Desparate to get your teeth whitened but scared it'll make your already sensitive smile even worse? Well despite popular belief it is actually possible, as we discovered when we put all of our questions on the matter to dentist to the stars Dr Richard Marques.

From where to even go for the procedure to how long it lasts, we've got all in the info you need before taking the plunge.

Is it even possible to get whiter teeth if they’re super sensitive?

Absolutely. Lots of my clients opt for the ‘Zoom’ in-clinic whitening treatment because it has adjustable intensity settings. Zoom can be customised to eliminate sensitivity and maximise comfort. 99% of people who opt for this experience little or no sensitivity.

Why does whitening make them hurt in the first place?

Bleaching agents in whitening treatments can get on the gums and soft tissue around the tooth which can cause some discomfort, but is easily looked after. The tiny holes or dental tubes within the layers of protective enamel on teeth can also expose the teeth to sensitivity when whitening agents leak through.

How long does the whitening last?

Depending on the treatment, whitening can last indefinitely if well maintained. Teeth will lose their sparkle if you smoke or regularly consume products that stain them i.e highly pigmented food and sugary drinks.

Will the process damage my teeth?

As long as you use safe, reputable treatments, your teeth should not be damaged at all. Enamel is considered the toughest tissue in the human body and whitening agents flow through tubules under the top layer of this to lighten stained tissue underneath. These tubules regenerate using saliva in the mouth, meaning your body works really hard to prevent any damage from teeth whitening – you just have to look after it!

Are at home treatments as effective as ones you have at the dentist?

I would always recommend consulting your dentist before using any at-home whitening treatments. Many professional treatments have an ‘at-home’ element, for example the ‘Enlighten’ program that we offer at the clinic uses trays and gels that are provided for treating at home following an initial whitening in the clinic.
