Dental Teeth Fillings

Dental methods to save your natural teeth from further decay

What are dental fillings?

Dental teeth fillings help fix cavities and tooth decay, which help to prevent further tooth decay, damage and tooth loss.

Teeth Fillings – Materials Used for Tooth Restorations

Different types of metals and resins are used in dentistry to replace and rehabilitate teeth structures. Plastic and resin teeth fillings are commonly used as restorative solutions and do not have adverse responses. Metal fillings can potentially have allergic or toxin reactions.

Types of Dental Fillings

Glass Ionomer

Glass Ionomer

Tooth-coloured, fluoride-containing plastic type filling. Glass Ionomer fillings are not strong and break down quickly. The average longevity is around ten years.

Suitable for fillings in kids’ teeth, as a temporary filling, or in a patient with a lot of decay.

Glass ionomer is applied to caries affected dentin. The result helps minimise the amount of natural tooth required to restore the tooth compared to standard composite resin.

Composite Fillings (plastic – acrylic resin)

Composite resin is the first line of defence for damaged, fractured teeth. Composite fillings are a cost-effective and highly utilised method to treat cavities.

The process involves the removal of the decayed material from the natural tooth and then restoring the tooth with composite resin.

Average longevity 10-15 years; tooth-coloured; moderate cost; best-used in small-to-medium-size restorations for any teeth; direct one-day placement.

dental inlays

Gold Inlays and Onlays

Inlays and Onlays are conservative methods of restoration. It is the process whereby the restoration sits on the outer layer of the tooth.

Unlike a standard dental crown, which requires the more natural tooth to be removed and sculpted, “Inlays and Onlay” tend to require a minimum amount of the tooth structure to be removed.

  • Average longevity from 20 years to life
  • Gold colour
  • Moderate-to-high initial cost
  • They are applied for any size restoration in any location where metal is not displayed.

Ceramic Indirect (Porcelain Inlays/Onlays)

Porcelain ceramic Inlays and Onlays look natural and are durable, just like the average tooth. As their reference implies, they either sit ‘in’ or ‘on’ a tooth.

Inlays are an alternative option to silver and composite fillings. They are less invasive than dental crowns since less of the tooth is trimmed or shaped for preparation.

Onlays restore teeth with large dental fillings due to decay or damage. In contrast to Inlays, Onlays will cover the cusp of the tooth.

Average longevity 10-15 years; tooth-coloured; moderate-high initial cost; best in moderate-sized restoration for any teeth; two-appointment placement.

Dental Amalgam

Dental amalgam

Dental Amalgam is a mixture of metal and chemical properties. Fillings that used amalgam were once common but superseded by more conservative and conventional tooth coloured procedures. Amalgam fillings are less common now than in the past. They are often referred to as ‘silver fillings due to their noticeable aesthetic appearance.

Used for over 10o years, Silver Amalgam is an alloy containing silver, tin, copper, zinc, and about 50% mercury. It has been highly successful but is an unsightly material.

Since its inception, using mercury in the body has been criticised, but Amalgam use is still supported strongly by the Australian Dental Association and other groups worldwide.

A small percentage of people in the overall population may be allergic to the elements in silver amalgam. You do have several options, which are defined below.

Crowns or Fixed Prosthesis

Gold alloys have been used for many years for the construction of crowns or fixed bridges. They provide excellent, strong, long-lasting service. Two major types of alloys are now available:

High Noble Metal

Mostly gold, also palladiums, silver; occasionally platinum, zinc, copper.

Base Metal

Mostly nickel also chrome or cobalt and other base metals.

All of the above metals are used either as the sole constituent of a crown, or as a base on which porcelain is fired (baked). Most people have no biologic response to the base metals.

If you have known allergies to metals, please tell us. We usually use high-noble metals. The cost of these is somewhat higher than base metals.

Porcelain Only Crowns

Pure porcelain crowns are now being used more extensively in aesthetic areas.

Which type of tooth restoration is best for you?

Your dentist will give you advice and advantages and disadvantages of each type to allow you to make an informed decision.

The best type for you will depend on how big the restoration is, whether it is in a visible part of the mouth and cost.

A dentists goal is to save the natural tooth. Unfortunately if extensive decay has occurred additional treatments might be recommended. These may include Root Canal Therapy, if decay along with the infection has traveled to the root of your tooth. Therefore affecting the gum. Another method to treat extensive decay or break down of the tooth is to recommend a dental crown.

How long do dental fillings last?

With correct oral hygiene and regular routine dental check-ups, dental fillings can last anywhere between 7-20 years. The reason behind the variance is due to unforeseen lifestyle factors. Additional influences may include:

  • Food and drink eating habits
  • Dental hygiene (brushing, flossing, use of mouthwash)
  • Trauma or high impact to the area
  • Decay surrounding the filling
  • Grinding of teeth

Do dental fillings need to be replaced?

Only in instances of damage or deterioration should a dental filling be replaced. Unfortunately, not doing so may lead to decay to the natural treated tooth area.

Fillings tend to cover the exposed tooth enamel that has been damaged. Therefore neglecting treatment could expose further damage throughout the tooth and eventually the root, which may require root canal therapy. In most severe cases, if decay or infection has effected most of the tooth, an extraction might be recommended.
