Depends on tooth: This depends on the kind on injection used to give the novacaine. For and upper tooth it is placed near the tooth on the cheek side. For. Lower tooth it can be placed either next to the tooth or in the back of your mouth.

Local/Topical Anes: It is usually applied with a cotton-tipped like device to the area where the dentist intends to inject the local anesthetic that will ultimately have a more profound and longer effect than the topical.

See below: Topical anesthisa is placed in the area where needle would penetrate the mucosa. For upper teeth it's immediately next to the tooth being worked at but for lower teeth it is on the far back side or midways in your arch.

Topical: Directly where the injection will go.

Depends: The topical is placed where the needle will enter into tissue. Depending on where the nerve is that the dentist is trying to anaesthetize will depend on where he or she puts the topical. For mandibular (lower jaw) blocks, the dentist tries to anesthetize the nerve near the ramus of the mandible (lower back edge). Most other areas, the dentist can put the topical near the tissue by the tooth.

At the site: The topical an anesthesia is placed at the site where the puncture of the injection is to be administered

Topical: This is used to pre-numb the tissue prior to the needle inserting to deliver the anesthetic. It really needs to sit on the tissue for 3-4 minutes to be effective. The real secret to a painless injection is simply "Going Slow"!

Topical anesthetic: Most dentists place a cotton swab dipped in a local anesthetic gel directly on the area they will insert the needle. By numbing the area up first the injection if far less painful.

Vestibule: usually placed in the vestibule at height of contour or if on the lower between the coronoid notch and the pterygomandibular raphe. Basically, on the mucosa where the dentist intends to enter the tissue later.

Depends on location : depends on the location of the tooth/teeth that need anesthesia. As a general rule, on the upper teeth the gel and injection is usually olaced adjacent to the tooth that needs treatment. This is referred to as "infiltration". On the Lowe teeth, the gel and injection are placed at the far corner of the mouth. This is usually referred to as a "block."

Topical helps numb: Topical anesthetic is placed to locally numb the area so the application of the local anesthetic can be performed virtually painlessly.

Over injection site: Topical anestetic is placed directly over the site where the intended injection is to take place.

Site of injection: Depending upon what area is being treated, topical anesthetic is placed at the injection site(s). We now have an even better way to administer anesthetic, in addition to topical with the Dental Vibe. Most times injections can be pain free! http://www.dentalvibe.com/ to learn more and find a dentist near you. Our patients LOVE it!

Injection site: After drying the tissue to promote better transepithelial penetration, a small amount of the topical is swabbed across the injection site. Best to keep this area dry to allow it to work most effectively. Then while tensing the tissue the injection can be initiated with very little , if any, sensitivity.
Dr. Paul Grin

Soft tissue: The topical anesthetic is placed for at least two to three minutes on the soft tissue to increase comfort before the injection.

Injection site: Topical anesthetic is usually a gel placed at the site where the dentist is going to give you the injection.
Dr. Bruce Apfelbaum
Dentistry 52 years experience
At: Right at the site of the injection.
Dr. Patrick Ralph

Topical: The topical is placed on the site of the injection. Usually, the area is dried the topical is then place to "numb" the area of needle placement. While this will prevent pain upon injection this will not prevent pain of the anesthetic being injected. In order to prevent pain upon injection of the anesthetic this requires a slow rate of delivery of the anesthetic.
