Restorative Procedures

Sedation - Oral Sedation & Nitrous Oxide

Some people are anxious when they see the dentist and are not able to relax enough to receive treatment. Queenston Dental offers oral sedation and nitrous oxide sedation. Both are very safe and effective ways of having treatment done for nervous or anxious patients.

Oral sedation involves taking an oral sedative prior to coming to your appointment. Your vital signs and comfort level will be monitored throughout your visit.  You will need to be driven to your appointment and will need a ride home.

Nitrous Oxide Sedation or “laughing gas” is used for its pain blocking or reducing effects. It is inhaled through a small nasal mask and helps the patient feel relaxed and comfortable throughout their treatment. The amount of gas received is monitored and controlled by the dentist throughout the visit. Once the mask is removed, you will likely be able to drive yourself home  and carry on with your day as normal.


White/Composite Fillings

White/composite fillings are tooth-coloured fillings. Aesthetics are a big positive of composite fillings as the dentist can blend the shades to create a colour that is identical to the actual tooth. Composites also bond to the tooth and support the remaining structure. It prevents breakage and insulates the tooth from temperature changes. We use stain resistant and extremely durable composites.

Amalgam Fillings

Amalgam fillings (silver fillings) are occasionally recommended for molars or back teeth where white fillings may be difficult to place. We choose the material depending on our patient and the position and location of the tooth that needs treatment.

Root Canal

Inside our teeth, under the hard enamel and dentin layers, there is a soft tissue layer called the pulp. It contains nerves, blood vessels and connective tissue. If it gets injured or infected, the nerves die and the tooth may become infected and painful. Root canals are meant to save the damaged teeth. The dentist removes the infected nerve tissue and then places a soft filling material inside the root, allowing any infection to heal. Following this, the tooth is sealed permanently with a filling and typically a crown is placed over the tooth to protect it and restore it back to function.

Crown / CEREC (Single Visit Crowns)

A crown is a cap in the shape of a tooth that is placed over a damaged or decayed tooth in order to restore its size, strength, shape and improve its function. They may be used to protect weak teeth from breaking or to restore worn teeth, support teeth with large fillings, to keep dental bridges in place, cover discoloured teeth and dental implants or to make a cosmetic modification. A patient who has undergone a root canal will need a crown to provide support and strength to the tooth after the treatment. We use the highest quality material for our crowns and the benefits are long-lasting.

CEREC (CEramicREConstruction) Crowns = same day crowns. A traditional crown requires two appointments. The first appointment is for preparing the tooth, taking an impression and fitting a temporary crown on the tooth. The second appointment replaces the temporary crown with the permanent one. The time between appointments is generally about 2 weeks(the time it takes for the dental lab to make the crown). With a CEREC crown, the whole procedure can be done in just one appointment. CEREC utilizes 3D imaging and CAD/CAM technology to design the crown without taking a traditional impression. The 3D design is transmitted wirelessly to a milling machine that carves the tooth in our office. You will receive your new porcelain crown the same day! Ask the dentist if a CEREC crown could work for you!


Dental implants are artificial roots that are placed in your jaw to support a bridge, denture or a replacement tooth. They are a great option for people who have lost their teeth due to an injury, periodontal disease, infection or decay. With implants, patients don't experience the moving, slipping, and irritation that accompany dentures. Implants are made of medical grade titanium that is compatible with your jaw bone. They can support crowns or bridges that feel, look and function just like natural teeth. Implants can also be used to stabilize and prevent dentures from moving and falling out. The dentist will create a treatment plan specifically for you. Once the treatment is complete, the dentist will work closely with you to help you to maintain your implants and keep them healthy.


A bridge, as the name suggests, is used to bridge the gap that is created by missing teeth. They are made of alloys, porcelain, gold, or a combination of these materials. Bridges restore your natural smile and also the ability to speak and chew properly. Apart from maintaining the shape of the face, they also stop the remaining teeth from drifting away from their position. Most importantly, they redistribute your bite forces by replacing the missing teeth. Our dentists are experienced in creating dental bridges that will restore your smile.

Inlays and Onlays

If you don't need a full crown, but are in need of a long-lasting strong restoration, inlays or onlays might be the perfect solution. Essentially, it is a restoration procedure in which porcelain material is used to replace missing or weak tooth structure. We have received nothing but positive comments on the appearance and function from patients who have undergone this procedure.
