The better contact that the bleach has with your teeth, the better the effects you’ll get from the whitening procedure.
Most over the counter tray systems use hydrogen peroxide instead of carbamide peroxide. Hydrogen peroxide is safe, but it doesn’t bleach as quickly. In most cases, if you’re using any at-home system, it will take several sessions a day for several weeks to achieve the same results that your dentist can get in his office in two-three ninety minute sessions. However, you?ll pay for the speed – a doctor’s office whitening treatment can cost you as much as $500 per session. An at-home system may cost as little as $30 for the total treatment.
Teeth Whitening Strips
A second popular method of whitening teeth is the use of teeth whitening strips. Like over the counter tray systems, the active ingredient in teeth whitening strips is hydrogen peroxide.
