How To Tell If You Need a Dental Filling

When you have a cavity a dental filling may be used to fix the damaged tooth. Here, our Riverdale Toronto dentists explain how to tell if you may need a dental filling, and the various types to consider.

About Dental Fillings

These very common dental restorations are used to restore the structure, function and appearance of a tooth that's been damaged or decayed, alleviating tooth pain you may be experiencing.

Why Fillings Are Used

Tooth fillings can fix fractures, cracks, or tooth decay. They help restore functionality to your tooth and in some circumstances, dental fillings can be used to make cosmetic improvements to your smile. 

Signs You Need A Filling

While the only way to know for certain if you need a dental filling is to see a dentist, there are a number of signs that could indicate that you need to have a cavity filled. If you experience any of these, schedule an appointment with your dentist:

    1. You feel a sharp or throbbing pain in your tooth.
    2. You notice a hole or dark spot on one of your teeth. 
    3. Your tooth is broken or chipped. 
    4. Your tooth feels rough to the touch. 
    5. Food keeps getting stuck between certain teeth. 
    6. An existing tooth filling looks or feels broken or cracked. 
    7. You've lost a tooth filling and need a replacement.

    Types Of Dental Fillings

    Dental fillings can be made of several materials, from amalgam to composite, porcelain and gold. While each of these materials is safe and long-lasting, they also each have their advantages and disadvantages when it comes to repairing a cavity or decay. Here, our dentists provide advice on how to make the right dental choice for you. 

    Porcelain Fillings for Strength & Appearance

    Also called inlays and onlays, porcelain fillings are brittle, hard, and made in combination with metal. Made in a dental lab and sent back to your dentist to place, these strong, tooth-coloured dental restorations are typically used on molars as they are more durable and longer lasting than a regular dental filling. 

    You’ll usually need to attend two dental appointments so your porcelain filling can be placed in your mouth.

    Composite Fillings for a Natural Look & Feel

    Composite fillings are created to look very similar in colour to the surrounding natural teeth, meaning that they blend in and help to give you a natural looking smile.

    They look and feel natural, and are popular with patients who are concerned with how silver amalgam fillings may appear on teeth that are visible when they smile.

    Dentists like composites because they are easy to sculpt and shape onto a tooth, and bond naturally to a tooth. This means your dentist won’t need to remove as much existing enamel when preparing the tooth for the filling.

    Your dentist will remove tooth decay and add bonding material to the inside of the hole so the filling can be placed. Composite resin is then layered in the hole.

    A curing light is used to harden each layer. When the last layer of resin has hardened, the filling will be carefully shaped to match your natural teeth.

    Gold Fillings for Durability 

    Cast gold fillings are made using a model of your tooth. Created from a mix of gold combined with other materials such as copper and silver, a cast gold filling is created in a dental lab and sent back to your dentist.

    It will then be cemented in place inside your mouth. Though this type of filling is considered the most durable (typically lasting 20 years or more) they can also be the most costly. You'll also require at least two dental appointments to have it placed.
