A bright, white smile can boost your confidence and leave a lasting impression.
But if you’re considering whitening your teeth or have already done so you’re probably wondering: how long does teeth whitening last?
The answer depends on several factors, including the type of whitening treatment you choose and your personal habits. Let’s break it down so you know what to expect.
What Is Teeth Whitening and How Does It Work?
Teeth whitening is a cosmetic dental procedure designed to lighten the colour of your teeth and remove stains caused by food, drinks, smoking, and ageing.
At Centrepoint Dental Care, we offer professional whitening treatments that use safe, high-quality whitening agents. These penetrate the tooth enamel to break down stubborn stains giving you a noticeably brighter smile in just one session.
1. The Average Duration of Teeth Whitening Results
On average, professional in-chair teeth whitening can last anywhere from 6 months to 2 years. The results vary depending on your lifestyle, diet, and how well you care for your teeth after treatment.
At-home whitening kits provided by your dentist can also produce long-lasting results though they may need top-ups more often than in-chair treatments.
2. Factors That Affect How Long Whitening Lasts
The longevity of your whitening results is influenced by:
- Diet – Drinks like coffee, tea, red wine, and cola can cause new stains
- Oral hygiene – Brushing, flossing, and regular dental cleans help preserve your results
- Smoking – Tobacco products are one of the fastest ways to discolour teeth
- Type of treatment – Professional whitening lasts longer than store-bought kits
- Natural enamel colour – Thicker, healthier enamel tends to hold whitening longer
3. How to Make Your Whitening Results Last Longer
With the right care, you can extend your whitening results and enjoy your bright smile for as long as possible. Here are some tips:
- Rinse your mouth with water after drinking coffee, tea, or wine
- Use a straw for dark-coloured drinks to reduce contact with teeth
- Avoid smoking or using tobacco products
- Brush twice a day with a whitening-friendly toothpaste
- Book regular dental cleans at Centrepoint Dental Care
4. Professional Whitening vs Over-the-Counter Kits
It’s no secret that professional whitening lasts longer than over-the-counter kits. But why? Dentist supervised treatments use higher-strength whitening agents that are applied safely and effectively.
They’re also tailored to your teeth, which means you get even results without unnecessary sensitivity.
In contrast, store-bought kits often have lower concentrations of active ingredients, meaning results fade faster and top-ups are needed more frequently.
5. When to Consider a Touch-Up Treatment
Even with excellent care, your teeth will gradually pick up stains over time. That’s why many patients choose a touch-up treatment every 6–12 months to keep their smile looking fresh.
Our team at Centrepoint Dental Care can help you decide the best schedule for maintaining your ideal shade.
