Some people love the taste of coffee or tea, but it can have negative side effects for your teeth. The darker color of both beverages can stain your teeth if you don’t rinse with water afterward. Coffee’s acidity can also contribute to tooth decay over time. Fortunately, there are ways to reduce staining by avoiding certain habits and taking preventative steps to keep your pearly whites healthy!

How Coffee Can Stain Your Teeth
A few factors can contribute to coffee staining your teeth. First, coffee is acidic and has a pH level of 5.5, which is more acidic than orange juice (pH 4), wine (pH 3) and soda pop (pH 2). The acidity makes the enamel on your teeth more porous so that stains seep into the enamel, leaving dark spots on your teeth.
Secondly, the tannins found in tea also contribute to staining because tannins are an astringent that causes tissues to contract or shrink when they come in contact with each other or something else (like your teeth). When this happens inside your mouth around bacteria or plaque build-up on your teeth it results in discoloration caused by oxidation from exposure to air and light over time as well as increasing risk for dental cavities due to decreased ability for saliva flow against bacterial growths when exposed continuously over weeks/months/years without proper cleaning habits.”
Enamel is the hard, outer layer of your teeth that protects the more vulnerable layer beneath.
Enamel is the hard, outer layer of your teeth that protects the more vulnerable layer beneath. It’s made up of a protein called hydroxyapatite and forms when you’re developing in utero, so it’s one of the last parts of your body to fully mature. It feels smooth because each crystal is small, but they’re tightly packed together to make enamel very strong.
Most people aren’t aware that they have enamel; it’s such a tough substance that we don’t even think about it until something goes wrong with it! When you get a crack or chip in your tooth, for example, you can see through this thin layer down into dentin—the yellowish tissue underneath—and know there’s something wrong with your tooth.
Enamel can be stained by coffee, but not just because it’s dark.
Coffee is not the only dark beverage that can stain teeth. Tea, red wine and cola also contain tannins and can stain your enamel. Tannins are found in the skins of grapes, berries and other fruits and vegetables, as well as tea leaves.
The same compounds that cause these beverages to stain your teeth will also stain your clothes if you drink them on a regular basis. If you’re concerned about your coffee-stained tooth, try switching to decaf or drinking more water during the day so that you don’t have time between cups of joe to sip on other beverages with high amounts of tannins like tea or red wine.
Coffee’s acidity can also contribute to tooth decay.
The acidity of coffee can also contribute to tooth decay. Enamel is the outermost layer of your teeth, protecting them from damage and discoloration by things like coffee, fruit juices and even soda.
When you drink coffee, that acid content causes the enamel to weaken and discolor over time. The more often you consume acidic foods or drinks like coffee, the faster this process happens—and if your enamel weakens too much from erosion caused by repeated consumption of acidic foods and drinks such as coffee (or maybe just one too many late-night cups), then it’s possible for cavities or other dental issues to result.
If you love coffee and tea, be sure to rinse with water after drinking!
To protect your teeth from the effects of coffee and tea, we recommend that you use a straw to drink your coffee and tea. This will prevent staining by keeping the liquid out of contact with your teeth.
If you don’t have time to rinse after drinking these beverages, it’s important that you at least brush your teeth soon afterward. If possible, using an alcohol-free fluoride toothpaste will help prevent staining by strengthening enamel and remineralizing tooth surfaces.
