Emergency Treatment

If you ever find yourself in a dental emergency, please call Dr. Sims, the best dentist in Hamilton. We will fit you into our busy schedules!

Dental Exams & Cleaning

Teeth cleaning is a procedure for the removal of tartar or plaque that may develop even with careful brushing and flossing, especially in areas that are difficult to reach in routine toothbrushing. It is often done by a dental hygienist.

Professional cleaning includes tooth scaling and tooth polishing and debridement if too much tartar has accumulated. Typically after the cleaning is complete, the dentist will come and do a complete examination.


Local Anesthetic

Often called “freezing”, is an anesthetic medication placed near the treatment site to numb the area. It does not alter your mood, awareness, or memory of the procedure, but it eliminates pain.

Laughing Gas

Also called, Nitrous Oxide is a form of conscious sedation. It is used as a solution to decrease or eliminate anxiety and the worry about the pain involved in a dental procedure.

Crowns & Bridges

Crowns are used to protect, strengthen and rebuild broken or weakened teeth. Following preparation of your tooth a mould is sent to our master ceramist. Hand tinted porcelain is colour matched to your surrounding teeth. Our ceramist uses only the finest porcelain to produce natural looking teeth.

A bridge is used to replace single or multiple missing teeth. A crown is placed on the teeth on either side of the gap, forming a ‘bridge’. As with crowns, we either use porcelain on its own or combine it with zirconium or gold.

When having a crown or bridge done, many patients take the opportunity to whiten their surrounding teeth. The new teeth are matched to the whiter, brighter colour, producing a beautiful result.

Root Canal Therapy

Root canal therapy is a commonly used term for endodontic therapy.

After the tooth is ¨numbed¨, a small opening is made into the pulp chamber. The canals are located and measured, so they can be cleansed and shaped.

After space is cleansed canal system is filled with gutta-percha and a dental sealer material is placed in the root canal space. This allows the bone and tissue around the root to repair and heal.

Most often, a crown is placed in order to protect the tooth. The number of visits necessary to complete a root canal will vary depending upon the degree of infection, the number of canals in the complexity of the procedure.

Dental Implants

What is Dental Implant Treatment?

Think of dental implants as metal anchors, usually made of titanium, that are surgically placed into jawbone to hold permanent replacement teeth or dentures. Through a process called “osteointergration”, the jawbone actually attaches itself to the implant over time.

A single implant can be made when adjacent teeth are healthy and in place. During surgery, each implant is placed within the jawbone to serve as an anchor for the post that will eventually support the replacement teeth. It will take three to six months or more for the bone tissue to grow around the implants.

Once the jawbone is firmly healed around the implants. The post protrudes through the gum-line and serves as an anchor for the replacement teeth. After your gums have healed, the replacement teeth are securely attached to the post.

What are the benefits?

Since they are patterned after the structure of your natural teeth, they provide a highly stable support system for replacement teeth or dentures. Other benefits include:

Improved biting pressure. Implants can often restore the amount of pleasure that can be withstood to nearly the same level of healthy natural teeth.

Comfort and fit. Because your replacement teeth are anchored securely to the implants in your jawbone, they can’t slip and slide like unsecured dentures can.

Longevity and reliability. With proper oral hygiene and care, implants function like natural teeth. Most people who get them experience a renewed sense of self-confidence once they realize they can again chew, talk, laugh and smile with confidence.

How do I know if I’m a good candidate?

The permanently fixed denture is often an excellent alternative to removable dentures. If you face the loss of one or several teeth or if you’re dissatisfied with dentures or other options available to you, you may find that this treatment is right for you.

In general, we look for the following characteristics:
• General good health.
• Healthy gums.
• Sufficient underlying jawbone to support the implants.
• And a good attitude to ensure that you follow through with vital oral hygiene habits.

Wisdom Teeth

Sometimes wisdom teeth erupt and grown in with no problems. For many of us however, the development of wisdom teeth comes with a whole series of complications.

The most common complication is misalignment of the wisdom teeth. Poor alignment can cause crowding or even damage adjacent teeth, the jawbone or nerves. This is why sometimes it is necessary to remove wisdom teeth.

Bone & Gum Grafting

A lack of adequate bone or soft tissue can affect a smile’s aesthetics and create challenges in treating or health issues such as tooth loss and gum disease.
As such, bone or tissue grafting may be recommended in certain circumstances. This procedure involves taking bone or soft tissue from a donor site and attaching to the site of insufficient material.

Another problem addressed by grafting is receding gum tissue. This can occur as a result of periodontal disease.

In gum grafting, the dentist uses surgical techniques to insert donor tissue at the graft site. Gum grafts can also benefit patients with unusually thin gum tissue.

Depending on your case, you may benefit from bone or tissue grafting as one component of the overall effort to restore a beautiful smile.

Gum Reshaping

A beautiful smile is just a phone call away. If you’re unhappy with your smile, a simple ‘gum lift’ may be the answer. Your smile may be enhanced by simply re-contouring the shape and height of your gums to show more tooth.

Snoring Devices

There are significant health risks that are associated with snoring, such as an increased likelihood of high blood pressure for the snorer and poor sleep for both the snorer and anyone else within hearing range.

Our dentist in Hamilton can help alleviate this problem with a snore guard that slightly repositions your jaw and opens up obstructed airways.

A Snore Guard is a custom crafted mouth piece that is precisely fitted to the contours of your mouth. It creates the proper lower mandibular protrusion to clear blocked throat passages and virtually eliminate snoring.

Dental patients suffering from mild sleep apnea can obtain significant relief from disruptive snoring with this highly successful anti snoring device.

Sports Guards

Mouthguards are durable appliances that fit over your teeth for protection. When worn during contact activities, mouthguards help protect against injuries to the teeth, jaw and areas in and around your mouth.

Studies show that properly fitted sports guards can prevent or lessen the severity of injuries such as concussion, neck injuries, and other potentially severe injuries.

Night Guards

A night guard is plastic mouth piece worn at night to prevent damage to the teeth and jaw from Bruxism. Bruxism is the clenching or grinding of teeth, most commonly while sleeping.

Symptoms of Bruxism include:
• hypersensitive teeth
• aching jaw muscles
• headaches
• tooth wear
• damage and/or breakage of teeth and/or dental restorations
• a grinding noise during sleep, sometimes detected by a parent or partner

Invisalign is the modern approach to straightening teeth, using a custom-made series of aligners created specifically for you. These aligner trays are made of smooth, comfortable and virtually invisible plastic that you wear that gradually and gently shift your teeth into place, based on the exact movements the Hamilton dentist plans out for you.

There are no metal brackets to contend with, rather you put in new set of aligners approximately every two weeks until your treatment is complete.

The Orthodontics Treatment allows correcting dentofacial disharmonies.
Its main objective is an esthetic, in which we try to get a beautiful smile, and an ideal occlusion, as we look to improve the masticatory function and achieve stability between aesthetic and function.

This treatment generally gets done with brackets and it takes approximately 2 years, in which the patient has to attend monthly appointments.

Veneers are used to reshape, rebuild and strengthen crooked, chipped or broken front teeth.

If your teeth only have small chips or do not need significant shape change, the most appropriate veneer to use is one made of composite material and is sculpted over the surface of the tooth to create the new shape.

Where significant shape change is necessary, porcelain veneers are the preferred choice.

White composite fillings look far more aesthetically pleasing and blend in with the natural teeth around them. One minor problem with white fillings is that they could have a tendency to wear at a higher rate than the surrounding teeth. However, they are extremely easy to add onto if this happens.

Composite white fillings are a popular alternative and we have noticed that the local people prefer white fillings because they blend in much better with the surrounding teeth.

When it comes to first impressions, your smile can be a tremendous asset or your greatest liability. Visiting the dentist or using home teeth whitening systems can quickly and easily enhance your smile.
