If the hot-cold sensitivity is sudden and very severe in a few seconds, the living part of the tooth may have opened a little (due to decay or fracture). If the pain lasts for more than a minute after a hot cold, the living part of the tooth is infected. This indicates that root canal treatment may be required. Never put things like aspirin, alcohol, etc. into the dental tissue. It will not help, it will only cause the gums to burn.
    Severe night pain is one of the most common and complained conditions. Severe pain is usually caused by the inflammation of a severely decayed tooth. When the newly formed inflammation starts to damage the nerve of the tooth and tries to spread outward, it creates pressure on the tissues and therefore pain. Painkillers become insufficient after a short period of time. In such cases, you should consult a dentist. If necessary, the infection is suppressed with antibiotic treatment for a while. Afterwards, it may be necessary to perform root canal treatment by taking the nerve of the tooth by anesthesia.
    If the adult or primary tooth is broken or fallen out due to an accident, impact, etc., apply to your dentist by putting it in milk or serum (if it is not found, it may be in saliva) as soon as it can be used.
     Consult your dentist in case your pain gets worse as a result of getting hard materials such as toothpicks between your teeth.
