Staining can happen over time to your teeth from eating certain foods and consuming certain drinks. Your smile is your own and it is not my intention to change that, but you do not want to attract attention one way or another with your teeth as a contestant. For information on ways to whiten your teeth, check out WebMD’s guide to teeth whitening methods below:

Here are some great resources that I recommend on information and products for teeth whitening:
If you are interested in professional level whitening results that last up to 12 months check out Crest 3D White Whitestrips With Advanced Seal Professional Effects Enamel Safe Dental Whitening Kit below:
If you are looking for a cheaper, more portable option, be sure to try out Teeth Whitening Pens by BrightTeeth Pro:
If time is an issue and you do not have 30 minutes to use the Crest Whitestrip trays, maybe consider Plus White Bleach Whitening Gel. You leave the gel on for 5 minutes and it whitens and brightens your teeth, by gently lifting away stains and reducing yellowing.
