This question tends to get asked a lot as people really know about the bleaching tray method but little about laser teeth whitening as it is newer and not as established.

Over the course of a few years our change start to change colour and this is due to several factors. Mainly the lifestyle we have will influence a lot of the tooth's changing of colour so things like red wine, our favourite coffee from Costa or maybe its heavy sauces like pasta or spices like curry or chilli that is doing the trick and trying to change our lifestyle to accommodate our diets and lifestyle is just about impossible.

Another factor is the type of enamel and the thickness as this will also increase the yellowing of the teeth. If we have very porous type teeth then they will stain quicker and also if you have thinning enamel than the average again this will reduce the time.

Ever way they is little we can do about the things listed above but consider a flexible and safe way to whiten teeth and this is where the laser method comes in to its own. The light will enable the treatment to happen in around one hour and with instant results this is the quickest and least hassle method to whitening the teeth.

For professional and busy people they want this instant approach and it will always work as there will always be staining in the teeth to extract and whiten and this just save a whole lot of time.

The alternative is the bleaching trays and these are made specially to fit the mouth by a dentist and then you will need to sleep in them for fourteen nights and the whitening process is gradual and accumulative. Many people find out that sleeping in the trays effects their sleep and then they stop using them quite quickly. Another problem is that during or after teeth whitening you need to avoid those well known staining components and this is quite challenging with the trays as you need to avoid the things you love for two weeks compared to just seventy two hours with the laser method.

The mechanics or method of whitening is very similar and the results will be similar but because of practical challenges the laser simply is quicker and easier to get the results you desire. With bleaching trays you are required to undertake the whitening program yourself whereas with the laser you walk in to a teeth whitening clinic and then you walk out later the same day with whiter teeth.

The laser whitening has become very popular and now a lot of the dentists are using a similar system called zoom whitening which is a light based system and with laser and zoom whitening there are plenty of videos to view on you tube showing the treatment being performed and the brilliant results achieved.

Always maintain good dental health and do not substitute this for whiter teeth!
