Teeth Whitening

What Causes Tooth Discoloration

Teeth may be stained or discolored for many reasons. Generally speaking, foods and beverages that are more intensely colored tend to be the biggest offenders. Some examples would be coffee, wine, candies, berries, dark sodas, and tomato sauce.

In addition to color, acidity in foods and beverages can also stain your teeth, as acidic substances can erode dental enamel, which will soften your teeth and make them more vulnerable to discoloration.

Without proper brushing and flossing, a similar effect will be had. As plaque builds up on the surface and gum line of your teeth, it will begin to harden and turn into tartar, which uncovers that yellowish, bone-colored appearance on your teeth.

Teeth may become stained or discolored after trauma that causes the tooth to die. Teeth also darken as we age and this impacts different folks to varying degrees.

No matter what the cause of your teeth’s discoloration, The Happy Tooth can help you achieve the bright and beautiful smile you desire!

Regular Professional Cleaning and Polishing

The best way to keep your teeth bright and healthy is to have them cleaned and polished professionally at least every six months. If your teeth develop stains and deposits quickly, we might recommend more frequent cleanings.

In-office teeth whitening, such as Sinsational Smile, is a popular option if you’re constantly on the go. This is a 20 minute, in-office procedure using the first and only Green certified whitening system with less sensitivity than other in-office whitening options.

We also equip you with a take-home whitening kit to continue achieving your desired results.

Take-home teeth whitening trays come in various types and strengths. Some require a custom-made bleaching mouthpiece while others come with a one-size-fits-all tray. Take-home whitening trays allow you to conveniently touch up your teeth before special occasions without having to revisit your dentist.


Your dentist or hygienist will help determine which take-home whitening product is best for you.
