Why do you rarely see a movie star with bad teeth? It is because it is such a prominent feature and the sight of a beautiful smile is very engaging. A great smile can hugely influence a first meeting with someone, whether it be in your personal or professional life.

Firstly let me explain the reason why dentists charge so much for teeth whitening – Because dental whitening machine is very expensive. Dental offices apply a huge product mark-up to cover their overheads; facilities, equipment, staff, time, administration, etc. It really is as simple as that. When you order your coffee at Starbucks, an extra charge is applied for drinking it in one of their shops rather than taking it away. Its the same principal, but the mark up for whitening is much higher.

So back to the question, are the kits safe. I will give you a few pointers on choosing where to buy from. Firstly, once you have searched the internet for suppliers and are comfortable with a certain site, take a look and see if they have a good amount of information about their products and most importantly, make sure their kits come with an instruction manual. On this manual should be steps on how to apply the product but also what is contained.

Home teeth whitening kits that use strips which are adhered to the teeth for a short period or even overnight can whiten on contact when the strips are used. These strips are cost effective and some of the cheapest available on the market and can be used for a long term period with very little side effects. As a disadvantage to using home teeth whitening strips means that portions of the teeth may be overlooked throughout the whitening process if your teeth are not perfectly aligned. In some cases, the strips may not adhere well to the teeth and be difficult to remove if kept on too long. Be sure to consider all advantages and disadvantages before using teeth whitening strips and dental handpiece.

At home whitening trays can be messy to use, but by far yield the best results possible when it comes to whitening at home. These trays are available for prices between thirty and fifty dollars for a course of treatment through three to five days and can be easy to use. Since the trays encompass the front and back of the tooth, the whole tooth is exposed to the bleaching mixture which can increase the effectiveness of the white trays. Although these trays may cause mild irritation to the gums and areas of the mouth, they offer the best bang for your buck when it comes to at home tooth whitening.
