Teeth whitening: how does it work?
Teeth whitening works by using safe bleaching agents, such as hydrogen peroxide or carbamide peroxide, to break down stains on the enamel.
At Premier Smile Dental Excellence, we use professional-grade products that penetrate the tooth’s surface to remove discolouration caused by food, drinks, tobacco, and ageing.
Our in-practice treatments, such as Zoom! Whitening, provide immediate results in about an hour.
For those who prefer at-home whitening, we offer custom trays and gels, allowing you to whiten your teeth at your convenience with professional guidance.
Methods of teeth whitening
At Premier Smile Dental Excellence, we provide two main types of teeth whitening: in-practice and at-home treatments.
Our in-practice treatment uses advanced technology, such as the Zoom! light-activated whitening system, to deliver fast and dramatic results in a single visit.
For at-home whitening, we offer customised trays and professional-grade gels that allow you to whiten your teeth gradually over a few weeks.
Both options are safe and effective, tailored to your preferences and lifestyle.
Whether you choose in-practice or at-home whitening, we ensure optimal results with the least sensitivity.
We believe in taking the time to fully understand your dental health, concerns, and goals.
Teeth whitening: costs
The cost of teeth whitening can vary depending on the type of treatment chosen.
At Premier Smile Dental Excellence, in-practice whitening typically costs more due to the immediate and long-lasting results it provides, while our at-home whitening kits offer a more affordable option.
We believe in transparent pricing and offer flexible payment plans to make professional teeth whitening in Leighton Buzzard accessible for all our patients.
During your consultation, we’ll discuss the best options for your budget and desired results.
Teeth whitening: does it hurt?
Teeth whitening is generally a comfortable procedure, though some patients may experience temporary sensitivity.
At Premier Smile Dental Excellence, we take every precaution to ensure your treatment is as painless as possible.
Our professional-grade whitening gels are formulated to minimise sensitivity, and we also offer desensitising treatments if needed.
Most patients report little to no discomfort during and after the procedure.
With our expertise and gentle approach, your teeth whitening in Leighton Buzzard will be a pleasant experience with beautiful results.



How long does teeth whitening last?
The results of professional teeth whitening can last anywhere from six months to two years, depending on your lifestyle and oral hygiene habits.
At Premier Smile Dental Excellence, we use high-quality products that deliver long-lasting results.
To prolong the effects of your whitening treatment, we recommend maintaining good oral hygiene, avoiding stain-causing foods and beverages, and attending regular dental check-ups.
For patients who want to maintain their bright smile over time, we also offer touch-up kits for at-home use.
Teeth whitening before and after
Teeth whitening at Premier Smile Dental Excellence can transform your smile, making your teeth several shades lighter in just one session.
Before the procedure, we assess your teeth to ensure they’re healthy enough for whitening. After the treatment, you’ll notice an immediate improvement in the brightness of your smile.
We use advanced imaging to show you the difference before and after, so you can see the results of your teeth whitening in Leighton Buzzard and feel confident in your new, radiant smile.
Teeth whitening side effects
Teeth whitening is a safe procedure when performed under professional supervision, but it can sometimes lead to temporary side effects like tooth sensitivity or gum irritation.
At Premier Smile Dental Excellence, we take steps to minimise these risks by using gentle, effective products and tailoring each treatment to your needs.
We also provide guidance on how to manage any post-treatment sensitivity.
If you have concerns about potential side effects, our team will work with you to ensure a comfortable and successful teeth whitening in Leighton Buzzard.

GabbieTrustindex verifies that the original source of the review is Google. I recently visited Dr. Vasfi for two very lengthy root canal appointments after being referred to her by my regular dentist. To say I was absolutely dreading these procedures was an understatement, but I needn’t have worried at all. Nooshin is very calm, kind, and patient, and her demeanour immediately puts you at ease. As an anxious and nervous patient, the entire team at Premier Smile Dental Excellence went out of their way to make sure that I was looked after and answered my many questions. The overall procedure was painless, and the actual root canal work that was undertaken was incredibly thorough. Nooshin talks you through each stage of the root canal process, so you know exactly what to expect during the procedures (you can even choose what music you might like to be played during your treatment if this helps to relax you too). Nooshin takes x-rays and photographs of your teeth before and after treatment so you can really see the difference she makes! If you need any kind of intricate dental work done (especially if you have been putting this off) then I wouldn’t hesitate to recommend Dr Vasfi, her caring nature, expertise and attention to the personalised level of dental care she provides is second to none. Thank you Nooshin and the team - I can't thank you enough. Josh DuffyTrustindex verifies that the original source of the review is Google.
