Smell and taste belong to our chemical sensing system (chemosensation). The complicated process of smelling and tasting begins when molecules released by the substances around us stimulate special nerve cells in the nose, mouth, or throat. These cells transmit messages to the brain, where specific smells or tastes are identified. Olfactory (smell nerve) cells are stimulated by the odors around us, the fragrance from a rose, the smell of bread baking. These nerve cells are found in a tiny patch of tissue high up in the nose, and they connect directly to the brain. Gustatory (taste nerve) cells are clustered in the taste buds of the mouth and throat. They react to food or drink mixed with saliva. Many of the small bumps that can be seen on the tongue contain taste buds. These surface cells send taste information to nearby nerve fibers, which send messages to the brain.

If you’re wondering, “do braces cause bad breath,” we’re here to explain. Patients who wear fixed orthodontic appliances, such as braces, are at risk of developing bad breath due to the buildup of food particles on the teeth and poor dental hygiene. Therefore, it is crucial to maintain proper oral hygiene to prevent unpleasant mouth odors. Crooked teeth can cause bad breath as well—as it is more difficult to clean between the teeth. Alternatively, removable orthodontic appliances, such as aligners, may be a better option since they are easier to clean as they can be removed from the mouth.

Dentures, removable replacements for missing teeth, come in two types: partial and complete dentures. Dental implants and bridges are suitable alternatives to dentures. Though it usually takes a while to get used to eating and speaking with new dentures, denture adhesives can improve the stability of the denture and provide a sense of security for the denture wearer.
In some cases, bad breath may be a symptom of an underlying medical condition. Conditions such as gum disease, sinus infections, respiratory infections, and acid reflux can all cause bad breath.

Tooth decay, also known as cavities, can also cause bad breath. When bacteria in the mouth break down sugars and carbohydrates from food, they produce acids that can erode tooth enamel and lead to cavities. These cavities can harbor bacteria and food particles, resulting in bad breath.
Those who have bad breath and have just started a new medication or who have had recent dental surgery should consult their healthcare provider.
