Is Coffee Bad for Teeth? Here is What You Need to Know

Although coffee has many benefits, drinking too much can leave a lasting mark on your smile. Dr. John Russo explains how coffee can be bad for your oral health.

• Tooth staining: Have you noticed your teeth are no longer as white as you’d want them to be? If you are a coffee lover, coffee could be one of the reasons your smile has lost its natural vibrancy. Coffee contains tannins (polyphenols) that can cause yellow or brown stains on your teeth. These compounds stick to the enamel, and regular coffee consumption can lead to noticeable discoloration. Luckily, coffee stains don’t penetrate too deep and are easily removable with dental cleanings and teeth whitening.
• Enamel erosion: Coffee is naturally acidic, and repeated exposure to acid can weaken tooth enamel. When enamel erodes, your teeth become more vulnerable to cavities, sensitivity, and further discoloration. Even the latte’s creamy, smooth texture may mask its acidity, but it’s still there, quietly affecting your enamel.
• Dry mouth (xerostomia): Coffee can reduce saliva production, especially if consumed in large quantities. Saliva is crucial in washing away food particles and neutralizing acids. A dry mouth increases the risk of tooth decay, bad breath (halitosis), and periodontal disease.
• Sugar: We all know sugar isn’t good for your teeth. Many people add sugar, flavored syrups, or creamers to their coffee, which feed harmful bacteria in the mouth. These bacteria produce acids that erode the enamel and increase the risk of gum disease.

Although coffee isn’t good for your teeth, it doesn’t mean you must give up your beloved latte! Simple habits can minimize the impact on your teeth:

• Drink it in one sitting: Sipping slowly throughout the day exposes your teeth to sugars and acids for longer periods. Dedicate 30 minutes to sip your coffee instead of doing it for hours.
• Use a straw: A straw helps bypass your teeth, reducing direct contact with sugars and acids.
• Rinse with water afterward: Swishing water in your mouth after drinking coffee helps wash away lingering sugars and acids.
• Brush your teeth: Brush your teeth to remove any coffee residue. However, wait 30 minutes before brushing your teeth after enjoying your coffee to avoid brushing softened enamel.
• Replace coffee with tea: While black tea has similar staining effects as coffee, you can try green tea, white tea, and other types of tea.

Coffee isn’t the best beverage for your dental health. However, enjoying it in moderation and practicing good oral hygiene can help keep your smile and coffee habit intact.
