Having a morning coffee to start your day, or a midday coffee to keep your day going, is the best feeling. It energizes you and helps you get through the day. But have you ever noticed how you are left with sour notes in your mouth and a foul smell. Does that mean you have bad hygiene or is it an indicator that you should not be having coffee? The answer is neither, it is due to some compounds in the coffee. You may have noticed that this is the case with many other strong-tasting foods like garlic, onions, boiled chicken and other dairy products. The Mayo Clinic explains that food particles breakdown around your teeth leads to more bacteria and causes a bad smell. These foods enter the blood stream after you ingest, get carried to your lungs and affect one’s breath. While it may seem like a minor issue, it can be noticeable to others and make us feel self-conscious. So, it's important to understand why coffee causes bad breath and what we can do to get rid of it. Why Does Coffee Make Our Breath SmellWhen coffee beans are roasted, they release certain chemicals that contain sulfur. According to MedlinePlus these sulfur compounds are a big reason why coffee makes your breath smell bad. Think of it like the smell of rotten eggs, but much milder. Coffee is also acidic, which means it can change the pH balance in your mouth, making it easier for bacteria to grow. When bacteria grow, they release even more smelly sulfur compounds. On top of that, coffee can dry out your mouth. Caffeine acts a little like a dehydrating agent, and coffee also contains tannins, which stop your mouth from making enough saliva. Saliva helps wash away bacteria and food particles, so when your mouth is dry, these things stay around and cause bad breath.How To Fix This Issue?The best way to avoid coffee breath is to make some smart choices about how you drink your coffee. Experts suggest drinking black coffee, without any milk or sugar, is better for your breath. Milk and sugar can feed the bacteria in your mouth, making the smell worse. If you must add flavor, try stirring your coffee with a cinnamon stick or a vanilla bean. These natural flavorings can add a nice taste without causing bad breath. If you need a sweetener, try using sugar substitutes instead of regular sugar. If you have to use dairy, whole milk or half and half are better than skim milk, as skim milk contains more sugar.If you're willing to try something other than coffee, there are some good alternatives that can still give you a caffeine boost. High-caffeine black tea or chai tea can provide a similar pick-me-up without the strong coffee smell.Whether you drink coffee or not, good oral hygiene is essential for fresh breath. The sulfur compounds, acidity, and tannins in coffee can all contribute to bad breath. So, it's important to brush your teeth twice a day, floss regularly, and use mouthwash. If you drink coffee, you might need to pay extra attention to your oral hygiene
