All of us would love to have that perfectly white smile that you see many celebrities with but how easy is it to achieve? There are so many products out there that promise whiter teeth in just one or two applications and many toothpastes are advertised as whitening. You may think that spending a couple of extra pounds in a whitening toothpaste is worth it but does it actually really make a difference? Some of these products can help remove surface stains caused by coffee, tea or smoking for example, but they cannot change the natural colour of the tooth or remove stains that are deeper than the surface. Often a good toothbrush with toothpaste on is an effective as any whitening toothpaste. Activated charcoal can work well to remove stubborn stains but it is an abrasive so you need to be careful not to over use it as this could damage the protection layer.
If you really want to have noticeably whiter teeth then you need to have a proper treatment ideally done by a qualified dentist. It will set you back a few hundred pounds and will eventually need doing again but can give you that brighter smile you have been looking for.
