Do the Crest White Strips work just as well and as fast as bleaching trays from the dentist?

I am thinking of having veneers put on and I want my teeth to be the right shade before I have them put on. I really want to accompish all this in about 6 weeks is that possible? The color of my teeth arent very stained at all, I just need a couple shades brighter. Thats why I thought the white strips might work just as well as bleaching trays.

All whitening products contain peroxide either as Carbamide Peroxide (CP) or hydrogen peroxide (HP). Peroxide dissolves the organic stains in the tooth to change the color and produce a whitened effect.
There are four types of peroxide-containing Tooth Whitening products available:
* In-practice products are applied by a Dental Professional. These products contain a high percentage of CP or HP and are applied directly to the teeth. Some activated by heat, light, or laser. This may be the product for you if you're in a hurry for Whiter Teeth and you don't have tooth sensitivity. For very dark-colored teeth, the whitening process can be sped up in two to three hours followed by a take-home product until the desired whiteness is achieved.
* A take-home product supervised by a dentist is the most popular whitening method. These products contain a lesser percentage of CP or HP than in-practice products and are worn in a tray overnight or during the day at home. A custom-fitted tray is made to hold the whitening product directly against the teeth while lessening its contact with the gums. Some products have fluoride added to help prevent or treat mild tooth sensitivities. The typical stains of ageing will whiten in seven to fourteen days when the tray is worn overnight.
* Over-the-counter (OTC) whitening products contain a small percentage of HP or CP. Caution should be used with these products as many contain an acidic solution that can wear away tooth enamel. OTC products use a bulky, one-size-fits-all tray to hold the product. Usually more product is swallowed than stays in the tray because of the trays poor fit against the teeth. It can take up to six months and the purchase of several kits to get whiter teeth. Flexible strips coated with Whitening Gel have recently been introduced as an OTC at-Home Tooth whitening method. The strips are worn on the front teeth and folded over to keep them in place. Results are reported to be noticeable after fourteen days and effective for 6 months.
* Over-the-counter whitening toothpastes contain a small percentage of HP, CP, or polishing ingredient. The toothpastes are effective in keeping Teeth Cleaner and whiter looking but some may be very abrasive. The harsh abrasive will wear away the enamel with repeated use gradually making the teeth look yellow. Whitening toothpastes remove surface stains and prevent new stains from building up. Whitening toothpastes however aren't in contact with the teeth long enough to remove internal stains. Ask your dentist about the safety and cavity protection of specific toothpastes before you buy.
