What is dental anesthesia afterall?


Local anesthesia represents a major progress in the treatment of heavy pain caused during dental treatments, mainly in the case of oral surgical procedures. The method consists of temporarily blocking electrical signals along the nerves in order to induce loss of sensation on the operational sight.

Types of local anesthesia used for dental treatments

Without going into further technical details about the various types of dental anesthesia, there are three main groups used during the placement of dental implants for example:

  • contact anesthesia which allows the gum to be put to sleep by only affecting the surface,
  • local anesthesia can make a group of 2 to 3 teeth insensitive,
  • loco-regional anesthesia affects the whole jawbone at the same time.

The dental practitioner will use either of these techniques as required, depending on the type of treatment applied, such as the placement of dental implants or other surgical and even prosthetic dental treatments.

Controlling pain is a daily concern for dentists

Although local anesthesia only affects pain from a physical perspective, it is possible to put the whole operational site to sleep in the majority of the cases. Therefore, practicing local anesthesia requires thorough knowledge in various fields: anatomy, physiology, pharmacology – but mastering the technique in a timely manner is a decisive factor for success too.

The majority of treatments performed at a dentistry requires prior local anesthesia, which is most often done by injecting the anesthetic product from a glass bulb with the help of a needle. The necessary dose of anesthetic product is effective within one minute and usually does not have any toxic effect.

However, it is possible to have allergic reactions to anesthetics during your dental treatment and most often these are unpredictable, so it is highly recommended to always report a known allergy to any kind of medication to your dentist and give its name accurately, as it is also true for anesthetics.

Adrenaline, a hormone that is usually associated with anesthetics and often used during dental treatments to improve efficiency and limit bleeding, may decrease blood sugar level and increase heart rate and blood pressure. For these reasons, this type of local anesthesia is not recommended by dentists for patients with diabetes, hypertension or coronary insufficiency.

After leaving the dental clinic

After receiving local anesthesia for example during the placement of dental implants, certain preventive measures need to be taken to avoid biting your lips, cheeks, tongue or swallowing something – as long as the insensitivity persists. This precaution also applies to children. The damage caused by a deep bite is easily comparable to that of a large burn and takes a long time to heal after the oral surgery.

Contrary to the common knowledge, pregnancy or breast-feeding are not strict contraindications to local anesthetics when undergoing a dental treatment. During pregnancy, local anesthesia can be practiced safely if you decide to have for example dental implants placed in your jawbone. Fighting the pain is much more harmful to the fetus than the anesthetic product itself, used during an oral surgey.

Is the price of local anesthesia included in the dental treatment?

Local anesthesia is usually not indicated separately on the price list, since it is generally included in the fee of the dental treatment itself. In other words, the whole price of a certain dental treatment will remain the same, regardless of the number of consecutive doses of local anesthesia used during the surgical operation or prosthetic dental treatment.
