Dubai, United Arab Emirates – Despite brushing teeth before going to bed, many people suffer from bad breath and an unpleasant taste after waking up.
The British newspaper “Metro” quoted dentist Sofina Ahmed as saying that there are several intertwined factors behind this phenomenon.
She said that bad breath upon waking up in the morning goes beyond the idea of food scraps to reach the sleep mechanisms themselves.
The doctor confirmed that there are 3 main reasons behind this phenomenon:
Decreased saliva production at night
Saliva secretion slows down naturally during sleep, and the problem becomes more apparent, especially when opening the mouth or breathing through it.
This reduces the flow of saliva, which acts as a natural mouth cleaner, and creates an ideal environment for the proliferation of bacteria that cause unwanted odor and taste, especially on the tongue.
sinus problems
The salty or bloody taste upon waking is directly related to the health of the nose and sinuses.
Sofina points out that this taste may be a sign of an infection, allergy, or condition such as rhinitis.
Which leads to what is known as postnasal drip
Mucus seeps from the nose into the throat during sleep, carrying with it bacteria, inflammatory products, and even tiny traces of blood from irritated tissues, causing this taste.
Silent acid reflux
If the dominant taste in your mouth when you wake up is acidic or metallic, the cause may be due to increased acidity in the mouth at night as a result of food residues being broken down by bacteria.
Laryngopharyngeal reflux, or “silent reflux,” also plays a pivotal role.
Stomach acids seep into the throat and mouth without causing the usual burning symptoms, leaving this sour taste until the morning.
An unexpected factor that affects the sense of taste is the quality of sleep itself.
According to Sofina, poor sleep hygiene can distort our perception of flavors.
If sleep is uncomfortable or accompanied by snoring or panting, or if the person suffers from sleep apnea, this may lead to a partial loss of sensitivity, causing a sweet, salty, sour and bitter taste.
Sofina recommends several steps to avoid oral problems and waking up feeling uncomfortable, which are:
- Drink a glass of water before bed and keep another glass next to the bed to keep the mouth moist and reduce bacterial growth.
- Stimulate saliva production in the evening by chewing sugar-free gum.
- Incorporate tongue scraping into your sleep routine to remove bacteria and stuck-on residue.
- Stick to using dental floss and an antibacterial or pH-neutral mouthwash for a thorough mouth cleaning.
