Post-Dental Whitening Instructions

Genesis Dentists – North Melbourne

A brighter smile is one of the most effective ways to boost your confidence. At Genesis Dentists North Melbourne, we provide professional teeth whitening treatments designed to safely and effectively lighten your teeth. To make sure your results last and to minimise sensitivity, it’s important to follow the right post-whitening care instructions.
This guide explains everything you need to know about post-whitening aftercare—from what to eat, what to avoid, and how to maintain your white smile long-term.

Immediate Care After Teeth Whitening (First 24–48 Hours)

What to Expect

Tooth Sensitivity: Mild to moderate sensitivity is common and temporary.
Gum Irritation: Minor irritation may occur and usually settles within 24–48 hours.
Colour Changes: Teeth may appear whiter immediately, with full results visible within 7–14
days.

Pain & Sensitivity Relief

Take over-the-counter pain relief such as ibuprofen or Panadol if needed.
Brush with sensitive toothpaste (e.g., Sensodyne, neutrofluor 5000ppm).
Apply desensitising gel if provided by our clinic.

The “White Diet” – Foods & Drinks to Avoid

The first 48 hours after teeth whitening are critical. During this time, your enamel is more porous
and prone to staining.

Avoid Dark-Coloured Items

Coffee, tea, red wine, cola, dark sodas
Fruit juices such as cranberry, grape, or pomegranate
Sports drinks with artificial colours

Avoid Staining Foods

Berries, tomato-based sauces, soy sauce, balsamic vinegar
Curry and turmeric-based dishes
Dark chocolate, coloured lollies or popsicles

Other Items to Avoid

Tobacco products (smoking or chewing)
Coloured mouthwashes
Lipstick (within the first 24 hours)

Recommended “White Foods”

Safer food options during the first 2 days include:

Chicken, turkey, white fish
White rice, pasta (without coloured sauces)
Bread, crackers, cereals
Milk, yogurt, white cheese
Bananas, white grapes, cauliflower, onions
Clear drinks such as water or clear soda

Ongoing Care for Your White Smile

Daily Oral Hygiene

Brush twice daily with fluoride toothpaste using a soft-bristled brush
Floss once a day

Long-Term Maintenance

Drinking Tips
