Sensitivity to dental anesthesia

Fear of needles and fear of dental anesthetic injection is one of the most common fears and concerns of people. To the extent that this concern becomes a factor preventing a person from going to the dentist and neglecting the health of his or her teeth. Meanwhile, in addition to fear, some people may be allergic to dental anesthesia.

In such a way that after the injection of the anesthetic ampoule and heartbeat, it will come to the person in a moment and change his mood. In the following, we will talk more about sensitivity to dental anesthesia and the treatment of sensitivity to dental anesthesia.

Allergy to dental anesthetic

The substance used for dental anesthesia contains adrenaline (epinephrine). In some people, this substance causes increased heart rate, weakness, and sometimes lethargy. Epinephrine in the dental anesthetic causes vasoconstriction due to its pharmacological action, which increases the duration of anesthesia.

During this process, people think that they are allergic to the dental anesthesia injection and consider all these reactions as complications of the dental anesthesia injection.

Heart palpitations or changes in breathing or lethargy are reactions that people consider to be among the symptoms of sensitivity to anesthetic drugs, and they immediately seek treatment for sensitivity to dental anesthesia or give up treatment.

Meanwhile, people with the following conditions should not use dental anesthesia and must discuss their conditions with the doctor before treatment.

  • People with heart disease
  • People who have had a history of stroke
  • People with high blood pressure
  • People who have similar sensitivity to the anesthetic.

Treatment of sensitivity to dental anesthesia

As we said, the symptoms that occur after the injection of dental anesthesia are caused by the epinephrine contained in the dental anesthetic. These symptoms are not an allergic reaction and are transient complications and disorders and are mostly related to the patient’s psychological behaviors and stress.

These symptoms are not alarming and it is enough to share this issue with your dentist in Kingston to prevent the occurrence of similar symptoms or to replace lidocaine in dentistry with other drugs to prevent the occurrence of sensitivity to the anesthetic.

How long does tooth numbness last?

When the doctor injects you with a dental anesthetic, it usually takes 10 minutes for the anesthetic to take effect. How long it takes for the tooth anesthesia to wear off depends on the number of anesthesia injections or the injection site of the dental anesthesia ampoule. For example, the numbing effect of upper or lower jaw teeth disappears within 1 hour. Of course, it takes up to 2 hours or more for the dental anesthesia to wear off in areas with soft tissue (cheeks, lips, lips, tongue, etc.)
