Dental Restoration

Dental restoration is a very common procedure and is used to fill the cavities in the teeth. There are generally 2 types of material used in a dental restoration:

• Composite resin, or white filling material that is the same color as that of teeth
• Amalgam, or alloy mixed with mercury

Composite Resin Restoration
Composite resin restoration, also known as white filling, is a great product in modern dentistry. It has been developed for quite some time and reached a very reliable stage. Nowadays, composite can make the same great result as amalgam filling material in restoring and is commonly used in both front and back teeth to help keep the natural appearance of the teeth and our smiles. This procedure is also called "bonding" because the material is actually bonded into place.

Amalgam Restoration
Amalgam restoration, also called a silver filling, is most commonly used in dental clinics to fix a decayed tooth and to restore its shape and function. This type of material can last a long time under huge pressure and acidic environment. It is cost effective and easy to use in a clinic. It has been the dominant type of filling material for many decades and is still used today.

Concerns About Amalgam
Some people are concerned about the toxicity of the amalgam used in the filling. But in fact, amalgam has been used successively for many many years in dentistry and has been tested continuously. There is no evidence showing that it is toxic. The Canadian Dental Association(CDA) states that there is no proof that dental amalgam poses any threat to the safety of the dental public. In fact the Royal College of Dental Surgeons of Ontario discourages the removal of amalgam filling for patient concerns over its toxicity. However, its replacement for aesthetic reasons is understandable.


A crown, commonly referred to as a "cap", covers on a tooth completely to restore the tooth's normal shape, size and function. When a tooth has been severely decayed, cracked or damaged, a crown is definitely needed.

Crowns are made by materials with strength and long durability, such as alloys of gold, porcelain, or combinations of both gold and porcelain. These materials can tolerate wearing and abrasion and keep crown functioning. These encompass the entire tooth so that no one part of it will chip off.

Stainless Steel Crown

Prefabricated crowns are often used by Dr. Fremeth when treating severely damaged baby teeth. This is a very common procedure for dentists who perform a high quality of care when treating a child's tooth. These should not be confused with much more costly custom made crowns used on permanent teeth but provide a similar service in extending the life of the tooth.


Generally, dentists use the term 'bridge' when referring to permanent tooth replacement. A bridge is one way that Dr. Fremeth can fill a gap created by a missing tooth or teeth. It consists of two dental crowns, one on either side of the gap, and a false tooth suspended where the gap is joining the two adjacent crowns together.

A modification of this procedure, known as a Maryland Bridge, can be used in cases where the teeth adjacent to the gap do not need crowns. In this case, after minimal polishing of these adjacent teeth a custom made bridge is simply bonded into place without extensively harming healthy tooth structure.


Dental implants are used to replace missing roots and support replacement teeth, which may be fixed to the implant(s) or you may be able to take them out yourself. Implants are not for everyone. You must be in good general health, have healthy gums and enough bone in your jaw to support the implant(s). You must be willing to see your dentist or dental specialist several times until the work is done, and take very good care of your implant(s). In addition, implants can cost more than other kinds of replacement teeth.

It's normal for bone to shrink if it no longer has teeth to support. Because an implant sticks to bone, the bone is less likely to shrink. But, if you have been missing teeth for some time, you may have lost bone. A bone graft can build up the bone so it can support an implant. When a bone graft is done, bone is added to the area where your jawbone has shrunk.

Step 1
Your dentist, oral surgeon or periodontist will put a small metal post into your jawbone.

Step 2
Over time, the post will bond with the bone around it.

Step 3
The post (or implant) will act like an anchor to hold one or more false teeth in place.

Because implants stick to the bone, false teeth attached to implants look and act much like natural teeth. But implants are not as strong as natural teeth. You must brush and floss your implant(s) very carefully. Be gentle, but make sure you brush all sides of your implant(s). A toothbrush that has longer bristles at the tip may help clean behind your implant(s). Floss very carefully at least once a day. You will need to be gentle with the floss where the implant meets the gum (called the gumline). You may find a floss threader useful for cleaning this area.


Veneers are very thin pieces of specially-shaped porcelain that are glued over the front of your teeth. They are the cure for teeth that are severely discolored, chipped, have small holes or pits, misshapen or crooked, or for the correction of unwanted or uneven spaces. Unlike crowns, veneers won't require the dentist to remove much of the tooth. Veneers are created from an impression taken in Dr. Fremeth's office and sent off to a laboratory technician. This procedure commonly takes several days, after which your custom veneer is then glued directly onto your tooth. Veneers won't stain, making them a very popular solution for many people seeking that perfect smile. The colour is selected to brighten dark teeth without the worry of them changing colour.

Tooth Whitening

Tooth whitening is a bleaching process that lightens discoloration and removes stains from the enamel and dentin of the teeth. Dr. Fremeth uses a mild solution retained in a custom filled mouth piece that is worn over your teeth for a short period during the day. Prior to beginning treatment, Dr. Fremeth will examine your teeth to determine whether you have any untreated cavities, tooth decay, or unhealthy teeth and determine if this is procedure is right for you. Then an initial colour shade is taken and recorded. A custom made tray is made by taking an impression of your teeth, which gives you a personalized tray and allows you to achieve optimum results. After several weeks your teeth are once again examined and a new lighter, colour shade of your teeth is taken.

Almost anyone can benefit from this safe procedure. Research and clinical studies indicate that whitening teeth with carbamide peroxide and/or hydrogen peroxide under the supervision of a dentist is safe for teeth and gums. In fact, many dentists consider this whitening process the safest cosmetic procedure available today. Tooth whitening is ideal for patients who have healthy, unrestored teeth and would like to have a whiter, brighter smile.
