If you enjoy drinking tea, then you may already know that it is rich in tannins. Not to be confused with tannic acid, tannins are substances known as phenolic compounds. Especially abundant in black teas, tannins have a number of effects on the oral cavity. Here are some ways tannins from tea can affect your teeth and gums.
Acid Erosion
Also found in red wine, tannins in black tea can lead to acid erosion. This causes your dental enamel to weaken as a result of thinning. Strong dental enamel is your first line of defense in the prevention of cavities and dental abscesses. Healthy dental enamel helps prevent cavity-causing bacteria from getting inside your teeth; however, when the integrity of your enamel is breached as a result of tannins, orange juice, or coffee, you may be prone to dental problems.
If you are a heavy tea drinker, see your dentist on a regular basis. He or she will monitor the condition of your enamel, and if signs of erosion, such as yellow discoloration, cracks in your enamel, or tooth sensitivity upon probing with dental instruments, are present, a treatment plan to strengthen your enamel will be implemented. During your treatment, your dentist may recommend that you cut down on your tea consumption as well as your consumption of coffee and citrus juices.
Tooth Stains
Tannins can also cause significant staining of your teeth. While the tannins themselves do not significantly contribute to dental staining, they can attach themselves or bond to other highly pigmented foods and drinks, making them more likely to stain your teeth.
To reduce your risk for staining after drinking a cup of tea, rinse your mouth with plain water so that the tannins do not adhere to your teeth. Also, a tooth-whitening toothpaste will help keep stains to a minimum; however, professional dental cleanings are your best treatment option for minimizing tooth discoloration.
While tannins can raise your risk for enamel erosion and dental stains, they may also have a positive effect on your oral health. Tannins possess potent antibacterial properties and, because of this, may reduce your risk for gum disease and oral infections.
If you are a habitual tea drinker, be sure to see a dentist on a regular basis. He or she will monitor the status of your enamel very closely for signs of erosion and will suggest a treatment plan if thinning or yellow discoloration is noticed. When your enamel gets thinner as a result of erosion, your dentin will be visible, which is typically yellow in color.

Hello, my name is Jeremy Richards. Welcome to my site about dental care. I recently had to live with a severe cavity for several months while seeking out a qualified dentist. Since I was between insurance coverage plans, I had plenty of time to explore my options. When I could finally see the dentist, the tooth decay had advanced to a serious stage. The dentist used his skills and expertise to remove the decayed material and close up the hole for good. My site will cover information about selecting a dentist, going through procedures and caring for your teeth. Please visit often to learn more.
