How to Extend the Results of Teeth Whitening

Do your teeth have a yellowish cast? Perhaps they look dull and have some discoloration. Discolored teeth can make you look unhealthy. You’re ready for a smile makeover. Teeth whitening can transform your smile so that you can once again smile with confidence, resulting in a healthier and younger appearance.

Dr. Nabila Mannan, board-certified general, cosmetic, and pediatric dentist with Rainbow Dental, provides you with options for teeth whitening, including custom trays made to fit your teeth that you can use at home.   

Why teeth become stained

Stained teeth are a result of a combination of environmental and genetic factors, including:


Having stained teeth or a yellowish cast to your teeth instead of “pearly whites” is an unfortunate byproduct of aging. Most older adults have some discoloration. The enamel on the surface of your teeth thins as you age, allowing the dentin, the layer under the surface of your tooth, to show through. Dentin becomes a yellowish color as you age. 

Foods and drinks you consume

Your lifestyle habits contribute to tooth discoloration. Some of the substances that can stain your teeth include the following:


The nicotine and tar in tobacco can stain teeth. Your teeth may have an unhealthy brownish or yellowish appearance. 


You might not be aware that some common medications can cause tooth discoloration, including antihistamines and blood pressure medications. 

Teeth whitening works 

Dr. Mannan provides you with options for teeth whitening, including an at-home system. She takes impressions of your teeth to provide you with custom-made trays that fit your mouth exactly. You will wear the bleaching trays for 30-60 minutes a day for a predetermined number of days. As you wear them, your teeth will gradually get whiter until they get to the shade you desire. You’ll begin to see results in two weeks once you’ve started.
