If you're wondering how to whiten your teeth and how teeth whitening gels work, you're not alone. Yellowing, stained teeth are fairly common. Over-the-counter whitening gels or a gel provided by your dentist can help make your teeth appear lighter. With the guidance of your dentist, you can safely and effectively brighten your smile at home using a teeth whitening gel.
It's natural to be curious or concerned about what's in dental whitening gel and how it works. Whitening gels have bleaching ingredients and are safe for most teeth. Most gels contain hydrogen peroxide and several other added ingredients to improve the product's performance and flavour.
