If you are looking for options to whiten your teeth, whitening gels are good and safe, provided you choose the right product. However, if the stains have been there for too long or are too dark, or if you have previous crowns or fillings, it may not be very effective. So, always consult your dentist before using a gel. Read on to know more about teeth whitening gels.

Points to check before choose whitening gel
Firstly, do not choose products that are close to the expiry date. Whitening gels contain chemicals like carbamide peroxide, hydrogen peroxide, potassium nitrate, and amorphous calcium phosphate. Make sure that gel is packed well to prevent exposure of hydrogen peroxide to sunlight. Do not buy unpacked or loosely packed gels.
