What Causes Bad Breath Even After Brushing?
Bad breath can have many causes, ranging from too much garlic in a meal to a serious medical condition. This wide range of possible causes can make it difficult to determine the actual source. Bad breath can also be concerning when daily brushing and mouthwash do not seem to help. Below is more information on the numerous possible causes of bad breath that will not go away, even after brushing. These details may help you determine what may be responsible for the bad breath you are experiencing.
Possible Causes of Bad Breath
The wide range of potential causes can make it difficult to determine the exact source of bad breath. Here are a few of the most common causes and signs to look for:
- Poor oral hygiene: Neglecting your daily brushing and flossing routine can allow plaque and bacteria to accumulate on the teeth, causing a foul smell to come from your mouth. Food left stuck between your teeth may also rot and contribute to your unpleasant breath smell.
- Gum disease: When oral health is not properly maintained for some time, gum disease may develop. In this condition, the gums become irritated and inflamed and may recede from the teeth, creating pockets. These pockets can fill with bacteria, which may cause an odor on the breath. Signs of gum disease include red and irritated gums that appear to pull away from the teeth.
- Vomiting: Vomiting, whether from a short-term illness or prolonged sickness, can cause bad breath. This may be exacerbated by dehydration, which occurs with vomiting. Dehydration reduces saliva production in the mouth, and saliva plays an important role in cleaning the mouth and reducing odors.
- Sinus infections: Sinus and respiratory infections caused by bronchitis, viral colds, strep throat, or other illnesses can cause bad breath due to trapped bacteria in the nose and throat. Other symptoms of sinus infections may include nasal drainage, a runny nose, and a low-grade fever.
- Gastroesophageal reflux disease (GERD): GERD occurs when the stomach acid flows backward into the esophagus, causing irritation to the esophageal lining, discomfort, and bad breath. Individuals with GERD may experience heartburn, a lump-like feeling in the throat, and mild reflux.
- Bowel obstruction: One of the most serious causes of bad breath may be a bowel obstruction. A blockage in the large or small intestine can cause food to become trapped in the digestive tract, which may emit an odor similar to rotting food. A bowel obstruction is a serious medical condition that requires immediate attention. Additional symptoms may include severe bloating, abdominal pain, nausea, and vomiting.
When Is Bad Breath Concerning?
To determine the best treatment for bad breath, it is important to first identify the root cause. Fortunately, many cases of bad breath are caused by short-term and treatable conditions like poor oral hygiene, temporary vomiting, sinus infections, or GERD. When treated, the bad breath will often resolve within a couple of weeks. In more serious and concerning cases, persistent and foul-smelling breath may be a sign that immediate medical attention is needed. Early diagnosis and immediate treatment are critical. If you notice additional symptoms along with bad breath, such as severe pain, persistent vomiting, or other concerning issues, you should contact a healthcare professional immediately.
