What causes a slightly numb and cool sensation in the mouth, and what should I do about it?

A slightly numb and cool sensation in the mouth may be caused by physiological factors, or it could result from pathological conditions such as allergies or cheilitis. Symptoms can be improved through general treatments or medication. The specific analysis is as follows:

1. Physiological Causes

If one remains in a cold environment for a prolonged period, the mouth may be exposed to cold stimulation, affecting local blood circulation and causing the aforementioned sensations. These symptoms usually gradually subside after improving the ambient temperature and taking proper warming measures.

2. Pathological Causes

1) Allergy

In daily life, accidentally consuming foods that trigger allergies may induce an abnormal immune response, leading to tissue and cell damage and resulting in the symptoms described above. In such cases, it is recommended to take antiallergic medications under medical guidance, such as diphenhydramine hydrochloride tablets or chlorpheniramine maleate tablets.

2) Cheilitis

Cheilitis is an inflammatory condition affecting the lips. If this condition is present, the inflammation may lead to the aforementioned discomfort. Treatment may include medications prescribed by a doctor, such as loratadine tablets or cetirizine hydrochloride tablets.

Besides the causes mentioned above, such symptoms could also be due to other conditions including facial neuritis, facial nerve paralysis, or brain tumors. It is advisable for patients to promptly visit a reputable medical facility, undergo necessary examinations, and actively cooperate with doctors for appropriate treatment.
