You get many over-the-counter products like

  • The Whitening strips
  • A Whitening toothpaste
  • Whitening kits, as a whole
  • Applications with paint-on-brush
  • Teeth whitening trays
  • Dentifrices

But, all of these, take longer to whiten the teeth. Because they damage the teeth’ enamel. Whereas, professional teeth whitening is better. It is professional treatment. As a result, the harmful effects are far less.

The above-mentioned products are good. But, you should use them only to maintain already whitened teeth. The professional teeth whitening cost for the whitening kits starts at a low price of £15. The professional teeth whitening cost for the trays cost about £400. Most of the other over-the-counter product costs are low and affordable. But, the effects are not long-lasting.


Now, professional teeth whitening has its own drawbacks. Such treatments damage the teeth’ enamel. And, they increase teeth sensitivity. Plus, the treatment results last only 3 years. After which, you need a redo.

Following this, you should be equally aware of another factor. Repeated teeth whitening treatment is detrimental to your teeth’ health. And also, you cannot always invest in professional teeth whitening cost, repeatedly.

So, the easiest solutions are 2. One, treat before the staining of the teeth deepens. Two, avoid having too much coffee, tea, cigarettes, or other edibles that stain your teeth.

Anyways, if you finally decide to go for a professional teeth whitening, do make a survey for a good clinic and reputed doctor. So that, you get quality treatment and long-lasting results.
