Which Tooth Whitening Method Is Best?

Of course, this will depend on how many shades you want to lighten your teeth and the current condition of your oral health. But the benefits between the two treatments can quickly become obvious regarding longevity and whiteness, which you can see in the table below.

Regardless of the type of tooth whitening you are recommended, choosing to whiten your teeth with a dentist will produce better results and be more cost-effective at the same time. 

Agents like peroxide found in tooth-whitening kits in shops like Boots use lower concentrations, which will not be able actually to alter the shade of the tooth.

I chose Mint Dental Clinic after searching for various dental clinics offering sedation and I had an incredible experience thanks to the entire team!! I am terrified of the dentist with a phobia of needles, and I avoid going for check-ups to the point where I developed a huge amount of cavities. After my teeth were analysed by Dr Patel's team, they identified that some of them needed urgent fillings. As sedation is expensive, the team was helpful and patient in helping me figure out the right financial plan to tackle everything before my teeth worsened, including adding extra teeth cleaning for free! I had IV sedation twice for two rounds of fillings across a month, and each time I was put at ease despite coming in the clinic with intense anxiety. I cried as I sat in the chair with the IV in my arm due to my fear of needles. They were kind and patient, and the nurses / sedationists helped calm down my breathing despite the panic. I was terrified of being 'awake' but not being able to communicate or breathe. The team was very reassuring in those fears and I had a lovely experience where I remained conscious but with amnesia, so I had 0 trauma afterwards since you have no memory of anything! The team made me feel heard and supported without being judged. They made sure my chaperone knew everything before bringing me home, and all of my teeth are healthy without any complications post-appointment. I am now ready for routine work without the intense fear of dentistry and feel much more ready to start any dental work WITHOUT sedation in the very near future!

The whole team at Mint, starting from the moment you walk through the door (or call up) are focused on providing excellent care. Great reception team and Orman especially, always goes that extra mile. My dentists (Dr Mehdi and Dr Alves) are very personable, thorough and ensured everything was explained clearly, and only proceeded once I'd understood and was content. Whilst in the chair, both dentists were checking in making sure I was doing ok throughout it all. Then at the end, checked I was happy and offered an open-door to return, for some tweaks if necessary. I am very happy with the results. I always feel completely at ease for my visits, so much so that I look forward to them. Highly recommend! >

I’ve had an outstanding experience at this clinic. Dr. Raj Patel delivers exceptional quality work and somehow makes every treatment feel completely painless. It’s amazing having all types of dental care under one roof, and the whole team really focuses on prevention rather than quick fixes. After completing my treatment, I now have a healthy, confident smile that still looks natural. The hygienists are fantastic, and every member of the team is warm, professional, and genuinely invested in your wellbeing. If you’re looking for shortcuts, this isn’t the place for you—but if you want thorough, honest, high-quality dentistry, I can’t recommend this clinic enough.

I’ve had an excellent experience at this dental practice. My hygienist Peter is absolutely brilliant, thorough and incredibly skilled at what he does. He always takes the time to explain everything clearly and makes each visit comfortable. A big shout-out as well to Arman at reception. He’s always friendly, helpful, and efficient, making the whole process from booking to check-in smooth and stress-free. Overall, a fantastic team and a dentist I truly trust. Highly recommend!

I inquired about Invisalign's earlier this year at this clinic, as I was quite self conscious of my teeth. I had a very insightful conversation with Arman who gave me a thorough explanation regarding the process, treatment, what to expect results wise, and the cost. This then led me to begin my Invisalign journey, and from start to finish it has truly been seamless, immensely effective, and so beneficial. Dr Sharma did an exceptional job throughout, and helped in understanding the developments to expect, how it occurs, and overall making my experience extremely easy and efficient. The service was immaculate from the receptionists, Dr Sharma and his assistant dentist. Also as of recent, I’ve been getting hygiene checkups by Danica and I must say she has been amazing. She explained the anatomy of my teeth and gums in detail, and made me understand much more about dental hygiene and its cruciality. Overall I have no complaints whatsoever, and will 100% refer this clinic to friends and family, as they produce and prioritise high-quality work and service. Extra shout out to Arman as he’s been extremely helpful, and looked after me very well.

I highly recommend this dentist. Dr Patel is an exceptional professional, and my family and I have been attending for many years. Since we moved to the Clinic, even my son, who never liked going to the dentist, now looks forward to his visits. The dental hygienist is also excellent. The reception team provide consistently high service, always polite, welcoming and professional.

Professional teeth whitening guide

Why are my teeth yellow?

Teeth tend to lose their whiteness with age, but lifestyle habits like smoking or drinking lots of products like tea, coffee or red wine can wreak havoc on the luminosity of your smile.

Hence, it is often important to seek professional advice from a dentist who can identify which treatment will be best for targeting yellow teeth or tooth discolouration.

  • Fluorosis: Instrisinc staining caused by overexposure to fluoride in the first eight years of life.
  • Age: As we age, the tooth’s composition changes, which also causes the intrinsic staining of teeth.
  • Hereditary: Imperfections in the enamel or dentin often cause tooth discolouration.
  • Lifestyle: Habits like smoking can cause teeth to be yellow much more quickly (extrinsic staining).
  • Trauma: When a tooth experiences trauma, the pulp becomes necrotic and stains the dentinal tubules black. In these cases, internal bleaching will only be applicable after a root canal.
Will tooth whitening work?

The success and recommendation of tooth whitening agents highly depend on the staining present.

For example, regular tooth whitening products cannot effectively target intrinsic staining. In comparison, extrinsic staining refers to superficial stains that affect the surface of the teeth. Sometimes, these stains can be better targeted with dental prophylaxis or hygienist therapies.

How long does tooth whitening take?

It will depend on the type of system you choose. Typically most treatments take two to three weeks to work, or results are instant with laser teeth whitening options.

How much whiter will my teeth be?

We can lighten teeth up to 18 shades. However, most cases can expect their teeth to be lighter by 5-7 shades.

How long will the effects of whitening last?
  • Teeth can remain whiter for up to three years and long-term with regular top-ups.
  • What should I avoid after having my teeth whitened? Avoid staining products like tea, coffee and wine to ensure your smile dazzles for longer.
Is the treatment safe? Does it hurt?

The treatment is safe and pain-free – however, as explained below, some sensitivity can be experienced.

Are there any risks to be aware of?

The most common side effect of tooth whitening is sensitivity (gingival irritation). Only 25% of patients experience non-sensitive reactions, with the other 75% experiencing varying degrees. Therefore, if you are experiencing severe sensitivity, there are protocols in place to adapt the strength of your treatment.
