Tooth Whitening FAQs:

Tooth whitening explained

Tooth whitening is a cosmetic dental procedure designed to lighten the colour of your teeth and remove stains. It’s a popular method to enhance your smile and boost confidence by removing surface stains and tooth discolouration caused by drinking coffee or smoking.

Who carries out the whitening treatment?

All whitening treatments are administered by our CQC and GDC-approved cosmetic dentists.

How does tooth whitening work?

Most tooth-whitening products use bleaching agents like hydrogen peroxide. Whitening agents and forums enter through pores in your teeth and gradually break down stains into smaller pieces, making the discolouration less and less through each wear. The process generally involves applying the whitening formula to the teeth using trays. Laser whitening works similarly but is carried out on a chairside with a UV light to speed up results.

What are the different types of tooth whitening?

There are various methods to whiten teeth, from over-the-counter products, including whitening toothpaste, strips, and gels, to professional options supplied by dentists. Patients have the choice between several brands of professional tooth whitening involving in-office treatments like Boutique Whitening (take-home kit), Enlighten Evolution (in-office and take-home), and Philips Zoom Whitening (in-office and take-home).

Is tooth whitening safe?

When done correctly and under the direction of dental professionals, tooth whitening is generally considered safe and effective. However, it’s essential to follow product instructions carefully. It’s also essential to consult a dentist before starting any whitening treatment, especially for those with dental issues like tooth sensitivity.

How long does it take to see results?

Results vary depending on the method and brand used and how heavy your teeth are stained or discoloured. Some people notice a difference after the first application, while others may take weeks or months to notice white teeth. It’s important to remember to be patient; with each application, the formulas reverse years’ worth of stains, so it can be a journey for some patients.

If you’re using at-home kits, you’ll wear them for a short time every day or overnight for two to three weeks. Whitening treatments carried out in the practice usually take 60 minutes.

Are there any side effects?

Common side effects include tooth sensitivity and gum irritation. For example, it’s normal to experience tooth sensitivity within the first 36 hours, which should subside following this time frame. During your initial consultation, we will determine whether you suffer from hyper-sensitivity and can recommend formulas with lower levels of peroxide or carbamide to reduce sensitivity or pain.

Can anyone get tooth whitening?

While many people can benefit from tooth whitening, it’s not always suitable for everyone. For example, pregnant or under 18. The General Dental Council (GDC) advises that whilst your teeth are still developing, it’s best not to try whitening until you are 18 years of age. It’s also not recommended for those with seriously damaged teeth or those with a peroxide allergy. Source.

How long do the results last?

The longevity of results depends on lifestyle factors such as diet and oral hygiene, as well as the type of whitening method you opt for and brand. Avoiding foods and beverages that stain teeth and maintaining good oral care can help prolong the effects of tooth whitening. As a general rule, patients should expect results to last between 12 and 36 months.

Can I whiten my teeth at home?

Yes, there are several at-home tooth whitening options available like Boutique By Day and Boutique By Night. Explore more here. It’s essential to choose products with the British Dental Association (BDA) seal of approval for safety and efficacy.

I've been seeing George for over 15 years. One of my best decisions. Teeth needed serious attention and were immediately "rescued". They have been maintained to an excellent level ever since. Fantastic treatment and continuing results.

American 🇺🇸 Pilot with a very busy schedule. Was in London of one of my many layovers summer 2023. Had not been to a dentist in sometime. Was in need of a deep scaling for oral hygiene and start pains of a Carrie. I’m one of those and for all work completed under N20 (Nitrous Oxide Gas) for seems to be only way. He was able to see me and complete this matter swiftly and professionally. Didn’t scare me out of the chair. Recommend this practice and would return on a layover.

I recently had the pleasure of visiting CapCityDental for a dental cleaning, and I must say, it was an exceptional experience from start to finish. As someone who prioritizes oral health, I've had my fair share of dental appointments, but this one truly stood out. From the moment I walked in, I felt welcomed and at ease, setting the tone for a fantastic dental cleaning session. The moment I stepped into the clinic, the friendly receptionist - Michael, greeted me with a warm smile and efficiently took care of the check-in process. The waiting area was clean, comfortable, and featured modern decor that helped create a relaxing atmosphere. It was clear that the staff at at CapCityDental value professionalism and patient comfort. Dr. George, the senior dental hygienist was a true expert in his field. He took the time to explain the entire cleaning process, making sure I was comfortable and informed every step of the way. Indeed, it did feel like a warm hug. Furthermore, his dental nurse Marilou was just a gem. Her gentle yet thorough approach put me at ease, and I could sense her commitment to delivering top-notch oral care. It's evident that CapCityDental has a team that's passionate about what they do. What truly sets CapCityDental apart was their dedication to personalized care and patient education. The hygienist nurse took the time to discuss my oral health habits and offered valuable insights on how to improve my routine. She answered all my questions patiently, showing a genuine interest in my oral health journey. This level of individualized attention left a lasting impression on me. In conclusion, my dental cleaning experience at CapCityDental was nothing short of outstanding. From the moment I walked in to the moment I left, I felt valued as a patient and confident in the care I received. The professionalism, expertise, and genuine concern for patient well-being were evident throughout. I wholeheartedly recommend this clinic to anyone seeking exceptional dental care in a welcoming and modern environment. I'm already looking forward to my next visit!

I had emergency root canal with George and team, and subsequent fillings and hygiene. The service and quality of finish was impeccable. Excellent communication and a focus on patient experience puts you at ease from the start. The after care is also excellent. Couldn’t recommend enough.

I have been so incredibly impressed with my experiences at CAP City Dental. George has been so professional, caring and clearly has a wealth of experience within dentistry. I have had a variety of treatments over many years with George and he is the only dentist I have ever come across that has been able to ease my anxiety surrounding dental treatment. The new Austin Friars premises is so well located in the heart of London and it’s actually a tranquil experience to attend appointments.100% recommended!

George and his team have been looking after me for almost 10 years now. When George took me on, my teeth were in a very sorry state. Since then George has worked very hard to improve the function, health and look of my teeth. Thanks to George I only require routine checkups and the odd piece of work now. Seeing George has made going to the dentist a breeze and a very happy social occasion! I can’t recommend George highly enough. The best dentist I’ve ever had. Very attentive and caring…with exquisite attention to detail; second to none. I should also mention that the new location in Austin Friars is a lovely calm oasis in the heart of the City. Modern health setting in a historic built environment. Thanks George.

I had a tooth that was causing me severe pain. I was feeling highly anxious because my previous dentist treated the wrong tooth. My childhood orthodontist left me with an occlusion and had taken out too many teeth. I was having trouble finding a dentist who would not only treat my gaps and cavities, but would also provide an unbiased opinion of my previous treatments. After appointments with other clinics, I found Cap City Dental. Dr Druttman, Marilou, Reni and Michael were welcoming. They helped me correct years of problems in just three visits over as many weeks. The team genuinely try to understand what you are trying to achieve. They don’t push you to have work done. I particularly appreciated Dr Druttman’s comprehensive reports in which he provided his professional opinion on what happened and what should happen moving forward. I highly recommend them not only because they make sure you feel comfortable, but provide you with enough information to ensure you can make an informed decision.
