For over three decades, veneers have helped mask dental imperfections like chipping, staining or gaps and improve the appearance of millions of teeth. As the name implies, this thin layer of porcelain covers a tooth's visible surface and accurately mimics the texture, color and translucence of natural teeth.
Veneers could be just the solution you need for a more attractive smile. But before you begin treatment, be sure you have these 3 essentials in place to ensure a successful outcome.
True expectations. While the transformation of a tooth's appearance with a veneer can be astounding, veneers in general do have their limitations. You need an adequate amount of the tooth's structure present for a veneer to properly adhere — if not, you may need to consider a porcelain crown instead. Likewise, gaps and other misalignments may be too great for a veneer to cover: in that case, you should consider orthodontics. A thorough examination beforehand will determine if veneers are the best option for you.
An artisan team. Every veneer is custom made to match an individual patient's tooth shape and color, handcrafted by a skilled dental technician. There's also an art to the dentist preparing the tooth beforehand and then properly positioning the veneer for bonding to achieve the most attractive result. Be sure, then, that your veneer "team" comes highly recommended by others.
The best materials. The first porcelains were powdered glass ceramics mixed with water to form a paste. Technicians shaped the paste in successive layers and as it oven-cured it took on the beautiful translucence of natural teeth. Unfortunately, this type of porcelain could be brittle and prone to shattering when subjected to heavy biting forces. In recent years, though, we've begun to use ceramics reinforced with other materials like Leucite for added strength. Today, the materials dentists use have much better durability.

Your gums not only help hold your teeth securely in place, they also help protect them. They're also part of your smile — when healthy and proportionally sized, they provide a beautiful frame for your teeth.
But if they become weakened by periodontal (gum) disease, they can detach and begin to shrink back or recede from the teeth. Not only will your smile be less attractive, but you could eventually lose teeth and some of the underlying bone.
Treating gum recession begins with treating the gum disease that caused it. The primary goal is to remove the source of the disease, a thin film of food particles and bacteria called dental plaque, from all tooth and gum surfaces. This may take several sessions, but eventually the infected gums should begin showing signs of health.
If the recession has been severe, however, we may have to assist their healing by grafting donor tissue to the recession site. Not only does this provide cover for exposed tooth surfaces, it also provides a “scaffold” for new tissue growth to build upon.
There are two basic surgical approaches to gum tissue grafting. One is called free gingival grafting in which we first completely remove a thin layer of surface skin from the mouth palate or a similar site with tissue similar to the gums. We then attach the removed skin to the recession site where it and the donor site will usually heal in a predictable manner.
The other approach is called connective tissue grafting and is often necessary when there's extensive root exposure. The tissue is usually taken from below the surface of the patient's own palate and then attached to the recession site where it's covered by the surrounding adjacent tissue. Called a pedicle or flap, this covering of tissue provides a blood supply that will continue to nourish the graft.
Both of these techniques, but especially the latter, require extensive training and micro-surgical experience. The end result is nothing less than stunning — the tissues further rejuvenate and re-attach to the teeth. The teeth regain their protection and health — and you'll regain your beautiful smile.

One of the top concerns in public health today is exposure to the metallic element mercury within the environment. At abnormal levels, mercury can have a toxic effect on our nervous systems and cause other health problems.
These concerns over mercury have also increased attention on one material in dentistry that has included the metal in its makeup for over a century — dental amalgam for filling teeth. Amalgam is a metal alloy that can include, in addition to mercury, silver, tin, and copper. When first mixed dental amalgam is a moldable material used for fillings in prepared teeth. It then hardens into a durable restoration that can withstand biting forces.
While the use of amalgam has declined with the introduction of life-like colored fillings, it's still used for teeth like molars subject to high biting forces. With what we now know about the ill effects of mercury (which can make up to half of an amalgam mixture) is it safe to continue its use?
The American Dental Association has performed extensive research into amalgam safety. They've found that mercury is stabilized by the other metals in the amalgam. This prevents "free" molecules of mercury, the real source of harm to health, from escaping into the blood stream in the form of vapor. Although trace amounts of mercury vapor from the amalgam are released as a person chews, those levels are well below the threshold that could cause harm.
From a patient standpoint, the biggest drawback to dental amalgam isn't safety — it's the appearance of teeth it's used on. Silver fillings aren't considered attractive. And now there are viable filling alternatives that not only look like natural teeth but can withstand biting forces almost as well as amalgam. These materials include composite resins, mixtures of glass or quartz within resin, or glass and resin ionomers. Each of these has advantages and disadvantages depending on how and where they're applied.
After a thorough dental examination, we'll be able to advise you on what filling material will work best to produce the best result. And if we do suggest dental amalgam you can rest assured it will be a safe choice.
