1) Drinking Staining Beverages Too Soon
After whitening, your enamel becomes temporarily more porous, making it easier for dark-colored liquids to seep in and cause stains. The most common culprits?
- Coffee
- Tea
- Red wine
- Cola and dark sodas
What to do instead: For the first 48 hours, stick to clear or light-colored drinks like water, milk, or coconut water. If you must have your coffee fix later on, use a straw to minimize contact with your teeth.
2) Smoking or Vaping
Tobacco products are a guaranteed way to stain teeth and undo your whitening results. The tar and nicotine in cigarettes or vapes cling to enamel and cause yellow or brown discoloration over time. After whitening, the staining effect can be even more intense.
What to do instead: Use your teeth whitening treatment as a motivation to cut back—or quit altogether. Protecting your health and your smile go hand in hand.
3) Eating Highly Pigmented Foods
Just like drinks, dark or brightly colored foods can re-stain teeth quickly. Here are some examples of foods to avoid immediately after whitening:
- Berries (blueberries, blackberries, pomegranates)
- Tomato sauces
- Soy sauce and balsamic vinegar
- Curry
- Beets
What to do instead: Follow a “white diet” for the first 1–3 days post-whitening. Think chicken, rice, cauliflower, plain pasta, bananas, and white fish. These foods won’t interfere with your results. Learn more about how your diet impacts your dental health.
4) Using Colored Mouthwash
Many over-the-counter mouthwashes contain artificial dyes and alcohol. Blue, green, or purple rinses can contribute to discoloration, especially when used soon after whitening. Alcohol-based rinses may also cause sensitivity or dry mouth.
What to do instead: Choose a clear, alcohol-free mouthwash. Better yet, ask your dentist to recommend a gentle rinse suited for post-whitening care.
5) Skipping Oral Hygiene
It may sound obvious, but proper brushing and flossing are critical after whitening. Whitening only changes the color—it doesn’t remove plaque, tartar, or food particles that can contribute to dullness and stains.
What to do instead:
- Brush twice daily with a non-abrasive, whitening-compatible toothpaste.
- Floss daily to keep stains from forming between teeth.
- Rinse your mouth after meals to wash away pigments and acids.
For optimal care and to maintain your whitening results, schedule regular preventive dental visits at BOOM Smiles.
6) Consuming Acidic Foods and Drinks
After whitening, enamel is more sensitive to acid. Acidic foods and beverages can wear down enamel and make your teeth more vulnerable to staining, sensitivity, and decay.
Common acidic offenders include:
- Citrus fruits (lemons, oranges, limes)
- Vinegar-based foods
- Sports drinks and energy drinks
- Soda (yes, even the clear ones!)
What to do instead: Limit acidic foods during the first 48 hours post-whitening. If you do consume them later on, rinse with water afterward and wait 30 minutes before brushing.
7) Brushing Too Soon or Too Hard
Immediately after whitening, your enamel is slightly softer. Brushing too hard or too soon after acidic foods can cause enamel erosion or gum irritation, making your teeth more sensitive.
What to do instead:
- Wait at least 30 minutes after eating or drinking before brushing.
- Use a soft-bristled toothbrush and gentle pressure.
- Opt for a toothpaste designed for sensitive teeth if you feel discomfort.
How Long Will Whitening Last?
How long your results last depends on your habits and maintenance. With proper care, professional whitening results can last six months to two years. But without post-treatment precautions, staining can return in as little as a few weeks.
To maintain your results, consider:
- Using touch-up whitening trays (ask your dentist about safe options)
- Scheduling regular cleanings at BOOM Smiles Hoboken
- Following a stain-conscious diet and routine
- Avoiding tobacco products
