Protect your teeth from further damage with dental fillings

You only get one set of adult teeth, so why not protect them for as long as possible? Dental fillings, as well as inlays and onlays, are used to protect teeth that have suffered from decay or minor chips and cracks.

What are dental fillings for?

Dental fillings are used as a restorative option for decayed teeth. After the decay is scraped from your tooth, the space is filled with a composite resin material for a natural looking restoration.

How are dental fillings done?

The process for dental fillings takes two appointments.

First appointment

The first appointment is your consultation. This is where you will have you check-up and clean. Part of your check-up is having digital x-rays taken of your teeth. While sometimes decay is obvious to the naked eye, it’s always better to get a more detailed, accurate viewing with digital x-rays.

If decay is present on the x-ray your Dream Smiles dentist will advise what they think is the best course of action for your oral health. The advantage of a filling is that all the decay is removed and replaced with composite resin. This is advantageous because it can help to prevent the decay spreading and causing worse issues. These worse issues include infected root canal which—if left untreated—can lead to abscesses and other complications.

Second appointment

Your second appointment is where your dentist will clean the decay out of your tooth and be replaced with a composite resin. This material is colour-matched to your teeth so it will blend in. Which is another advantage of dental fillings. Especially of composite resin fillings. Not only are they effective, they look good and don’t have the draw backs of mercury fillings.

A light will be applied to the filling so that it hardens, and once this is done your treatment is complete.

Is mercury still used in dental fillings?

Some dentists still use mercury fillings. Dream Smiles does not. And while the debate is still going about mercury fillings, there is enough evidence to suggest composite resin fillings are a healthier, long-lasting option.

The established problem with mercury fillings are:

  • The mercury can stain your teeth.
  • Compared to composite fillings, mercury fillings require a lot more healthy tooth structure to be removed.
  • Decay can actually form underneath a mercury filling.
  • Mercury fillings expand and contract with vary temperatures—which has been known to cause cracked teeth.

These are just some of the reasons Dream Smiles prefer to provide our patients with composite resin fillings.

How long do tooth fillings last?

Composite resin fillings can last between 5 and 7 years. Like all restorative treatments, how well you take care of your oral health plays a role in the life of a dental restoration.

Keep your teeth healthy with dental fillings from Dream Smiles

It’s quite common for there to be no symptoms of tooth decay. If the decay’s severe you may notice some sensitivity to hot and cold food, as well as discomfort when you chew. Discoloured gums can be another sign something is not right beneath the surface.

By visiting Dream Smiles every six months for regular check-up and clean we can catch any problems before they become too big. For more information, or to request an appointment, contact us today.


In many cases, there are no symptoms of tooth decay but if the decay is severe enough you may notice some sensitivity to hot and cold foods and drinks. You may also feel some discomfort when you chew and bite down. Sometimes, discoloured gums could be a sign that there is something not right beneath the surface, so it is a good idea to come in for a check-up if you notice anything out of the ordinary.

Mercury fillings can stain your teeth, and can also expand and contract with varying temperatures, which means that they can cause teeth to crack. It is also possible for decay to form underneath a mercury filling.

It generally takes two appointments to have a dental filling placed. In the first appointment, you will have a consultation with your dentist, while the second appointment will involve a process in which the decay is cleaned out of your tooth and replaced with a composite resin. The resin is colour-matched to your teeth so that it looks natural. A light is applied to the filling material so that it hardens in place.
