When are Dental Fillings Required?

While a trip to the dentist is usually never fun, sometimes it’s necessary to keep your smile looking, feeling and functioning at its best. One of the most common reasons people need dental care – aside from regular cleanings, of course – is because they need a filling. Fillings are a common form of dental surgery and are often used to treat things like tooth breakage, cavities or other kinds of damage. There are several reasons your dentist might suggest you undergo one, and we’ll take a closer look at what some of those reasons may be. But first, a primer on fillings: a filling is a method of restoring function and shape to a tooth that’s been damaged by cavities, trauma or other dental problems. The filling is packed into or around the damaged tooth; after any decayed material has been cleaned out of course. Fillings come in many different materials, and your Toronto dentist or dental surgeon will decide what is best for you. These materials include porcelain, gold, alloy metal or composite resin, which is matched to the colour of your existing teeth.  Here’s when your Toronto dentist might suggest you get a filling: Tooth filling

Your Tooth Shows Signs of Decay

The most common reason for needing a filling is tooth decay. This is frequently caused by cavities. When a tooth starts to rot, it will decay the tooth, leading to sensitivity, pain and more serious dental problems, including infection or an abscess. To stop the decay from progressing, your dentist will clear out the infected portion and apply the filling, which will help the shape of your tooth and prevent any bacteria or food remnants from getting stuck in there.

Enamel Loss

The enamel on the surface of your teeth has a really important function. It protects your teeth from wear and tear, pain and sensitivity. Over time, you can lose the enamel. Sometimes this is caused by abrasion, other times it is caused by damage or trauma. Without enamel, your teeth are more prone to sensitivity from hot or cold substances, as well as cavities. If your teeth are starting to lose enamel, your Toronto dentist may suggest a filling to protect the tooth from further enamel loss.


Tooth trauma is one of those nails-on-a-blackboard scenarios that nobody likes to think about. It does happen, however, and depending on the nature of the trauma, can damage your tooth in a way that requires a filling. If a portion of your tooth breaks or chips, for example, a porcelain or composite filling might be required to restore a normal shape to the tooth and prevent further breakage. This can also be the case with tooth cracks, which can be caused by trauma, weak teeth or by biting down on something extremely hard. Grinding your teeth at night can cause this problem as well. A filling can prevent the crack from expanding or weakening the tooth further.

Replacing an Older Filling

Over time, it is possible for fillings to wear down, break or get lost completely. This is particularly true for older fillings that may have been installed at a time when dental technology and the materials dentists had access to were limited. It may be that the filling material that was used wasn’t a good match for the nature of the original problem. Your dentist may suggest an alternate material or a different type of filling in this case. Tooth filling

How Will I Know if I Need a Filling?

The key to good dental health is regular maintenance. If you’re seeing a dentist regularly, he or she should be able to catch dental issues early, if possible. Some things, like a tooth chip, are unavoidable. However, many filling causes – like cavities – begin without any visible signs or pain, so regular dental maintenance will catch them before they spiral into an even bigger – and more painful – problem. You might need a filling if you experience any of the following:
  • tooth pain, either a consistent ache or a sudden sharp pain
  • sensitivity to heat, cold or pressure
  • noticeable holes or gaps in your tooth that are either visible or can be felt
  • pain while eating or chewing, especially in a localized area
  • a dark shadowing or other mark on a tooth
  • a sharp or rough surface on a tooth that wasn’t there previously.
  • you’ve noticed a previous filling has fallen out
