Sedation Dentistry in Hamilton

Whether you are fearful or have anxiety about visiting the dentist, have pain or
require extensive dental work, Downtown Sleep Dentistry and Oral Surgery can give you the peace of mind you need to get the treatment you deserve.

Levels of dental sedation and anaesthesia

Downtown Sleep Dentistry and Oral Surgery offers multiple levels of in-office sedation and anaesthesia options for everything from routine cleanings to surgical procedures.

Nitrous Oxide

Nitrous oxide is a conscious sedative, which is administered by breathing in a mixture with oxygen through the nose. This is effective in allowing our patients with mild anxiety to stay calm during treatment.

With nitrous oxide, you will still be able to communicate with us. Nitrous is often appropriate for less invasive or shorter appointments. Once your appointment is finished, you will be given oxygen to help remove any lingering gas from your system.

The calming effects of the nitrous wear off almost as soon as it is turned off, with little to no side effects. One of the advantages of nitrous oxide is that you can attend your appointment unescorted, and can drive home or take public transportation as the effects wear off completely before you leave the office.

For those looking for a little bit more of a sedation effect than nitrous oxide, but don’t want to be fully asleep, our downtown Hamilton dental specialists offer oral sedation. This is usually administered by drink or pill, or can be combined with the calming effects of nitrous oxide.

Though still not fully asleep, oral sedation will put those with mild to moderate dental anxiety in a calm and peaceful state-of-mind. This will allow your dental work to be completed while you stay relaxed. You will require a responsible adult to drive you to and from your appointment, and to stay with you for the remainder of the day.

Deep Sedation and General Anaesthesia

Most of our Hamilton and area patients prefer to be asleep for their dental care, for which deep sedation is well suited. From the patient’s perspective, the entire procedure is over in the blink of an eye.

Deep sedation is commonly achieved through an intravenous (IV). Deep sedation is what adults experience to allow for colonoscopy procedures to be successful and comfortable. Deep sedation is extremely predictable and is safe for many of our patients. This same technique and medications can be used to treat adults and children alike for restorative dental procedures and for oral and maxillofacial surgery

For children, deep sedation is the most common and effective option. This allows our specialists the opportunity to provide the best possible outcome. This is a very predictable and safe source of sedation and is most commonly used for younger, high-anxiety, fearful or uncooperative patients or for those who require extensive or technique sensitive dental work. All of our specialists are highly trained and proficient in working with children, so that you can feel confident when your child is in our care. 

The Royal College of Dental Surgeons of Ontario only permits dentists who completed formal multi-year residency training and education in anaesthesia to practice this type of anesthesia. During your treatment, in addition to your always present anaesthesia provider, our nurses also monitor you ensuring safety. After completion of your treatment, dedicated recovery room nurses monitor all patients in our recovery unit. Our nursing staff are trained and current in Advanced Cardiac Life Support (ACLS) and Paediatric Advanced Life Support (PALS). We are fully equipped, trained and prepared for the remote possibility of an emergency.

Our facility and equipment are routinely inspected by our regulatory body and exceed the Canadian Academy of Dental Anaesthesia guideline requirements.

Sedation Dentistry FAQs

What types of treatments are possible while under sedation?

Several treatments can be done under sedation. These procedures are used to minimize the patient’s anxiety and make them feel at ease. These can be cleanings, cavity fillings, tooth extraction, root canal, dental implants, gum treatments, cosmetic and orthodontic care.

Are there any side effects or risks associated with dental sedation?

Yes There are a number of side effects and risks of sedation in dentistry that can range from drowsiness and dizziness to something more serious, such as allergy, respiratory depression or even death. Risk depends on the level and type of sedation that is used, as well as your previous medical history in regard to your sensitivity to anaesthetic, among other things. You should discuss with your dentist about your medical history and concerns prior to sedation in order to minimise the risk as much as possible.

What kind of patients benefit from sedation dentistry?

Sedation dentistry benefits patients who experience dental anxiety, have a strong gag reflex, struggle to sit still for procedures, or require extensive dental work. It also helps individuals with special needs receive necessary dental care in a comfortable and stress-free manner. By providing relaxation and reducing discomfort, sedation dentistry ensures a positive experience for patients who may otherwise find dental visits challenging.

Is there a diet to follow when undergoing sedation dentistry?

The answer to that question is dependant on the type of sedation. Anytime that you are going to undergo sedation dentistry, you might be advised by your dentist to avoid foods or beverages before the procedure. This is so that in the event you experience nausea and/or vomiting during the procedure, the chances of that vomit entering your lungs will also be reduced. You might also be told to avoid eating hard foods until the anaesthesia wears off completely to avoid biting your cheeks or tongue by accident.

How long does it take for sedation to wear off after the procedure?

The length of sedation effects relies on many variables such as type and dosage of sedative utilized, degree of health and metabolism of an individual. Under normal circumstances adjusting deeper sedation methods for instance nitrous oxide may be felt quickly following the procedure compared with the latter methods that may stay longer. Your dentist will be offered specific guidance on the post-operation care and what activities to be resumed when it’s safe.

Getting my wisdom teeth removed as an adult was daunting due to all the scary tales I'd heard. I found myself calling the office repeatedly for reassurance, and I must say, the staff at Downtown Sleep Dentistry and Oral Surgery truly transformed my experience. Their support and care made it incredibly calming. I can't recommend them enough. Dr. Cuddy was not just informative but also incredibly compassionate. Dr. Blackmore has been by my side throughout my entire recovery, checking in with me daily—it's been nothing short of amazing. The nurses were kind and really helped ease my nerves before the procedure. From the administrative start to the final step, it was simply the best. I'm planning to return to them for my TMJ issues in the future. Thank you to the ENTIRE team at Downtown Sleep Dentistry and Oral Surgery!
