Dental anesthesia implies the administration near the working area nerve of ​​a substance that has the role of temporarily inhibiting the sensitivity, so that dental treatment can be done without pain for the patient.

Types of dental anesthesia

  • Local anesthesia

    • Surface anesthesia: involves applying the anesthetic directly to the gum, with the role of numbing the area before administering the injectable anesthetic. The local anesthetic can be in the form of gel, spray, paste, liquid, powder.
    • Injection anesthesia: involves the insertion of the anesthetic into the tissues near the nerve endings through a puncture or through multiple punctures.Injection anesthesia comes to effect within 5 to 30 minutes. Its effect in time depends on the type of anesthetic used and the area where it has been injected. If the anesthetic also contains adrenaline, time required for its elimination from the body increases, consequently the anesthesia is felt for a longer time.
  • Sedation anesthesia: can be performed with inhalation or intravenous gas. In most cases when sedation is required, it is used in conjunction with local anesthesia.
  • General anesthesia: it is performed like anesthesia by sedation but it leads to a complete state of unconsciousness of the patient. It is very rarely used in dental interventions in case of patients with dental phobia in accentuated form or in exceptional cases, where other anesthetics do not work or cannot be administered.

Risks of dental anesthesia

  • The anesthetized area does not numb. There are different factors that can lead to this result, including the presence of an infection or even the presence of alcohol in the blood.
  • Very high pain during injection. This discomfort occurs when the needle penetrates directly the nerve endings.
  • Prolonged pain, numbness, temporary paresis of the facial nerve, allergic reactions, seizures, blood glucose fluctuation, hypertension.

Recommendations before dental anesthesia

  • In order to avoid possible side effects, the dentist should be informed about general preconditions, allergies and the medication taken.

  • Coffee or beverages containing caffeine 12 hours prior to the intervention should be avoided.
  • Rest and relaxation before the moment of intervention contributes to the smooth running of the procedure.
