In-clinic teeth whitening: a brighter, more confident smile
How in-clinic whitening works, whether you need a second session, how long results last, and who should have a check-up before starting.
Dreaming of a whiter, brighter smile? With modern in-clinic whitening, getting whiter teeth is easier than it has ever been.
Teeth whitening is a non-invasive cosmetic treatment that aims to remove the stains and discolouration that build up on teeth from coffee, tea and other coloured drinks, from smoking, and from some of the changes that come with age.
How is teeth whitening done?
Whitening is done in the clinic with professional agents made for lightening teeth. They reduce staining and lighten the natural shade of the teeth.
The session is carried out under the dentist's supervision, with the gums and the tissue around the teeth protected so the treatment is safe and comfortable.
Will I need more than one session?
Teeth respond to whitening differently from person to person, depending on the teeth themselves, how stained they are and their original shade.
Some people get a result they are happy with from the first session. Others need an additional session to reach the shade they want.
Whether to repeat the session can be assessed 14 days after the first one, once the teeth have been examined and the shade you want has been confirmed.
Our aim is the best lightening we can achieve while keeping your teeth healthy and sound, not simply the fastest route to white.
Does whitening hurt?
Teeth whitening is a safe procedure when it is done correctly and under a dentist's supervision.
Some people feel temporary sensitivity during or after whitening, and it usually fades within a day. The dentist assesses your teeth and chooses the approach that makes sensitivity less likely.
How long do the results last?
How long the results last depends on your lifestyle and how you look after your teeth day to day. You can keep your smile bright for longer by:
- Brushing your teeth regularly, twice a day.
- Cutting down on coffee, tea and coloured drinks.
- Avoiding smoking.
- Keeping up regular check-ups and cleanings with your dentist.
Is whitening right for everyone?
Whitening suits many people, but it is best to have your teeth and gums examined before starting treatment.
It may not be suitable in some cases, such as untreated decay, inflamed gums or severe sensitivity. Fillings, crowns and other restorations also do not change colour with whitening the way natural teeth do.
