Bad breath is one of the most common and embarrassing problems. Many people suffer from it even though they brush their teeth daily. Dr. Ehab Fouad Eskander, Specialist in Oral Surgery and Dental Implants, explains that the cause may not lie solely in the teeth but in several other overlooked factors.
Bacteria on the Tongue
The tongue has tiny papillae that can trap bacteria and food particles. This buildup may cause unpleasant odors that brushing alone cannot remove. Dr. Ehab Fouad Eskander recommends using a tongue cleaner daily.
Dry Mouth
Reduced saliva flow allows bacteria to grow, especially during sleep or due to certain medications. Dry mouth is a major contributor to bad breath even with proper hygiene.
Gum Problems
According to Dr. Ehab Fouad Eskander, chronic gum inflammation or bleeding gums can release unpleasant odors, regardless of regular brushing.
Tooth Decay or Old Fillings
Hidden cavities or leaking dental fillings may harbor bacteria, leading to persistent odor.
Non-Oral Causes
Some health conditions, such as acid reflux, sinus infections, liver disease, or diabetes, can affect breath odor. Dr. Ehab Fouad Eskander emphasizes considering these during a full diagnosis.
If bad breath persists for more than two weeks despite proper brushing and tongue cleaning, it’s advisable to consult a dentist.
Dr. Ehab Fouad Eskander performs a thorough examination of the teeth, gums, and tongue and may request further tests or refer the patient to a specialist if internal causes are suspected.
