Teeth Whitening Aftercare

Your enamel is slightly more porous right after whitening, which means the next 48 hours determine how long your results last. The “White Diet” is your best friend right now.

  • First 24 Hours

The most important window

These first few hours set the foundation for a smooth recovery. Keep these in mind tonight.

What to Do

  • Follow the White Diet strictly for 48 hours — only white and light-colored foods and drinks.
  • Drink water — it's the safest beverage for the next two days.
  • Use a sensitivity toothpaste (like Sensodyne) if you experience any tooth sensitivity.
  • Brush gently with a soft-bristled toothbrush.
  • Keep follow-up tray wear sessions as instructed if you received take-home trays.

What to Do

  • No coffee, tea, or red wine — these are the biggest culprits for re-staining.
  • No dark sodas, juices, or sports drinks.
  • No berries, tomatoes, or dark sauces.
  • No smoking or tobacco — this will stain your teeth immediately.
  • Avoid very hot or very cold foods if you're experiencing sensitivity.
  • No acidic foods (citrus, vinegar-based dressings) — they can worsen sensitivity.
  • Days 2-7

What healing looks like

Most people feel noticeably better by day 3. Here’s what’s normal and what’s worth a call.

Normal Signs of Healing

  • Tooth sensitivity to temperature or sweet foods for 24–72 hours — very common.
  • Slight gum sensitivity if tray whitening was used — resolves within 48 hours.
  • Teeth may look slightly uneven at first — this evens out as hydration returns.
  • Some people experience “zingers” — brief, sharp sensitivity spikes — for 1–2 days.

Watch Out For

  • Sensitivity that is severe and continues past 5–7 days without improvement.
  • White patches or spots on your gums — a sign of tissue irritation from the bleaching gel.
  • Significant gum irritation or blistering.
  • Sensitivity that makes eating or drinking difficult beyond 3 days.
  • Nutrition

What to eat right now

Your food choices in the next few days directly affect how fast you heal. Keep it simple.

Eat This

  • White chicken or turkey breast
  • White fish (cod, tilapia, halibut)
  • White rice and plain pasta
  • Cauliflower and white mushrooms
  • Bananas and white peaches
  • White cheese and plain yogurt
  • Milk and water
  • Eggs (scrambled or boiled)

Skip This

  • Coffee and tea (any color)
  • Red wine and dark beers
  • Berries and dark-colored fruits
  • Tomato sauce and ketchup
  • Soy sauce, teriyaki, and curry
  • Dark sodas and sports drinks
  • Mustard and balsamic vinegar
  • Chocolate and dark candy
