Your Dentist in Philadelphia Warns that Coffee can Stain Your Teeth

By Gerald Regni, DMD on January 05, 2015

If you always want to have a clean smile to flash, your Philadelphia dentist would like to remind you that coffee is one of the main perpetrators of teeth staining. Noelle Carver of eHow writes about the price that coffee drinkers need to pay in order to keep their pearly whites looking just that.

Many people can’t make it through the day without at least a cup of their favorite brew. Sadly, their teeth end up mocha-colored or even yellow after consumption. This is due to the tooth enamel (the white coating covering our teeth) having tiny holes in it that make up its texture. This enamel is made up of salt crystals, which can be bleached back to white the same way clothes can.

Why Does Coffee Stain Your Teeth

Food particles and drinks like coffee get into the holes in our enamel and stain our teeth over time. As we age the holes in our enamel grow larger, making older teeth easier to stain. The rule is that if the substance can stain clothes, it can stain your teeth.  So how do we combat this staining?


According to the American Dental Association, saliva builds and manages the healthy mouth, including teeth and gums. It naturally removes waste products, rinsing the mouth from acquiring microbial invasions that cause staining. Chewing sugar-free gum can stimulate the production of saliva.


Since coffee dehydrates, the coffee drinker is not able to produce enough saliva in the mouth to naturally rinse off the coffee particles. Make it a point to stay hydrated with water, and rinse after drinking coffee to help keep your mouth from going dry.


Everyone should brush at least twice a day--in the morning and evening--and ideally in the middle of the day. To prevent further staining, try brushing your teeth after drinking coffee. The fluoride in toothpaste mineralizes enamel, strengthening it and halting stains. If this is impossible, drink water to rinse the mouth or chew a stick of gum to trigger saliva production.

Remember: some DIY whitening treatments may cause teeth to turn blueish or damage them further. With that in mind, it’s best to seek professional help from an established Philadelphia dentist like Dr. Gerald Regni, DMD. Let such dentists guide you on your way to whiter teeth and soon, you’ll be flashing a million megawatt smile with complete confidence.
