There are many things that can discolor your teeth over time, and coffee is at the top of the list. It’s delicious, and millions of people feel like they couldn’t make it through the day without a cup or four.  If you’ve been drinking coffee for years, you may wonder how coffee drinkers can have whiter teeth. You could go to your dentist and begin a teeth whitening regimen with them that has you going into the office each week or more often and paying potentially over $1,000. You could get a take-home teeth whitening kit from your dentist, which may cost about $400. Or you could get an affordable teeth whitening kit by purchasing the CustMbite Smile Whitening Kit, which costs $30 for the original one-month kit, and $15 a month for refills of either the gel or the foam. You could also stop drinking coffee, but there’s plenty of good reasons not to go that far!
