One of the most searched for questions is what is the best teeth whitening method, product or service to make the teeth really white in colour and brighten them from their current yellow state.

Teeth whitening has become a useful and necessary part of our lives because our teeth get so dis-coloured from the every staining we get in foods and drinks. This means they change colour and over a period of time get darker and darker and turn to a solid yellow colour or even brown if you smoke a lot.

The good news is that teeth whitening is an ideal and safe solution to re-whiten the teeth back to their former glory. What teeth whitening cannot do is make them whiter than their natural colour and for most people a natural looking smile is perfect.

Many experts would agree teeth whitening does not guarantee to work on everyone as there are a few people that the treatment would not whiten the teeth due to medication when they were younger but luckily these are minority and not the majority of people.

I think the best strategy if you are looking for the whitest smile when having teeth whitening is just to keep your expectations in check. Not everyone is going to look as white as celebrities teeth featured in fashion magazines or on the TV. The likes of P Diddy, j-lo and Simon Cowell all have veneers and these are much whiter than the natural tooth's colour so do not expect this outcome unless you have a very white coloured dentin.

The dentin sits beneath the enamel and will reflect through the colour of the enamel and this ultimately will control the colour and no teeth whitening is going to change this. Only having veneers over the top of the natural teeth can compensate if you want to change to a much dramatic white colour.

Best teeth whitening is more difficult to guess as you are not always comparing apples with apples. For example the Crest white strips work well but are never going to whiten the teeth as well as the bleaching trays many of the UK's dentists offer their customers. One option is around twenty pounds and the other option is over two hundred and more in some parts of the country.

If we are talking about what is the best on a small budget then the strips or mouth guards are worth investing in to see if they remove the staining on your teeth. Everyone's teeth are different so there is not a one method works for all treatment or service but if money is tight then start on these and if they do not work whiten the teeth as well as you hoped then look for a faster more powerful treatment like laser teeth whitening. This method works well on just about everyone and the results are immediate so no waiting a couple of weeks to see your new smile.

Always seek the advice of the dentist before embarking on your teeth whitening journey!
