The same purpose, a different way to deliver it
Local anaesthetic temporarily reduces sensation in the area being treated. Dentapen, made by Septodont, is a cordless, pen-shaped applicator that controls the delivery flow electronically. It uses an anaesthetic cartridge and a needle, just as a conventional dental injection does.
This is not general anaesthesia or a needle-free injection. You remain awake. The dentist may still use a conventional syringe when that is more appropriate.
Local anaesthetic is provided at no additional charge at ProDent. This also applies to Dentapen when it is suitable for your treatment.

Dentapen compared with a conventional syringe
| Feature | Conventional syringe | Dentapen |
|---|---|---|
| Appearance | A dental syringe | A pen-shaped applicator |
| Delivery | The clinician controls the flow manually | Electronics help control the flow |
| Needle | Required | Required |
| Purpose | Local pain control | Local pain control |
Controlled delivery may help make the injection more comfortable for some patients, especially where pressure during injection is a concern. It does not remove all sensation or guarantee a completely painless injection. The drug, dose and injection technique still matter.
When might it be used?
Dentapen can be considered for suitable procedures such as fillings, root canal treatment and oral surgery. It may also be an option for children and people who are anxious about injections.
The dentist decides whether it is appropriate for the required injection and your circumstances. Tell us about dental anxiety in advance so we can discuss the appointment and explain each step.
What to tell your dentist
The applicator does not change the precautions that apply to the anaesthetic medicine. Bring a list of your medicines and tell the dentist about your medical history, pregnancy and any previous reaction to an injection.
| Information | Why it matters |
|---|---|
| A confirmed allergy | The anaesthetic or another ingredient may need to be avoided |
| A previous injection reaction | The symptoms and circumstances help distinguish allergy from other causes, such as fainting or anxiety |
| Heart or circulation conditions, blood pressure or thyroid problems | The drug and its ingredients need to be assessed in context |
| Pregnancy or breastfeeding | The clinician selects appropriate treatment and anaesthetic |
| Liver disease, low body weight or a child’s age and weight | These can affect the choice and amount of medicine |
| Blood disorders, including methaemoglobinaemia | Some medicines require particular precautions |
| Acute illness or difficulty cooperating | The timing or approach to treatment may need adjustment |
Do not stop prescribed medicines on your own. A previous episode of feeling faint does not automatically mean an allergy, but it should still be discussed. Describe exactly what happened and bring any relevant medical information.
During and after the injection
We review your history, prepare the injection and administer the anaesthetic. The dentist allows time for it to take effect and checks the area before starting. Tell them if you can still feel pain during treatment so they can reassess it.
Numbness can last beyond the appointment. Take care not to bite your lip, cheek or tongue, and avoid hot food or drinks while sensation is reduced. Follow your dentist’s instructions, especially when supervising a child after treatment.
Common questions
Is Dentapen completely painless?
No method can promise that. Electronic delivery controls the flow, but you may still feel the needle or pressure. Tell the clinician about discomfort or anxiety.
Does it avoid the needle?
No. Dentapen still delivers anaesthetic through a needle. Its pen-shaped appearance and controlled flow are the main differences from a syringe.
Do I pay extra for it?
No. Local anaesthetic, including Dentapen when suitable, is not charged separately at ProDent.
Can it be used for children?
It may be suitable. The dentist considers the treatment, the child’s cooperation and the appropriate medicine and dose.
Why might the dentist use a syringe instead?
Different injections and clinical situations call for different techniques. The clinician chooses the method appropriate to your care.
Does electronic delivery remove medical contraindications?
No. It controls delivery, not the medicine’s effects on the body. Allergies, interactions and other precautions still need to be assessed.
Can I receive local anaesthetic during pregnancy?
Dental treatment with an appropriate local anaesthetic can be possible during pregnancy. Tell your dentist that you are pregnant so the timing, treatment and medicine can be assessed for you.
