Tengo mal aliento aunque me cepillo bien: ¿qué está pasando?

I have bad breath even though i brush properly: what’s going on?

Persistent bad breath can be frustrating—especially when you brush every day, use mouthwash, and try to maintain good hygiene. If you’re doing everything right and still notice a foul odor, it’s time to look deeper.

Chronic bad breath, also known as halitosis, often has underlying causes that go beyond brushing. Here’s why it happens and how to solve it effectively.

Common causes of persistent bad breath

Good oral hygiene is essential, but not always enough. These are some common reasons for ongoing bad breath:

  • Coated tongue: The tongue traps bacteria and food particles that produce odor if not cleaned regularly.
  • Tooth decay or dental infections: Deep cavities, abscesses, or infections can cause constant bad odor.
  • Gum problems: Gingivitis and periodontitis release strong-smelling compounds from beneath the gumline.
  • Dry mouth: Saliva helps keep the mouth clean. When there isn’t enough, bacteria multiply more quickly.
  • Diet: Foods like garlic, onions, or coffee can cause lingering bad breath—even hours after consumption.
  • Digestive issues: In more complex cases, bad breath can originate from the stomach or digestive system.
  • Tobacco: Smoking dries out the mouth, alters oral flora, and leaves a persistent odor that’s hard to mask.

What you can do to fix It

  1. Brush your tongue daily using a scraper or your toothbrush.
  2. Don’t skip flossing, as food particles between teeth can also smell.
  3. Stay well-hydrated throughout the day, and avoid drinks that dry the mouth like coffee or alcohol.
  4. Visit your dentist to rule out cavities, tartar buildup, infections, or gum disease.
  5. Review your diet, and avoid strong-smelling foods if you know they affect you.
  6. Consult a doctor if bad breath continues—there may be a systemic cause.

Diagnosis is key

Many people try to cover bad breath with mints, gum, or mouthwash, but that only hides the problem. The most important step is to identify the root cause.

At Beamann Hobbs, we perform a full evaluation to detect the source of bad breath and offer the right treatment. From professional cleanings to gum therapies and restorations, we help you recover freshness and confidence.
