How long whitening lasts depends on the method you use and your daily habits. With good maintenance, results typically last from about 6 months up to 3 years (NHS). 
What makes results fade faster?
Pigmented food and drinks and tobacco are the big culprits. Coffee, tea, red wine, and smoking are all known to stain enamel and shorten the life of a whitening treatment (NHS). 
How to make your results last
- Be mindful with stains. Cut back on coffee, tea, and red wine when you can. If you indulge, sip water after and brush later.
- Keep a solid routine. Brush twice a day, floss daily, and see your dentist regularly.
- Top up periodically. Gentle touch-ups help you maintain the shade you like instead of starting from zero each time.
A simple maintenance plan
- At-home touch-ups: Use Remi Teeth Whitening Gel for occasional refresh sessions. Always follow the gel’s directions and listen to your teeth. If you feel sensitivity, take a break and use a sensitivity toothpaste.
- If you wear a night guard or retainer: Keep the appliance clean so stains do not transfer back to teeth. Our Night Guard Cleaning + Teeth Whitening Foam helps lift surface stains on appliances and freshens them between uses.
- Daily habits that help: Rinse after dark drinks, use a straw for iced coffee or tea, and avoid smoking.
When to check with your dentist
If you have cavities, gum issues, or significant sensitivity, talk to your dentist before whitening or re-whitening. A quick check ensures whitening is the right move for you.
