Beat the stench: What bad breath really does to your health

Illustration - Man with bad breath
In rare cases, bad breath can be tied to acid reflux, the flu or having a bad cold.

You just finished your favorite dinner that had a lot of garlic and onion. You and your family notice right away the food has left you with bad breath.

Could it be just the smelly foods lingering while you talk? Or could it be more than a little bit of garlic?

“I do see patients with bad breath,” said Megan Ryan, D.M.D., a Marshfield Clinic dentist. “But it’s almost always related to oral hygiene.”

What causes bad breath?

Bad breath, or halitosis, can be tied to a number of factors related to poor dental hygiene.

“Of course it can be from eating foods like garlic or onion,” Ryan said. “But it could be more than just food. It can be tied to cavities and just poor dental health in general.”

Other factors include dehydration and smoking.

In rare cases, bad breath can be tied to acid reflux, the flu or having a bad cold.

If you have bad breath from cavities and they are left untreated, your bad breath can get worse and you could lose teeth or an infection may develop from failing to treat the cavities.

How to get rid of the stench

Ryan says anyone can get bad breath but there are some people who are more susceptible.

“It is very common in people who smoke or people on a lot of medications, which can cause dry mouth,” she said. “So cutting back on smoking can definitely improve bad breath.”

To keep it under control, visit your dentist regularly, to make sure you don’t have cavities or an infection in your mouth. Brush your teeth and tongue, especially the back of your tongue where bacteria can build up.

Other tips include flossing once a day, using a mouth rinse and replacing your toothbrush regularly. If you still have problems, talk with your dentist.

    I get Dry mouth so bad that my tongue will actually start bleed and I'm drinking all day and it seems like I just can't get enough liquid to moisten my mouth. Some mornings I have woke up and my tongue has actually been stuck to my cheek or roof of my mouth and it painful trying to get in to position to get liquid in my mouth and I'm mostly just pouring water in and spitting it out until my throat is able to do the natural swallowing motion you said there is so medication that can be prescribed? I use the over the counter stuff and it like a 5minute shower in the desert. I know a lot of this is due to medication but I'm kind of between a rock and a hard place. I can't find a dentist around eau Claire that takes I guess it was called Badgercare I don't know what it is called now Security Health I believe Right now both sides of the corners of my mouth have torn because of this issue and it will just get worse now that winter is coming. Thank You for any advice you can give….. <3 is what this world needs now put hate down now 🙂

      Hi, Brigitte. I suggest you reach out to Chippewa Falls Dental Center, which serves all patients, regardless of ability to pay or insurance status. A dentist there will be better able to address your specific questions and concerns.

    Acid "reflex"….. No wonder half the nation says it wrong when the professionals don't know the correct term is "reflux". I'm not in medical field at all but I do pay attention!

      Hi Karen, Thanks for bringing this to our attention. We have updated this post to fix this misspelling. You are correct, the term is actually reflux. Have a nice day.

    There are a number of products out there that claim to help with dry mouth. I'm wondering if one brand is better than another?

    1. Teri Olson

      Nancy, I like the act lozenges. I am not in the dental field. This is just a personal preference. I know they have them at Walmart

      Hi, Nancy. I apologize for just getting back to you; I wanted to be sure I received an answer from an expert before sharing with you. Here is dentist Megan Ryan's response:

      From toothpastes and mouthwash to gum and candy, there are many options for dealing with dry mouth. While there is no one treatment or brand that I would recommend, there are some ingredients to look out for.

      Many types of mouthwash contain alcohol (“ethanol” on the label). This is what can cause that burning feeling when you start rinsing your mouth with mouthwash. Alcohol can cause some dryness so if you are trying to treat dry mouth, I would look for something without alcohol or ethanol.

      There are many types of gum or candy/mints that can also help with dry mouth, mostly via stimulating the salivary glands. With any gum or candy for dry mouth, make sure they are sugar free and be sure to drink plenty of water.

      There are a lot of great products on the market for treating dry mouth and I would certainly recommend trying a couple to find what works for you. As always, speak with your dentist about any issues with dry mouth as there may be options for treatment via prescription, as well.

      I hope Megan's answer is helpful for you. Thank you for reading. -Kirstie
