Teeth whitening and bleaching are terms that are used interchangeably when talking about whitening teeth. However, that does not mean both work the same way.
Teeth whitening is a term used to describe multiple methods and products that are used to brighten the teeth. Whereas bleaching is a type of treatment which specifically uses bleach to lighten the teeth.
Teeth whitening vs bleaching
Teeth whitening is a process used to brighten the teeth; this is done by applying a product which lifts stains. The chemicals used in whitening products tend to vary from practice to practice, the best way to find out what is used in your practice is to ask the dentist.
Whitening agents work by releasing oxygen molecules into the surface of the tooth, the oxygen permeates into the enamel and starts to react to the discolourations. The process occurs across the whole tooth and begins to lighten the colour of the tooth.
Teeth bleaching refers to the very specific treatment where bleach is applied to the teeth to lighten them. Bleach can react to the soft tissues in our mouth and on our face, the dentist will cover up these areas, to protect them from the solution.
Things you should know about whitening/bleaching
Areas which have been treated, like with a filling or crown, cannot be whitened. This can create uneven colouration across the smile. In some cases, the stains and discolouration on the teeth cannot be lightened or removed, which also can cause the teeth to be varying shades.
Using lemon juice and bicarbonate soda will only damage the teeth. Acids from any acidic fruits can eat away at the enamel. This is not going to whiten the tooth; it will weaken it. Some at-home whitening kits contain harsh chemicals, which if improperly applied to the mouth, can chemically burn the soft tissues of the mouth.
If performed by a professional, your teeth will not be damaged by bleaching or whitening them, they will remain healthy if proper hygiene is maintained.
Sadly, the results won’t last a lifetime. Our teeth are exposed to various things like pigments or trauma, which naturally have an impact on our teeth.
It’s advised patients avoid highly pigmented foods and drinks after receiving a whitening treatment. It is best to wait a 24–48-hour period to prevent any strong pigments from heavily staining the teeth.
What do we use?
At our practice, we utilise the Philips Zoom whitening treatment. That’s because it is reliable, as well as being quick and easy to use. The treatment is safe and effective, with results lasting between a few months to a year, depending on the quality of care.
We also offer at-home whitening kits, inside of these kits there will be tailored dental trays and whitening solutions. For these kits, we take digital impressions of the mouth to make a customised tray. This is then provided to the patient alongside the solution as well as giving instructions to its use.
