There's more to healthy teeth than appearance, but you might be uncomfortable showing your teeth if they've yellowed over time. Many people have turned to teeth whitening systems to restore their smiles and confidence. If you are considering this process and want to learn more about how it works, here is a guide to this tooth brightening treatment.

What to Know About Teeth Whitening 

How Whitening Treatments Work

A whitening agent, either hydrogen peroxide or carbamide peroxide, bleaches surface stains on the enamel surface of your teeth. Although there are a variety of methods, teeth whitening is most effective and long-lasting when administered by a professional. Hydrogen peroxide can reach below the enamel and penetrate the dentin layer, affecting the collagen proteins. Always follow your dentist's recommendations for the healthiest approach to achieving a brighter smile. 

The Best Candidates for Teeth Whitening Treatments

People with healthy teeth and gums experiencing yellow discoloration have the most success with whitening treatments. Whitening agents are not effective for veneers, crowns, or fillings, nor for discoloration from tooth injury or medication. Tooth sensitivity doesn't prevent you from lightening your smile, but it can make it uncomfortable. Consult your dentist for the best course of action for you. 

How to Prevent Discoloration

Whether you've just had your teeth whitened or you want to keep your smile bright, be proactive by avoiding food, drinks, and other habits that accelerate tooth discoloration. Red wine, tea, and coffee are dark in color and stain your teeth over time. Smoking and tobacco are notorious for casting a dark hue that can be very difficult to eliminate. If you can't avoid dark food and drink, rinsing immediately after eating helps eliminate staining residue. Maintaining preventative measures like flossing, brushing, and regular cleanings is the best line of defense to keep your smile bright and healthy.
