The strength lidocaine that dentists use is 2% or 5% gel, 2% solution, 4% or 5% solution, 5% ointment, or 10% spray.
The onset action of lidocaine is 1 to 2 minutes and the action is around 15 minutes.
Dentists use local anesthesia to numb the areas around your mouth.
Lidocaine is the most common anesthetic that dentists use now.
The safest local anesthetic in dentistry is Articaine, prilocaine, Lidocaine and mepivacaine.
Articaine is the safest local anesthetic for people with kidney disease and liver disease.
The most popular dental topical anesthetic is Benzocaine and is available in many concentrations although the 20 percent preparations like Gingicaine are the most often used ones.
Benzocaine has a rapid onset of action.
The most painful dental anesthetic is inferior alveolar injection.
The most difficult tooth to anesthetize is the mandibular molars.
A full mouth extraction of teeth takes around 2 hours and you will be completely numbed before and during the teeth extractions.
You can also ask for sedation at the dentist when having your tooth extracted so you will be completely put under and unaware of what is going on.
Dentists no longer pull teeth unless absolutely necessary.
Dentists will still pull teeth but they will want to try and save the tooth first and use tooth extraction as a last resort.
A common reason for dentists not wanting to pull a tooth is because when the dentist does pull a tooth it can lead to the other teeth shifting.
Extracting and pulling teeth also can result in long-term detrimental effects on many patient's faces and the health of their gums and bones.
When your tooth can't be repaired, tooth removal may be the best option for you.
However your dentist will talk through your options with you during your consultation.
If you think you might need a tooth extracted then the dentist will most often pull the tooth.
The third molar, also termed the wisdom tooth, is the most difficult tooth to extract.
Because of their location and anatomy, lower molars are typically the most difficult to extract.
Lower molars have multiple roots, making removal from the jawbone more difficult.
For certain patients, it may be possible to widen the dental palate in order to make room for the teeth, rather than extracting them.
This is more commonly effective in children, whose bones are still growing and can thus adapt quickly to the expansion of the palate.
