What is teeth whitening?
While brushing and surface treatments can tackle external stains, teeth whitening is the only robust and permanent solution to lighten the shade of your teeth. It goes deeper into the tooth’s surface to remove embedded discolouration. We offer two highly effective whitening systems that deliver dramatic results.
With options like Boutique Whitening and Enlighten Smiles, you have the flexibility to select the treatment that suits your needs. Additionally, you can choose between at-home treatments, in-clinic treatments or a combination of both to achieve your dream smile. We always perform these procedures under professional supervision to ensure safety and effectiveness.

The Treatment Journey
Every patient is unique, but here’s what you can expect from your treatment journey towards sparkling teeth with Castle Dental Care.
Book your consultation
The first step towards brighter teeth is scheduling a consultation with us to determine if you’re a suitable candidate. We’ll discuss your aesthetic goals and review your oral health history. We’ll also examine your teeth and gums to ensure they are in good enough condition to undergo treatment.
The treatment begins
Once you decide to proceed, we’ll scan your teeth to create custom trays for your at-home whitening solution. Once the treatment is finished, you’ll return to the practice for a final review.
Smile with confidence
After the final session, you’ll enjoy noticeably whiter teeth that allow you to smile with confidence. We’ll provide aftercare advice to help maintain your results and prevent future staining.
Frequently Asked
Questions (FAQs)
Find the answers to the most commonly asked questions regarding teeth whitening below:
What are the best teeth whitening treatment options?
When it comes to teeth whitening, your options include at-practice professional treatments and at-home whitening kits. For the best and safest results, we recommend teeth whitening under a certified dentist’s supervision, as it ensures access to the most effective treatments while ensuring procedural safety.
Is teeth whitening permanent?
While teeth whitening can deliver long-lasting results, it’s important to understand that the effects will naturally fade over time. To keep smiling brightly, periodic top-up treatments are recommended every few months.
How long does it take for teeth whitening results to show?
The time it takes to notice the effects of teeth whitening can vary depending on the type of treatment and the level of staining. Typically, you’ll start seeing improvements after just one session. However, to reach your desired level of whiteness, you may need to undergo multiple treatments.
Is it normal to experience sensitivity after teeth whitening?
Some patients experience temporary sensitivity after teeth whitening as a result of the bleaching agents used in the treatment. This sensitivity typically fades within a few days. However, if you notice more intense or ongoing discomfort, please contact us for further advice.
Whitening Without Painful Sensitivity
Professional teeth whitening is the only way to achieve dramatic results without the risk of increased sensitivity. Over-the-counter kits do not contain enough whitening agents to be able to achieve a significant change in shade. And there is also the risk of damage to your gums and enamel when you choose non-professional whitening.
Sensitivity occurs due to small pores in your teeth opening to allow the whitening agent to penetrate the inner layer. This can leave you with painful teeth that are sensitive to hot and cold. With professional teeth whitening, we use enamel-friendly ingredients that will not cause increased sensitivity. We also use custom-made whitening trays to protect your gums from damage.
Wondering about the cost of treatment?
With our commitment to transparency, we ensure you know exactly what to expect both in terms of your treatment journey and with regard to any costs.
