Frequently
Asked
Questions

View All

Thinking about teeth whitening? You may have questions about the process, results, and whether it’s the right choice for you. Here are some of the most common queries we receive.

Is teeth whitening safe for my enamel?

Yes. When performed under professional supervision, teeth whitening is safe and does not harm the enamel. We use regulated products and clinically approved methods to protect your teeth and gums.

How long does the whitening treatment take?

Treatment times vary. In-practice whitening usually takes about an hour, while at-home kits are typically used daily over 1–2 weeks. We’ll recommend the most suitable option based on your needs.

Will it work on a discoloured tooth?

Teeth whitening can improve many types of discolouration, but stains caused by injury or certain medications may be less responsive. We’ll assess your teeth and explain the best options available.

How long do the results last?

Results can last from several months to a few years, depending on your oral hygiene and lifestyle. Avoiding staining foods and drinks and keeping up with regular dental care will help extend the effects.

Can I whiten my teeth if I have fillings or crowns?

Whitening treatments do not change the colour of crowns, veneers, or fillings. We’ll discuss how this may impact your overall result and whether alternative solutions might be more suitable.

The Process

Pre-Treatment

Before starting any teeth whitening treatment, we carry out a full dental examination to check your oral health and identify the type of discolouration. This ensures the treatment is safe and effective for your individual needs.

Treatment

Our at-home teeth whitening treatment uses custom-made trays and professional whitening gel to brighten your smile gradually and safely. We’ll guide you on how to use it properly at home, with treatment tailored to your goals and oral health.

Post-Treatment

After your whitening treatment, we’ll provide advice on how to maintain your results. This includes oral hygiene tips, dietary guidance, and regular dental check-ups to help keep your smile bright.

Sides Effects & Risks

Some people may experience temporary sensitivity or mild gum irritation following treatment. These effects are usually short-lived. We’ll explain what to expect and how to manage any discomfort safely.
