4 years a customer and always professional yet friendly service. Corrected my major issues (fillings/caps) and while they're keen to ensure ongoing 'perfect teeth' they don't hard sell peripheral / optional treatments. Highly recommended

I was looking for somewhere with a personal touch, that I could trust and that’s what I got at Mint. They always remember my name and are so polite. After a year of zoom meetings I really wanted my teeth to be straight and the results completely surpassed my expectations. I now feel comfortable taking photos! The team explained everything clearly (I felt I could ask anything multiple times) appointments were always organised and it was a really easy, worthwhile process. My teeth look like my teeth but are now at their best.

The clinic is a really lovely place to visit - it is extremely clean and all of the staff are very friendly. They were kind and reassuring all the way through my Invisalign treatment - as well as having amazing technology at their disposal. Dr Imran is so accommodating and kept everything simple, addressing any concerns straight away. All in all I would definitely recommend Mint Dental Clinic, a lovely experience all round.

Over the past six years Dr Raj and Preanka and all of the team at Mint have been exceptional. Every member of the team is exemplary at their expertise and I've never felt in better hands at the dentist. Affordable and top of the range, I would recommend them to anyone.

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.

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.

The Cost Of Tooth Whitening

For our patients near SE1, Mint Dental offers two types of teeth whitening: in-practice whitening carried out by a professional dentist and at-home teeth whitening kits.

We use special light-accelerated bleaching technology for teeth whitening applications that can give instant, long-lasting results in just one appointment. See laser tooth whitening options.
