Even fruit juices with vibrant colors should be avoided.
- Foods: Avoid berries, soy sauce, tomato-based sauces (like marinara), dark chocolate, and curry.
- Habits: Smoking or vaping can instantly reverse your results during this sensitive period.
We also recommend avoiding all food and drinks (except water) for the first 2 hours immediately after your appointment to allow the whitening process to settle.
Recommended Products
Hydration is key. Water is the absolute best thing you can consume right now. It helps wash away bacteria and food particles that might otherwise settle on your enamel.

Long-Term Maintenance Strategies
Once you’ve made it past the initial 24-hour window, you can relax a little, but don’t let your guard down completely. Long-term maintenance is about building small, sustainable habits that protect your smile.
One of the easiest tricks is to use a straw when drinking beverages that are known to stain. This bypasses the front of your teeth, minimizing contact with pigments. Additionally, maintaining a robust oral hygiene routine—brushing twice a day and flossing daily—prevents plaque buildup, which attracts stains.
Regular touch-ups are also a vital part of aftercare for teeth whitening. At We Whiten, we offer membership options that make it affordable and easy to pop in for a refresh, ensuring your smile never loses its luster.
Handling Sensitivity and Staining
A common worry with whitening is sensitivity. Fortunately, We Whiten uses a specialized organic gel that contains no preservatives or harsh chemicals. In fact, about 95% of our clients report little to no pain.
However, if you do experience minor sensitivity, it is typically short-term and fades within 24 to 48 hours. Using a desensitizing toothpaste or gel can provide quick relief. If you notice new staining occurring months down the line, don’t panic. This is natural, especially if you enjoy your morning coffee. This is simply a sign that it’s time for a maintenance appointment or to utilize at-home products.
