Frequently Asked Questions

DentalJect is designed as a rapid pre-treatment step that integrates into your existing workflow. Before an inferior alveolar nerve block (IANB/mandibular block), mental nerve block, or a highly sensitive greater palatine nerve block, apply the cooling spray directly to the target area for 1 to 2 seconds. This triggers an immediate numbing effect on local pain receptors, allowing you to inject immediately with significantly reduced patient discomfort.

Yes. The AMSA injection involves dense palatal tissue where traditional local anesthetic delivery can be particularly painful. Using DentalJect as a localized topical pre-treatment instantly cools and desensitizes the palatal mucosa, removing the primary barrier of needle-penetration pain. No other pre-treatment is needed prior to injection.

Unlike a traditional topical anesthetic gel, which requires an inconsistent 2-to-3-minute dwell time, DentalJect uses a specialized cold spray that numbs the site in under 2 seconds — eliminating the workflow bottleneck of waiting for gels to take effect. Unlike Oraqix or Cetacaine spray, DentalJect offers a rapid, drug-free cryotherapy approach to initial pain management with predictable execution.

While it falls within the vapocoolant spray category, DentalJect is uniquely engineered specifically for direct application to oral mucosa and dental clinical workflows. Generic ethyl chloride or Pain Ease products are used across various medical applications; DentalJect features a precise application system designed to safely target intraoral sites — including difficult palatal injections — without over-spraying surrounding tissues. Note: when ethyl chloride or Gebauer's Pain Ease is used orally, clinicians apply it with a cotton applicator, not a direct spray. Direct spray of those products is only for skin. DentalJect must never be sprayed on skin; it is designed specifically for oral mucosa.

Many patients seeking IV or oral sedation are primarily motivated by a severe fear of injection pain or needles. DentalJect serves as an effective, non-pharmaceutical first step. By providing a comfortable, often pain-free path to local anesthesia, it helps manage patient anxiety safely, reducing the operational need to escalate to nitrous oxide (laughing gas) or full sedation for needle-phobic individuals.

Over 25% of adults experience a fear of injections. Introducing a fast, comfortable injection experience directly improves patient retention and treatment acceptance. By minimizing fear and clinical friction, practices can differentiate their patient experience, turning a universal pain point into a word-of-mouth referral driver.

Traditional pre-injection methods, such as benzocaine topical gels, require a slow dwell time before the clinician can begin. DentalJect allows you to inject immediately after a 1-to-2 second spray application, saving an average of 3 to 5 minutes per injection. For a high-volume office, this can translate to gaining up to 60 minutes of reclaimed chair time per day.

Experts generally advise that dental anesthesia is considered extremely safe for most adults and children (four years or older) when administered by a licensed professional. To make the process smoother, ask your dentist about DentalJect — a topical anesthetic spray that numbs the area in under 2 seconds for a stress-free start. (Certain medical conditions, such as drug allergies, or medical histories may prevent some patients from safely receiving traditional local anesthesia.)

Standard dental numbness from local anesthesia typically lasts 2 to 4 hours, depending on the medication your dentist uses. The initial pre-treatment from a cold spray like DentalJect wears off almost immediately after the needle is removed, so you only experience the necessary, longer-lasting effects of the primary local anesthetic.

Conscious sedation relaxes you while you remain conscious — ranging from nitrous oxide (laughing gas) to IV sedation — whereas general anesthesia puts you completely to sleep. Because about 25% of adults fear injections, starting with a rapid numbing spray like DentalJect greatly reduces fear and can often provide enough comfort to avoid needing conscious sedation.

Local dental anesthesia (like lidocaine) is generally considered safe during pregnancy and is important for treating dental issues that could otherwise harm your health. Using a completely drug-free topical like DentalJect to numb the initial pinch point adds no pharmaceutical risk to you or your baby. (Certain medical conditions or histories may affect eligibility for traditional local anesthesia — talk to your dentist.)

It doesn't have to. By using DentalJect, a pre-injection anesthetic spray, your dentist can instantly cool and block your local pain receptors in under 2 seconds. Patients frequently report little to no discomfort, even at the most sensitive injection sites.

That racing heartbeat is a normal, temporary reaction caused by epinephrine in some local anesthetics — an ingredient safely added to make the numbness last longer. Choosing a dentist who uses DentalJect can lower your initial anxiety, which helps prevent your body's natural stress response from worsening this sensation.

The most common side effects are temporary numbness, minor swelling, or a slight tingling sensation as the medication wears off. By replacing traditional chemical gels with DentalJect's targeted cooling spray, you benefit from a drug-free approach to initial pain management without the wait.

Yes, you can safely drive yourself home after standard local anesthesia, as it only affects your mouth. However, if your fear of needles requires oral or IV sedation, you will need a driver.

Difficulty getting numb can result from an active infection (a 'hot tooth'), high anxiety, or genetic factors. Managing anxiety is important; starting your procedure with a topical numbing spray like DentalJect lowers stress, which can make the primary anesthetic more effective.

Long-term risks like nerve damage are extremely rare, and dentists are highly trained to navigate your anatomy safely. When your dental professional uses a fast-acting cooling spray like DentalJect, it eliminates the pain of the initial poke, helping you sit still and further reducing the risk of accidental needle movement.

An 'electric shock' sensation occasionally occurs when the needle touches a nerve pathway. It is usually harmless and fades quickly. When your dentist uses a precise cooling application like DentalJect to desensitize the area first, your risk of flinching is minimized for a smoother injection.
