There are many contributing factors that can lead to the discoloration, staining, or yellowing of your teeth. Knowing what causes tooth discoloration can help you make lifestyle changes that may slow the discoloration process down or help maintain your bright, white smile after treatment.

Diet Matters

Leading tooth staining culprits include coffee, tea, and red wine. When consumed as a part of your daily diet they can cause yellowing of your teeth. The deep color pigmentation in these beverages stick on the enamel of your teeth causing yellowing over years of consistent consumption.


Dentin Exposed: Dentin is the area below the enamel of your teeth. When your outer enamel layer begins to wear away, the dentin layer is exposed. Yellow in color, exposed dentin will make your smile appear stained and yellow.

Dentin Buildup: Dentin may build up under your enamel layer when exposed to a trauma. Discoloration due to dentin buildup can cause dark brown spots to from below your tooth’s enamel. Tooth discoloration due to trauma, medication, or illness may be resistant to teeth whitening trays or Zoom Whitening. Dr. Tan-Chu offers a wide range of cosmetic dental procedures that can help whiten your smile if you have brown discoloration due to trauma.

Tobacco Use & Smoking

Nicotine and tar turns yellow when introduced to oxygen leaving yellow stains on your teeth. Smoking also increases your risk of gum disease and oral cancer. In just a short visit to our New York City dentist office you can have a rejuvenated, brighter, whiter smile. Regular brushing, flossing and routine visits to Dr. Jocelyn Tan-Chu can keep your smile whiter for longer. We also offer touch up trays for prolonged results.
