A brighter, whiter smile can make a significant difference to your confidence. Teeth whitening is one of the most popular cosmetic treatments offered at Tavistock Dental Practice, and patients often ask whether at-home or in-surgery whitening is the better option.
Both approaches can be highly effective, but each has its own benefits depending on your goals, timeframe, and sensitivity. Here, Dr Jack Johnson explains the differences between the two and how we help you choose the most suitable option for your smile.
Do I Need an Assessment Before Whitening?
Yes. Before any teeth whitening treatment, a thorough dental assessment is essential to ensure the procedure is safe and appropriate for you.
Dr Jack will assess:
- Gum and tooth health
- Existing crowns, fillings, or veneers (which do not whiten)
- Any discoloured teeth that may indicate underlying issues
This careful assessment allows us to set realistic expectations and ensure your whitening results enhance your natural smile safely and effectively.
At-Home Teeth Whitening
From £495
At-home whitening is a popular option for patients who want gradual, controlled, and long-lasting results. Prices start from £495, depending on the whitening gel selected and your individual treatment plan.
How It Works
- A 3D scan (digital impression) or mould is taken of your teeth.
- Custom-made whitening trays are created to fit your teeth precisely.
- Whitening gel is placed into the trays, which are typically worn overnight for 2–3 weeks. Overnight wear usually produces the most effective and consistent results, as the gel can work steadily while you sleep.
Types of Whitening Gel
- Overnight gel – worn while sleeping for gradual whitening and optimal results
- Daytime gel – worn for a couple of hours during the day for those who prefer not to whiten overnight
- Different strengths – carefully selected based on your teeth, sensitivity levels, and desired outcome
Maintenance and Longevity
- The custom trays can be reused for top-up treatments every couple of years using additional whitening gel.
- This makes at-home whitening a flexible, long-term solution.
Benefits of At-Home Whitening
- Excellent and highly predictable results
- Gradual whitening helps reduce the risk of uneven colour changes
- Long-lasting results with the option for easy top-ups
Managing Sensitivity
Some patients may experience temporary tooth sensitivity during whitening. Dr Jack will discuss this with you beforehand and may recommend:
- Using Sensodyne Pronamel or a similar desensitising toothpaste or desensitising agent
- Reducing the duration of tray wear if needed
- Avoiding acidic foods and drinks during treatment
At-home whitening is ideal if you are looking for significant, lasting improvement without rushing the process.
In-Surgery Teeth Whitening
£795
In-surgery whitening is performed during a single, longer appointment, typically lasting around two hours. A professional-strength whitening gel is applied to the teeth and activated using a specialised light to enhance its effect.
What to Expect
- Immediate results, often noticeable straight after the appointment
- A convenient option if you are whitening for a specific event or deadline
Things to Consider
- Results can be less predictable than at-home whitening
- In many cases, in-surgery whitening is followed by at-home top-up treatment to achieve the desired shade
- Tooth sensitivity can still occur, though it is usually shorter in duration
In-surgery whitening works best as a “jump start” to whitening or when rapid improvement is required, but it may not replace the benefits of custom trays for long-term maintenance.

Why Top-Ups and Ongoing Care Matter
Teeth whitening is not permanent. Over time, foods, drinks, and lifestyle habits can gradually reduce brightness.
Having custom whitening trays allows you to refresh your smile whenever needed without the need for further scans or moulds. Maintaining excellent oral hygiene and being mindful of staining foods and drinks will also help your results last longer.
