Help for the Nervous Patient

Conscious Sedation

For many people, visiting the dentist can be a frightening experience.

At DJ Maguire Dental Group our teams are fully trained in helping nervous patients relax naturally before any treatment.

However, because your comfort is our top priority, we also offer Conscious Sedation to help ensure your fears are reduced as much as possible.

The Conscious Sedation is given gently by an injection in either your arm or the back of your hand. The sedation takes effect very quickly and though you will feel drowsy during your treatment you will still be able to respond to any questions your dentist might have and cooperate with them fully.

The sedation can also cause temporary amnesia so it’s likely you will have little or no memory of going through the treatment. You will also likely be drowsy or sleepy throughout the rest of the day so it’s important that you do NOT drive, drink alcohol or operate machinery for a period of time prescribed by your dentist.

A little bit about David

David graduated from Queen’s University Belfast in 2014. Following this he completed his foundation training in Bristol before returning to Northern Ireland where he has been working within DJ Maguire Dental Group since 2015. He passed the exams for membership of the joint dental faculties in 2016 and undertook the diploma in conscious sedation through Trinity College Dublin from 2019 – 2021, graduating with distinction. He is currently completing a Master’s degree in advanced restorative dentistry through the University of Aberdeen.

David provides conscious sedation (both inhaled gas and air, and intravenous sedation) for anxious and phobic patients. He mainly provides this service on a Thursday from North Street Dental Care in Lurgan. He provides all forms of dental treatment under sedation including cosmetic and restorative dentistry. His favourite approach to treatment is to use the most up to date methods of restoring teeth, using the most advanced materials and techniques to avoid root canal treatment and preserve as much of the natural teeth as possible. This is known as the biomimetic approach to dentistry and it is considered the pinnacle of modern restorative dentistry.

Will I still feel pain if I am sedated?

Mostly likely, no. Many patients feel no discomfort at all during the treatment and some feel surprisingly good afterwards. However, you will be groggy and probably a bit confused, so you will need a friend or family member to make sure you get home safely.

Is it safe?

The Conscious Sedation we use is time proven, effective and safe. For added safety, before we start any treatment, we will review your medical history to be sure there are no issues and, if you are a good candidate, you will be monitored very closely during the treatment.

What treatments is sedation used in?

If you are uneasy or anxious about your treatment you can rest easy knowing that sedation can be used in nearly any and all types of cosmetic and general dentistry. Before they begin any treatment your dentist will happily discuss your sedation options with you.
