Safe Dental Materials
Healthy Dentistry is a mercury-free dental practice as we believe that the use of mercury-containing amalgam fillings is potentially harmful to our patients. As such, we only use biocompatable resins. Contact us at (07) 3210 2055 to book a consultation.
At Healthy Dentistry, we insist on alternative and safe filling materials like porcelains and composite resins. These metal-free materials do not contain any toxic substances like mercury, hence are safer for use in the human body with minimum chance of allergic reactions or teeth sensitivity. The tooth-coloured restorations are also aesthetically pleasing while providing competent resistance to fracture and wear.
Mercury Free Dentistry
In the past, “silver” amalgam fillings containing mercury were the most commonly used material to repair and fill teeth. But that was then.
Amalgam is an alloy consisting primarily of Silver and Mercury. As a filling material that is placed in a person’s mouth for long periods – up to 10 years or more for many patients – its mercury content naturally attracts a lot of controversy.
Although considered safe when mixed in with the other metals in the filling, mercury is still a highly toxic heavy metal. The main concern revolves around the mercury vapours that get released into the mouth – and swallowed – every time the patient grinds or chews on the amalgam tooth. Over time, it is feared that the accumulation of mercury exposure can pose a serious health risk.
Healthy Dentistry is a mercury-free practice that uses white composite fillings for its tooth-coloured aesthetics and safe, metal-free properties.
The Healthy Dentistry Difference
Healthy dentistry only uses biocompatible, non-toxic dental materials that do not interfere with any of the body’s functions. Our modern and holistic dental centre in Brisbane is mercury-free and favours metal free filling materials. These include “white” compound resins called composite, ceramics, glass-based agents and porcelain, to name a few.
Metal free fillings and dental implants are better for you and offer a wealth of benefits, including:
Fillings are formulated to resemble the natural colour, function and lustre of existing teeth.
The dental procedure for placement of fillings is probably one of the most common that many of us can relate to. Most of us have had at least one or two fillings placed in our lifetime. If you had them placed some time ago, chances are, the dentist probably used amalgam fillings. One common complaint against the silver-coloured amalgam fillings is their dark appearance that draws attention to your mouth. If your amalgam fillings are placed in a prominent position, every time you speak, eat or smile, you are practically announcing to the world that you had cavities in the past.
In this regard, the aesthetic advantage of white fillings is obvious. White fillings contain a mixture of plastic and glass that can be used to restore teeth with decay or cavities. Patients prefer white fillings for their cosmetic, tooth-like appearance. Not only can they blend seamlessly to the colour and shade of surrounding teeth, they create a natural and more beautiful smile.
Ceramic or porcelain fillings, caps and crowns offer superior strength and durability, while still maintaining pristine aesthetics.
Composite fillings are generally made up of silica, ceramic (or porcelain) particles, and quartz and resin crystals. Given its aesthetic tooth-coloured appearance, composite resins were once exclusively used to reinforce the anterior (front) teeth from fracture. With the development of newer polymers, today’s composite resins are much more rugged, hence have become choice materials for molar teeth as well. Modern composite fillings help to prevent tooth fractures and misshapen teeth by conditioning and reinforcing the enamel of the tooth.
Metal is a thermal conductor. Patients with mercury fillings may experience sensitive reactions to hot or cold food and beverages. This is reduced with non-metal alternatives.
Silver amalgam fillings are known to expand when exposed to heat and contract when exposed to low temperature. That’s why when a large enough amalgam filling is placed near the nerves, tooth sensitivity can be an acute problem. On the other hand, white fillings are a poor conductor of temperatures, so do not expand or contract when the filled tooth comes into contact with hot/cold food and beverages. Due to its bonding process, composite fillings also help to reinforce the tooth structure. This helps to prevent fractures while also insulating the tooth from excessive temperature changes.
Schedule a dental assessment with Dr. Marhfour and his team today if you are experiencing any toothaches or sensitivities or would like to safely remove an amalgam filling. We look forward to keeping your teeth and health in tip-top shape.
