Now No Fear of Anesthetic Needles in Dental Procedures!

Updated on October 30, 2014

Many of us don’t go to a dentist however severe there problem is, just because of the fear of the atmosphere of clinic. The atmosphere includes smell of medicines, noise of dental drill and anesthetic injections. However, new needle-free anesthetic techniques can give such patients relief from the fear of injections at least. There are many such techniques available now and you should check with the dentist if he or she uses them. Apart from the removal of dental anxiety, they have other remarkable benefits too.

Transcutaneous Electrical Nerve Stimulator (TENS)

This is a type of electronic anesthesia in which no anesthetic drug is used. It is a device through which the patient can control pain-relief by using a hand-held unit which is attached to the stimulation pads kept nearby. The voltage used for electrical current in TENS is ultra-low. The current thus produced can modulate the ability of nerves to send signals of pain to the brain.

Benefits – There are no side effects and after effects, since no anesthesia is used. After the procedure, electrodes of the device are removed and then you are free to go home without a numb chin or impaired speech. Some patients have severe sensitivity towards some kinds of anesthesia. This probability is also eliminated with the use of TENS, because no anesthesia is used.

Uses – TENS is widely used as an anesthetic tool in procedures like dental cleaning and tooth filling.

Subgingival Anesthesia

This is used by directly applying it to the gum pockets using a special applicator. It takes around 30 seconds to get the area anesthetized. Its effect remains for 15 to 30 minutes and the procedure may take more time, so another application can be made.

Benefits – The main benefit of this anesthesia is it is confined to the area of the procedure; so exactly that portion is made numb which needs anesthesia and so you don’t have a feeling of fat lip or numb chin after the procedure, as happens with conventional anesthesia.

Uses – Scaling and root planning and the ‘deep cleaning’ procedures which need anesthesia for patient’s comfort can be carried out with successful use of subgingival anesthesia.

Cryogenic Anesthesia

These are one-time usable rings that are kept in freezer for minimum 30 minutes and at the time of procedure taken out and applied on the teeth. There is a liquid inside these rings which is freeze-resistant so that it can be molded into the shape of the teeth and gums. These can be reapplied so as to ensure numbness during the entire procedure.

Benefits – Cryogenic anesthesia rings can quickly anesthetize gums and teeth enough for most of the dental procedures.

Uses – Cryogenic anesthesia is useful for dental fillings, crowns, root canal, tooth extraction, scraping, dental cleaning and adjustment of braces. Specific tools are in a development process for wisdom teeth and molars too.

These techniques are quite new and may not be available with all the dentists. If you are particularly keen about getting their advantages, you should enquire first if the dentist uses them or not.
