How can I make my teeth look whiter?

I don't want to use whitening treys unless that's all there is. A friend told me baking soda helps get rid of stains on teeth so they look whiter as well as peroxide, is that true? What else gets rid of teeth stains and plaque other than whitening toothpaste?

Teeth Whitening At The Dentist You will need to visit the dentist at least once, and perhaps several times over a period of a few days to achieve maximum whiteness. The cost of whitening performed by your dentist will cost on average $650 each visit. It should take no more than one hour per session. Depending on the number of sessions required, the total cost could be well over $1000. The good thing about whitening at the dentist is that the results are almost immediate. You can leave the dentist's chair and have teeth 4 to 6 shades whiter. How it works is that the dentist will first clean your teeth, then protect your gums with a special shield or gel before applying the bleach to your teeth. After leaving the bleach on your teeth for 15 to 20 minutes, the process is then repeated a few times. A laser light may also be used to enhance the whitening effect.

Teeth Whitening At Home Teeth whitening in the comfort of your own home is a lot more convenient and also more affordable than dentist whitening. There are two main variations of take-home whitening kits. Ones you can buy from the dentist, and over-the-counter kits bought from stores or conveniently online. The kits sold by your dentist have a higher concentration of peroxide and cost more than over-the-counter kits. Take home kits from your dentist range from $100 to $400. Over-the-counter kits or those purchased online are around the $20 to $100 mark. They are both applied to your teeth in similar ways. A whitening gel is used in conjunction with a mouth tray which fits to your teeth. Some over-the-counter kits may also make use of strips which you stick over the top of your teeth
